​​Hi Paul,


you discovered another but !!!

As mentioned before the max audio limit was set to 1400Hz (to avoid coll= isions with WSPR). This was done by setting the decoders max. fre= quency parameter to 1400Hz for JT9-1 and 2800Hz for JT9-2. But si= nce the JT9-2/JT9-1 ratio now is 2.2222 the max. frequency  parameter should be 1400*2.2222 =3D3111Hz.

Since that isn't done (it's still 2800Hz in version 0.9.10) the max= imum JT9-2 frequency is 2800/2.2222 =3D 1260hZ for now.

This will be fixed in the next release of SlowJT9.


73, Rik  ON7YD - OR7T

Update: It seems the new AF limit for JT9-2 is somewhere between
1250 and 1300 Hz. 1250 decodes, 1300 does not.

This may explain why my JT9-10 test did not work. It may not be
possible to get low enough AF for decoding without being below the
SlowJT9 minimum AF.

73,
Paul
