Kenwood TS-430S Repair and Restoration. November 2018

This is a repair and restoration journey of the classic Kenwood TS-430S HF transceiver. The TS-430S is an iconic HF transceiver from the mid-1980s and despite this particular radio having had several owners it was in moderately good condition with all knobs and marking intact. The radio has in recent times developed various issues in both receive and transmit functions that had left the radio completely useless, these are common problems not only with this model, but with many similar models from the same era. The radio is slow to start up and stabilize and there is an unstable tone present in the receive audio. The radio receiver has developed low too very low sensitivity on most of the band pass filter groups, the transmitter has intermittent variations in power level and the VFO is unstable. Following a comprehensive restoration and repair project the radio has had all operation faults successfully repaired, including some general maintenance and a good clean up resulting in a radio that feels as if new and is a pressure to operate.
