I feel that I understand something when I can explain it to
a rank amateur such that they will also understand it, but 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?


Everything I wanted to know, and more besides ...

Thanks, BrianM, but google never occurred to me. But perhaps it is
always best to attempt technical discussion in the NG to encourage
newcomers, even though M3OSN will attempt to stifle such dissemination
of information?

Well, it doesn't fit in very well with the policy of discouraging
homebrew. If someone builds a regenerative rx, it is depriving the rig
sellers of trade. In turn, the advertising revenue falls - leading more
retailers to seek advertising opportunities elsewhere.

So while we see this as wrong, it is all in a day's work for the great
and good. From a commercial perspective, I can see their point.
