Paul, my congrats to the good result. I think it is not necessary to confirm that the message is correct :-)
So the diurnal phase changes are uncritical on our path? Or could it be extremely different?

Markus, thanks for the note. I stopped the TX manually. I fear the problem was that SpecLab restartet the psk.txt file at 16:00:02 today, i.e. after 24 hours. Periodic actions, you know.

Paul, Stefan,
 
great, congratulations both!
 
Strange that according to Stefan's forest grabber the PSK transmission was carrying on long after the scheduled end of sequence (19:01:22 ?).
 
Will now attempt to decode here as well.
 
All the best,
Markus

I was impatient, with still 5549.6 seconds left
to go I decoded the message easily,

'CQ CQ DREAMERS BAND DE DK7FC IN JN49IK PSE KK'

Carrier S/N: 25.03 dB in 10.3 uHz
Eb/N0 = 0.1dB with constant reference phase. I'll
let the decoder go through a full phase search, it
may find a better decode with a phase pattern that
is closer to the diurnal. Later I'll decode the
full transmission, we should get a better Eb/N0.

That must be one of the longest messages decoded.
Only needed 1.8 GByte RAM so within reach of home
PCs.

... decoder has finished the phase search. No
improvement on the 0.1dB so looks like LWPC is close
to the mark with its phase prediction.

There's not so much margin left. What would hve been the shortest symbol length to get a decode on your side? And can you tell something about the signal stability? 25 dB in 10 uHz looks ufb. I'm using that E field pick up probe to feed back the radiated signal to the soundcard, so the whole system (soundcard, PA, coil, antenna wire) becomes part of the PLL. The probe is a simple unshielded piece of RG174 cable, abt 0.1 m long, in a distance of 1m to the antenna wire. so far i have no idea if this improves the phase stability or maybe even reduce it? I saw no announcements for a transmission by DF6NM, DL3NDR or DJ8WX (why are only German stations transmitting on VLF these days?) this morning and it is sunday, so i started a simple carrier transmission at 07.05 UTC at 8270.00500 Hz. The low QRN period must be used :-) And, Gary/G4WGT has started a 47 uHz SL instance on his VLF grabber. Maybe i can leave a small trace there this morning. 73, Stefan Am 01.05.2016 07:51, schrieb Paul Nicholson: > > After the full message duration had elapsed, > Eb/N0 came to +1.6 dB, > > Phase: 180 180 150 150 > > Carrier S/N: 24.96 dB in 10.3 uH > > Were the last 3 hours corrupted?

Hi all,
yeste= rday I completed a first step for an online dreamer band grabber.
You can find my shared real time archive here: ik0vve dropbox
At the mome= nt the antenna is a 60 wires 1sq meter loop, a little low noise pre and S= L locked on Italian LF ICV station.
Direction is N/S.
Of course I'll do some improvement in the next days, I would try to bett= er tune the antenna.

I am in awe of Ebnaut and SpecLab, but find them both daunting applications. I would love to see what i can receive on VLF, but unless something akin to what you are suggesting appears I feel I would be a bit (a lot, probably) out of my depth with both applications. I hope some clever people can find the time and desire to create something a lot more user friendly to set up as an operating system for VLF. If they do I would, for sure, be keen to give it my best shot.

No activity from the UK for a couple of years I think. Not sure we can blame the need for a Notice of Variation, it isn't very difficult to apply for. The T/A east to west is still waiting to be done and the UK has a geographic advantage there. I would have thought it the sort of thing a radio club could field a team for. -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Sun May 1 14:59:58 2016 Return-Path: X-Spam-DCC: paranoid 1290; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-0.7 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, RATWARE_GECKO_BUILD,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u41CxvMr011533 for ; Sun, 1 May 2016 14:59:57 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1awquh-0000cq-Qb for rs_out_1@blacksheep.org; Sun, 01 May 2016 13:55:55 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1awquh-0000ch-4C for rsgb_lf_group@blacksheep.org; Sun, 01 May 2016 13:55:55 +0100 Received: from mout01.posteo.de ([185.67.36.65]) by relay1.thorcom.net with esmtps (TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256) (Exim 4.87) (envelope-from ) id 1awquf-0005Dr-Ih for rsgb_lf_group@blacksheep.org; Sun, 01 May 2016 13:55:54 +0100 Received: from dovecot03.posteo.de (dovecot03.posteo.de [172.16.0.13]) by mout01.posteo.de (Postfix) with ESMTPS id 049BF20AC6 for ; Sun, 1 May 2016 14:55:49 +0200 (CEST) Received: from mail.posteo.de (localhost [127.0.0.1]) by dovecot03.posteo.de (Postfix) with ESMTPSA id 3qyS915bl4z5vMp for ; Sun, 1 May 2016 14:55:49 +0200 (CEST) Message-ID: <5725FCD5.40606@posteo.de> Date: Sun, 01 May 2016 14:55:49 +0200 From: DK7FC User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.8) Gecko/20100227 Thunderbird/3.0.3 MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org References: <1545cc43544-7b51-40b@webprd-a09.mail.aol.com> <57222E30.1080202@posteo.de> <57225653.3090907@abelian.org> In-Reply-To: <57225653.3090907@abelian.org> X-Scan-Signature: f38d515a9cad1e977fcfe251941a8120 Subject: ULF: EbNaut transmissions on lower frequencies?

If we assume the phase is much more stable on lower frequencies then 8.27 kHz, then it may be worth to experiment there, in slower modes. The most important system is, in my opinion, that stable transmissions can be done at any time! I sent 45 characters to you over 850km distance within 24 hours. 24 hours is nothing! It could have been 4 days, no problem! I still have 2 yoghurt cups ready to be added to the coil, no problem to go down another kHz. And i've ordered these 100x 3C85 cores! I'm really looking forward to experiment with them. With these cores it will be no problem to go down to 4 kHz. The question is which antenna current i can get with them. Maybe even 3 kHz is possible. Oh yes, let us try 2.97 kHz, OK? That's ULF! Sounds not realistic? A dream into a dream, you know?! 2.97 kHz, that's a distance of just 1.7 lambda to DF6NM and 8.8 lambda to Paul... My antenna has 114 kOhm reactance there, so 150 mA is no problem. That's about -5 dB over the current current. The radiation resistance falls by another 9 dB. So the signal will be 14 dB weaker? Sounds managable. Sferics are weaker below 5 kHz or so. Is it just due to propagation and will a amateur radiated signal over < 1000 km suffer from the same loss in propagation so the SNR stays the same, apart from the weaker signal? 73, Stefan From owner-rsgb_lf_group@blacksheep.org Sun May 1 16:10:37 2016 Return-Path: X-Spam-DCC: paranoid 1290; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-0.5 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, FORGED_RCVD_HELO,RATWARE_GECKO_BUILD,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u41EAaM7011679 for ; Sun, 1 May 2016 16:10:36 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1aws17-0000me-Qy for rs_out_1@blacksheep.org; Sun, 01 May 2016 15:06:37 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1aws17-0000mV-Al for rsgb_lf_group@blacksheep.org; Sun, 01 May 2016 15:06:37 +0100 Received: from parrot.netcom.co.uk ([217.72.171.49]) by relay1.thorcom.net with esmtp (Exim 4.87) (envelope-from ) id 1aws15-0005Nb-Ql for rsgb_lf_group@blacksheep.org; Sun, 01 May 2016 15:06:36 +0100 Received: from pn.abelian.org (i-194-106-52-83.freedom2surf.net [194.106.52.83]) by parrot.netcom.co.uk (Postfix) with ESMTP id B2B673273E4 for ; Sun, 1 May 2016 15:05:20 +0100 (BST) Received: from [127.0.0.1] (localhost [127.0.0.1]) by pn.abelian.org (Postfix) with ESMTP id 391CC4000D7 for ; Sun, 1 May 2016 14:06:34 +0000 (UTC) To: rsgb_lf_group@blacksheep.org References: <1545cc43544-7b51-40b@webprd-a09.mail.aol.com> <57222E30.1080202@posteo.de> <57225653.3090907@abelian.org> <5725FCD5.40606@posteo.de> From: Paul Nicholson Message-ID: <57260D6A.3040503@abelian.org> Date: Sun, 1 May 2016 14:06:34 +0000 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Thunderbird/38.6.0 MIME-Version: 1.0 In-Reply-To: <5725FCD5.40606@posteo.de> X-Scan-Signature: 7aa9ad08848e488e22e0ff1d71f4ef1d Subject: Re: ULF: EbNaut transmissions on lower frequencies?

Near those frequencies, dispersion will introduce large and variable phase delay. So avoiding the resonances, and times of geomagnetic disturbance, and stormy weather in Europe, and being able to tx and rx for as long as necessary with reliable equipment, it should be possible even with 14dB weaker signal.

Oggetto: LF: testing VLF grabber


Hi all,
yesterday I completed a first step for an online dreamer band grabber.
You can find my shared real time archive here: ik0vve dropbox
At the moment the antenna is a 60 wires 1sq meter loop, a little low noise pre and SL locked on Italian LF ICV station.
Direction is N/S.
Of course I'll do some improvement in the next days, I would try to better tune the antenna.

RR,

OK!
Do we know enough about the phase behaviour on 8.27 kHz, so we know where we are starting from?
For ULF we would need longer symbol periods, that's sure. So it could be interesting first to try 200s periods and a shorter message. 5 characters should be a goal, suitable for a few callsigns of active amateur radio stations :-)

5 characters at 200s symbols, that's 28 hours and 26 minutes and 40 seconds.

I will start a transmission at that rate (this time without SL restarting after 24 hours) and at 6 dB lower power (because of the beeeeeeep during the working day tomorrow). 6 dB less (abt 125 mA) should be no problem at that rate.
A first pre-test.

The cavity resonances are the frequencies seen as a horizontal (diurnal frequency variation) line in this capture from last year: https://dl.dropboxusercontent.com/u/19882028/VLF/dk7fc_VLF_150718_1326.jpg

It is heavier than air, so would keep Oskar filled as it were water Other options may be CO2 or N2. The goal should be to remove any moisture (water in air) Vacuum should work. But if the pump is very poweful you can get an slim Oskar and a flatened Coil :( So. Don't frill Oskar bottom yet !!!

Ich nehme Paul auch noch ins CC. Ich kann dich voll verstehen! Mir ging es früher genauso, ich wollte Amateurfunk machen und nicht rumprogrammieren. Nur durch den häufigen Kontakt mit Markus am Telefon wurde ich ufb in SpecLab eingewiesen, so dass ich mich eigentlich nie ärgern musste was nicht hinzubekommen. Das ist wohl Luxus. Und das hat mein Verständnis erweitert, so dass ich bei neuen Herausforderungen jetzt selbst zurecht komme. Ich konnte mich dann auch in den Raspberry Pi einarbeiten, ganz ohne Markus, und dort meine Zielanwendungen realisieren, selbst programmieren, zum Beispiel meinen Akkuspannungsplot vom Baum, auf der MF remote grabber Seite, falls du die kennst. Jetzt hab ich auch Spaß an solchen Programmierereien, das Interessensumfeld hat sich erweitert... Ich versuche Markus und Paul längst davon zu überzeugen, dass die neuen Versuche zwar spannend sind, wir uns aber keinen Gefallen tun wenn wir immer speziellere Anwendungen und manuelle Schnittstellen zwisachen SpecLab und EbNaut benötigen. Das mag für Paul und Markus und dann auch mich, bzw. den wenigen gut beratenen OMs kein Problem sein aber viele OMs werden mit dem ganzen Kram erst garnichts anfangen, weil sie garnicht wissen wie sie anfangen sollen, help-file hin oder her. Daher machen wir den großen Fehler ein potenziell vorhandenes riesengroßes Potenzial von interessierten Empfängern und oder Sendern nicht zu nutzen. Wenn es auf VLF derzeit quasi nur 5 Stationen gibt die etwas machen, dass wird die Aktivität auf Dauer nicht anhalten und wieder verebben. Deswegen müssen wir uns fragen - und zwar aus der Perspektive der anderen, nicht mit unserem eigenen Durchblick - wie wir die anderen ins Boot holen. Denken wir an EA5DOM! Luis hat Zugriff auf 2 Hochhäuser und kann zwischen denen einen Draht spannen. Er hat viel Motivation, eine Seltenheit! Es gibt viele Leute von denen da draußen aber manche brauchen etwas mehr Aktivierungsenergie :-) Das gilt auch für die Empfängerseite, da gibt es sicher Leute mit exzellenten Empfangsstandorten und genug Platz. Wir könnten ganz andere Projekte zusammen realisieren, ungenutztes Potenzial! Vielleicht gibt es noch einen 'Luis' da draußen, meinetwegen in Polen, der hat auch 2 Hochhäuser und könnte dort was aufbauen und interessante Experimente machen. Aber vielleicht denkt der sich "Och für die 3 Sender da unten fang ich mir die Arbeit nicht an". Tja schade! Eine wichtige Anregung finde ich, dass es dieses Grabberfenster gibt, wie bei OPDS. Das ist eine dauerhafte Herausforderung. Es werden viele Leute den Drang erleben in dieser Liste zu stehen! Es ist wie mit meiner Bake auf MF um Weihnachten 2014. Die Bake lief 3 Tage ununterbrochen. Im Bakentext habe ich nach Rapporten gefragt und meine Emailadresse genannt. Ich habe dann dutzende (!!) Emailrapporte bekommen, weil die OMs ihr eigenes Rufzeichen im Bakentext hören wollten, auf Mittelwelle, einem neuen Band für die meisten! Und das war der Ansporn. Allein wegen dieser einen Aktion kamen in der Folge viele neue Stationen aufs 630m Band! Und genau so kann das auch auf VLF gehen! So, und ich hab auch noch eine zusätzliche Lösung: Wir brauchen* tutorial videos*, Videoanleitungen auf YouTube! Keiner hat doch richtig Lust sich die SpecLab Hilfe reinzuziehen wenn er vol 0 startet und schon über 60 ist, die wenigsten zumindest. Bei YouTube gibt es für jeden Scheiss ein Video, z.B. "Wie wechsle ich eine Fahrradkette" oder "Wie bekomme ich beim Arduino eine LED zum blinken"... Das ist die moderne Welt! Und genau das brauchen wir auch für SpecLab und EbNaut und die Schnittstellen dazwischen. Das ganze in mehreren Episoden, vom Download bis zur Konfiguration eines QRSS3 grabbers etc etc. Und auch den Fileexport für EbNaut. Dann ist es doch egal wie kompliziert es ist, man kann einfach Schritt für Schritt gezeigt bekommen wie es geht und nochmal "zurückspulen" oder anhalten wenns zu schnell ging etc etc. In Deutsch wäre das kein Problem, in Englisch könnte ich das eigentlich auch machen. Das sollte ich mir mal zur Aufgabe machen. Müsste man vorher vielleicht genau strukturieren, was man da in welche Episode packt. Ich msste mir dann erstmal einen YouTube account zulegen und lernen wie man Videos uploaded aber das müsste ja alles machbar sein. Ach, weisste was, ich kopiere die Mail gleich noch an den Reflektor, die anderen OMs können es sich ja übersetzen lassen, die neugierigen :-) Jetzt mal endlich zusammen arbeiten. Die Mail kann ja auch aAnregung sein. Und wenn ich sie nur im ganz kleinen Kreis verschicke dann ist das evtl. auch wieder ein Beispiel für ungenutztes Potenzial. Denken wir an DG3LV, den könnte ich mir auch vorstellen. Was meinste wenn der das hier ließt! ;-) Oder DL6II, der steht schon in den Startlöchern! Also, Roland, da geht was! Bleib mal am Ball. Wir machen das schon. 73, Stefan --------------000203090609090201000206 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 8bit Hallo Roland,

Es gibt viele Leute von denen da draußen aber manche brauchen etwas mehr Aktivierungsenergie :-) Das gilt auch für die Empfängerseite, da gibt es sicher Leute mit exzellenten Empfangsstandorten und genug Platz. Wir könnten ganz andere Projekte zusammen realisieren, ungenutztes Potenzial!
Vielleicht gibt es noch einen 'Luis' da draußen, meinetwegen in Polen, der hat auch 2 Hochhäuser und könnte dort was aufbauen und interessante Experimente machen. Aber vielleicht denkt der sich "Och für die 3 Sender da unten fang ich mir die Arbeit nicht an". Tja schade!

Eine wichtige Anregung finde ich, dass es dieses Grabberfenster gibt, wie bei OPDS. Das ist eine dauerhafte Herausforderung. Es werden viele Leute den Drang erleben in dieser Liste zu stehen! Es ist wie mit meiner Bake auf MF um Weihnachten 2014. Die Bake lief 3 Tage ununterbrochen. Im Bakentext habe ich nach Rapporten gefragt und meine Emailadresse genannt. Ich habe dann dutzende (!!) Emailrapporte bekommen, weil die OMs ihr eigenes Rufzeichen im Bakentext hören wollten, auf Mittelwelle, einem neuen Band für die meisten! Und das war der Ansporn. Allein wegen dieser einen Aktion kamen in der Folge viele neue Stationen aufs 630m Band! Und genau so kann das auch auf VLF gehen!

So, und ich hab auch noch eine zusätzliche Lösung: Wir brauchen tutorial videos, Videoanleitungen auf YouTube! Keiner hat doch richtig Lust sich die SpecLab Hilfe reinzuziehen wenn er vol 0 startet und schon über 60 ist, die wenigsten zumindest.
Bei YouTube gibt es für jeden Scheiss ein Video, z.B. "Wie wechsle ich eine Fahrradkette" oder "Wie bekomme ich beim Arduino eine LED zum blinken"... Das ist die moderne Welt! Und genau das brauchen wir auch für SpecLab und EbNaut und die Schnittstellen dazwischen. Das ganze in mehreren Episoden, vom Download bis zur Konfiguration eines QRSS3 grabbers etc etc. Und auch den Fileexport für EbNaut.
Dann ist es doch egal wie kompliziert es ist, man kann einfach Schritt für Schritt gezeigt bekommen wie es geht und nochmal "zurückspulen" oder anhalten wenns zu schnell ging etc etc.

In Deutsch wäre das kein Problem, in Englisch könnte ich das eigentlich auch machen. Das sollte ich mir mal zur Aufgabe machen. Müsste man vorher vielleicht genau strukturieren, was man da in welche Episode packt. Ich msste mir dann erstmal einen YouTube account zulegen und lernen wie man Videos uploaded aber das müsste ja alles machbar sein.

Ach, weisste was, ich kopiere die Mail gleich noch an den Reflektor, die anderen OMs können es sich ja übersetzen lassen, die neugierigen :-) Jetzt mal endlich zusammen arbeiten. Die Mail kann ja auch aAnregung sein. Und wenn ich sie nur im ganz kleinen Kreis verschicke dann ist das evtl. auch wieder ein Beispiel für ungenutztes Potenzial. Denken wir an DG3LV, den könnte ich mir auch vorstellen. Was meinste wenn der das hier ließt! ;-) Oder DL6II, der steht schon in den Startlöchern! Also, Roland, da geht was! Bleib mal am Ball. Wir machen das schon.

73, Stefan

Your suggestion regarding Youtube video's is excellent. My interest is VLF / MF reception and as such SpectrumLab has not been my choice as as far as I know it does not feature fast playback of IQ recordings. But maybe I am wrong. Watching one of Leif, SM5BZ's Youtube video's, I found that Linrad has such a feature and I have been using it ever since. I am making Linrad overnight recordings every night from 100 - 600 kHz and this enables me to playback any channel in this range the next day. Playback takes less than 15 minutes and you can set reception parameters as you like, making a very flexible system. This approach fits in better with my interests than parking one or more receivers on a particular channel and using e.g. SpectrumLab or ARGO. Leif's video's are highly recommended and I have learned a lot from it. It takes time, but it is time better spent than running in circles trying to make complicated (to the inaugurated) software work! 73, Roelof Bakker, pa0rdt From owner-rsgb_lf_group@blacksheep.org Mon May 2 18:22:24 2016 Return-Path: X-Spam-DCC: paranoid 1181; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=0.1 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, FORGED_RCVD_HELO,HTML_MESSAGE,HTML_TINY_FONT,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u42GMNgf014652 for ; Mon, 2 May 2016 18:22:23 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1axGX4-0002ww-At for rs_out_1@blacksheep.org; Mon, 02 May 2016 17:17:14 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1axGX3-0002wn-Mn for rsgb_lf_group@blacksheep.org; Mon, 02 May 2016 17:17:13 +0100 Received: from smtpdb9.aruba.it ([62.149.158.251] helo=smtpdb7.aruba.it) by relay1.thorcom.net with esmtp (Exim 4.87) (envelope-from ) id 1axGWw-0008PV-In for rsgb_lf_group@blacksheep.org; Mon, 02 May 2016 17:17:12 +0100 Received: from ik0vve.net ([62.149.158.90]) by smtpcmd03.ad.aruba.it with bizsmtp id pUH41s00s1xJdJu01UH401; Mon, 02 May 2016 18:17:05 +0200 Date: Mon, 2 May 2016 18:17:04 +0200 Message-Id: In-Reply-To: <572619ED.1040402@posteo.de> References: =?iso-8859-1?q?=3CO6FK1F=244E758375A73045921482661B20E9AE5A=40ik0vve?= =?iso-8859-1?q?=2Enet=3E_=3CO6HQVJ=242F7891F4C3FDD2B2A991A8F465C21493?= =?iso-8859-1?q?=40ik0vve=2Enet=3E_=3C572619ED=2E1040402=40posteo=2Ede?= =?iso-8859-1?q?=3E?= MIME-Version: 1.0 X-Sensitivity: 3 From: "Max IK0VVE" To: rsgb_lf_group@blacksheep.org X-XaM3-API-Version: V3(R2) X-SenderIP: 212.66.112.179 X-HELO-Warning: Remote host 62.149.158.251 (smtpdb9.aruba.it) used invalid HELO/EHLO smtpdb7.aruba.it - verification failed X-Scan-Signature: eec106d36eb876515d296e51093c048c Subject: Re: LF: testing VLF grabber Content-Type: multipart/alternative; boundary="_=__=_XaM3_.1462205824.2A.371889.42.19411.52.42.007.1092665549" X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Scanned-By: MIMEDefang 2.56 on 10.1.3.11 Status: O X-Status: X-Keywords: X-UID: 7973 --_=__=_XaM3_.1462205824.2A.371889.42.19411.52.42.007.1092665549 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi Stefan,thanks for suggestions.=0A=0ATonight I'll suspend the grabber s= ession to implement the 1pps GPS.=0AThis was just a testing to see if I'v= e problem with web upload, pc, etc...

Hi Stefan,thanks for suggestions.

Tonight I'll suspend the grabber = session to implement the 1pps GPS.
This was just a testing to s= ee if I've problem with web upload, pc, etc... At the moment I'm using an= old notebook that gives me the possibility to run a couple of SL session= s without wasting much energy. 
Ok for filtering the recep= tion, this will improve for sure the signal quality.
Unfortunat= ely, also living in a small rural suburb, I've a lot of noise for some ye= ars now "thanks" to new neighbor (LED lights), so I'm looking to install = all system in a quieter place that can be easily approachable by a 5 ghz = LAN, may be I could get ideas from your remote station, HI.
I know that IW4DXW Riccardo and IK7SLZ Domenico are warming u= p for VLF transmission. Rick transmitted for a while yesterday night but = some capacitors problem impede a good system performance, so We are looki= ng for new C's. I'm in the center between the two OM so could be a good p= lace for RX test.
Not so many Italian HAM in VLF and LF now.

Thanks for now!

73, Max I= K0VVE

I have had a malfunction of the CAT interface between my radio and the WSPR program. It seems it has occasionally failed in the past but I've seen to tell-tale on the screen here. This evening on my return there is a "can't talk to the radio" message The frequency reported is in fact the offset from 1500 (the CAT was reporting 0.00Hz as the tuned frequency).

Hi Stefan,
thanks for suggestions.

Tonight I'll suspend the grabber session to implement the 1pps GPS.
This was just a testing to see if I've problem with web upload, pc, etc... At the moment I'm using an old notebook that gives me the possibility to run a couple of SL sessions without wasting much energy. 
Ok for filtering the reception, this will improve for sure the signal quality.
Unfortunately, also living in a small rural suburb, I've a lot of noise for some years now "thanks" to new neighbor (LED lights), so I'm looking to install all system in a quieter place that can be easily approachable by a 5 ghz LAN, may be I could get ideas from your remote station, HI.

I know that IW4DXW Riccardo and IK7SLZ Domenico are warming up for VLF transmission. Rick transmitted for a while yesterday night but some capacitors problem impede a good system performance, so We are looking for new C's. I'm in the center between the two OM so could be a good place for RX test.
Not so many Italian HAM in VLF and LF now.

Thanks for now!

OK for the second grabber, I disposed also for it as= for narrower band, band filter and NB.

Rick (IW4DXW) and Dom (IZ7SLZ) are each about 680 km far from me, the first to North and the second to south east.
Oh, that's very far. I rather expected something like 20 km.
I know Rick is transmitting in these hours.
Hmm, he doesn't tell us.

Yesterday I've chenged the RX antenna from 60 wires loop to the TX (un-tuned) antenna of 630m, I've seen signals growing all over the band.
What does that mean? An overloaded RX? With such a large antenna on the soundcard you will need a low pass filter. Simple RC chains would work well. Maybe 2x 10kOhm + 1nF.

Copied 'VLFDX'

Reference phase: constant
Eb/N0: +5.4 dB
BER: 26.8 %
Carrier: S/N: 19.77 dB in 9.8 uHz
Error map: http://abelian.org/vlf/tmp/160502a.gif

I am seeing the expected 6dB signal reduction
at the lower antenna current.

Ran LWPC for the path DK7FC to DF6NM and it predicts only 11 degree phase change between day and night. I also ran DK7FC to Todmorden for 6.47 kHz and it says 36 degrees day/night phase change. Strange, that's much the same as for 8.27 kHz. And DK7FC to DF6NM at 6.47 kHz is 30 degrees day/night. I don't know enough about LWPC to trust its numbers at these short ranges. For example does it include the ground wave component? -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Tue May 3 22:38:09 2016 Return-Path: X-Spam-DCC: paranoid 1356; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-2.2 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, FORGED_RCVD_HELO,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u43Kc6t4020019 for ; Tue, 3 May 2016 22:38:06 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1axgzw-0005Q0-Nh for rs_out_1@blacksheep.org; Tue, 03 May 2016 21:32:48 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1axgzw-0005Pr-BX for rsgb_lf_group@blacksheep.org; Tue, 03 May 2016 21:32:48 +0100 Received: from mout.web.de ([212.227.15.4]) by relay1.thorcom.net with esmtps (TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256) (Exim 4.87) (envelope-from ) id 1axgzu-0003uB-6p for rsgb_lf_group@blacksheep.org; Tue, 03 May 2016 21:32:47 +0100 Received: from mo2014.fritz.box ([217.224.221.254]) by smtp.web.de (mrweb002) with ESMTPSA (Nemesis) id 0Lechi-1bS7es1E2I-00qQrb for ; Tue, 03 May 2016 22:32:44 +0200 Date: Tue, 3 May 2016 22:32:40 +0200 From: Michael Oexner X-Priority: 3 (Normal) Message-ID: <26793257.20160503223240@web.de> To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 X-Provags-ID: V03:K0:c49sMRAwx6uiVO1tLcL7U8OwBmTl0HiL2s8VAGdaqZt8bbZ7OBX EJMFwo6uAMzqEzPvAZYbQoDAa5nKKpe5Uh/VZNkoRH7RdE9kvbwhfy2fCcsVYDVzVlEReRO R0QqHSsMEIdABuKgrYDCaC1B/F2Qql7sNuYlkIHVHyiMiCIAaym1xLKjwT5SbPaxNE/m9Hl zYMMuG94wU7kR4vomdEtw== X-UI-Out-Filterresults: notjunk:1;V01:K0:T5f1GYV/dvo=:OHNnlZI1mkCYC2oU9Hn/Es Fac9x5SYvMQzMagoyzvSKxETQHySSMqCJX6rAGId1dFeeOk/P6UR+62GNs7+JjvJpBqqHVM3v P0L8QM9GWwBB0j85VguIjQy/G/Z92efy1Eq2XLL1bJaq2OKpLIf+ZRO3AzlHKClH2RPj1YUrj RRUn+mNqZZ8UHuhihkUvZcsixRURmYwQIK+Bobd75+Q6npNdmps2IIE9TQdji5pgHpmzgquEk LfhpWjZEYe6msTVmQ0l4rZZRYal4OuyYRvbzOSm/CMAk7L2mZ8FpiV1D+8zicZsYEZyjSMp8+ 1KMyHf6KDH3YKmVMwP/35ZNjmSsUe/Qmi0UiCxpsmrxwV4TFUFBgVoxAZlgkFaaWP8oQb/J4q eftunIEICmeORAjsZCVG+x4aOzJYVlq4i5C2Tn3mgbhfjdvKUT0fiegNeHf8MxOlRoCeJN67j O8vASjG3gDD3CnlLkNh782CClMlAV9dV3JDjLWTnQt+vss9mxm6jdlysS5QKIHGQi2701qPG/ zQ/wyQsOsY6TwJkqjWrf7XfaZ9dqBqu3I3LYnuP8a60ZE39xLa/k9xweWh14EQTopuFczKwAu bpgwp7KuA+QBqDVt0CVOskCgQrjAIxQLW28UboU4Rq35erqcOGhl6V45ykilI6Jm21I8iqCRv TMCaTFvwn2QKr21w8Dm7KeMDDTixPaRx1Zm2ifjgvzrFBPo8G4dJC9gbuvi5DaMsNuc4hKD7J ftO92DN6gijurzFtGoU87kyiTLwqP8jkbla661Z8oyQqm5KWzZ76Bloh30ivDeM7Oyec/2RmY kQHdJXY X-Scan-Signature: 49f0f587e44d6711c57b8a4e950ba850 Subject: LF: 2016 edition of the ENDBH & NANDBH Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Scanned-By: MIMEDefang 2.56 on 10.1.3.11 Status: O X-Status: X-Keywords: X-UID: 7985 Hi all, A bit later than usual, but the 2016 edition of the ENDBH & NANDBH handbooks and CDs is finally available!

Hi VLF,

I have added the remaining yoghurt cups of the stacked loading coil and put 100 of 100 iron power cores into them. The resonance was now found at 6.5x kHz but i want to go to my old frequency, 6.47 kHz.

I am already on the air! The antenna current is about 150 mA but i still have to optimise things a bit.

I have extended my VLF2 grabber for the band, http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html

Also i have added a 47 uHz window to give IW4DXW and others a chance to leave a trace there on 8.27 kHz.

Maybe i will transmit some EbNaut later, but a simple carrier would be helpful for the first tests...

Hello Luis,=

 

one way to change = the range without opening meter is to use two 4/1 radio transformers:

- first transforme= r high side to the TX, and low side to one and of the meter

- second transform= er low side to the other end of the meter and high side to the antenna

Drawback: the tran= sformers will introduce some additional loss

By the way, the critical point of this idea is that the system will be mono-channel. Both sides (Rx grabber and Tx station) must have the frequency very, very close to the nominal in order to get decodes by an unattended EbNaut-Rx session. As you known, "playing" with offsets can make big differences with EbNaut. Also multi access to the channel will be a problem, but for sure not at the beginning, with few operators. My suggestion, for an initial activity, is to have a grabber, like OPDS, with a SL front-end that automatically exports the recording wave-files. The idea is to share these recording wave files with the community using DropBox or other means. So every operator, after its transmission, can attempt to decode itself by running EbNaut locally: he knowns already the parameters used and he can try to fix the offsets, without waiting for the grabber's operator job. Note that this arrangement supersedes the mono-channel and multi-access problems. If a transmission is also announced, then also other operators can download the files from these "grabbers" and make training on decoding procedures. Local running of EbNaut-rx.exe with files already created, does not requires frequency or timing accurancy at all. This really can increase interest on that mode. I think that this grabber is not so complicated to do. It will be possible to use SL recording function steered by the SL scheduler. Maybe should be better to have some modifications in Spectrum Lab in order to include, in the header of the recordered wave file, also the callsign of the Rx station. Modifications in EbNaut-Rx will be necessary to show the callsign in the decoding page or log. Thanks again Stefan for your activities on VLF. 73 all, Domenico iz7slz On 29 April 2016 at 23:43, DK7FC wrote: > Hi VLF, > > Now, i'm not sure what the marority is thinking about VLF these days.

Hello Stefan, and "EbNauters= "

I like =F0=9F=91=8D your idea of this "beacon mode= " that can be helpful to rise the activity in EbNaut.
=C2=A0
By the way, the critical point of th= is idea is that the system will be mono-channel. Both sides (Rx grabber and= Tx station) must have the frequency very, very=C2=A0 close to the nominal in order to get d= ecodes by an unattended EbNaut-Rx session. As you known, "playing"= ; with offsets can make big differences with EbNaut.
Also multi access t= o the channel will be a problem,=C2=A0 but for sure not at the beginning, with few=20 operators.

My suggestion, for an initial activity,= =C2=A0 is to have a grabber, like OPDS,=C2=A0 with a SL front-end that auto= matically exports=C2=A0 the recording wave-files. The idea is to share thes= e recording wave files with the community using=C2=A0 DropBox or other mean= s.=C2=A0 So every operator, after its transmission,=C2=A0 can attempt to de= code itself by running EbNaut locally: he knowns already the parameters use= d and he can try to fix the offsets, without waiting for the grabber's = operator job.=C2=A0 Note that this arrangement supersedes the mono-channel = and multi-access problems.

If a transmission is also announce= d, then also other operators can download the files from these "grabbe= rs" and make training on decoding procedures. Local running of EbNaut-= rx.exe with files already created, does not requires frequency or timing ac= curancy at all. This really can increase interest on that mode.

I think that this grabber=C2=A0 is not so complicated to do. It will= be possible to use SL recording function steered by the SL scheduler.
= Maybe should be better to have some modifications in Spectrum Lab in order = to=C2=A0 include, in the header of the recordered wave file, also the calls= ign of the Rx station. Modifications in EbNaut-Rx will be necessary to show= the callsign in the decoding page or log.

Thanks again S= tefan for your activities on VLF.

Hi VLF,

Now, i'm not sure what the marority is thinking about VLF these days. Many OMs are in the background. I hope it is rather interesting then annoying, that VLF stuff :-)

When comparing EbNaut with other modes, we can see that it seems to be the most effective mode, at least on LF and VLF.
On the other hand, it is complex to handle, maybe to complex for some. FFT data must be exported by SpecLab, start times must be known exactly, as well as the frequency and 'even' the message length and= the symbol length. The frequency stability must be extremely good.
But from a different point of view this makes the mode as flexible and effective as it can be. So it is no critisation at all, i just have ideas how to extend the usage so it becomes practicable for more stations, maybe also on LF/MF.

Now, for a comparison to other digital modes which allow to have a QSO (e.g. JT9) or running a beacon and a 'grabber' window (WSPR or OP32= ) there are pre-defined settings, like the start time (each even minute for WSPR) or the frequency range or the content.

What i would like to have (and maybe others too) is a special EbNaut+SpecLab+Script(s) system that runs periodically and writes and displayes the decode result in a txt file that can be displayed on a grabber site, just like the OPDS32.txt on my LF DX grabber.
That system should be easy to install for most of the operators here. It should run automatically in the background and should consume less then 20% CPU power during decoding. A decode time of 10 minutes is no problem when it runs in the background anyway.

We could discuss and define different modes for VLF:
One mode could be 'beacon'. Definition (for example): starti= ng each hour on 1 or 2 channels (selectable, 1 or 2 or 1+2) (=3D defined frequency); 30s symbols (or 10s or 60s, selectable, must be stated on the grabber page); 6 characters (for a longer callsign like IZ7SLZ)
With such a pre-definition, there's no need for an announcement, which is the main difference between EbNaut and other modes. The result, which can be even checked for plausibility (filtering nonsense-callsigns) could be displayed like the OPDS32.txt results, showing date, time, message, SNR and further relevant data. A script (written by Markus) could automatically start the decoder, read the FFT data, search for results, display them in EBN.txt and delete the FFT data file then. The FFT input size could be limited to a small value so the decode time becomes short and the file size becomes small. With 30s and 6ch this takes 280 minutes, so a beacon transmitter station could run 5 hour sequences. It's then a bit like a grabber indicating the transmitting station which QRSS mode must be choosen.

Another one could be 'QSO', with 30 or 60s symbols and 15 characters, using a single channel, i.e. a discrete frequency. A bit like JT9 but with stricter limitations.

What do you think, Markus and Paul. Could it be helpful to rise the activity in EbNaut, maybe also on LF? Would someone of you provide the scripts or maybe a special decoder edition for that task?

Hello Luis,

 

one way to change the range without opening meter is to use two 4/1 radio transformers:

- first transformer high side to the TX, and low side to one and of the meter

- second transformer low side to the other end of the meter and high side to the antenna

Drawback: the transformers will introduce some additional loss

Hello Luis,<= /p>

 

one way to change t= he range without opening meter is to use two 4/1 radio transformers:

- first transformer= high side to the TX, and low side to one and of the meter

- second transforme= r low side to the other end of the meter and high side to the antenna

Drawback: the trans= formers will introduce some additional loss

Last night the antenna current was 165 mA only because it was a bit detuned. Also the output transformer is quite loud at 6.47 kHz so i had to stop during the working day.

R, i understand. Last night the antenna current was 165 mA only because it was a bit detuned. Also the output transformer is quite loud at 6.47 kHz so i had to stop during the working day. I think the core begins to saturate at that frequency and the output voltage is even higher due to the higher total loss resistance (2 additional coils).

No decode so far but that's no surprise.  I need to find the
right settings for this frequency: calibrating the E and H
rx phase and finding the best pre-blanker filter settings.

The filter settings become more critical down here because
some mains harmonics start to appear in the pass band.

Is it possible to send a few hours of carrier?

And this is the main difference to other modes like OP32 or WSPR. In OP32 or WSPR, anyone can just start to TX without announcements and there will be displayed results without the manual decoding procudure. BTW i like that 'work', i like to convert the txt files in Markus' software and i like to tell the EbNaut decoder the symbol length and start time offset :-) This will of course be done in the future for any special experiment. Ah and i also like the SpecLab help file, just want to tell that to avoid misunderstandings ;-) Another thing that must be considerated is the psychological effect!! I am sure that one of the reasons why WSPR is so popular is the map and database, where everybody can see who is QRV, who has 'worked' whom, who has the better RX or TX station, who suffers or profits from special locations. When i left decodes at FR5ZX on MF and everyone can see it on the map, the OMs begin to think "I want that too!", it is the same when IZ7SLZ appears in the OPDS decode list of TF3HZ or VY7MAE! If you just generate a local decode that is not published for a longer time on a place where many people are watching, then the good results becomes forgotten, maybe not in the mind of the TX and RX station but propably in the mind of eventual future TX stations or RX stations. All in all it's the motivating factor. I a private mail you wrote that you think it will take 5...7 years until there is more activity on VLF. That may be right. But i think if you make such a tool available, similar to OPDS32.txt on grabber pages, this time could become shorter. What i thought basically is a script (i don't know how to do it for Windows PCs) that works similar to OPDS32. It ready exported FFT data text files and displays the results in the txt file which can be published. In contrast to OPDS32, the start time must be exactly choosen by the TX and RX station. But on VLF, where symbol lengths of a few 10 seconds are used, 0.5 second is not so critical too. But it is no problem to get the needed accuracy in timing and frequency. The frequency is no problem at all because, if a TX station has a drifting signal, there is no chance anyway. So this is the standard, 8270.1 kHz means 8270.10000 Hz, not 8270.098561 Hz + 0.1 mHz/hour (of course all measured within the observed bandwidth). So then we would need some pre-definitions, like WSPR or JT9 or even CW has too, to avoid the need for announcements. One definition would be the frequency (1 or 2 or 3 selectable channels, discrete frequencies). Another the time stamp, for example each hour or each 30 minutes, even if a transmission take 4 hours. And of course the number of characters. You will like to have 6 characters i guess :-) Ah and the symbol length, maybe defined to 30s and 100s or so. Must be discussed. And it should be possible to edit these numbers in a config file. It should be possible to tell the EbNaut decoder via a script "Use that file, look on that frequency and that symbol length and that time offset for 6 characters and write the results into your log file. Then look on that (other) frequency and do the same again". If this is done every hour, it is no big problem for the PC i think. In a last step the log file could be filtered for the decodes. If we define that it must be a callsign, like in OPDS32, we can filter out any decode that doesn't match the profile CNCC or CCNCC or CCNCCC (C=character, N=number) and so on. So, '5Q34=0' would be filtered. As you suggested, it would even be helpful to use the callsloc list from OPDS32, so the locator is already known and more information is available in the txt file on the grabber. It would be a challenge open to everybody, ready to see a surprise for both operators, on the RX and TX side :-) 73, Stefan Am 04.05.2016 12:04, schrieb Domenico IZ7SLZ: > Hello Stefan, and "EbNauters" > > I like 👍 your idea of this "beacon mode" that can be helpful to rise > the activity in EbNaut. > > By the way, the critical point of this idea is that the system will be > mono-channel.

Hello Stefan, and "EbNauters"

I like 👍 your idea of this "beacon mode" that can be helpful to rise the activity in EbNaut.
 
By the way, the critical point of this idea is that the system will be mono-channel. Both sides (Rx grabber and Tx station) must have the frequency very, very  close to the nominal in order to get decodes by an unattended EbNaut-Rx session. As you known, "playing" with offsets can make big differences with EbNaut.
Also multi access to the channel will be a problem,  but for sure not at the beginning, with few operators.

My suggestion, for an initial activity,  is to have a grabber, like OPDS,  with a SL front-end that automatically exports  the recording wave-files. The idea is to share these recording wave files with the community using  DropBox or other means.  So every operator, after its transmission,  can attempt to decode itself by running EbNaut locally: he knowns already the parameters used and he can try to fix the offsets, without waiting for the grabber's operator job.  Note that this arrangement supersedes the mono-channel and multi-access problems.

If a transmission is also announced, then also other operators can download the files from these "grabbers" and make training on decoding procedures. Local running of EbNaut-rx.exe with files already created, does not requires frequency or timing accurancy at all. This really can increase interest on that mode.

I think that this grabber  is not so complicated to do. It will be possible to use SL recording function steered by the SL scheduler.
Maybe should be better to have some modifications in Spectrum Lab in order to  include, in the header of the recordered wave file, also the callsign of the Rx station. Modifications in EbNaut-Rx will be necessary to show the callsign in the decoding page or log.

Thanks again Stefan for your activities on VLF.

Hi VLF,

Now, i'm not sure what the marority is thinking about VLF these days. Many OMs are in the background. I hope it is rather interesting then annoying, that VLF stuff :-)

When comparing EbNaut with other modes, we can see that it seems to be the most effective mode, at least on LF and VLF.
On the other hand, it is complex to handle, maybe to complex for some. FFT data must be exported by SpecLab, start times must be known exactly, as well as the frequency and 'even' the message length and the symbol length. The frequency stability must be extremely good.
But from a different point of view this makes the mode as flexible and effective as it can be. So it is no critisation at all, i just have ideas how to extend the usage so it becomes practicable for more stations, maybe also on LF/MF.

Now, for a comparison to other digital modes which allow to have a QSO (e.g. JT9) or running a beacon and a 'grabber' window (WSPR or OP32) there are pre-defined settings, like the start time (each even minute for WSPR) or the frequency range or the content.

What i would like to have (and maybe others too) is a special EbNaut+SpecLab+Script(s) system that runs periodically and writes and displayes the decode result in a txt file that can be displayed on a grabber site, just like the OPDS32.txt on my LF DX grabber.
That system should be easy to install for most of the operators here. It should run automatically in the background and should consume less then 20% CPU power during decoding. A decode time of 10 minutes is no problem when it runs in the background anyway.

We could discuss and define different modes for VLF:
One mode could be 'beacon'. Definition (for example): starting each hour on 1 or 2 channels (selectable, 1 or 2 or 1+2) (= defined frequency); 30s symbols (or 10s or 60s, selectable, must be stated on the grabber page); 6 characters (for a longer callsign like IZ7SLZ)
With such a pre-definition, there's no need for an announcement, which is the main difference between EbNaut and other modes. The result, which can be even checked for plausibility (filtering nonsense-callsigns) could be displayed like the OPDS32.txt results, showing date, time, message, SNR and further relevant data. A script (written by Markus) could automatically start the decoder, read the FFT data, search for results, display them in EBN.txt and delete the FFT data file then. The FFT input size could be limited to a small value so the decode time becomes short and the file size becomes small. With 30s and 6ch this takes 280 minutes, so a beacon transmitter station could run 5 hour sequences. It's then a bit like a grabber indicating the transmitting station which QRSS mode must be choosen.

Another one could be 'QSO', with 30 or 60s symbols and 15 characters, using a single channel, i.e. a discrete frequency. A bit like JT9 but with stricter limitations.

What do you think, Markus and Paul. Could it be helpful to rise the activity in EbNaut, maybe also on LF? Would someone of you provide the scripts or maybe a special decoder edition for that task?

one way to change t= he range without opening meter is to use two 4/1 radio transformers:

- first transformer= high side to the TX, and low side to one and of the meter

- second transforme= r low side to the other end of the meter and high side to the antenna

Drawback: the trans= formers will introduce some additional loss

The carrier was running through the night and the morning at 200 mA. I stopped at 14:45 UTC.

A second EbNaut message will start:

That is very nice. Can you show a graph showing a spectrum peak with noise and signal in a reasonable bandwidth? I'm very happy with my VLF remote grabber, have been impressed by the low man made noise levels above 5 kHz. The diurnal QRN is much lower on 6.47 relative to 8.27. I hope this can be an advantage. Yesterday i have been on the tree, completing the installation of the E-W single turn loop which is now used. > Daytime is 0.04 fT or > below and might be a bit of a struggle. Oh, such a difference. What could be the reason, propagation? What day/night ration can be found on 8.27? It would be interesting to get the information which band is 'better', when assuming a current limited TX system. On 8.27 kHz the ERP will be 2.1 dB higher then on 6.47 kHz. But maybe the phase stability and diurnal propagation (in a range below 2000km) will be better on 6.47 kHz. On the other side, the average RX system will have a higher man made noise level there. > > I don't need any more carrier.

OK, i'm looking forward to your EbNaut decodes of my two transmissions :-) With 0.14 fT there is a real chance i think. As i know you, i think you want to wait with the presentations of your decodes until you've found the best filter+blanker settings to get the best SNR possible. My next goal is of course the 58 km band, 5.17 kHz, where i have been active just 2 times ( i think) in 2010/2011. Then, i will go lower for the first time.

Stefan, all,

I do not have time to reach you that= you already run away to lower frequencies, HI.

= I passed the last nights to try to discipline my audio board with my 1pps= GPS... nothing to do, I've tried all, levels, phases, etc... I followed = the Wolf's tutorial without success. I suppose duty cycle is to low. I'm = waiting for a new GPS so I'll try with that or in the worst case with an = OCXO+GPS 10khz.
So only for test now I'm pointing to Germ= an LF station DHO. Inserted BP and NB and moved to about 100uHz the resol= ution of the grabber.

Tomorrow a little trip, no= t so far, to an Ham friend to listen if his zone is quieter than where I = live.

I'm interested to your Raspberry Pi remote= system, can we get more informations?

Thanks, 7= 3, Max IK0VVE

So maybe someone can detect a trace down there.

The message is correct. It is the first digi mode message on 6.47 kHz. -0.3 dB Eb/N0, that's quite critical, and that for 100 second symbols. Also the phase variations seem to be much higher than on 8.27. The question is, is this reproducable and/or is it related to our path only. Maybe, going 200 Hz up or down would show a significantly different behaviour?!

But at least we now have a stake in the ground at 6.47, I can probably squeeze another dB out of it after some more tweaking. Plus, it was a noisy summer night. I'll have a look now at your 6480 carrier to do some more adjustment. Continuing to try for your first message but I'm probably still 2 or 3dB short. The day/night phase change isn't a problem, interesting that it isn't less than at 8.27 kHz but it's complicated at these short ranges. Markus I hope you can get the rx away from that railway! Even if you can find a gap in the harmonics, you've still got the nearby harmonics restricting the action of the sferic blanker. -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Sat May 7 14:17:36 2016 Return-Path: X-Spam-DCC: paranoid 1117; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-2.0 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, HTML_30_40,HTML_MESSAGE,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u47CHZU2031229 for ; Sat, 7 May 2016 14:17:35 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1az15S-0004lL-Ri for rs_out_1@blacksheep.org; Sat, 07 May 2016 13:11:58 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1az15R-0004lC-Mc for rsgb_lf_group@blacksheep.org; Sat, 07 May 2016 13:11:57 +0100 Received: from smtp06.smtpout.orange.fr ([80.12.242.128] helo=smtp.smtpout.orange.fr) by relay1.thorcom.net with esmtps (TLSv1:DHE-RSA-AES256-SHA:256) (Exim 4.87) (envelope-from ) id 1az15P-0003Y1-PN for rsgb_lf_group@blacksheep.org; Sat, 07 May 2016 13:11:56 +0100 Received: from xps.home ([82.121.166.226]) by mwinf5d63 with ME id rQBt1s00N4tQSuA03QBtPJ; Sat, 07 May 2016 14:11:54 +0200 X-ME-Helo: xps.home X-ME-Date: Sat, 07 May 2016 14:11:54 +0200 X-ME-IP: 82.121.166.226 Date: Sat, 7 May 2016 14:11:53 +0200 From: Michel Brunel X-Priority: 3 (Normal) Message-ID: <1856590746.20160507141153@mterrier.net> To: rsgb_lf_group@blacksheep.org In-Reply-To: <572D1111.9030302@posteo.de> References: <40b8e5c6692149a7911fe77631ebb33b@kabelmail.de> <572BB679.2040107@posteo.de> <572BE449.5010806@abelian.org> <279E0DEFDAFA4C849152DBBA3BFEDE8C@White> <572C5E72.7010404@posteo.de> <912731037.20160506233059@mterrier.net> <572D1111.9030302@posteo.de> MIME-Version: 1.0 X-Scan-Signature: 54c274b8b0f8da777e8f702c98fe24ad Subject: Re: VLF: EbNaut transmissions on lower frequencies?, pre-tests: 6.47kHz Content-Type: multipart/alternative; boundary="----------0BD0120501B8D0293" X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Scanned-By: MIMEDefang 2.56 on 10.1.3.11 Status: O X-Status: X-Keywords: X-UID: 8021 ------------0BD0120501B8D0293 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Thanks Stefan, VLF is a step toward LF, I'm planning to be "EbNaut ready" = RX and TX for summer on 137 kHz=20 It's too early to conclude about SpectrumLab on Linux/wine.

I'm also trying to setup Paul's excellents vlfrx-tools. I just need to buil= d a proper integrator for the 1PPS  in order to feed vttime with a cor= rect pulse. (1PPS pulse witdh =3D 25 mS)

Hello Michel,&= nbsp;

That is very nice to hear, thank you for trying. Welcome back on VLF :-)
I remember you had very good results in the old days!
Currently i am running about 200 mA on 6480.00000 Hz, on request of DF6NM. = Also i know that DJ8WX is listening and others too. 
Linux/wine, does it mean you are using SpecLab on Linux? If so, does it wor= k well?
OK about EbNaut, exciting to see there are more RX stations. Maybe EA5DOM w= ill leave a signal from the other direction in some time ;-)

Hello Stefan,

Now running the 40 =C2=B5Hz test under Linux/wine ...
Antenna is a 10 meter vertical (no loop yet, too noisy at home)

Hope to be ready for EbNaut in a few days.

Hello Markus, = VLF, 

OK so i will run the next carrier on 6480 Hz for some hours this evening fo= r you and Uwe. Prepare your receivers to 47 uHz (or 63 uHz maybe).

Thanks, that was useful against the low daytime noise. I'm having fun with the H field rx, it's not working so well at 6.47 compared with 8.27. E field is doing well. At 8.27 usually H has the better S/N but not so at 6.47 I think because of the hum harmonics reducing the blanker effectiveness. The above carrier helps with diagnostics. > Start time: 07.05.2016 20:00:02 UTC > Period: 100s > Length: 19 > CRC 16 > Coding 8K19A A problem with the E-field rx here may disrupt that. Battery went flat today while I was out. Lost about 3 hours. No a disaster, EbNaut can still recover the message if the rest is received well enough. It was a very noisy night last night and geomagnetic disturbance this morning. Maybe today and tonight will make up for that. -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Sun May 8 23:57:29 2016 Return-Path: X-Spam-DCC: paranoid 1290; Body=3 Fuz1=3 Fuz2=3 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-0.7 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, RATWARE_GECKO_BUILD,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u48LvSNJ001429 for ; Sun, 8 May 2016 23:57:28 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1azWdK-0000Vr-JN for rs_out_1@blacksheep.org; Sun, 08 May 2016 22:53:02 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1azWdJ-0000Vi-RZ for rsgb_lf_group@blacksheep.org; Sun, 08 May 2016 22:53:01 +0100 Received: from mout.gmx.net ([212.227.17.22]) by relay1.thorcom.net with esmtps (TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256) (Exim 4.87) (envelope-from ) id 1azWdH-0007u0-Tg for rsgb_lf_group@blacksheep.org; Sun, 08 May 2016 22:53:00 +0100 Received: from [192.168.0.100] ([185.78.62.108]) by mail.gmx.com (mrgmx103) with ESMTPSA (Nemesis) id 0MTSmp-1b6QnO1FPb-00SSWu for ; Sun, 08 May 2016 23:52:57 +0200 To: rsgb_lf_group@blacksheep.org References: <5720901C.8070002@mbsks.franken.de> <8D36E8D13BCCF9F-1198-12704@webmail-vd002.sysops.aol.com> <5727183D.4000305@mbsks.franken.de> <572728EB.6060508@posteo.de> From: Tobias DG3LV Message-ID: Date: Sun, 8 May 2016 23:52:49 +0200 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Thunderbird/45.0 MIME-Version: 1.0 In-Reply-To: <572728EB.6060508@posteo.de> X-Provags-ID: V03:K0:ZI57T90TC4xTGAD7/NI5/NvKyNQBl3XjhGRhUXHsW0+YFrzNM10 jr4DeQKRd1+k53WYH4lOPRUq4RBtOVgxL669LiOgzMenDRL5au/2oZay3xr7K0drGJR8/LR UC7dIAzXREkRVn+HLAKY6V8WpKEMheQO8d782LTXcCyc3kf/vYj0ujhnrbkJupZNok+trrh 0eCBe9AOvh9sMh2gxr7PQ== X-UI-Out-Filterresults: notjunk:1;V01:K0:6Gs+rmEITq8=:jWBrya9H+gYrQJZ8KWn5Ii Pc1uTk7AfsL9viLi85d9JAResTjVzlug4TpsBWxSQU2Zh3EGeY6LG5DuQ2crFaUKfvPklSxl0 SOqw7u6qud+mQq2chuncwD/5q/NoL325eZu0ep584ragEqOJz41fRgjE0Gd+BwgnohkqO8+bC aaK/dnoTfpK4QKiV+4yqthhy0SzM6Kz6o3I4SI3tFps01MQU6rb8vBlYfiMVpMsA+3IAjxZPa RBSR9Mzj2/KiVmgiErIiytusVtTdf7pHdHgENblclxsJOOC3AIwUlRvBsEwSJhnnIzq3pd+nw Dezwhc+6oWZkMrk6u6fbSk/U5LdH+drlJtfQColxMROLjRyBPbX/4DDEg6md4opfCmfb0i9qE q0qrhFzffR1/6m8PQNxCvheexBdsjgxGwNegwFxKmEAhv2wNZVTnRQ5iED6eq2R+iPiHpQo+n zAyDmu0lVmuoVI6AYGHc7V4XwIQybVb34cv+AA3M+skhU+f2PmJoBZxr93ZcWa3zmb3TpUfhk uNZnTVsdIr/pouDcwq87Qd3CGpzeHMR3qJKTrYlGtvgRB+Rq2WY1JHGx25O3jq5pigUhAeOlo 1QMVXHISMiQJGwK17wDxiqKSIcFWMTewgs0B7f6E3KWTEJnYOmKCRZULvlw4egLrLG4UbLlBg TARGOJu0AXPWk9hRkmiOl2iB8TI2YPuqlqUCqisgZ/BLEDfRb+eK67KTaVG7/XfyARj5YyXcZ u29d7Rl69G2XaXymEd32aQxsxK/GCTLRUbvh8k6l3Umr8APoj09uJRge4cAfzlXcxPjQPblV5 Gl4YSrz X-Scan-Signature: 5934134de2d93cab1d5fc440b67de82f Subject: Re: LF: Re: VLF Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Scanned-By: MIMEDefang 2.56 on 10.1.3.11 Status: O X-Status: X-Keywords: X-UID: 8026 Hi Stefan ! >>> Think of DG3LV, he could be interested, too. Thank you for the invitation to those experiments. Indeed, I do have some interest for this and am reading your discussions with Paul et.al., which are at no means "annoying", but -to the contrary- is giving some inspiration for listeners to have a closer look at the field of VLF/ELF. At the time being I will not dig into that field. As Roelof and others had written, the mountains to climb to get there are very high, the expenses in terms of money and of time would be as high. To get that close to Mr. Shannon as EbNaut does is a wonderful experiment and prominently shows the advances in technology of non-military radio operators in the recent years. It is a good idea -as you have written- to show people via Video how this can be acheived. They could see what prerequisites are necessary and how complicated or easy it is to become part of it. Explanations and lectures in the style of Armin Maiwald or Harald Lesch would be very helpful and could widen the range of participants. I will be keeping an eye on it. 73 de dg3lv Tobias Am 02.05.2016 um 12:16 schrieb DK7FC: > Hallo Roland, > > Danke für deine Rückmeldung. > Ich nehme Paul auch noch ins CC. > Ich kann dich voll verstehen!

It's ok, i can understand that it's a very special operating field on the limits and you probably have many other open projects. However in one point i must disagree, it is not as difficult and expensive, not even time extensive. The limiting factor is a quite location in most cases. Actually it costs less than 50 EUR to build up a complete RX system, including preamp and reference signal source. Of course assuming that a PC is already available. 73, Stefan Am 08.05.2016 23:52, schrieb Tobias DG3LV: > Hi Stefan ! > >>>> Think of DG3LV, he could be interested, too. > > Thank you for the invitation to those experiments.

I'm asking myselfe if you are working on the decode all the time or if you are doing completely other stuff now ;-) Maybe we need more experiance with this 46km band. Maybe it is not so easy, not just 20lg(8.27/6.47) db harder. This morning the QRN is very low, a pity that i have not been on the air. I need to and will prmodify the system so i can transmit during working days, i.e. all the time. Then it could be useful to start with shorter messages during the morning hours. For example, 40s symbols and 3 characters. Or 3 characters with 200s symbols. I was wrong when saying i am output transformer limited. Yesterday i tested my VLF PA on a 1 kOhm (that's the loss resistance of the antenna, about) / 400 W resistor and watched the voltage wave form at 280 mA output current. Also watched the supply current and eventual ferrite core warming. To my surprise it is no problem to go down to 2.97 kHz, the target frequency :-) So it must have been a problem of the non-resonance of the antenna. I hope to make the system ready for 24/7 transmissions today and will announce further experiments then. 73, Stefan Am 08.05.2016 21:18, schrieb Paul Nicholson: > > > There was another carrier from 09:45...19:45 UTC today [7th] > > on 6470 Hz. > > Thanks, that was useful against the low daytime noise. > > I'm having fun with the H field rx, it's not working so > well at 6.47 compared with 8.27.

Hi Geir,

a short check of the European Perseus sites (don=C2=B4t know whethe= r you have access too) shows that you can only be heared at SM0GOJ, about 390 km ENE from you. At present your signal there is between S1 and S5 depending on QSB and your current power. He uses a BOG ant. At all other sites show nil at 476.5 kHz. Interesting result anyway!

H= ello All,

Long story short, after some initial trouble, I have now reconfigured my ATU and are pleased to report the new 60 watt beacon transmitter is on the air continously at 476.5 kHz.

After I was finished tuning up the Marconi antenna with the AA-600 analyzer, I also fine tuned it with the TX at it's lowest power, then the next higher power level, then the next and then finally at full power. The new TX was started at 12 UTC today and ha= s run since. The CW beacon cycle consists of it's callsign and maidenhead at 12 wpm CW and then four 2.5 sec. carriers at about. 60, 30, 15 and 5 watt! s, before it's all repeated again. This also means that the 2.5 watt WSPR beacon is off the air now, so for now I am TX'ing = only in CW beacon mode at 476.5 kHz.

As mentioned earlier, I will probably later set up the beacon for some weak signal modes. I can't do that right now, because I need to flash in other software first and I can only do that at home. So the plan is to let it run as now until the 17'th May, perhaps a little longer. After that the 2.5 watt WSPR beacon will be restarted and run until the next (future) test with an even more enhanced ATU.

I also wan't to say a big thank you to all of you who so kindly have given me tips and help. Needless to! say I am most grateful and thanks to you all.=C2=A0

I have prepared my transmit site so i can run permanent transmissions now! Also the antenna current meter has been re-calibrated (actually no re-adjustment was necessary).

Just in case the extreme QRN will stop in the morning, i will run a new transmission:

f = 6470.00000 Hz
Start time: 12.05.2016   00:00:02 UTC
Symbol length: 100 s
Characters: 3
CRC 16
Coding 8K19A
Duration: 11h, 33m, 20s

Antenna current: 200 mA

Maybe this one will work better. And, to be honest, in the last transmissions the antenna current fell to about 170 mA after some time because the coils sagged a bit into each other due to the heat. But now this process should have stopped and the resonance was re-adjusted. I can measure a stable 205 mA now during the time of the observation.

Yes, still working on the 19 char message.  I think I'm
about 1.3 dB short of decoding it.  Quite a challenge
because overnight 7th/8th was very noisy.

The last few nights have been quiet.  Typical!

Hi Paul, VLF,

I have prepared my transmit site so i can run permanent transmissions now! Also the antenna current meter has been re-calibrated (actually no re-adjustment was necessary).

Just in case the extreme QRN will stop in the morning, i will run a new transmission:

f =3D 6470.00000 Hz
Start time: 12.05.2016   00:00:02 UTC
Symbol length: 100 s
Characters: 3
CRC 16
Coding 8K19A
Duration: 11h, 33m, 20s

Antenna current: 200 mA

Maybe this one will work better. And, to be honest, in the last transmissions the antenna current fell to about 170 mA after some time because the coils sagged a bit into each other due to the heat. But now this process should have stopped and the resonance was re-adjusted. I can measure a stable 205 mA now during the time of the observation.

73, Stefan

Only 30.5% symbol errors were counted, which is where the Eb/N0 = +5.1 comes from. But the carrier level: 11.2 dB in 24.0 uHz corresponds to Eb/N0 = -1.1 dB. The laws of physics have changed?

Interesting to see what today's signal does - last night was low noise too. -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Fri May 13 09:44:40 2016 Return-Path: X-Spam-DCC: paranoid 1290; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-0.3 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, HTML_30_40,HTML_MESSAGE,RATWARE_GECKO_BUILD,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u4D7idZ8023811 for ; Fri, 13 May 2016 09:44:39 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1b17hj-0000pb-G2 for rs_out_1@blacksheep.org; Fri, 13 May 2016 08:40:11 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1b17hj-0000pS-3B for rsgb_lf_group@blacksheep.org; Fri, 13 May 2016 08:40:11 +0100 Received: from elvis.franken.de ([193.175.24.41]) by relay1.thorcom.net with esmtp (Exim 4.87) (envelope-from ) id 1b17hh-0002Js-Dr for rsgb_lf_group@blacksheep.org; Fri, 13 May 2016 08:40:09 +0100 Received: from uucp by elvis.franken.de with local-rmail (Exim 3.36 #1) id 1b17hg-0002zd-00 for rsgb_lf_group@blacksheep.org; Fri, 13 May 2016 09:40:08 +0200 Received: from [192.168.1.117] (r-PC.fritz.box [192.168.1.117]) by mbsks.zwiebeltuete.com (Postfix) with ESMTP id 9A49A12E1A7 for ; Fri, 13 May 2016 09:36:52 +0200 (CEST) To: rsgb_lf_group@blacksheep.org References: <40b8e5c6692149a7911fe77631ebb33b@kabelmail.de> <572BB679.2040107@posteo.de> <572BE449.5010806@abelian.org> <279E0DEFDAFA4C849152DBBA3BFEDE8C@White> <572C5E72.7010404@posteo.de> <912731037.20160506233059@mterrier.net> <572D1111.9030302@posteo.de> <572D9843.7060402@abelian.org> <572DBBD3.3020709@posteo.de> <572DC660.5050007@abelian.org> <572E4BF7.1060103@posteo.de> <572F9120.2010200@abelian.org> <5732F442.2050105@posteo.de> <5732F9E8.1090604@abelian.org> <57343F5D.5030502@posteo.de> <5734D996.8080203@abelian.org> <57351A13.3050802@posteo.de> From: Roland Bruestle Message-ID: <4619df50-a672-49c1-0c7b-5c4e09929e9e@mbsks.franken.de> Date: Fri, 13 May 2016 09:36:54 +0200 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:45.0) Gecko/20100101 Thunderbird/45.0 MIME-Version: 1.0 In-Reply-To: <57351A13.3050802@posteo.de> X-Scan-Signature: c0e6e8bcdc231effb9da2003d606d9a2 Subject: Re: VLF: EbNaut transmissions on lower frequencies?, pre-tests: 6.47kHz Content-Type: multipart/alternative; boundary="------------BB00240919C6323A4B3298D0" X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Scanned-By: MIMEDefang 2.56 on 10.1.3.11 Status: O X-Status: X-Keywords: X-UID: 8043 This is a multi-part message in MIME format. --------------BB00240919C6323A4B3298D0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit Hello Markus, Stefan, Paul, I'm back at 8170kHz and using now a class D Amplifier.

Hello Markus, Stefan, Paul,
I'm back at 8170kHz and using now a class D Amplifier. You can see me at Markus Grabber.
Amplifier :
max. power on 2 Ohm: 500W
mac. power on 4 Ohm: 250W
Power supply range. 20..48V
Switching frequency: 400kHz
IC: Texas DTA8950
IC is fan cooled
Price,  mono mode: Ebay, 50 €

My actual values:
Power supply: 30V, 3A = 90W
PA output about 80W
Antenna current: 250mA
Temperature of cooler: 37°C
Fan mostly switched off

For more power I have to increase the voltage of power supply or to lower the primary turns of the transformer.
300Ws should be not a problem.

For receiving I wont to use a min whip. I hope that the noise is not to high.

Hello Stefan,
ok, it should be 8270kHz.
I have now decreased the turns on the primary winding.
The antenna current is now 350mA, input power to the PA is 150W.
Cooler temperature remains still 37°C.
The transmission is finished since 15:00 UTC. I hope you can give me some report.

For more power I have to increase the voltage of power supply or to lower the primary turns of the transformer.
300Ws should be not a problem.

Hello Stefan,
ok, it should be 8270Hz.
I assume you mean 8270 Hz.
I have now decreased the turns on the primary winding.
As long as the transformer stays cool, you can do this. But for higher power levels it may be better to add more turns on the secondary winding. You need to watch it.
My transformer should be good for 500W with the chosen secondary windings.
The antenna current is now 350mA, input power to the PA is 150W.
Cooler temperature remains still 37°C.
The transmission is finished since 15:00 UTC. I hope you can give me some report.
Are you using a Mini Whip for receiving? I will try to receive you on you next transmissions.
As i wrote, i am using a loop into E-W direction.
I can try the 20m Loop of my 2 element Delta Loop.

Oh, i just wanted to ask if you know you signal accuracy but now i saw your signal on the DF6NM VLF grabber. It has been on the air for about one day and it looks absolutely stable. I also see a dash on the right frequency in my 47 uHz window but it disappeared during the time of low QRN. I can even see a faint trace in the 424 uHz window. I guess Paul will have even better traces.

Now what are your plans, what would you like to do there? Carriers, DFCW, EbNaut?
EbNaut. For receiving I'm not sure if my Mini Whip is good enough. Have no experience.
Ah and BTW, now your antenna C has rised since you improved the antenna. So you must have reduced the L. Do you have enough L available to go to 6470 Hz? It would be interesting to see if the daytime propagation on our short path is better there.
I will soon move to 5170 Hz, so the frequency would be clean for you :-)
I can try 6470 Hz, but I would need a lot of ferrite. The next is I have no idea how to get the output of ebnaut-tx.exe into Speclab.

73, Stefan

PS: My peak hold graph was set wrong in the 47 uHz window. It is now updated and shows the highest peak of the last 3 days.

Hello Roland,

8170kHz?
I have the EW loop connected on the tree. Don't hesitate to run a carrier during the morning hours, 4...10 UTC is a good time as you can see. With some luck i will see you in the 424 uHz window. That would be remarkable.

Hello Markus, Stefan, Paul,
I'm back at 8170kHz and using now a class D Amplifier. You can see me at Markus Grabber.
Amplifier :
max. power on 2 Ohm: 500W
mac. power on 4 Ohm: 250W
Power supply range. 20..48V
Switching frequency: 400kHz
IC: Texas DTA8950
IC is fan cooled
Price,  mono mode: Ebay, 50 €

My actual values:
Power supply: 30V, 3A = 90W
PA output about 80W
Antenna current: 250mA
Temperature of cooler: 37°C
Fan mostly switched off

For more power I have to increase the voltage of power supply or to lower the primary turns of the transformer.
300Ws should be not a problem.

For receiving I wont to use a min whip. I hope that the noise is not to high.

Hi Stefan &am= p; friends,

With new GPS the music has changed http://www.ik0vve= .net/wp-content/uploads/2016/05/gpsok.png
The old one does = not show the slope at 1pps signal.
The PC that I'm using for th= e test grabbers is too slow and I can't go at 47uHz with it: the waterfal= l never appears. Trying with newer and more powerful PC all is ok.

So far it seems that 6.47 is more variable and unpredictable than 8.27 which is opposite to what I'd expect. -- Paul Nicholson -- From owner-rsgb_lf_group@blacksheep.org Sat May 14 14:06:14 2016 Return-Path: X-Spam-DCC: paranoid 1102; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-0.7 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, RATWARE_GECKO_BUILD,SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u4EC68xA027691 for ; Sat, 14 May 2016 14:06:08 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1b1YG4-0004AH-1D for rs_out_1@blacksheep.org; Sat, 14 May 2016 13:01:24 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1b1YG3-0004A8-3A for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 13:01:23 +0100 Received: from mout01.posteo.de ([185.67.36.65]) by relay1.thorcom.net with esmtps (TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256) (Exim 4.87) (envelope-from ) id 1b1YG1-0004Hb-6f for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 13:01:21 +0100 Received: from dovecot03.posteo.de (dovecot03.posteo.de [172.16.0.13]) by mout01.posteo.de (Postfix) with ESMTPS id 4C3BE202C5 for ; Sat, 14 May 2016 14:01:17 +0200 (CEST) Received: from mail.posteo.de (localhost [127.0.0.1]) by dovecot03.posteo.de (Postfix) with ESMTPSA id 3r6QL53gsFz5vMw for ; Sat, 14 May 2016 14:01:17 +0200 (CEST) Message-ID: <5737138D.4050807@posteo.de> Date: Sat, 14 May 2016 14:01:17 +0200 From: DK7FC User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; de; rv:1.9.1.8) Gecko/20100227 Thunderbird/3.0.3 MIME-Version: 1.0 To: "rsgb_lf_group@blacksheep.org" X-Scan-Signature: 6ffbd2c9950b634d6cc91f9565b01a8b Subject: LF: A transductor instead of a traditional variometer on VLF/LF/MF?

Will this work? See: https://de.wikipedia.org/wiki/Transduktor_%28Elektrotechnik%29 https://en.wikipedia.org/wiki/Magnetic_amplifier On LF/MF and VLF many of us are using typical variometers for manual or automatic resonance correction of the transmit system. Due to the multi-layer VLF TX coil with a forced air flow in the center it is not easy (or not possible) to put an additional rotatable coil in the center to adjust the resonance frequency within a small range. So i need another solution. One solution could be to accept the non-resonance and run a higher voltage on the output transformer to keep the antenna current constant. But this will cause losses on the linear working PA and works only in a very limited range, due to the Q of the system. So it would be better to have a chance to steer the resonance anyway! But how? Now, what about a transductor? A ferrite core inside the main field of the coil. It must have a winding and a variable DC current from an external power supply. The DC current can saturate the core and change its effective r for the external AC magnetic field. If this works, then it is a non-mechanical solution! No motor, no axis, no end switches, no mechanical self oscillation, no broken RF litz wire on the rotating elements, fast changing of the resonance frequency. Has someone tried that on LF before? 73, Stefan PS: I will start to try that on VLF, IMMEDIATELY! :-) From owner-rsgb_lf_group@blacksheep.org Sat May 14 14:30:37 2016 Return-Path: X-Spam-DCC: paranoid 1102; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-2.4 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u4ECUaqB027771 for ; Sat, 14 May 2016 14:30:36 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1b1Yes-0004IS-VC for rs_out_1@blacksheep.org; Sat, 14 May 2016 13:27:02 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1b1Yes-0004IJ-Jz for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 13:27:02 +0100 Received: from lb2-smtp-cloud3.xs4all.net ([194.109.24.26]) by relay1.thorcom.net with esmtps (TLSv1:DHE-RSA-AES256-SHA:256) (Exim 4.87) (envelope-from ) id 1b1Yeq-0004To-Eg for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 13:27:01 +0100 Received: from [192.168.178.20] ([83.162.220.82]) by smtp-cloud3.xs4all.net with ESMTP id uCSx1s0091nG4D701CSyjY; Sat, 14 May 2016 14:26:59 +0200 From: "Roelof Bakker" To: DK7FC , rsgb_lf_group@blacksheep.org Date: Sat, 14 May 2016 14:26:57 +0200 MIME-Version: 1.0 Message-ID: <57371991.28985.2A7CAE@roelof.ndb.demon.nl> In-reply-to: <5737138D.4050807@posteo.de> References: <5737138D.4050807@posteo.de> X-mailer: Pegasus Mail for Windows (4.70) Content-description: Mail message body X-Scan-Signature: aee9e5eeb35c86f052d502ac97832558 Subject: Re: LF: A transductor instead of a traditional variometer on VLF/LF/MF?

Maybe it would be useful to run a beacon, periodically the same message in shorter symbols, maybe 40s. A single character would be already fine, like 'R'. This would take 3:33:20 to be sent. I could do this each 4 hours. Or i can send a simple carrier for a few days. However i want to build a circuit which keeps the antenna current constant, even during rain, so the ERP stays constant! 73, Stefan Am 14.05.2016 12:59, schrieb Paul Nicholson: > > Stefan wrote: > > > f = 6470.00000 Hz > > Start time: 13.05.2016 00:00:02 UTC > > Symbol length: 100 s > > Characters: 6 > > I haven't been able to decode this one.

Hi all, During thinking about a solution for a automatic variometer for my VLF coil i got the idea of using a transductor instead. Will this work? See: https://de.wikipedia.org/wiki/Transduktor_%28Elektrotechnik%29 https://en.wikipedia.org/wiki/Magnetic_amplifier On LF/MF and VLF many of us are using typical variometers for manual or automatic resonance correction of the transmit system. Due to the multi-layer VLF TX coil with a forced air flow in the center it is not easy (or not possible) to put an additional rotatable coil in the center to adjust the resonance frequency within a small range. So i need another solution. One solution could be to accept the non-resonance and run a higher voltage on the output transformer to keep the antenna current constant. But this will cause losses on the linear working PA and works only in a very limited range, due to the Q of the system. So it would be better to have a chance to steer the resonance anyway! But how? Now, what about a transductor? A ferrite core inside the main field of the coil. It must have a winding and a variable DC current from an external power supply. The DC current can saturate the core and change its effective r for the external AC magnetic field. If this works, then it is a non-mechanical solution! No motor, no axis, no end switches, no mechanical self oscillation, no broken RF litz wire on the rotating elements, fast changing of the resonance frequency. Has someone tried that on LF before? 73, Stefan PS: I will start to try that on VLF, IMMEDIATELY! :-) From owner-rsgb_lf_group@blacksheep.org Sat May 14 21:20:20 2016 Return-Path: X-Spam-DCC: paranoid 1233; Body=2 Fuz1=2 Fuz2=2 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on lipkowski.org X-Spam-Level: X-Spam-Status: No, score=-2.4 required=5.0 tests=BAYES_00,DNS_FROM_AHBL_RHSBL, SPF_PASS autolearn=no version=3.1.3 Received: from post.thorcom.com (post.thorcom.com [195.171.43.25]) by paranoid.lipkowski.org (8.13.7/8.13.7) with ESMTP id u4EJKJM9028420 for ; Sat, 14 May 2016 21:20:19 +0200 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1b1f3J-0005jN-L6 for rs_out_1@blacksheep.org; Sat, 14 May 2016 20:16:41 +0100 Received: from [195.171.43.32] (helo=relay1.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1b1f3J-0005jE-CD for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 20:16:41 +0100 Received: from mail-oi0-x233.google.com ([2607:f8b0:4003:c06::233]) by relay1.thorcom.net with esmtps (TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256) (Exim 4.87) (envelope-from ) id 1b1f3H-0007M3-3i for rsgb_lf_group@blacksheep.org; Sat, 14 May 2016 20:16:40 +0100 Received: by mail-oi0-x233.google.com with SMTP id x201so217407146oif.3 for ; Sat, 14 May 2016 12:16:38 -0700 (PDT) X-DKIM-Result: Domain=gmail.com Result=Good and Known Domain DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to; bh=Q6DlCaZOtlcmDPARS/R5zmbOcQEb3KR5hZFrXvvXF9Y=; b=ft8sI+qYsf3SMCT7hUfYgd9sgnAqO7bcHQSPBFshaM6CtLsE0Rd2ons/ckfnltH8VN I/T22uubBaWSubxdzRf3AoFvWFO+150Jwkbj+VRtWipzB6s0JTJvbH3Bk3mBuoQpwPkD wlGG1efbr3kjKigPYCjtz+Iv8+Yt0alZbZuFx0elR7hCUtK0NYXfynLPWWESTntoPUTy rGYyZ9YEfnoMqJCtJZOe3+WgkqUId6e7X4C0tjkGzzepLDYxpZ7r1w5Pau4hTeY8VbXd NVNaHHiv+9RvPbZBQuBJr1o/JRv5skFTPjV/hwDzSfk9e8YJIKKGCxjSSN0tpF7yBeLB Q9CA== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20130820; h=x-gm-message-state:mime-version:in-reply-to:references:date :message-id:subject:from:to; bh=Q6DlCaZOtlcmDPARS/R5zmbOcQEb3KR5hZFrXvvXF9Y=; b=P8bXw8ji+M89ku/kIR1NMcgq8Ot1703gxEcY7Nutla0yEGZXTA+ZQFwiARL4lI4MQA v8p14232lTsmX8ItBkglWj03T9GN3yfwXxRpymy+Re82sFThxPa3VGGkT30jBq3b2vyp xAw1TCsQvANjxBqp3c9cEDcRVTF7mmGUUoOBuZGNqgp4EE3HLb+qBkNK+AHZSfPA5gjp BbOIYhHW708x77dktT61lWNI7B38ymByEhssmlj0aiQLfNbW0fRLvdvrViHtq16vieZW yJwKFxtBrJFHrMqhp5dCgkU3E36bGNlYdd4rPKK6TLaQKkOAgwaRLiVEO5x5Z1dBs3oE fHdw== X-Gm-Message-State: AOPr4FUn6+/qbhaXQEduMk/qebPdbGaWGVs8p/OgjYH83yFM0Yo5Jk1BWCydbuxvSiSDGsY5CPMtIiz61S9o/A== MIME-Version: 1.0 X-Received: by 10.202.74.10 with SMTP id x10mr11059928oia.157.1463253397064; Sat, 14 May 2016 12:16:37 -0700 (PDT) Received: by 10.202.74.146 with HTTP; Sat, 14 May 2016 12:16:36 -0700 (PDT) In-Reply-To: <1771641848.20160514171621@chriswilson.tv> References: <5737138D.4050807@posteo.de> <245E116B-93B7-4A7D-AD24-FA4B8A8898BA@hurontel.on.ca> <1771641848.20160514171621@chriswilson.tv> Date: Sat, 14 May 2016 15:16:36 -0400 Message-ID: From: Warren Ziegler To: rsgb_lf_group X-Scan-Signature: 1708620d3ce65bee0beaaede7929769a Subject: Re: Re[2]: LF: A transductor instead of a traditional variometer on VLF/LF/MF?

I'm interested to= your Raspberry Pi remote system, can we get=0Amore informations?
=0A=
=0A=0AWow, of course that is a large project and i c= ould write for hours. But=0Aa rough overview should be no problem:
=0A= -The Raspi 2B is used
=0A-I'm using a 2.4 GHz link, with this yagi=0A<= a class=3D"moz-txt-link-freetext" href=3D"http://www.brennpunkt-srl.de/es= hop/product_info.php?products_id=3D188" _djrealurl=3D"http://www.brennpun= kt-srl.de/eshop/product_info.php?products_id=3D188">http://www.brennpunkt= -srl.de/eshop/product_info.php?products_id=3D188=0Aover a distance of= 3.5 km in combination with USB WLAN Sticks (ALFA=0AAWUS036NEH running in= 'g' mode) connected to the Raspi.
=0A-Two stereo USB soundcards are c= onnected to the Raspi, one for MF, the=0Aother for VLF. The samplerate is= 48 kS/s.
=0A-The radio signals of MF are converted to a range of the = soundcard=0A(0...24 kHz), VLF comes in directly.
=0A-Darkice and Iceca= st2 software is running as a web radio, vorbis stereo=0Astream. Each ster= eo stream needs 20% CPU power, about.
=0A-For VLF, i'm using the right= channel to transfer 1 pps + NMEA signals=0Afrom a cheap GPS module (13 =E2= =82=AC) which consumes just 40 mA at 3.3V. This=0Aallows to get an ultra = stable signal which is necessary for the 47 uHz=0Awindow.
=0A-On the o= ther end, SpecLab is playing the stream from it's IP adress,=0Agenerates = the first spectrogram ('wideband' on the top of the page=0Ahttp://www.iup.uni-heidelberg.de/s= chaefer_vlf/DK7FC_VLF_Grabber2.html )=0Aand feeds the audio signal to= VAC1. All other SL instances take the=0Aaudio signal from VAC1 then, so = the stream has just one client.
=0A-There is a battery voltage and cur= rent monitoring so i can all the=0Atime monitor the energy situation on t= he tree. The curves are displayed=0Aat=0Ahttp://www.iup.uni-heidelberg.de/schae= fer_vlf/DK7FC_remote_Grabber_tech.html=0A(I nned to cut some branches= because the sun is now shining from a=0Ahigher angle, so there is some s= hadow on the solar modules in the=0Aafternoon. But i don't want to cut th= em :-) In winter it is no=0Aproblem...)
=0A-There are additional circu= its for protecting the batteries from deep=0Adischarges and there is a ho= memade accu charger that has a temperature=0Aregulated cutoff voltage.=0A-Currently 2 solar modules, 50Wp each, are used. And 3 lead gel accus= =0A12V/18Ah.
=0A- So far i prefer loop antennas for MF and VLF. Two or= thogonal loops=0Afor each band, allowing RDF spectrograms. MF is running = at=0Ahtt= p://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_remote_RDF_Grabber.html<= /a>=0A, VLF is not so easy in RDF because the second channel is occupied = by=0Apps+NMEA. But there must be a solution!
=0A- In previous versions= of the system i used a bistabile relay to switch=0Aantennas remotely. Th= at worked very well.
=0A-The power consumption of the system is about = 3W now since two=0Asoundcards + the GPS module + 40% CPU power is = running permanently.
=0A--------
=0A
=0ADon't know if you alread= y started to play with the Raspi or if you are=0Askilled in Linux. I spen= t dozens of hours to get it running as it is=0Anow. But there were great = success moments many times. And i find the=0Asystem availability is quite= good, better then expected in the=0Abeginning.
=0AI don't want to mis= s the project a single day :-)
