This is a simple 27MHz FM-CB receiver circuit built with TCA440 for listening CB ( citizen’s band ) transmissions with FM (frequency modulation). The selection is made with ceramic filters. This 27 ...

[gpsKlaus] built this little FM radio (translated) based on the AR1010 IC. That chip is controlled via I2C by an ATtiny45 microcontroller. His tuning implementation relies on presetting 16 stations in ...

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 ...

The variable capacitor C1 and L1 will constitute the tank circuit which will produce the high frequency signal, the capacitor C1 is variable so that we can produce different frequency signal by ...

In the video below, the process of making this simple radio FM transmitter is explained in details. The project starts with wiring the mono phone plug to an audio source like an mp3 player. Once ...

Sinclair Broadcast Group, which in the past has expressed concern about the performance of DTV receivers, last week announced that informal tests of fifth-generation prototype receivers reveal ...
