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

Uploaded June 2016 | Updated September 2026, 2 weeks ago

This video documents the troubleshooting process I went through to repair a Yaesu FT-817ND QRP all-mode HF/VHF/UHF transceiver. 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. The video documents the troubleshooting process, but does not show the bench work (scope and DMM measurements). 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:
