My WSJTX has CALL3.txt - with six calls in it, none of which I have worked. I have an earlier implementation WSJT6 from 2007, and the CALL3.txt file there is quite large. However, my own callsign is not in it, and I've been active on WSJT modes for quite a while, particularly the meteor scatter modes. There are people who consider anything copied by computer rather than by ear to be cheating. That would also wipe out PSK31 and a host of other digital modes that can be copied below the noise. I've been having fun with JT65 and JT9 on 6 meters. There are a lot more openings there than we think, and the JT modes hear signals I can't hear with my ears.
