1.     XF-8,9HC CW filter installation and alignment

Measurement equipment used: Universal counter (50Mhz.)

First of all, I have done all the steps from service manual:

Next step: CW/FSK Carrier Point Alignment. I tried to follow the service manual….

OOPS !!!

I couldn’t find TP5003 on the IF Unit. After I have studied the diagrams, I saw the mistake. So, connect the frequency counter to TP5001 on AF Unit, and all the rest it is OK….

Another step: IF WIDTH ALIGNMENT, like in manual



And now, ladies and gentlemen, the results !!!


FT107M – SSB


FT107M – CW


FT107M – FSK
