[hpsdr] Pentalope audio

I found a couple of things that affect the transmit audio. First I modify  
initozy11.bat
for "no mic boost". There is PLENTY of mic gain available on Penelope.  
Another
thing I noticed is that even with all transmit audio gain controls at zero,  
I still have
mic audio, but not much. Third, in regard to the crackling you hear, go to  
SETUP>
DSP>AGC/ALC and turn off the Leveler (uncheck it). 
 
Good luck,

There seems to be a high noise level in the pentalope audio system.  In 
L/USB, AM modes and no mic plugged in, the TX Mic meter reads in the  
range of -20 to -25db when PSDR MOX is keyed.  With MON on, the noise  
sounds like a mix of crackling white noise and unstable audio tones.   
Enabling the audio gate kills the noise as does enabling VAC.    The 
noise is present on the external TX RF output meter about 25-30 db  below 
peak output and is visable on then TX Panadaptor.

The noise  reminds me a bit of noises that in past time I traced to bad 
solder joints  or over stressed/reversed polarized capacitors.

Does/has anyone else  seen this characteristic ?    Is there some setup 
that I have  missed ?
