Simple shortwave receiver circuit
WebbAs simple as this circuit is, it puts out a very clean signal and I can not detect any harmonics or "birdies" that are so common in other transistor oscillators. I have used this very circuit in my S-120 and my 1936 Fairbanks Morse short wave home receiver and it works splendidly in all of them, opening up single side band broadcasts that were once … Webb22 jan. 2014 · The diagram below shows the circuit diagram of this radio, drawn by reference to the circuit board itself. All the components are from scrap. Starting at the left of the photograph, you can see two small coils on formers. One has 9 turns, the other 6. They both have a ferrite slug which I adjusted to get different frequency ranges.
