Hello Jim, Markus and group. Your TX hardware does not ignore it, Jim... my receiver ignored it in the QRM, and it was not visible on the spectrum here. But it can be seen in a screenshot of your tra
Hello Jim and group, Fine copy on Jim's PSK08 transmission at 137.500 through the local 50Hz QRM (received with an indoor ferrite antenna and a TS850, the signal was not audible but decodable). Unfor
Hi Dave, Jim and group, Thanks for the PSK08 QSO between DF6NM and myself. The frequency must have been something like 137.7025 kHz +-0.1Hz, and there was possibly a small difference of 0.2Hz between
Hello Andy and group, I had perfect copy from Andy's transmission even without a high-precision clock source (just a homebrew OCXO). My receiver was not at the correct frequency precise enough so the
Hello Dave and group, This was definitely a "phase shifter's friday" ... after Andy's successfull test transmission, I got perfect copy of your PSK08 transmission though the signal was hardly audible
Hello Uwe, Thanks for the "reception report" and for the Loran- and DCF39 diagrams. I don't think the phase jump on DCF39 is a technical fault, it has been this way all the time (at least a couple of
Hello Fabian and group, Thanks for the warning. Fortunately my mail browser does not try to open an attachment in "preview mode" or similar. I copied the attachment to a floppy disk and opened it wit
Hello Geri, Dave, Uwe and other 'hell watchers', I could copy Geri's hell TX here at, though much worse than visible on Uwe's screenshot. As Geri said, FeldHell is not the ultimate mode for LF, the r
No reluctance to build extra hardware ! But consider how difficult is to get some of the DSP's, CPU's, evaluation boards etc these days for those non-professionals. Waiting a couple of weeks for tha
Hi Andy and group, Yes here is someone with both vectorscope and PSK demodulator (the "differential" type), so I would like to go for a test at the weekend. Not much hope to receive you from my home
Hello group, I will be QRV this morning in JASON, PSKxx and of course normal CW around 137.4...137.5kHz. (Sorry Markus for calling you in CW yesterday, I had no PC here and was too curious where the
Hello Group, Thanks to all for the reports. Concerning PSK31 and PSK08: In fact there is an implementation of PSK08 in Spectrum Lab, but it's not very user friendly and not really optimized (in fact,
Hi Jim and group, M0BMU's test transmission is still going on, and -a bit to my surprise- at this moment I can copy it 100 percent from my home QTH with a small ferrite antenna, 5 meters away from th
Hi Jim and group, I will be listening for you later and -if WX permits- try to answer from DF0WD. The local noise at my home location is horrible, an ugly mixture of moving and fixed carriers spaced
Hello Mike, The HAM Radio in Friedrichshafen this year is from June 28 to 30. If you consider going there, it's a good idea to make hotel reservation early (or go camping on the banks of the Bodensee
Hello group, There was good activity on 136kHz at the weekend, heard a lot of stations and worked a few. Beautiful weather with sunny blue sky and almost +18°C, so not much time spent in the shack. S
Dear all, Some QRSS activity on Saturday. Seen or heard close to 137.70 kHz: IK2DED (not audible but "O" copy, thanks for qso, new one for DF0WD) IK5ZPV (audible) OH5UFO (audible) M0BMU (very audible
Hello Group, On saturday morning around 09:00 UTC there was a quite weak signal (barely audible) near 137.79 kHz, not identified because I had no PC at the club stn. It was too strong to be DX in the
Hello Andy and group, Instead of using the 1kHz reference signal as a sample clock for the soundcard (which may be a *very* tricky job), why not use 1kHz as a reference to determine the 'true' sample
Hello Group, if there is someone out there ready to transmit, look for DJ3QO on 136.5kHz. The signal is very strong here with a short untuned wire plugged into my TS850, but that is no wonder because
