Hi Stefan, LF!

> Will someone transmit on LF over the weekend?

Alexander R7NT informed on rus forum 136.su - he started JT9-10 on 136.405 kHz 
using last version  0.9.14.0

>> Beta-release v0.9.14.0 of SlowJT9 has been uploaded, see

>> Changes:
>> -JT9-10 mode added.

>> - Lower frequency limit dropped to 200 Hz (was 400 Hz).
>> - Option to discard the audio frequency limits added (Settings -> Mode).
>> In that case the TX boundaries will be 100 - 4980 Hz regardless of the JT9

>> The RX boundaries however will still be limited by the resampling process:
>> JT9-1: 100 - 4980 Hz
>> JT9-2: 100 - 2240 Hz
>> JT9-5: 100 - 840 Hz
>> JT9-10: 100 - 415 Hz
>> - Non fatal bug fixed that skipped PTT handling in the first TX cycle after 
>> 'Halt TX' was pressed.

>> Bug reports, remarks and suggestions are welcome.
