Andy, thanks. I just decoded Gary : "CQ G4WGT IO83", sync = 11 , dB = -2. Not sure wether QRM is an issue, I see 2 bright traces against a black background. What else could cause the poor sync ? 73,

That sync figure  not 'poor'.  The mode will decode with values as low as 3 or 4.  Just not as good as it could be in pure noise at that S/N.   Pulse type QRM interferes with the decoding process mor

Gary, Jim, thank you both for the JT4A test. Gary, I got no further than a single decode, all others went to Jim ;-) I must indeed read the manual (although reading a manual can be seen as a sign of

Hello Gary, Jim, I just fired up WSJT7 in JT4A mode. I can see a very fat trace at 503.460 that decodes as "TEST M0BMU" and a little less fat trace at 503.600 that is probably Gary. But even if I set
