Kenwood TS-450s

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. -- Yorklynyankee Having same problem with my 450. Did you find the problem? Colin... |

Kenwood TS-450s
My 450 starts sending Morse code letters U & L as soon as I power it up master reset does not fix the problem and the only time it will stop is momentarily when I change frequencies then it starts back up again. Has anyone encountered this problem and can anyone point me in the right direction to troubleshoot it? Thank you Sam in Colorado. N0KEI
