Greetings all, Just worked G3JKV from IO91UF ... ... in SSB on 144.3 MHz ! Realized a bit too late to suggest trying LF / VHF crossband; so Walter, if you are still on, please try again on 144.300 MH
Hello Graham, I assume you use one of the "stable" (not "unstable") releases... I recently modified the buffer structure to support very long FFT's, which caused some problems with the memory allocat
Hello Paul-Henrik, I am not sure if this applies to the NRD-91 too, but with serveral radios used here (including, but not limited to KenwoodYaesuIcom), it's important not only to turn the AGC functi
Hi Gary, Are there any circuits available for this type of transverter please ? Unfortunately no... only a few photos, since I never made a complete drawing. I built the transverter stage-by-stage, a
Hello Andy, you wrote: Also, what looks like data at 80Hz - could that be a ULF submarine transmission? I have forwarded the question to Renato, and indeed the 82 Hz signal is from a Russian transmit
Hi Gary, I use an IC706 (first model) for my 136 kHz transverter, and it works like a charm (with the CW filter of course). The nice thing about this radio is, all oscillators are derived from a 30 M
Greetings all, Not LF or MF, but this may be interesting for some group members: Renato (IK1QFK) has set up a new automated ULF / ELF monitoring station : http://www.vlf.it/livedata.html It measures
Hello Jean-Pierre, Thanks for running the grabber (which I frequently visited in the past weeks). I don't think that the dynamic range of the spectrum display in SpecLab has changed that much, but th
.. at this moment, very nice audible copy on ~501.3 kHz, at DK4U (JO42FD). Using the 200 meter "long" wire temporarily, and the IC706 (no converter). Looking for crossband activity now; 40 meters pre
Hello Brian, Nice to see you're back on LF (also TX-wise) ! Hope to work you again some day on LF, if winter conds permit. At the moment, no visible signal at my home QTH. But I will look for you as
Hello Dave and the group, Thanks for the screenshot dave. Nice to know the old TX still works as it should (and doesn't cause too much unwanted sidebands in this "linear" mode). You caught the final
Greetings all Mal: Maybe your countrymen are busy working Russia on 144 MHz / CW / troposcatter this moment (not kidding, wkd GM4ODA/p on the Shetlands, OY9JD / Faroe, UA2 .. UT2 yesterday, and these
Hello Hartmut and Uwe, Similar thought here.. why not simply join the crowd in the "european DX transmit window" at the lower edge of the band ? Anyway, not a big problem here since I don't have Hart
Hello Jean-Pierre, I tried two times to send a msg to you; both bounced. Your message concerning the spectrogram AGC has arrived here. Do you have an alternative email address (besides the ...online.
Hello Jim and the group Stronger local noise here this evening, on my unmatched short attic dipole connected to the TS 850. Your signal is absolutely invisible on the spectrogram, but decodable in WO
Dear Hans-Albrecht, Nice to meet you again (I think last time was in Friedrichshafen..) ! I saw weak traces of a caller after my qso with Ed 'LA, but due to the horrible FSK-QRM from EFR's transmitte
