FT221R no ssb or cw ?

Postby Steve- GW7VFJ » Fri Jun 30, 2017 4:23 pm

Hi Folks,
I have had a 221r for quite a long time but its been sitting on a shelf. Thought i'd give it a run up but it s developed a fault.

It works fine on FM and AM but no receive on SSB or CW. It has a Mutek front end. The crystal marker will work on am and fm but doesn't generate a signal on SSB or CW.

The obvious choice was the band selector switch. I have given this copious amounts of switch cleaner but no joy. All the board edges have been cleaned and reseated.

I wonder if anyone has come across this fault previously and could point in the right direction. Providing the mode switched is ok something maybe a miss on the SSB if board maybe ?
Thanks in advance
