[CQ-Contest] ft-990 Keyer Troubles

[J. Parke Allen]

All,

 

I have effected temporary repairs by bypassing the bad keyer chip and was
able to do just a few contacts in WWCW to test the rig.

 

A replacement chip or keyer circuit board is still needed, so if anyone
finds a source for the FT-990 SW-A card or even just the keyer chip, please
let me know.

 

Thanks,
