[Electrothaumaturgist]

As a slight addendum to the FM discussion, the 1942 Philco 42-400 that I restored a few years ago had the old-style FM circuit. I was able to attune the circuit to receive the full range of the modern frequencies, apparently compressing the signal to fit into the spectrum, then spreading it over the bandwidth, so it actually tracked quite nicely up and down the scale and received all the stations as far as I could tell- as many as my modern FM test radio I had there. The FM scale wasn't so precisely marked upon the dialface, so it was close enough, and the FM sounded marvelous! I think Ron attributed that PHenomenon to some kind of oblique harmonic resonance signal that it was picking up. However the method, it worked! I guess when you spend about 100 hours or so aligning it up by ear, you're bound to stumble upon a big surprise. Or was it just lady luck there smiling? It was almost surreal hearing grunge rock blasting out of that beautiful console!
