Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

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.

Here are some DIY FM Transmitter circuits that we have been published on electroschematics.com. This do-it-yourself fm transmitters are pretty easy to build and will give you a good feeling when ...

Graphene has attracted much interest as a future channel material in radio frequency electronics because of its superior electrical properties. Fabrication of a graphene integrated circuit without ...

Testing FM receivers is not that much different than testing other pieces of audio equipment. Appropriate tests include the big six: level, frequency response, THD+N, phase, interchannel crosstalk, ...
