This is a simple crystal controled regenerative detector that I have developed over the years and is capable of USB only detection (no beat in the LSB) depended on the setting of the potentiometer.
The sensitivity is low without a preamplifier. But for a 1 transistor challenge, I would like to apply reflexion to it (feed back the audio from the source to somewhere).
Any ideas of how can I do this?
There may be some kind of rectification (diodes) and the rectified AF to be fed back to the Gate? Then take the output from the drain?
