About the crackle noise problem - -
Dudley asked for an audio file of this, and I have sent it. I'm waiting
for his response.
I did lower the audio levels on the mixer from 100 to 70 and below, but
this didn't resolve anything.
I also lowered the AGC setting to 70 and below, but this didn't resolve
it either.
Are there any other settings I should be adjusting?
The crackle noise I'm most concerned about appears with strong signals
that should be received very clearly. The .wav file I sent to Dudley
should show this.
I need more info on the buffer size you are suggesting. It seems to me
that any of the settings listed in Power SDR should work.

Yep! Usually increasing the buffers works.

This may be obvious, but reduce all your audio levels from 100 down to say
70 - I had the same crackle that was annoying as hell. Reduced my levels
down from 100 -, no more crackle! The other thing possibly increase the
buffers?

Dudley,
I'm getting a crackle noise along with the audio from my radio. It
seems to run with the level of the audio and is particularly noticeable
with signals that are otherwise clear.
At first I thought it was local interference or maybe related to the
powered speakers. But it is present with headphones as well as
speakers. It doesn't appear to be from local RF interference, either.
It's a little elusive to try to describe. Trying to listen to strong
signals on sideband does become fatiguing with the high pitched crackle.
