Radio Repair & Restoration Group

The Radio Repair and Restoration Group came about in 2020. As needed repairs to existing club radio
equipment became more involved, it was necessary to recruit additional talent to repair both historic radios from the clubs past and radios donated to the club. Not unexpected, some radios required little effort to restore while others were much more complex.


Instruction and practice in soldering are offered.
