Hello Paul, ULF, Thank you for working out the signal so clearly. The accurate frequency matching is an ID in itselfe. Most impressing. It was an exciting and unique experiment taking months from the

Hi all, Just in case someone new or old wants to try, i'm running 700 mA again on 8270.005 Hz until 05:30 UTC. It is a first test for a new RX stn on VLF! If the trace will become visible, it would b
Hello Max, Oh, yes indeed! Very nice, thanks. http://www.ik0vve.net/?page_id=377 is the link (i had to search some time ;-) ). With this level, EbNaut should be no problem. But somehow we didn't mana
Hi Max, What about a new attempt for your first EbNaut message? The signal should be strong enough. Are you ready? 73, Stefan Am 29.03.2017 07:26, schrieb Max IK0VVE: Hi Stefan & friends, despite the
Hi Eddie, Also thanks for watching! Where can i see the trace? A link or a screenshot? Yes the plan is to wind smaller stacks that allow various combinations and resonance frequencies. Also i thought
Hi Domenico, VLF, OK, then i will try a new attempt for a first EbNaut message to south Italy. There will be improvements at RC4HAA this weekend, so more carriers will be required then. You can use t
Hi Joe, Your recent emails came through now, with some delay since the 27th. Thanks for your kind words regarding ULF. We are waiting for your signal on VLF. A true RX challenge for me! If you need h
Hello Alex, Thank you, the message is correct! :-) Very well! And 1990 km during the relatively high QRN! But Eb/N0 = -0.3 dB, that's quite close to the limit. On the other side the transmission just
Hi Joe, I changed the subject ;-) The settings were not bad, just the delay/echo line was enabled, which is not necessary. In attachment is another usr file with some more complex settings optimised
VLF, Between 22:04 UTC and 23:20 UTC there was a test carrier on 6590 Hz. The average antenna current was 470 mA. I wonder if Paul or Jacek did see a trace? The QRN is extreme this night. 73, Stefan
Hi Paul, Many thanks. Not bad at all. Would be fine for a 20 character message in a single night. I did not expect such a signal in such high QRN levels. I'm not yet on the target frequency though :-
Hi Joe, I thought about the hill you have been recently. Was it 'signal hill', where the signals from Marconi were received? That would be a nice place for a grabber! But of course there must be inte
Hello Jay, Thanks for the capture! I was watching your grabber last night and saw the dropping SNR. So it was a QRN issue, all right. I've seen positive DST values. Is that good or does it become wor
Hello Tobias, Thanks for the good explanation. Well, i remember some further problems. Do i remember correctly that it is no actual NAVTEX mode, i.e. no sync tone to the beginning? The message "ZCZC
Hello John, Probably this was my signal, i've been transmitting Opera 32 until 8 UTC on 137.573 kHz. BTW i got a report by KU4XR in Tenessee: opds Results from overnight in Friendsville, TN. - EM75xr
Hi Bob, OK, maybe you're right. I will switch to OP32 later. Now some DFCW-180 for JA and VK :-) 73, Stefan Am 29.03.2014 18:54, schrieb Bob Raide: Stefan; Seems better OPERA activity here on 137. No
Hi LF, I see that DF6NM and SV8CS as well as DK7FC are TXing in the EU DX window arround 136.172 kHz :-) The condx to VK look promising again! Good luck! PS: The YO/4X1RF grabber is available again,
Markus, LF, Good good! I just found TF3HZ's grabber back on line. Worth to fire out some kWh of RF energy... :-) 73, Stefan Am 17.04.2014 21:07, schrieb Markus Vester: yeah we're striving hard, makin
Hi LF, There is quite a high LF WSPR activity this evening it seems. Some WSPR-2 activity in the UK convinced me to try WSPR-2 too. And it works ;-) Now i'm toggling between WSPR-2 and WSPR-15. Condx
