Vest Pocket VHF FM Test Generator
(Summer Circuits 2010 article)
After licensing restrictions were relaxed in many countries for VHF FM band transmitters with 50 nW transmit power, several small, inexpensive FM transmitter modules appeared on the market. In the author’s view, such a module forms a good basis for a small FM-band test generator. This only requires a sine-wave modulation signal, which can come from an existing audio generator.
