Hi Breton, I am facing a problem on audio. I have a kind of QRM and it seems that audio output lost its power. By the way frojm you video I am not able to understand if you are fixing the same problem. Thanks

I have the 450s and on the lowest setting on FM the power is around 8 watts . Can you tell me which pot will turn the FM output down to around 4 watts on its lowest setting Many thanks Andy

Were can I find if unit for Kenwood ts450s
@davidtimm567 2 years ago

The PCB under my C104 was dissolved, or otherwise stripped, down to copper, so I replaced C104 even though it was within spec. I still have low power on TX. I removed and tested C99 and C101 as well, and they're within spec. Is there another common cause of low (10 or less wattage) output on a TS-450S besides C104, C99, or C101 leaking?

@graniteridgegreens6278 2 years ago

What is that caps capacitance? and the other two larger ones? I have a audio output problem where it blanks out the audio output, same if you put too much audio into it. Thanks, No Sign.

İ Have low audio problem.it is Due to c104 too??
@ironhead320 2 years ago

Would that also cause low audio output locals tell me I sound like I'm far.away
@stevewinwood3674 4 years ago

so if you have loads of output on pin 4 is that correct or incorrect?

Can anybody tell me how to adjust the HF for am stations, I own a Kenwood TS-140s, When I use my scanner, am is fine, but the Kenwood will pickup the am stations. Thanks

Ciao Breton, volevo chiederti se conosci un software per gestire un kenwood TS690 SAT. Puoi darmi qualche notizia, ti ringrazio e ti saluto Alfredo IU0NIB
