[Kenwood] no audio

[n3drk]

My kenwood 930s has performed great but i have not used ssb for the past
month or so. I have been on cw and when i tried ssb this morning i have
maybe 20 watts output on peak. Switching to cw i have full power output.
Now, on ssb the mic gain control along with the driver are at maximum
gain.Still very very low output. I switched mikes and the same problem.

Anyone have any ideas on what is happening or what i could check? Judging
from the past it is something simple i am overlooking.

thanks
john
