Want to know how to interface an Arduino with a Radio Control Transmitter? Read on to see how. Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

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, ...
