I fear that you will be incorrect and confusing regeneration and

I almost missed it. No, he's talking about a superhet with standard
455Khz IF, where some feedback was added around an IF stage (usually a
"gimmick" capacitor so one can adjust it), and with control of the
cathode, one could increase selectivity and put it into oscillation so
there was something to beat against the incoming signals to demodulate CW
and SSB. But that's really just a more complicated method of regeneration
and superregeneration.


He is discussing a regenerative IF detector, but not a superregenerative one
where the feedback is increased well past the point of oscillation to give
very high gain. There would not have been a quenching oscillator in what
he described.

The quencher acts like a balanced modulator onto the oscillatory stage to
remove the presence of the on-channel carrier out to two sidebands distanced
away by the quench frequency, which is why the super-regenerative technique
does not resolve SSB and CW.
