Going down a regenerative rabbit hole in search of a Quiet circuit

[jonovid]

before starting something that maybe a pointless exercise? do you know the answer to this? as I do not.
for most of us that can still remember, and are somewhat familiar with the single transistor 27MHz regenerative receivers used in toy  walkie talkies of the 1980s
and the extremely loud hissing when no in-coming signal was been received.
the question I have for the forum is this. can the current draw of a single transistor regenerative receiver determine its received signal strength?
assuming the regenerative circuit is stable. if so a squelch type of noise gate can be added to the regenerative circuit audio output by monitoring the regenerative supply voltage.

 the particular regenerative circuit schematic I had in mind was the VHF regenerative receiver in this video.
its simple to make and get going. as the base of any regenerative experiment.


and if by adding a experimental DIY squelch circuit it?
its not so Mach finding or designing a squelch noise gate design. but determining if a single transistor regenerative receiver changes its current draw based on received signal strength?
if yes , I am looking at a 2 or more transistor or op-amp schmitt trigger with a voltage reference circuit.  I can figure it out my myself.
and yes going down a regenerative rabbit hole in search of a quiet circuit that also adds to the component count.
if no! I have saved myself a pointless exercise and also by posting here others also.

update-
wrong forum thread..?  perhaps a completed circuit is needed before posting hypothetical questions

There's no reason not to add audio squelch.  Of course, it won't let you operate in CW mode.
Then CW is a minority interest these days.

There has been a resurgence interest in regen for wireless data systems.

www.cool386.com/arc/arc.html   Described here is a method for auto quench based on detection of excessive AF amplitude. It works like AGC. Instead of controlling the receiver gain it controls the magnitude of the quench oscillator injection. Worth experimenting with. (SA575 could do regen control and audio squelch).
