Thanks again, Markus. The EbNaut is being sent as I type. 73 Joe VO1NA Resending this to Blacksheep, in case anyone else wants to try it too. The mentioned .ini configuration file and a screenshot ar
That's quite amazing, Paul. Well done with EbNaut and your RX! Many thanks to those who have patiently guided me to this point, especially Markus, Stefan and yourself, and to Wolf for SpecLab. Joe VO
Thanks Markus - of course you Stefan and Paul should be credited with your patiently helping me. The PSK is now off -- just the carrier now. 73 Joe VO1NA Somewhat belated I guess: My congratulations
Hi VLF, There was a phase glitch at 1700-1800 ut today. It was a nice day for aerial work and so hopefully the ERP has improved a bit on 8.2700075 kHz. It is hoped to launch a few hundred billion VLF

Hello Markus, Paul, VLF, Very encouraging news with the spectrograms from Germany, but strange how the sigs disappear in England from time to time. Thanks Paul and Markus. An arced coil was replaced
Hm, we need evidence for claiming such distances i find. From my spectrogram i can see no clear trace on the exact frequency. I'm running another spectrogram in the background, not displayed on the g
Yes Stefan I agree, the small peaks are no more than a vague indication and not yet near a proof of reception. Hope they are anyway encouraging. Joe are you now using the higher antenna, or perhaps b
Yesterday I raised the far end of the low RL in an effort to get the voltage and inductance down and the ERP up, but instead managed only to fry a coil. I'll keep the carrier on and think about the n

FB WX today so the far halyard on the rotated L was taken in for another increase in the average height of the aerial. This is the first change since 25 Oct. The aerial current did not increase and t

That's good to hear, Paul. There were some minor changes to the aerial today so perhaps there may be a small phase shift. Hopefully the S/N will improve when that strong signal moves up the band toni
Received with a couple of dB to spare. Copied 'DIRAC' at Eb/N0 = +1.8 dB, BER 40.5%. Constant reference phase, list rank zero. Symbol error map http://abelian.org/vlf/tmp/171106a.gif -- Paul Nicholso
