[Kenwood] low transmit on ssb

[Lawrence Jones]

I have a Kenwood TS850SAT. It has lost some of it's transmitting power 
on SSB. It does 100 watts on CW-FSK, FM-AM but not on LSB-USB. It will 
only do 50 watts on sideband.
The SSB power was at about 100 watts and started going down about a 
month ago. It seem to be holding at 50 watts.
I am writing this in hopes that someone may have information that may 
help me solve this problem. If you can help, please let me know.
