Riho,

Joe K1RQG and I had a similar issue with audio levels and Joe pointed  
out to me that if you modify the initozy11.bat file (e.g.,  in  
Notepad) so that the lines for Ozy and Penny that formerly read

writeI2C 0xfffe 0x7 0x1a 0x2 0x08 0x15
and
writeI2C oxfffe 0x7 0x1b 0x2 0x08 0x15

read instead

writeI2C oxfffe 0x7 0x1a 0x2 0x08 0x14
and
writeI2C oxfffe 0x7 0x1b 0x2 0x08 0x14

the audio gain is scaled much better and there is no overamplification  
nor distortion apparent.  With the front panel audio gain in PowerSDR  
set at about 20 the levels seem to be just fine!   Nice quality TX  
audio.

Give it a try!  It'll probably fix you up.
