The circuit exemplifies the use of ZN414 IC to produce a handy AM radio receiver. ZN414 IC– a composition of transistor tuned radio frequency (TRF) circuit packaged in a 3-pin TO-92 plastic package ...

A small, simple AM receiver project with only 3 transistors. This circuit can pick up medium wave stations in your area. It can use general purpose transistors, and in this example there are 3 BC109C ...

Discover a clever 1970s AM radio design that tunes MW and LW without a single coil. This vintage synchrodyne receiver uses a synchronized oscillator for surprisingly sensitive, high-quality reception ...

Abstract: The DCF77 signal is used to carry out the information of precise time for long distances. Standard DCF77 receivers consist of AM long wave receiver circuit, connected to a data processing ...
