Lee McKusick was correct about many things, but of course we were a bit disappointed by his focus on store bought gear. But the 1971 Whole Earth catalog made up for this by publishing the schematic for a very simple single-triode receiver:

There is a follow-up article on grid leak detectors here:
Regen?
Right you are. It is so simple that I had assumed it to be a regenerative receiver, but on second look, it appears that it is not regenerative. I will change the title and the text. Thanks and 73 Bill
Per the Philco TechRep Training manual 1953, it’s the “Grid-Leak Detector(Fig 5.1c)”. The text says “The grid-leak detector was formerly employed extensively in regenerative detectors, but now is used only in special applications”. I guess with a little feedback, why not? That manual was the “Art of Electronics” of its day. My uncle John used it overseas, in the Air Force.
If it had a tickler coil! If you poke around on this web-site I have some regen circuits and ideas.
