Micro Power FM Broadcasting

Posted on Jul 13, 2012

Here are some utility circuits for use with the Ramsey FM10a, and other small FM stereo transmitter kits. This information may be helpful for setting up a micro powered FM radio station. The FM10a and similar kits tend to put out a low quality, broad band output signal. This is not a big problem with a 5-10 milliwatt signal, but amplifying the output of such kits beyond 50mw is a bad idea, as the amplified signal can cause interference with other radio services, drawing unwanted attention to your hobby station.

If you want to work with a higher power transmitter, find a better quality transmitter such as the Free Radio Berkeley Mono PLL kit, and build my circuit for an FM Stereo generator (above).
