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?
