​Hello Andy,


SlowJT9 does use the WSJT-X decoding engine (JT9.EXE).

JT9-2, JT9-5 and JT9-10 are resampled to JT9-1 and send to the JT9 decod= er.

In the resampling process frequenties are multiplied:

- by 2.222 (15360/6912) for JT9-2

- by 5.926 (40960/6912) for JT9-5

- by 12 (82944/6912) for JT9-10

The maximum frequency the JT decoder can handle is 5kHz, so for JT9-2 th= e Fmax is reduced to 2250Hz for JT9-2, 843Hz for JT9-5 and 416Hz for JT9-10= .

The lowest frequency for the JT9 decoder is given as 200Hz, bu= t it is my experience that is also decodes well below 200Hz, so in practice= the lowest frequency will be whatever is he low audio bandwidth limit for = TX and RX (I would suggest to stay above 200Hz, maybe even 300Hz).


73, Rik  ON7YD - OR7T

A question about the JT9-Slow S/W
Does it decode all transmissions within a certain band, as WSJT-X does?
Or just one at a time?  In which case how far off can the tuning be?

I have my Elad FDM Duo tuned and feeding the software, Rx Freq set to 405, = but no decodes as yet
