Hello David,


congrats on the TA QSO and I am happy that SlowJT9 was helpful.

The advantage of multiple deco= nding will be under marginal conditions (SNR of -26dB or less), although occasionnaly up to -20dB a non zero DT decode might pop up.

The decoded signals can be found in the file "decoded.txt" in = the subfolder "extra" (relative to the folder where you inst= alled SlowJT9).

I would appreciate it if you could wend me the file as it will help me t= o figure out how multiple decoding behaves in the "real world", w= hat might be useful for further improvement of SlowJT9.


73, Rik  ON7YD - OR7T

I was very pleased this evening 06/March/19 to complete a JT9-1 QSO wi= th Paul N1BUG on 137kHz.
Paul and I have been trying almost nightly for the past 3 weeks overco= ming many problems along the way.
Finally we succeeded, with reports of -21 for me, while N1BUG was -27 = in IO91FR (4842km)
I should also like to say thanks to Rik ON7YD.  A few days ago I = downloaded SlowJT9 v0.9.16.0.  I ran this, with "multiple decodes= " switched on and had WSJT-X running parallel.
During the 12 minute QSO, SlowJT9 decoded 5 sequences from Paul at -27 whil= e WSJT-X missed 2 of the 5. Both programmes reported the same signal levels= . Audio for transmit was taken from WSJT.
- Rik. I have saved the decoded files as you requested. when I find out whe= re they are, I will forward them to you.

Since making a crossband TA QSO (137k to 14MHz) in Sept 2000, a 2-way = QSO has been a long term ambition. This is one ticked off the bucket list. = Thanks Paul for the dedication and perseverance.
