I was again tinkering with my superregen (a.k.a. Audioguru's "TOY" :lol: )
and I notice that nigel's information about the capacitor connected between the NPN's base and ground seems accurate.
I read that selectivity is supposed to suffer from incorrect <quench frequency>:<incoming frequency> ratio.
selectivity and bandwidth do relate to each other in opposite ways. wouldn't you agree?
I was wondering, could I calculate bandwidth based on the incoming frequency and the quench frequency?
if so, is there a simple equation for it?
Maybe this is the reason why I can pick up a TV signal when I adjust the quench oscillator capacitor to one value, and I can't pick up the same signal when I adjust the capacitor to another value.
