The Digital Radio Consortium came to the IBC Show in Amsterdam eager to announce several new developments related to the DRM ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have, for the first time, used a semiconductor laser to send and receive radio signals. The hybrid ...

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building both ...

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, ...

Article 810 provides installation requirements for transmitter and receiver equipment as well as the associated wiring and cabling (Fig. 1). Article 810 applies to: VHF/UHF antennas, which receive ...

Why does a spark produce radio waves? Air normally does not conduct electricity. However, if the voltage is high enough (for a given amount of air) the electrical energy causes the air atoms and ...
