Andy,

The present version of SlowJT9 has a limit of 843 Hz audio frequency
for JT9-5. JT9-10 when implemented may have a 419 Hz limit.

During recent tests, some preferred to transmit around 136.6 to
136.85 to allow receiving stations to leave receivers on 136.000 and
still monitor other modes along with JT9-5. Others could not do that
and operated JT9-5 around 137.3 to 137.4.

If Rik is able to remove the audio frequency limitations I expect
this split to disappear with everyone preferring to be in the 137.3
to 137.4 area.

73,
Paul N1BUG
