Indeed. I joined in August 1998, and kept ALL messages since then. About 40.000 messages so far ;-) It was very interesting. UK OM had the some experience from 73 kHz operation, I had none. I started
Thanks Peter :-) In 1998 it was me to propose here the use the "T-M-O" reporting mode, as used in EME, for LF. It's nice to see an old spectrogram - it seems prehistory. 73 - Marco IK1ODO
Edgar, you are strong in JN35sa at 1200z on 137.700 73 - Marco IK1ODO that was my signal in dfcw60, tu for the reception from LA. i hope to work you soon on LF! Edgar DL2HRE in JO51tq
Congrats again to the traces at UA0AET. Now the step to UA0SNV is only a little farer. And maybe you even want to try to leave a trace in YV? :-) That would be 7692 km, but without the alps on the pa

And there is nothing about PLC, only the secondary service statement. Marco IK1ODO / AI4YF in most European countries the access to the 2200m band is based on CEPT/ERC Recommendation 62-01 E that sta
These receivers are now about 15 - 25 years old, so being realistic you will have to repair them from time to time. Having said that, the only thing I have had to do to mine is re-align the BFO VCO.

Marco: Thanks for the info about the Sellia Marina transmitter. Is this still operating? I thought that the Mediterranean chain had closed down. Hi Peter, that was about 10 years ago. Yes, it's all
Lessay and Sylt are quoted as 250kW, there are even powers for the western Chayka system ! Exact locations are also given. Also at a lot of locations you will receive signals from more than one stati
Hi all, If somebody scans it with a good resoultion (600dpi) I will gladly host it on my web server. Up to 100MB file is not a problem. That may be useful to many people, I think. Marco IK1ODO
Hi all, thanks to the excellent scanning job done by Jim Moritz the schematics of the Wandel&Goltermann SPM30 selective level meter are available. I uploaded the file to www.spin-it.com/download/SPM3
