This AM receiver circuit is based ob the IC ZN415 introduced by Ferranti. This IC is an improved version of the early ZN414. It is a complete AM radio receiver and does not need IF transformers and ...

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 staple of starting off in electronics ion years past was the crystal set radio, an extremely simple AM radio receiver with little more than a tuned circuit and a point contact diode as its ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive.
