#240: Repair of Yaesu FT-817 with SSB CW AM Transmit Problem | QRP Rig

The problem was that the unit would not transmit on SSB, AM or CW modes of operation. Transmit on FM, Digital and Packet were fine on all bands, and receive functionality was fine on all bands and modes.

This repair wouldn’t have been possible without the great information from Clint, KA7OEI, and the fantastic information available on his FT-817 resource pages:
