I feel that I understand something when I can explain it to

one thing I have yet to understand is the purpose of the quenching
action in superregeneration, apart from thequenching itself.

How does the quenching of an oscillating stage yield a detector
that works for AM, FM and / or SSB, when the quenching frequency
is supersonic, and neither at the RF nor the AF frequencies?



The quench kills the gain cyclically, allowing the RF stage gain to
build up again until the next quench. The result is that the RF, quench
and AF frequencies are all present at the output of what is essentially
a self-oscillating mixer.

But what does the quench DO? What it its purpose? Why not just let
the oscillator run for the self-oscillating mix?

Well the point is that if you let the oscillation build up
sufficiently then the gain becomes so high (super regens are designed
to have massive static gain in the RF stage but high Q feedback means
that it takes time to ramp up) that the output limits and the audio
spectrum you're looking for is no longer present, there is just the RF
frequency rail to rail.

OK, now I understand.

The purpose of the quench is to keep an over-excited stage item calm and
usable.

How does one quench M3OSN?
