I just found out something interesting.
I played with my superregen, mainly with the base bias resistor and the pull-down capacitor that connects to it.
I find that when R is between 82K and 140K, and C is 150pF, I am able to pick up my local TV station fairly well with an antenna :wink: , even though reception in my room sucks :cry: .
and when I was calculating the approximate frequency using R and C, using 1/(R*C), one of the values was actually 75Khz, which is the bandwidth of the TV audio signal (according to what one of you have said).
so I think my circuit and my calculator answered my question.
