Thank all of you for your suggestions. Just for the record, I don't
operate CB radio, I am a retired Research & Development electrical
engineer from HP, and I have a masters degree in Electrical
Engineering.... now to answer some of the questions. As I mentioned in
my first posting the radio is connected to a 50 dummy load. By low
output power I mean 5~10 watts, I have tried two different microphones.
I have another Kenwood TS-450 so I have a working radio to compare their
outputs. When I whistle into the radio using USB/LSB on any bands at any
frequency, the radio will only put out 5~10 watts. Whereas under
identical conditions the working radio will put out 100 watts. There is
absolutely NO DOUBT that this radio's USB/LSB is not working. The same
radio puts out 100+ watts on CW and FSK. I suspect something in the
balanced modulator, but I am looking for someone who has encountered a
problem like this before. This radio is known for having some common
problems, like C104, so I was hoping that there was another frequently
failed component that causes this problem.
