Hello Paul, currently you have to subtract 3dB for JT9-2 and 7dB for JT9-5 to get the "true" SNR. A new version of SlowJT9, with correct reports and the cycle bug fixed, will be uploaded later today.
Paul, all, before I started programming SlowJT9 I did a "dry test" by generating JT9(-1) and JT9-2 WAV files with a known SNR and feeding these to the JT9 decoder of the WSJT-X suite (the JT9-2 WAV f
Hello Rik, v0.9.02 installed and monitoring 630m JT9-2 here. Yes of course. The drift I measured was the actual RF drift of the signal, measured visually with a high resolution waterfall external to
Hello Paul, decoder.txt seems OK. I am sorry if I gave the impression that I thought you were complaining. Certainly not, all reports on crashes are abnormal behaviour are welcome. But these rare cra

Hello Antionio, the signal just above 1200Hz is most likely WSPR (by counting pixels I estimate its length at 110 seconds, a JT9-2 transmissions takes only 98 seconds). Either someone transmitting ou
