[GreatScott] does exactly this in the video after the break, building both a transmitter and receiver ... as [GreatScott] built a basic circuit around a TA7642 AM amplifier/demodulator IC ...

While most regenerative receivers are designed for AM broadcasts ... most advanced receiver ever conceived, and it certainly isn’t the most sensitive. But it’s one of those circuits that ...

Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator generates a signal 455 kHz less than the frequency of the ...
