This circuit is essentially an amplified crystal set. The inductor could be a standard AM radio ferrite rod antenna while the tuning capacitor is a variable plastic dielectric gang, intended for small ...

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 ...

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building both ...

A simple v.h.f. f.m. receiver chassis is described with a view to showing that it is possible to employ quite simple circuits and cheap components and construction and yet abstain satisfactory ...
