Been following the SW3 threads.
Way back when, perhaps around 1960 (I was in my teens), give or take, I
built an "FM broadcast tuner" that used a super-regen detector. I seem
to recall that the circuit came from a magazine of the day (Popular
Electronics?) and was basically a 1 tube circuit. I think it may have
used a 6C4 tube, but I don't remember for sure. Actually, 'my' version
used the 1 tube super-regen circuit from the article, followed by a two
stage audio amplifier to drive a speaker directly. While I had built
MANY HF and BCB receivers prior to this, this was my first venture into
the world of VHF, and it performed surprisingly well. We lived in Grass
Valley then, and I had no problem listening to the FM Broadcast stations
out of Sacramento. . .
Anyone recall the circuit and/or the magazine article this may have come
from?
