Re my Posts about a year ago about this radio .... Hammarlund HQ 100A Comms Receiver

Eventually got back to it recently and today it is "comms' ing" with me .... Smile

Has been a much bigger job than expected ..... eg both power and audio transformers were 'chewed' and required surgery, wires chewed, some tinkering by others, had to rebuild power supply etc ..... but most functions are working. Some distortion to locate and will need calibration etc.. Crystal calibrator and clock are isolated for the moment.

Thanks to those who provided me with information and web sites for Manuals etc..

One of the good things with Comms receivers is that you can still get WWV &WWVH and use them backwards, if there is no other way to heterodyne (Zero beat) against to get the calibrator on frequency.

Amazing what damage you can find when the little animals have ratted it. Depending what it is on, Soda Ash & a bit of dishwashing liquid removes Mouse doo. Never get it on, or put it on, a Bakelite cabinet.
