Elektor community members have always loved audio projects. This Mini VHF FM Receiver project from 2009 presented a complete receiver circuit that boasted excellent reception and sound quality. Let’s ...

Building an electronic gadget from a kit is fun, but what once it is assembled? For many electronics enthusiasts, the real fun only begins when you can mod it. In this article, we present a cheap FM ...

The project is a user-friendly and cheap FM radio receiver which produces the desired audio signals using integrated circuit to achieve the pre-processing units. During operation, the user is allowed ...

This is a simple FM Radio Receiver that is built around a single IC1 AN7236 (18-pin), a single HF transistor Q1( BF 494) and a few external components. This FM radio can be tuned for frequencies ...

This is a simple FM radio using a popular TBA120S (14-pin). Most FM radio works on 10.7MHz IF frequency but this one does work on 5.5MHz IF frequency. So, the components like the 5.5MHz ceramic filter ...

This inexpensive FM radio receiver antenna booster uses the BF324 TO92 style pnp transistor in a grounded-base configuration. The circuit may be used as a signal booster with VHF receivers whose front ...

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.

With the portable Li-Ion battery powered FM radio receiver you can listen to your favourite radio station. This device is equipped with cost-effective components, including a CH32V003J4M6 32-bit ...

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, ...
