Another question---can you check if the distortion is also on the Aux input
as well? If it is not, that narrows down the problem quite a bit.

A couple of questions:
--Have you tried a Master Reset?
Yes, I have performed master resets following firmware updates. The TX
audio issue has been with me since day 1.
--Can you hear the raspy sound in the monitor?
Yes, I can hear it in the monitor. Doesn't matter what user setting I have
nor the type of microphone. TX into antenna same as TX into a dummy load.
--Can you hear the raspy sound in another receiver?
Yes, another receiver sounds same as the monitor. Audio is
intelligible.........just not world class.
--What happens if you turn down the mic level control to the point where
the ALC light is not flashing?
On-air reports indicate some improvement when gain is reduced to low level
(35). The improvement is not, however, significant.
--What power supply voltage are you running and how much does it dip at
the rig connector under key-down, full power?
I am using the TT 22A continuous supply. I have no voltage monitor
connected.
I heard another O2 user over the weekend who's audio sounded distorted,
but since I was just getting ready to leave the house I didn't have a
chance to talk to him. If I run into him again (he's usually around on 75
at night) I'll see if I can get an idea about what might be causing his
problem, and report it back here.
Please do. I think there are more of us out there. I am starting to think
that there may be a hardware problem with the audio board.

I have received reports of a raspy edge on all voice peaks. The problem
does not appear to be RFI related nor is it affected by TX EQ or LF
roll-off settings or the type of microphone used (condenser mike or heil
GM-5). I know of one other O2 owner that has experienced the same
problem.
His is at the factory for troubleshooting. Are there others?
