Thread-topic: LF: SlowJT9 v0.9.02

Hello Eric,


yes, a scale factor of 2 and 5 is used.

I hadn't any information about the old JT9-2 and JT9-5 modes and those scale factors seemed the most straightforward to me and make the conversion to JT9 easy.

SlowJT9 won't run in Wine in Linux, nothing particularly useful was output on the command-line.  I tried using an old version of WSJTX (0.95 r 3278) but seems there is some protocol incompatibility.

The original JT9 submodes specs give:

Symbol Length:

JT9-1 0.58s
JT9-2 1.28s
JT9-5 3.41s

Is your program using a 2x and 5x scale factor for JT9-2 and JT9-5 respectively?  If that is the case, the symbol lengths will be different than the original specs and old versions of WSJTX will not be compatible.
