Micro Power FM Circuits
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.
