Selecting an FM antenna for use at a facility is much like choosing any other component: Some cost more than others, some are of higher quality than others, and some have different technical ...

The circuit was designed to operate a frequency modulation voice transmitter over the FM band 2 frequency range of VHF. Transmitter – an electronic device that can produce or amplify a carrier wave ...

This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor ...

[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which ...

The Si47xx series of integrated circuits from Silicon Labs is a fascinating series of consumer broadcast radio products, chips that apply SDR technologies to deliver a range of functions that were ...
