The real radio is exactly in the middle of the photo, even though it's hard to believe.
3.1 Simple super regenerative radio that works by default.
And if you do not know at a first glance how this works, then comments (that may be useful) will follow.
It
works and has been tested many times. All the data needed to make such a
radio are on a schematic diagram. Be sure that ะก6 is 6.8pF to 8.2pF (for 2N3904), and all voltages coincide with those indicated. If you want, you can go to the next
page, which tells you what you can count on with such a radio.
