Simple regen RX

On my main website is the circuit of a very simple regen RX. I think mine was on 40m, but the same idea would work on most LF and MF bands. At higher frequencies the drift might be excessive. It is hard to make something simpler that will hear as much.

I seem to recall the late G3RJV (SK) referring to this in a PW magazine column some years ago.

There is a bigger schematic on the website. Click it and the image is bigger.
