Hi VLF, Since 23 UTC a 700 mA carrier is running on 17.4701 kHz! It is a little surprise to the VLF community i think ;-) Legal? Yes: http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/17,47kHz_Sonder

Hello Markus, thanks for the feedback. Wonderful, now it is 30 dB in 424 uHz. DL0AO could run a 3.8 mHz '600' RDF spectrogram and a phase and signal level plot, so we could see propagation effects mu

Left it on overnight. Would you like it on 24/7, I see diurnal variations similar to Marcus but more pronounced due to my lower signal strength. 73 Eddie On 27/11/2017 20:30, g3zjo wrote: Hi Stefan I

Hi Dave Stefan's e-probe design for 8.7kHz antenna and sound card RX. The BPF in the probe has quite some cut off outside sub 9kHz but maybe that's good due to the adjacent big boys. 73 Eddie On 28/1

Hi Stefan, VLF I got your signal in JN64bw, dear Stefan. Depending on the QSB and/or QRN, you're peaking 15dB over noise. Fantastic! :-)) I'm using my LF antenna tuned on your QRG with a (approx.) 20

GE dears, I'm also following your TX, Stefan, with a 424 uHz grabber with no result at the moment. I'll try also the 42 uHz one. As antenna I'm using the MF TX marconi because whip and loop are ready

Hello VLF, The TX was switched OFF at 19 UTC, so the carrier was on air for 116 hours :-) Since 20:30 UTC it is now back at 1 A antenna current, 3 dB more. The QRG is still 17.470100000 kHz 73, Stefa

Hi Stefan, good to see the carrier back, I've already been missing that cheerful green trace on DL0AO ;-) But it looks like the phase is inverted now. Did you happen to change something about the pic

...there has been an interruption of the carrier between 23:00...23:50 UTC. It is now back with opposite phase, i.e. the same phase as during the 700 mA test. 73, Stefan Am 30.11.2017 22:21, schrieb

There were a number of interruptions. The carrier stopped arround 4 UTC. It was restarted arround 9 UTC but stopped again 20 minutes later. The reason is heavy snow which triggered the safety functio
