Im not using the txco and temps in the KL1x have been anything from 45F to 100F, as our air conditioning failed for about a week. I didnt see much change in freq stability, certainly useable at dot 60. The noise blanker is OK, but nothing beats the ts870 on that score. The only mods I would like to do is to be able to turn off the AGC, and extend the frequency range below 130Khz. If anyone has the extended rx mod Id like to hear from you. Ill get into the agc mod this week sometime. The above offered in case one comes begging. It will be my receiver of choice for Fiji and HF TX for X band will be a 706MK1.

I did do some modifications as described by Jim, M0BMU: -I took out C23, 470nF -Inductor L4 (was 11 turns on a T94-2 core) changed to about 28turns 1.25mm wire on a T106-26 core. This is a white-yellow core often found in computer powersupplies. -C22 and C24 (was 10nF each) were replaced by a serie combination of an 4700pF C and 5 Ohm/10 Watt resistor (2 x 10 Ohm/5W in parallel) The output transformer is 8 turns 1.5mm wire bifilair as primairy coil, and the secundary ouput coil is wound over it consisting of 25 turns 1mm wire, from which 5 turns are actually not on top of the primairy....... I didn't write down the exact value of the coil but it was somewhere in the 400-500uH region. TEST RESULTS on 50 Volt...... FET: 2 times IRFP260N Voltage measured after the current measure resistors (so at the point L4/C25-26) was 50.1Volt at key down. Measured draincurrent: 11.6A DC-input: 580 Watt. Measured output: 560Watt at 50 Ohm! Efficiency: 96 procent!! The only things that gets hot are the current measurement resistors........... Also some heat created in the 4700pF/5 Ohm circuit. and off course my 500Watt dummyload, which doesn't like so much power........ Meanwhile I put a fan on the current resistors (R25, R26) to keep them cool......... I also found another error in the schematic diagram: R11 and R34 (was 12k) changed to 560Ohm-820Ohm. Once again thanks to all who helped me with usefull information. Next step will be working on loading coils and so on, while testing the transmitter on long duration transmissions. Need to put some extra cooling on my already forced air cooled dummy load.......... 73, Dick, pa4vhf From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 27207 invoked from network); 2 Jun 2004 04:22:22 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore04.plus.net with SMTP; 2 Jun 2004 04:22:22 -0000 Received: (qmail 13236 invoked from network); 2 Jun 2004 04:22:22 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 2 Jun 2004 04:22:21 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1BVNGf-0003DL-3L for dave@picks.force9.co.uk; Wed, 02 Jun 2004 04:22:21 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BVNFQ-0005ay-5s for rs_out_1@blacksheep.org; Wed, 02 Jun 2004 05:21:04 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BVNFP-0005ap-Oc for rsgb_lf_group@blacksheep.org; Wed, 02 Jun 2004 05:21:03 +0100 Received: from bilbo.otenet.gr ([195.170.0.13]) by relay.salmark.net with esmtp (Exim 4.24) id 1BVTnw-0007Rn-25 for rsgb_lf_group@blacksheep.org; Wed, 02 Jun 2004 12:21:08 +0100 X-Fake-Domain: otenet.gr Received: from otenet.gr (myti530-a034.otenet.gr [212.205.251.162]) by bilbo.otenet.gr (8.12.11/8.12.11) with ESMTP id i524KuDF019808 for ; Wed, 2 Jun 2004 07:20:56 +0300 Message-ID: <40BD55FE.DB84F771@otenet.gr> Date: Wed, 02 Jun 2004 07:22:22 +0300 From: Alex Deligiannis X-Mailer: Mozilla 4.75 [en] (Windows NT 5.0; U) X-Accept-Language: en,el MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org References: X-MIME-Autoconverted: from 8bit to quoted-printable by bilbo.otenet.gr id i524KuDF019808 X-Spam-Score: 0.2 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1,TW_TX=0.077 Subject: Re: LF: receivers frg100 - another one to add to the list Content-Type: text/plain; charset=iso-8859-7; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 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-PN-SPAMFiltered: yes X-Spam-Rating: 1 Press and hold AM and SSB keys then Power ON.

It's time to put the Radcom LF column together and, to be frank, things are a bit quiet. I'd like to feature some news from the "part 5" guys, who's on? what's been achieved? etc. Also any local news from around the world that I may have missed out on. Pictures are welcome too, and short technical items would be nice. All by the middle of next week. I don't ask for much do I? ;-) Thanks in advance!

There is a free program (sort of home grown) on my web site (ACN.EXE) which is about 20 years old now but still works well. It has quite good explanetory help facility and is downloaded from the "Useful Software ??" page on my site. This does work in a DOS window in 95 and 98, but I havent tried it in anything higher (I am too mean !!) no fancy graphics other than the plots and use the ALT+PrntScr for capturing the plots.

Geomagnetic activity is low and the Kp index has been "quiet" for several days now. The Dst index is moving back into positive values which should suggest low night-time absorption. (maybe good 80m and Top-Band conditions as well !!). The real-time plot of DCF39 from Steve W3EEE looks rather unauspicious, but remember that, at this time of the year, there is almost no darkness on the path, just about an hour of "twilight". If conditions continue in this way the ionosphere will be in about its most helpfull state for Laurenece's tests. Of course this needs to be balanced against the much higher static levels at this time of year (at least in the Northern Hemisphere) On daytime propagation the picture may not be so good. The background X-ray flux has fallen to A-Class and with little geomagnetic activity the daytime skywave may not be so good. Thus expect poorer signals from distances in excess of about 600 to 1000kms in daylight. For those in Europe who want to know where the lightning storms are concentrated I can recommend http://129.13.102.67/pics/Rsfloc.gif Brian and I have consulted this site regularly for a year or so now. It can also be useful to give an early warning for those with big wires up, to help protect your receiver front ends!!. Good journey Laurence, and dont go around tripping over the wild-life !!

If you're interested, a more detailed look at storms in Poland: http://www.imgw.pl/wl/internet/burza/burza.html It is always fun to refresh the page and see local lightnings to appear on the map within a few seconds :) The map legend should be obvious, the only thing that might need translating are the (- ) and (+) sign, which mean whether the lightning voltage is cloud-earth negative or positive (the latter said to be more dangerous). Recently, there is a little problem with the map: cities are ca. 30km south-west from the proper position. 73!

Hi all,
 
I've been experimenting with high stability crystal oscillators for methods of fine tuning by external electronic means.  Varicap diodes are nonlinear for voltage and temperature, so I was wanting to use some other way.  Crystal oscillators usually have coarse adjustment with an NPO trimmer capacitor, so fine tuning would be acceptable even if it was less than 1 ppm in adjustment range (sufficient to correct for ageing over a fairly long period).
 
What I came up with is variation of emitter load resistance in a Colpitts crystal oscillator.  20% or so of change in emitter resistance gives smooth control of fractional ppm change in oscillator frequency.  I have been using a fixed resistor to the emitter that is ten times the installed emitter resistor, and then a pot (rheostat) to ground also of ten times the emitter resistor.  This arrangement gave 0.4 ppm range for fine tuning with the home brew 10 MHz oven oscillator being tested.  There are minor effects with thermal equilibrium when emitter current changes, so if a precise setting is needed then more than one tweaks is needed, but it is still quite a convenient way of carrying out fine tuning with a panel mounted control.  The lead can be bypassed at the oscillator so the control is "cold" at RF.  Also the control can be a floating with earth return to the oscillator circuit to minimise a ground loop influencing the oscillator.  Probably a wirewound is the best choice for the type of pot.
 
Some types of oven crystal oscillators on the surplus market do not cater for fine tuning by electronic means (only have screwdriver access to a trimmer capacitor).  If the oscillator housing can be opened up is is fairly easy to implement a "delta emitter" wire for fine tuning.  Sometimes it is frustrating to adjust the capacitor as the only means of making a precise setting, as there is inevitable backlash effects, whereas the "delta emitter" method gives smooth fractional ppm adjustment (with due regard for temporary thermal equilibrium).

So the message sent on Sunday July 4th will include information about the result. We keep our fingers crossed! The Radio Station will be open to visitors 10:00-16:00 Swedish time. The number of visitors has increased noticeably during the last years, from 300 to 500 and last year to almost 800. The weather has been extremely good, so far. We have had some problems with the keying of the transmitter last years and hope it will be better now. "Dots" has been missing quite often (not the operators fault!!). The amateurs will operate a transmitter with the call "SA6Q" on 20 meter band during the day: 14.035 MHz CW 14.215 MHz SSB QSL for both "SAQ" and "SA6Q" via: E-mail: info@alexander.n.se Fax: +46-340-674195 Mail: Alexander - Grimeton Veteranradios Vaenner, Radiostationen, Grimeton 72, SE-430 16 ROLFSTORP, SWEDEN or via SM-bureau.

The following subject may have been discussed on the reflector before but I can't remember it.

Class D and E final amplifiers have high efficiency because they produce square waves.  When the voltage between source and  drain of the FETs is high, current is zero; when current flows voltage is almost zero.
But what happens if the transmitter is followed by a low pass filter with a shunt capacitor at the input, as is often the case?
Every cycle the charge in the capacitor must be reversed and with a current of finite value that takes some time. During that time current flows in the conducting transistor whilst voltage over it is not small. So one can expect dissipation in the transistor to increase and efficiency to decrease. 

Looking at it in the frequency domain one could say that the shunt capacitor causes the square wave to start becoming a sine wave.

If the current into or out of the capacitor is so high that charge reversal takes negligible time, so the square wave is preserved, then output resistance of the transmitter is obviously so small it almost puts a short circuit over the capacitor. In that case the capacitor does nearly nothing and could just as well be deleted... 

The problem does not arise when the LP-filter starts with a series inductor. The sudden cut-off of current would result in  a very high kick-back voltage at the drain of a single-ended amplifier, almost certain killing the transistor.
But in a push pull  amplifier this is prevented by the other transistor that starts to conduct at the same moment.
Provided of course coupling between the two halves of the primary winding is very tight.

So it seems to me that class D and E amplifiers should preferably be followed by a low pass filter with a series inductor at the transmitter side.
 
Please correct me if my conclusion is not valid.

An interesting question is whether a low pass filter is really necessary when the transmitter feeds the aerial via a series tuning coil.
Harry Grimbergen, PA0LQ, has given this some thought and he says the following (my translation).
Quote:
Not unusual is an aerial capacitance of about 300 pF and a total loss resistance in coil, aerial and earth of some 40 ohms  At 136 kHz this results in a Q of about 100 for the aerial system. At the third harmonic  this produces an extra attenuation of about 280 times, or 49 dB.  The third harmonic of a square wave is 9.5 dB weaker than the basic frequency. On the other hand radiation resistance increases with frequency squared; 9 dB for d3.
Nevertheless harmonics will be suppressed almost 50 dB.

About 16% of the power in a square wave is in the harmonics and this power is reflected back into the final amplifier.
But it is not converted into heat. The DC input is decreased by this 16% as compared to the situation where the amplifier is loaded by a resistive load of 40 ohms for the above case.  I have been able to show this also using simulation by MICROCAP.
Unquote.

A problem in  The Netherlands would be that the radio inspector does not measure harmonics as field strength but as power in the output of the transmitter (or LP-filter, when present). So selectivity of the aerial system does not help.

Any comments will be very welcome.

Dick PA0SE and others,
 
An interesting contribution.  My pushpull bipolar QRO PA can run to near squarewave performance, and I have successfully used an inductor input low pass filter for many years.  The low pass filter uses three large potcore inductors and HV polystyrene capacitors.  Texts on Class D and E do mention resonant circuits, and most of the commercial applications are in narrow bands, so tuning is a reasonable way to implement Class D/E for those users.  At LF I believe a hard driven final can simply be followed by a low pass filter and still deliver very high efficiency (certainly a lot better than Class C).  In New Zealand our band is about to be expanded to become 130 - 190 kHz, which is a relatively wide band, and not worth having tuning that needs revisiting for significant frequency change.  A broadband PA with a selection in low pass filtering is my preference.  For use only in the 136 kHz band, only one low pass filter is needed.
 
My preference for an inductor input filter came from reading (I hope my recollection is right) a Motorola article on stability of HF solid state power amplifiers, and the preference was for an inductor input filter.  I merely scaled the filter values to LF and found they worked well.  Possibly the instability bogey is not applicable to LF but I was aware that inrush current would be different if a capacitor input filter was used.  However, there are polystyrene capacitors from collector to ground so on the PA side of the output transformer there are "shunt capacitors" and these certainly reduce the "high frequency nurgles" as seen on a scope probe. 
 
I have not tried "snubber" series RC networks but I have seen commerial high power switchmode inverters that use that, and the resistors are surface mount with good power rating.  Some of that 16% "harmonic power" gets absorbed in the interests of controlling spike limits.
 
Power devices (bipolar of MOSFET) can have slower turn-off than turn-on, and I suspect this has a large impact on transients in a pushpull power amplifier.
 
Regarding suppression of harmonics, and potential radiation, the efficiency of amateur (electrically small) antennas rises significantly (more than linear) with increasing frequency.  So merely a loading coil or "net antenna Q" is only part of the consideration of radiation of harmonics.  The insertion loss of a low pass filter can be kept fairly low and I think it is best to include it in a transmitter design, especially a hard driven "squarewave" machine.

Hello Dick.
 
A brief response is that all the inductor input LPF circuits I have tried have either casused instability or fatal (for the FETS) voltages at the PA.
 
I did try your idea of no LPF in the early days of 73kHz,  and managed to get a very nice 577 report from an amateur 2 miles away on 20m.

There are two major kinds of class D, "voltage switching" / "constant voltage" and "current switching" / "constant current". G3YXM's 1kW transmitter is a good example of current switching class D design. The DC power enters the center tap of the output transformer through a large DC feeding choke which keeps the DC input current fairly constant over the entire RF cycle while the FETs take the current in an alternating fashion. The current through each FET is ideally a square wave while the voltage across the (open) FETs is a half sine period. This kind of amplifier *should* work into a parallel resonant circuit or at least a shunt-C-input lowpass filter. A common problem with this kind of amplifier is high voltage spikes that occurs when there is a "drive gap" (when both FETs are off). Snubber networks comes to mind... Full bridge (like the Decca) and half bridge (totem-pole) amplifiers are of the voltage switching kind and they work in "the opposite way". The voltage across the FETs (or whatever active devices) is a square wave while the current is sinusoidal. These amplifiers should drive the load through a series resonant circuit. With enough loaded Q in the series tank, usually 5 to 10, the load current is an almost perfect sine wave. The harmonics exists only as voltage across the transistors, only fundamental current is drawn out of the circuit. A properly designed amplifier of this kind has much less problems with overvoltage spikes since the maximum transistor voltage is confined within the supply rails. However, under ideal conditions, the FETs will switch at the zero crossings but if the load is reactive, or if the series circuit is out of tune, the voltage/current phase shift will increase switching losses. Also, the transistors will have to conduct "backwards" during a part of their ON period. MOSFETs may survive this thanks to their inherent "backward diodes" (slow! lossy!) but bipolars can quickly enter class Z (flash & bang!) if no external diodes are there to catch the backward current... :-) Andy G4JNT has written an excellent article about his 700W class D amplifier. The elegant Decca overcurrent protection is also described in this article. The article is available in PDF format on this page: http://www.nutstreet.net/xfx/smt/ Class E is very different from class D. Even though the drive is a "hard square", neither the transistor voltage nor current is a squarewave. Like class D, class E approaches 100% efficiency but, as opposed to D, class E requires quite a big capacitor across the transistor which minimises problems with high voltage spikes. Tuning is easy, simply adjust the shunt C and the series tank (either C or L) for a proper drain waveform. In my opinion, class E is the simplest and most elegant amplifier. The main drawback is that the "transistor utilisation factor" is less than for class D i.e. the same transistor would be able to give more power in class D. In class E, the peak transistor voltage is 3.5 - 4 times supply voltage and Pout is only 0.55 * Vsupp^2 / RL (approx.). If the presence of even harmonics is a problem (due to assymetrical drain waveform), it is possible to make a push-pull class E amplifier by building two identical single ended class E amplifiers, feed them 180 degree drive, and let them share a common series resonant tank and output transformer. Thanks to the series tank, the amplifier halves will never "know" that they are operating in push-pull since they both "see" a nice sinusoidal load current. Nathan Sokal WA1HQC has written a very good article about class E design. The article sokal.zip (zipped PDF) can be found on this page: http://mywebpages.comcast.net/tonne/classe.html > A problem in The Netherlands would be that the radio inspector does not > measure harmonics as field strength but as power in the output of the > transmitter (or LP-filter, when present). So selectivity of the aerial > system does not help. Maybe you could get away with a small class E amplifier. The voltage waveform on the transistor is not too far from sinusoidal. The series circuit required in class E can consist of the aerial system itself since there is no upper limit on loaded Q in the design equations. It may be tempting to connect the loading coil + antenna directly to the midpoint of a (voltage switching) class D totem-pole, but, because of nanosecond switching speed, the wire running from the amplifier to the loading coil will radiate a lot of harmonics! All the way up to VHF...

To All from PA0SE

The following subject may have been discussed on the reflector before but I can't remember it.

Class D and E final amplifiers have high efficiency because they produce square waves.  When the voltage between source and  drain of the FETs is high, current is zero; when current flows voltage is almost zero…

 

Dear Dick, LF Group,

 

The first thing is that class E refers to a very specific circuit configuration – see Alan G3NYK’s web pages at http://www.alan.melia.btinternet.co.uk/classepa.htm for a discussion of the concept.

 

The basic Class D amplifier configuration comes in two flavours; current-fed and voltage-fed. The voltage fed type drives a load resistor with a square-wave voltage, through a series-tuned tank circuit (ideally with infinite loaded Q), resulting in a sinusoidal current in the load. The current-fed type drives a load resistor shunted with a parallel tuned tank circuit (again, ideally with infinite loaded Q) with a square wave current, resulting in a sinusoidal voltage across the load. In both cases, the switching devices produce a square wave by alternately reversing the direction of the DC supply voltage or current at the desired output frequency. The voltage-fed type uses a conventional DC supply, decoupled to ground in the normal way with low impedance capacitors. A constant-current supply is not a convenient thing to produce, so in practice the current-fed type uses a conventional low impedance DC supply with a high-impedance series choke, which is a satisfactory approximation.

 

As Dick points out, one could not apply a square-wave voltage to a tank circuit with a shunt capacitor without having huge (theoretically infinite for ideal components) peak currents and power losses, as you tried to charge and discharge the capacitor instantaneously (I = C.dv/dt). Likewise, if you tried to apply a square-wave current to a series-tuned tank circuit, you would have huge voltage spikes from trying to reverse the tank inductor current instantaneously (V=L.di/dt), with similar disastrous results. So one cannot pick and choose – a voltage switching circuit must drive a load with series inductance, to keep the current to finite levels, whilst the current switching version must have shunt capacitance to avoid the voltage spikes.

 

Note that the function of the resonant tank circuit is NOT primarily to “filter out harmonics”, but to act as an energy storage “flywheel”, which allows the conversion of the square wave drive into a sinusoidal output without loss of power. It also achieves desirable switching conditions for the power transistors – in the voltage fed case, the load current is zero when the voltage reversal occurs, whilst with the current fed circuit, the voltage across the load is zero when current switching occurs. This means that, even with fairly slow switching of the transistors, transient power dissipation is low.

 

The “Decca” circuit is a clear example of a voltage-fed class D amplifier with a series L and C tank circuit. But with the push-pull designs typified by the G3YXM and G0MRF circuits, things are not so clear. For a start, neither has a resonant tank circuit as such. However, the output low pass filter is “Quasi-parallel-resonant”, in that it has resistive impedance at the output frequency (or almost so in the G0MRF case), and a capacitive impedance at higher frequencies, so it acts in a somewhat similar way to a very low Q parallel tuned tank circuit. This suggests a current-fed configuration, and indeed the ‘YXM design has the DC supply fed to the PA transformer primary via a choke, as one would expect. However, the ‘MRF has the transformer centre tap decoupled to ground via a (fairly) low impedance capacitor. So at first sight, it would appear that each time switching occurs, one MOSFET or the other must try to transfer charge instantaneously from this capacitor to the filter input capacitor through the transformer, resulting in a large transient current spike. However, in reality, life is more complicated. The transformer has substantial leakage inductance, which prevents a very rapid rise in current – so the circuit is somewhat in a grey area between voltage- and current-fed class D. The trouble is that the leakage inductance resonates with the various capacitors, and the other inductors in the circuit, to produce several different resonant frequencies in the output network, all of which are driven by the switching transients. This results in a very complicated waveform with high amplitude ringing at high frequencies. Although the circuit “works” in the sense that it produces substantial 136kHz output, it results in high power losses in the PA components, if you are unlucky. I suspect that the reason some people have had problems with the MRF design, while for others it works well, is that the overall circuit behaviour is quite sensitive to the exact amount of leakage inductance, and so on the exact physical construction of the transformer. When the ringing occurs at just the right frequency, the circuit could act as a class ”F” amplifier, but that is another story…

 

The mods I came up with for the ‘MRF circuit aim to convert it into something nearer the “textbook” current fed configuration. Particularly, I tried to reduce the leakage inductance of the transformer – the original design had a leakage inductance of about 2.5uH, which has a reactance of the same order as the load impedance of a few ohms on the primary side of the transformer, so is bound to substantially affect circuit behaviour. The new transformer I described reduced this to about 0.25uH. Eliminating the “decoupling” capacitor and increasing the feed choke inductance makes the drain current a fair approximation to a square wave as desired. The reduced leakage inductance and the introduction of the “snubber” RC networks get rid of a lot of the HF ringing, and “simplify” the circuit behaviour. The low-pass, Low-Q output filter network means that the PA voltage waveform is not the ideal sinusoidal form, but seems near enough not to make a lot of difference. I have experimented with higher-Q tank circuits, and also with voltage-fed arrangements with a series LC tank, which do improve the waveform. However, since the circuit is about 90% efficient anyway, there is not a great deal of improvement to be had, plus the higher loaded Q circuits have the disadvantage of needing bigger, lower loss, output Ls and Cs which must be more accurately adjusted in value. Also, the low-pass configuration gives better reduction of harmonics; even if a higher Q tank circuit is used, an additional LPF will probably still be needed. Although the antenna itself will give substantial reduction of lower order harmonics, the switching transients inevitably mean that significant harmonics are generated throughout the MF and HF range at 136kHz intervals. It is unlikely that the antenna-plus-loading coil will give good rejection throughout that range.

 

Cheers, Jim Moritz

In the case of voltage switching class D and class E, I prefer to view the series resonant tank as an integral part of the amplifier. With such a tank in place, the output signal is already sinusoidal, with just a litlle bit of harmonics, and you can put any kind of lowpass filter after the tank without problems. Another thought on the small coil in the middle of the totem-poles in the Decca design: In addition to Andy's explanation that the coil will limit shoot-through spikes, I believe it also helps to reduce loss, when driving reactive loads, by throwing the external (and fast) catch diodes into conduction before the internal (and slow) MOSFET diodes and keep it that way until the other MOSFET turns on. The small "kickback" from the coil will put higher voltage across the external diode and the MOSFET diode will hopefully never start conducting. As soon as the other MOSFET turns on, it will shunt the diode(s) anyway since MOSFETs conduct almost equally well in both directions. 73 Johan SM6LKM From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 57332 invoked from network); 8 Jun 2004 14:34:22 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore02.plus.net with SMTP; 8 Jun 2004 14:34:22 -0000 Received: (qmail 73199 invoked from network); 8 Jun 2004 14:34:21 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 8 Jun 2004 14:34:20 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1BXhgC-000Ipj-J7 for dave@picks.force9.co.uk; Tue, 08 Jun 2004 14:34:20 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BXhfO-0002Bs-5c for rs_out_1@blacksheep.org; Tue, 08 Jun 2004 15:33:30 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BXhfN-0002Bj-Hk for rsgb_lf_group@blacksheep.org; Tue, 08 Jun 2004 15:33:29 +0100 Received: from smtp800.mail.ukl.yahoo.com ([217.12.12.142]) by relay.salmark.net with smtp (Exim 4.24) id 1BXoDt-0000KM-B4 for rsgb_lf_group@blacksheep.org; Tue, 08 Jun 2004 22:33:33 +0100 X-Fake-Domain: unknown Received: from unknown (HELO Main) (rsgb?lf?group@blacksheep.org@81.131.218.183 with poptime) by smtp800.mail.ukl.yahoo.com with SMTP; 8 Jun 2004 14:33:19 -0000 X-Bad-Message-ID: no DNS (Main) Message-ID: <001301c44d65$8c89e720$6507a8c0@Main> From: "Alan Melia" To: "LF-Group" Date: Tue, 8 Jun 2004 15:32:43 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4522.1200 X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: LF: LF PA "Efficiency meter" Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 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-PN-SPAMFiltered: yes X-Spam-Rating: 2 Hi all the technical chat about PA operation has reminded me of an unfinished project idea that someone might like to pick-up. It was stimulated by the need to tune a Class-E stage for maximum efficiency (usual technique to tune for PA FET drain waveform on a 'scope), but I guess it could be a useful tool in any Class of PA. Simply, the efficiency is approximately the PA (DC) current divided by the aerial of feeder current, so there is some "computation" to do. I considered a simple analogue multiplier, but then remembered the circuits of analogue computers from my youth. I am thinking that these latter circuits might be more rugged and easier to understand for most. ( no software or clever programmers required !!) A KISS solution ?? The idea goes like this....... use a high-side current measurement chip ....there is one made by Zetex but I have not doubt there are others. Some extra circuitry will be necessary to get it to sit 60 volts of so "up in the air" (see the Zetex app note) The voltage produced by this part is turned into a PWM stream (maybe a 555) referenced to ground. The feeder current is monitored with a current transformer (like Jim's tuning aid) but the output to a moving coil meter is interupted (chopped) by the PWM stream (100Hz or so). With the correct "polarity" of the pulse stream the level integrated by the moving coil meter will be a measure of the efficiency. Hence as the DC current increases the chopper gate is closed for less time giving a lower reading. I know it will not be an accurate measure of efficiency, but I was seeking a "peaking" meter to easily tune a Class-E stage correctly without the use of a 'scope. I have not patented this idea and offer it for the good of mankind and hopefully a help to LF operators. Yup I know you could do it with a PIC or some other device with a mega-bucketfull of transistors inside.....but I though this conceptually simple idea would appeal to the "hot solder-iron" fraternity (like me), and would be relatively easy to breadboard up. There may of course be a "theoretical hole" in my bucket....but I have no doubt someone will soon tell me !!

I have reported the matter to BT who hav been out to investigate but are unable to find the source or even say what it is. I have also sent a tape to David Lauder, the RSGB EMC guru but even he does not know what it is.

I would not lay too much store by BT "engineers" not being able to find it. These guys have little or no RF experience in general. Because it is so wirespread, I would suggest it is a system effect rather than a fault somewhere, and it would seem to correlate with the increased penetration of "broadband". This could explain why some "diss poles" are not as noisy as others. I do still have a collegue who is an amateur who worked in the EMC group at Martlesham for many years (now retired), after starting as an RI officer in N.London. He still has contacts and I believe does consultative work. I would be happy to send him the imformation /tape if you think it would help.

Another thought which might be relevant. I was struck by the relationship with telephone lines. A few years ago I had a box installed by the "telephone company who used to be a post office" that created 2 telephone lines out of one (they still made me pay for two) and which I eventually realised was a major noise source on 80 metres. It had a boolean logic which went something like: No lines in use = No Noise, No.1 line in use = noise burst approx every 2 secs, No2 line in use = noise burst approx every 2 secs, Nos. 1 & 2 lines in use = slow (5 - 10 wpm) random morse (or something similar). It went away when I eventually complained and they came and dug a hole and did the job properly so I could have ISDN. So I wonder if the LDO noise has a similar provenance

Hi
Very often such noise could be improved with a simple task, the first thing to try is connecting a bifilar wound choke where your telephone line enters the house. the next is to improve at your neighbours. Very often the balance is not what you might think, I've shown some of my own experience from telecomms on http://www.noding.com/la8ak/12345/n11.htm
A bifilar wound choke passes the balanced signal, but attenuates the unbalanced. Propose to wind a 2x 1mH choke (possibly much less)

Hi

Very often such noise could be improved with a simple task, the first thing to try is connecting a bifilar wound choke where your telephone line enters the house. the next is to improve at your neighbours. Very often the balance is not what you might think…

 

In the UK, the external line is supposed to be balanced, but the extension wiring inside the house is inherently unbalanced because it includes a third “ringing” wire (one of Dave Lauder’s favorite topics!)

My original objective was to be able to readily adjust the frequency of a calibration grade oscillator, for which fractional ppm is adequate. Your 0.5 Hz at 137 kHz is 3.6 ppm. Since my earlier report I received a request to check the slope of the delta emitter gradient, so that it could be used under automatic control in a phased locked loop. I checked a different design Colpitts crystal oscillator to "double check" on gradient matters. I confirmed that the technique worked for fine tuning each, but the slope was "opposite". So if a particular oscillator is to be used in a PLL application, it needs to be characterised for delta slope before designing the VCO drive. Someone reading these postings may have a suggestion as to the semiconductor mechanism(s) that bring about a variation in oscillator frequency. It would be unfortunate if some oscillator design had an S curve for frequency versus emitter resistance. 73, Bob ZL2CA ----- Original Message ----- From: "Lawrence Mayhead" To: Sent: Thursday, June 10, 2004 12:56 AM Subject: LF: re Xtal osc "delta emitter" tuning > Thanks Bob for the sugestion, I have been looking for a means to pull the > oscillator that I use for QRS and DFCW. > The cap. in series with the xtal gives me coarse adjustment and now the > emitter resistance change enables a "fine tune". > I am able to achieve 0.5hz shift in the final 137 khz output. although I > need to reduce the emitter resistance by 50% to > achieve this. > 73 Laurie. > > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 46282 invoked from network); 9 Jun 2004 21:35:58 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore01.plus.net with SMTP; 9 Jun 2004 21:35:58 -0000 Received: (qmail 3032 invoked from network); 9 Jun 2004 21:35:58 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 9 Jun 2004 21:35:57 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1BYAjk-0000Ze-Uw for dave@picks.force9.co.uk; Wed, 09 Jun 2004 21:35:57 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BYAix-00087L-H9 for rs_out_1@blacksheep.org; Wed, 09 Jun 2004 22:35:07 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BYAiw-00087C-Sb for rsgb_lf_group@blacksheep.org; Wed, 09 Jun 2004 22:35:06 +0100 Received: from virus-out.ttyl.com ([193.212.240.200] helo=virus-out-st.online.no) by relay.salmark.net with esmtp (Exim 4.24) id 1BYHHS-0004Ny-OL for rsgb_lf_group@blacksheep.org; Thu, 10 Jun 2004 05:35:10 +0100 X-Fake-Domain: tns-fbu-22-208.corp.telenor.no Received: from tns-fbu-22-208.corp.telenor.no ([134.47.162.90] [134.47.162.90]) by scan.telenor.net with ESMTP for rsgb_lf_group@blacksheep.org; Wed, 9 Jun 2004 23:34:26 +0200 X-Fake-Domain: tns-fbu-22-212.corp.telenor.no Received: from tns-fbu-22-212.corp.telenor.no ([134.47.162.91]) by tns-fbu-22-208.corp.telenor.no with Microsoft SMTPSVC(5.0.2195.6713); Wed, 9 Jun 2004 23:34:26 +0200 X-Fake-Domain: TNS-FBU-2E-006.corp.telenor.no Received: from TNS-FBU-2E-006.corp.telenor.no ([134.47.162.86]) by tns-fbu-22-212.corp.telenor.no with Microsoft SMTPSVC(5.0.2195.6713); Wed, 9 Jun 2004 23:34:26 +0200 X-MimeOLE: Produced By Microsoft Exchange V6.0.6487.1 content-class: urn:content-classes:message Date: Wed, 9 Jun 2004 23:34:26 +0200 X-Bad-Message-ID: no DNS (TNS-FBU-2E-006.corp.telenor.no) Message-Id: Thread-Topic: RE: G3ldo's noise Thread-Index: AcROPQDfyP20dU6wR9yQBl5WYwjfaQALGoFQ From: jan-martin.noding@telenor.com To: rsgb_lf_group@blacksheep.org X-OriginalArrivalTime: 09 Jun 2004 21:34:26.0471 (UTC) FILETIME=[89DCFB70:01C44E69] MIME-Version: 1.0 X-Spam-Score: 1.4 (+) X-Spam-Report: autolearn=no,HTML_40_50=0.474,HTML_FONT_BIG=0.1,HTML_MESSAGE=0.001,HTML_TITLE_EMPTY=0.544,NO_REAL_NAME=0.285 Subject: LF: RE: RE: G3ldo's noise (Internasjonal) Content-Type: text/html; charset=windows-1252 X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Level: * X-Spam-Status: No, hits=1.4 required=5.0 tests=HTML_40_50,HTML_FONT_BIG, HTML_MESSAGE,HTML_TITLE_EMPTY,NO_REAL_NAME autolearn=no version=2.63 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-PN-SPAMFiltered: yes X-Spam-Rating: 2 Content-transfer-encoding: 8bit

tnx,
and even the audio type of transformer were tested as choke on 2.048Mb/s PCM systems, but introduced 6dB loss, they are quite heavy, while only the difference between the to windings adds to the series inductivity of a balanced line

Hi

Very often such noise could be improved with a simple task, the first thing to try is connecting a bifilar wound choke where your telephone line enters the house. the next is to improve at your neighbours. Very often the balance is not what you might think…

 

In the UK, the external line is supposed to be balanced, but the extension wiring inside the house is inherently unbalanced because it includes a third “ringing” wire (one of Dave Lauder’s favorite topics!)

 

Cheers, Jim Moritz

Touche, Alberto!
 
The probem is (as my pal G3nyk often reminds me) is the misconception of what is referred to as "common mode" transmission of unwanted products (and sometimes "stray" wanted ones as well)!
EMC is an area in which it is still possible to surmise that "radio" is a black art in the sense that one man's solution is another man's experiment and another man's life's work.
Would that we were all gifted with "second sight". My own exp[eriences over the years tend toward the theory that much is instinctive and that if it works the investment in time as to cause and effect is academic due to the pressures of time plotted against the scale of the next problem!

Many thanks to all who gave their views on the effect of lowpass filters following 136 kHz power amplifiers.

I find the Reflector a wonderful medium for exchanging interesting info and I am grateful to those behind the scene that keep it running.

John,
 
Don't despair! You are putting out a good signal into this neck of the woods with your new system -I have been hearing you regularly . My antenna system is down at the moment due to other activities but I hope to join you operating hand sent CW again ere long!!

Hello again folks.
 
I have been sending copious cqs during the week and especially today, Sunday, morning. No reports of being heard so I wonder did anyone out there hear my signals I wonder?
 
I have made improvements to my antenna since I had contacts with Jim M0BMU and Tom, G3OLB last weekend and thanks to you both for the encouraging reports.
 
Since then I have put a second wire on the horizontal part to increase the capacitance ans it made quite a difference to the loading coil turns to achieve resonance with an increase in antenna current.  I have also increased the height of the top wires to 50 ft so I did think I would be getting somewhere. Maybe you were all outside enjoyong the sun and who could blame you?
 
Will be continuing with the calls as and when I can so if you hear me would you please report to me?
 
Thanks and 73 from John, G3JRL, Weymouth.

I don't think that the noise is generated by BT even though it is being radiated by some of their distribution systems. Last week we had a power cut that affected an area of around one or more km radius and the noise (almost) disappeared. I think most ISDN etc is powered from the exchange. All the interference comes down the antenna. I can reduce it considerably by parking my beam so that the deepest null is on the source of the noise. The noise is very broadband (I can hear traces of it on the 10 and 18MHz band) and is average S7 throughout the 14MHz so not an apparent harmonic.

Pair gain systems (0+2, etc), on the other hand- usually are powered from the exchange end, and would keep running despite local power being off. The former would be unusual in a suburban environment- the latter may be quite common.

I think it would answer Andy's question....that no he hasnt done tests on a calibrated range....I bet he has done a lot of simulation though!! Yep top-loading works I reduced my loading coil inductance by about 4:1 but there is a hell of a lot of wire up there. (capacitance increase from 180pF to 850pF at about 6pF per metre) but it is not near the vertical. -------------------------------------------------------------------------- "With my technique, I reduce the inductive loading that is normally required to resonate the antenna by as much as 75 percent . . . by utilizing the distributed capacitance around the antenna," he explained. "I looked at all the different approaches used to make antennas smaller, and there seemed to be good and bad aspects" to each, Vincent said. "A helix antenna is normally known to be a core radiator, because the current profile drops off rapidly; they are just an inductor, and inductance does not like to see changes in current, so it's going to buck that. "What I found was that for any smaller antenna, if you place a load coil in the middle you can normalize and make the current through the helix unity; that is, you can maximize it and linearize it," he added. ====================================== These comments do not stack up with radiation resistance changes (necessry to actually radiate more power) but LFers will know the effects of putting capacitance around the aerial ...(trees, bushes, bean-poles, houses etc)....and it is not to get a stronger signal at distance. We shall see. I cant find the Patent No quoted anywhere. The compression he achieves seems about the same as a mobile whip, and you can work round the world on 21MHz mobile with a 1.5m whip and about 100watts....some have been doing it for years. I am fascinated to know what the other "terminal" of his capacitance is connected to!! Or am I being too cynical? Results need to be repeated before they are hailed as breakthroughs. The acceptance by a patent examiner is not sufficient proof of this. There may not be many perpertual motion machines getting through these days but there seem to be plenty of other "strange science". Rhode Is Univ (where??) will probably fight detractors as it seeks to pull in cash, the finances overpowering the scientific method. As a physicist I am saddened. I fear its another case of science by press release, cold fusion all over again.

Hello all.
 
I would like to thank those who kindly called me and gave reports last weekend. Also thanks to those who sent me e-mails.
 
I wonder Bryan (G3GVB) if you did copy me on Sunday at 1000 as you suggested? I was on working others at that time.
 
Thank you Tom (G3OLB), Werner (ON6ND), Laurie G3AQC), Jeff PA0SE, Dick (F6BWO) for the fine qsos and reports all of which enabled me to assess the progress I had made, and need to make. Thanks to you Alan (G3NYK) for the reports and all the advice and your suggestions for the future experimentation.
 
Thanks to you Derek ( G3GRO) for your e-mail. Glad you have followed my progress and hope to have that qso with you soon.
 
It was rather a pity that there was so much QRN which prevented perfect copy. Jeff, I think I was mean with my report to you as I really could copy a lot of what you sent to me and Werner. The QRN was S6 with me and I have noticed that it has increased gradually as I improved my antenna. Fairly obvious I guess. I do use my tuned and amplified loop antenna for reception placed so that it does not pick up local qrn but the main tx antenna is now inducing QRN into the loop so I guess maybe I should move the two apart if I can.
 
Further activity will be during the weekend as I try to improve what I have during the week between much gardening.
 
Thanks to you all and thanks for the interesting discussions I see on Reflector. My tx is based on G0MRF design so of course it has got me thinking how I should experiment with mine.
 
73 From John, G3JRL.

It seems to operate very well & the frequency stability is far superior to the FT-747GX & sensitivity to me seems to be quite good, it just needs a narrow IF filter. I now want to get hold of a circuit diagram (not that it needs any attention) for reference etc. Can anyone tell me of a source of a technical handbook or diagram for the JRC NRD-345 as the user handbook is very basic.

have you tried any of the major electrical wholesalers eg Newey & Eyre, Wholesale Fittings, etc.? Years ago people like BICC and AEI used to do them so it might also be worth enquiring of some of the big cable distributors.

For most of the time we will have a DFCW120 beacon running with the usual QQQQ.... identifier, frequencies 137.7890/137.7886 kHz. ZL hours of darkness are between nominally 0452z to 2006z. To assist with weak signal identification, timing can also be used, as we will arange for each Q to be synchronised with starting on the hour and each ten minutes thereafter. We expect that frequencies will be maintained within 0.1 Hz of declared. The beacon should be running from ZL sunset (so DX could be possible in paths with an east component from about 0452z). At 0900z we are breaking the beacon transmission so we can try for an LF SSB QSO with Robert AX2TAR (in VK7). How long that may take depends on how propagation turns out and whether each station is functioning to expectation. At some time ZM2E will attempt an LF/HF crossband QSO with Laurence 3D2LF in Fiji. 3D2LF can use the DFCW beacon as a propagation indicator, and we can listen out on the 40 metre liaison frequency, so there is flexibility in when the crossband QSO could be attempted (apart from at and after 0900z when we will be on SSB looking for AX2TAR). We will maximise our time with DFCW120 beacon transmission, and there should be a continuous output over the latter part of the ZL night, to suit paths with a west component into Europe (but admittedly it is a very long way). Good luck to all who tune in. Argo works well even when you are looking at your eyelids :-) 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14827 invoked from network); 25 Jun 2004 02:03:45 -0000 Received: from unknown (HELO ptb-mxscan03.plus.net) (212.159.14.237) by ptb-mailstore03.plus.net with SMTP;

To me this does not make sense, but maybe I am missing something...any thoughts anywhere?? I can see that the small inductance of the very short (45feet..14m) "radial" could "impede" the passage of current collected at the remote ground spike, but I do not really see what is happening. We may have to wait for the article to hear the full measurement detail. I am worried that he has measured the soil conductivity at 60Hz ....this has little relation to ground loss effects at 136 to 180kHz....though maybe if it drops at 60Hz it is somewhat better at 136 ?? --------------------------------- Hi Eric, I'm working on an article for an upcoming LOWDOWN on the system, but briefly, it goes like this; at the far end of EACH radial is a 4 or 8 ft ground rod (most are 8') with a series capacitor between the radial end and the ground rod. This capacitor is VERY important as it cancels out the XL of the buried radial and really maximizes the available current in said radial.Here, on a 45' radial(the longest) it requires a 0.047uF value. On the 20 footers,(the shortest) it runs about 0.15 uF. The bad news is I have 134 radials!! Lots of expense and lots of exercise.(I LOVE to experiment) Hope this info helps you. 73, Ed G. ------------------------------- 0.047nF resonates with 29uH at 136 and about 16uH at 180Khz....my belief is that a short wire (less than a 1/4wave is capacitive not inductive at LF, though a straight piece of insulated wire measured away from resonance will have some inductance. My though is if this really does work it could be helpful tho those with short back gradens, but I worry that Ed may not have measured the aerial system properly and could maybe be fooling himself (I've done it myself before I started to use an RF bridge) I am not trying to nit-pick on Ed's energetic works, but would like to ask him the right questions (maybe suggest some different measurements) so that we could, maybe, understand what is happening.

Dear Alan, LF Group, I tried some experiments along these lines a year or so ago, and can confirm that the length of the wire connecting to the earth rods does indeed make a lot of difference to the distribution of current. For a wire near ground level connected to a ground spike at the far end, I reckoned that the inductance was of the order of 1uH/m, and radials of the order of 10s of metres long therefore have inductive reactance of the order of 10s of ohms - comparable with the resistance of the ground rod - soil interface. The result of this is that if you have numerous ground rods at different distances from the feed point, the vast majority of the ground current flows through the few rods nearest the feed point, since the return path for the antenna current through the ground has lower overall impedance than the path through the longer radials. This is one of the reasons why adding to the ground system does not make much difference to the loss resistance of the antenna once you get past a certain number of ground rods/radials - the more distant ground rods carry very little current, and so make very little difference to the current paths and losses. "Ed G"'s capacitors are one way to even up the impedance in the different ground paths (if you assume 1uH/m, they come out about right at 180kHz) - I tried two other ways. One was to have a central connecting point for all the ground rods under the centre of the antenna, connected via a "bus" wire back to the (inverted L) feed point . The 12 ground rods were in a rough circle, so current had to flow the same length of wire to get to any ground rod. The other way was to add inductance in series with the shorter ground connections to give them roughly the same impedance as the long ones. (Note that in either case, the ground connection at the antenna is somewhat above "earth" potential at RF, so an isolating transformer or common-mode choke in the TX feed is needed to stop most of the current flowing in the transmitter earth connection). Both techniques were succesful in producing roughly equal current in all the ground rods, but the bad news was that, in spite of trying several configurations, only about 10% reduction in antenna loss was achieved (i.e. about 0.5dB improvement). I went back to the original ground system of 6 rods within a couple of metres of the antenna feed, because by now the garden was festooned in wires with ground rods poking up everywhere! Looking in the literature, similar schemes for producing even ground current distribution used to be popular for VLF antennas in the 1920s and 30s, some with elaborate systems of "balancing coils" and over-ground distribution wiring, and "multiple tuned" antennas, but these seem to have been replaced later by very extensive buried radial systems, which gave better performance with fewer maintenance problems. As discussed on the reflector some time ago, and based on this and other experiments, I came to the view that for typical amateur antennas, the majority of the loss occurs as dielectric loss in the ground due to the electric field of the antenna, instead of in the ground return path resistance, as seems to be true of the larger professional LF and VLF antennas. In order to reduce this significantly, there would have to be a large enough number of radials to form an electrostatic screen between the antenna and the lossy soil underneath. Maybe 134 radials is enough to achieve this, but I think they would also have to be quite long in order to intercept most of the electric field around the antenna. For Eu amateurs, I think a more effective approach would be to increase the amount of top loading capacitance, so reducing antenna voltage and dielectric loss - but of course, the Lowfer part 15 regulations place severe limits on the amount of wire in the antenna.

Speeds were slowed in the end to dot3 and straight CW mode as I had problems (mine!) reading the dfcw. Now I realise I should have reduced rx/argo gains - Ill know better next time. Signals from ZM2E were 559, reports and they were having more difficulty with my 40m SSB signal! Signals continued to build until a test message at 15 wpm CW were fully 559 in Pacific harbour Fiji. More details later but an early test on LSB SSB from ZM2E to me here were unsuccessful - I had to go for food and wine early so Ive left the rx on and will look at the signals when I get to the shack (sending this from a coffee shop). Nothing from Ed overnight - no sgn on DCf39 at all This will be the last day I will look for Hifer signals as I will switch the rx to listen on LF for the next 5 days and nights whilst we are away on another island - ill centre the rx on XFX/XES/DCF39 and 137.8 areas and will review captures when I get back.

As Laurence 3D2KL has already reported, we had a successful crossband 137k/7M contact with him, including 15 wpm CW, even though it was fairly early in the evening. As Laurence reported good LF signal strength from the DFCW120 beacon, we started the QSO with DFCW10, so any DX listeners in North America with 120 second dot length setting would have been rather compromised. The QSO took place between 0550 and 0710z. We were unsuccessful with trying to have an SSB contact with AX2TAR (in VK7). We tried from 0900 to 1000z, so there was no beacon during that hour. The DFCW beacon ran for three sessions: - from before ZL sunset till 0550z, - then from 0710 till 0900z, - then from 1000z till after ZL sunrise around 2000z. The next booking for LF tests is the September equinox. 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 86965 invoked from network); 27 Jun 2004 04:34:46 -0000 Received: from unknown (HELO ptb-mxscan02.plus.net) (212.159.14.236) by ptb-mailstore02.plus.net with SMTP; 27 Jun 2004 04:34:46 -0000 Received: (qmail 83248 invoked from network); 27 Jun 2004 04:34:45 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore02.plus.net (212.159.14.216) by ptb-mxscan02.plus.net with SMTP; 27 Jun 2004 04:34:44 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore02.plus.net with esmtp (Exim) id 1BeRNM-000LR0-Ae for dave@picks.force9.co.uk; Sun, 27 Jun 2004 04:34:44 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BeRMc-0004AY-Mw for rs_out_1@blacksheep.org; Sun, 27 Jun 2004 05:33:58 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BeRMb-0004AP-Ns for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 05:33:57 +0100 Received: from bay12-f92.bay12.hotmail.com ([64.4.35.92] helo=hotmail.com) by relay.salmark.net with esmtp (Exim 4.24) id 1BeXv0-0007I0-B9 for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 12:33:54 +0100 Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Sat, 26 Jun 2004 21:33:40 -0700 Received: from 202.62.127.207 by by12fd.bay12.hotmail.msn.com with HTTP; Sun, 27 Jun 2004 04:33:40 GMT X-Originating-IP: [202.62.127.207] X-Originating-Email: [hellozerohellozero@hotmail.com] X-Sender: hellozerohellozero@hotmail.com From: "Laurence KL1X" To: rsgb_lf_group@blacksheep.org Date: Sat, 26 Jun 2004 20:33:40 -0800 Mime-Version: 1.0 Message-ID: X-OriginalArrivalTime: 27 Jun 2004 04:33:40.0504 (UTC) FILETIME=[EBDB9180:01C45BFF] X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: RE: LF: ZM2E and ZL6QH operations Content-Type: text/plain; charset=windows-1252; format=flowed X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 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-PN-SPAMFiltered: yes X-Spam-Rating: 1 Content-transfer-encoding: 8bit Now looking thru the overnite shots the peak from zm2e in 3d2 was just a couple of hours before dawn in Fiji when the signal was huge - Im guessing a high S number and Im sure a SSB qso would have worked then (I was sleeping about a mile away!) - ill forward captures to bob and anyone else that want them.

It much decrease if one use elevated radials, not burred. But in this case seems 'ground' system should be isolated good from real ground (it is worth!). Certanly one should use a transformer to feed such an antenna (TX box is connected to a ground usualy). Height of radials should be about 0.5 - 1 m. Certanly this is reasonable only if there is no trees, buildings and so on around an antenna. Unfortunely I have no oportunity to do comprehensive experimental test of this. 73 de RA9MB/Alex http://www.qsl.net/ra9mb From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18080 invoked from network); 27 Jun 2004 09:00:34 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore04.plus.net with SMTP; 27 Jun 2004 09:00:34 -0000 Received: (qmail 41806 invoked from network); 27 Jun 2004 09:00:33 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 27 Jun 2004 09:00:32 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1BeVWa-000Ai7-6K for dave@picks.force9.co.uk; Sun, 27 Jun 2004 09:00:32 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BeVWI-0002C6-KC for rs_out_1@blacksheep.org; Sun, 27 Jun 2004 10:00:14 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BeVWI-0002Bx-7c for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 10:00:14 +0100 Received: from mx.omskcity.com ([81.176.48.2] helo=astral.omskcity.com) by relay.salmark.net with esmtp (Exim 4.24) id 1Bec4g-0007ai-85 for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 17:00:10 +0100 X-Fake-Domain: noname.nodomain.nowhere Received: from noname.nodomain.nowhere (host196.m02.dial.sotline.ru [81.176.51.196]) by astral.omskcity.com (8.x.x) with ESMTP id i5R8tnor027620 for ; Sun, 27 Jun 2004 15:55:49 +0700 (OSS) Received: from localhost (fitec@localhost) by noname.nodomain.nowhere (8.8.5/8.8.5) with SMTP id PAA00250 for ; Sun, 27 Jun 2004 15:09:35 GMT X-Authentication-Warning: noname.nodomain.nowhere: fitec owned process doing -bs Date: Sun, 27 Jun 2004 15:09:34 +0000 (GMT) From: "Alexander S.

 Hello LF'er,
 
Any information about this station in CA ?
 
 
164.900 KHz  KLFB  Sunnyvale, CA  CM97  AM Mode;music 7AM-11PM daily, 770 Hz tone other hours.
 
 
Maybe a good beacon for LF, though a little bit near" France Inter" in Europe...(162 KHz, 2MW in JN17)

European LW broadcast stations are almost never heard in California, and even the Experimental Service licensees on 166kHz don't put much signal strength out there, so Ed Gelinas has a relatively signal-free environment for covering his neighborhood. He has only operated it with amplitude modulation so far, but is considering operating it as a conventional Morse beacon during his "non-broadcast" hours later this year.

I am making every effort to have my 2200m beacon copied in Europe this coming winter. As my QTH is just about dead center in the United States this is going to be a huge challenge...for me, *and* for the intrepid individual that actually manages to copy it! Currently only operating at 110 watts I'm working on the G4JNT 700-watt switcher that I'm planning to have on the air by 31/10. I know that due to my land-locked location this may well be an exercise in futility, but I'm going to give it my dead-level best shot. 73 Eric http://www.nutstreet.net/xfx/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 52418 invoked from network); 27 Jun 2004 20:34:54 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore03.plus.net with SMTP; 27 Jun 2004 20:34:54 -0000 Received: (qmail 95573 invoked from network); 27 Jun 2004 20:34:54 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 27 Jun 2004 20:34:53 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1BegMX-000OkI-Ii for dave@picks.force9.co.uk; Sun, 27 Jun 2004 20:34:53 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BegM3-0002Ss-BU for rs_out_1@blacksheep.org; Sun, 27 Jun 2004 21:34:23 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BegM2-0002Sj-TU for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 21:34:22 +0100 Received: from mail.libertysurf.net ([213.36.80.91]) by relay.salmark.net with esmtp (Exim 4.24) id 1BemuR-0000BK-QP for rsgb_lf_group@blacksheep.org; Mon, 28 Jun 2004 04:34:19 +0100 X-Fake-Domain: jeff Received: from jeff (213.36.64.36) by mail.libertysurf.net (6.5.036) id 40DE4F7000134ACE for rsgb_lf_group@blacksheep.org; Sun, 27 Jun 2004 22:34:06 +0200 X-Bad-Message-ID: no DNS (jeff) Message-ID: <001b01c45c86$2a8a5b60$244024d5@jeff> From: "F6CWN" To: rsgb_lf_group@blacksheep.org References: <167.3131809f.2e1074be@aol.com> Date: Sun, 27 Jun 2004 20:34:36 -0000 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1106 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: Re: LF: Re: CA Broadcast TX, LF beacon?

Great news, i'll try to receive your signal from my QTH in West coast of France ( JN09TT ). In winter i thing that the propagation will be better... My equipement at this time is a loop 2.15m (85") 5/8" heliax cable. I'm working on a new preamplifier ( symmetrical to keep high Q of the antenna ). The kite antenna do not works ( 110m/ 360' AGL) on RX. The problem is the high noise level of QRM by LORAN, DCF39 and so on... The second trouble is coming from the stability of the oscillator of the receiver, essential for a good running of the QRSS mode ( QRSS120).A stability control with GPS ( PPS) is under consideration ( breathing in W5OJM desing! ). The transmit equipement is also under construction ( watter cooling) with BSM191 from Siemens, i have some problems with input capacitor ( CIss)...

On front of the receiver i use a bandpass filter ( Cheb. .2 dB ripple, 11 KHz BW , 7 poles) to reject part of "QRM", the mixer is a SRA8 from MCL, the LO is a 5 MHz OCXO and some MMIC in buffer. The IF is a FT847 with 300 Hz Xtal filter. My main problem is that the loop antenna is ~120m (~390') from the station and i pick up some crazy thing by the braid of the coax cable... The new preamplifier (two match U430 Siliconix) and CV tune system is not finish at this present time. Give me some time, i am a novice, just escaped from VHF!

You will know it by the loud groans from over here, and the cheering from Alan! There is no other continuous high power source from the U.S. near the 137 kHz band. There will be more experimental stations on the air by next winter, though, so stay tuned. My operation is intermittent, but I try to give advance notice on this mail list if conditions look good.

For anyone interested here's a 'small' image that says it all about the signal on 133.1KHz.
 
 
I believe the signal is coming from the Canadian Naval base at Esquimalt,BC, Canada(west coast NA).  My RX was centered on 133.1KHz in CW mode which implies that 800Hz in the image = 133.1KHz.  The deep null noted ~675Hz has been there since the signal stopped modulating a couple of weeks back.  The 'new' signal on ~76.2KHz looks exactly the same.  Normally this station runs with some kind of MSK? and turns off completely maybe once every week or two for a day or so. However, of late they seem to be playing with it as the above has been the only signal sent for a couple of weeks now.
 
Any reports of the reception of this signal would be of great interest to me and Steve, VE7SL.
 
LowFER 'TIL' is now off and being modified for 2200m operation.

The current in the aerial was 2.4-2.8A (during a rain 2-2.2A) Any successful rpts from ZLs, Laurence(3D2KL), NA or SA has not received. June 26 I tried to RX a beacon ZM2E - without success - very strong local QRN.

Not many seem to be doing this any longer, but an audio power amplifier is a possibility. I'm using an unmodified Hafler P3000 amp at the 200 watt level. Picked it up from eBay at considerably less than the new price. I confess to not having made any linearity measurements, though, and it's possible that the thing is less than perfect. I haven't gone beyond 100 watts in the continuous key-down modes, partly out of respect for the present output transformer and low pass filter. All of the bits are here for heftier versions of both, and they should be ready for the next season. I do have two small fans blowing air through the amp's heat sinks, and that makes a big difference.

Hi All
LF bands still good for dx. ZL4PO is a good signal every evening here on 3506 khz. Have worked him 3 nights in succession, replied to his CQ. Its possible condx on 137 khz are also good. QRN at this time of year could be a problem for some.

I'm trying to write some code to communicate with the Connexant Jupiter T GPS module, as used in the simple GPS Disciplined Oscillator mentioned on these reflectors recently. It isn't necessary to 'talk' to the module for the GPSDO to work, but I want to to be able to do this in order to add GPS validity checking, and get a diplay of time and location from the NMEA string. The problem is this : I have an RS232 connection set up, the flash boot mssage appears on the display so I know the serial link is working. I can generate (what I think are) the correct binary values and checksums to send to the module, but there is no acknowledgement at all from it - just appears deaf and dumb. If anyone has managed to communicate with one of these, can I have a look at either your source code or at least an exact set of values to send to the module to ellicit some response. Ultimately, all I need to do is to send it the correct data needed to output NMEA data so it sends the GPSRMC string once per second, so all my existing PIC software can read the data it wants.
