Where are you looking for JT65? It's not a "random QSO" mode like FT8 and FT4, but more of a special purpose weak signal mode like MAP65, JT9, FST4 and Q65, and the newer of those modes, FST4 and Q65, are likely to replace JT65 and JT9.

Hi Jim,

a minor correction to thee above, MAP65 is not a mode, it is another data communications application designed to take advantage of wide-band I/Q input (it also supports base band audio and UDP data from Linrad) and dual polarization aerial systems. It supports JT65 and Q65-60* modes, and is used for VHF and UHF EME where adaptive polarization can give significant decode sensitivity advantages.

Hi, I am running WSJT-X v2.4.0.  FT8, FT4 etc seem to decode and transmit fine.  JT65 mode does not seem to decode anything.  Any suggestions?  Thanks Rob W1AFP
