Another Thermatron Receiver (video)



Thanks to Steve N8NM for sending this along.   He said it seems to be crying out for a synthesized VFO -- I disagree,of course. 

I like the filter arrangement -- one crystal at 455 kHz,  two tune-able IF cans and a phasing control.  This seems like a good way to get both AM selectivity (broad) while still having the ability to narrow the bandpass for SSB. 

The builder did a great job. Does anyone know who he is?
