Hello Andy,


the "power level" slider (at the right) is initially set to ze= ro. Maybe that is the reason for no audio.

I agree that this is confusing, but I have done this for safety reasons = (I don't want have any transmitter "blown" because of a too high = audio level).

I just tried installing this 0.9.10 version  on my Dell Inspiron lapto= p Win-10.  I set the soundcard correctly to  "Speakers / Hea= dphones" and Tx tone to 1200Hz ,  hit enable Tx then  the 'T= une' button.   It shows as transmitting but there's no audio tone= .     WSJT-X and other datacomms packages are working fine, both be= fore and after trying

Normally don't get any issues like this with the default (the only) soundca= rd present.

I'll test on my other two PCs,  an HP Desktop with Win 7 and HP Notebo= ok

On a different matter, I'll be writing this up in the next RadCom "Dat= a" column (February's)   Could you summarise the baud rates = and frequency shifts finally settled.   There has been so much di= scussion and changes I lost track and haven't followed the latest version

Dear all,


I just uploaded a now beta-release of SlowJT9 (v0.9.10).

The changes are


- JT9-2 and JT9-5 parameters changed to the original ones. The slightly s= lower baudrates make better advance of the transmission cycle. In theory th= is should improve S/N by 0.46 dB for JT9-2 and 0.74 dB for JT9-5.

Be aware that due to the baudrate changes there is NO BACKWARD COMPATIB= ILITY for JT9-2 and JT9-5. 
In other words: JT9-2 and JT9-5 send with v0.9.10 cannot be decode= d with prior versions (v0.9.00 - v0.9.03) and vice versa.

The JT9-1 mode however is still the same and can be sent = / received with all versions (and is WSJT-X compatible).


- JT9-10 mode (10 minute cycle) added, for the fearless.

Therefore all test reports, remarks, suggestions and opinions&nb= sp;are most welcome.

For the same reason no other changes are applied.

For now only a Windows version of SlowJT9 is available. But as= the used IDE has cross platform facilities it should be possible to suppor= t other operating systems as well in the future.
