audioguru Posted September 5, 2006 Report Share Posted September 5, 2006 Hi Sssaaa,The circuit you posted uses a crystal in an odd oscillator circuit. Since a crystal cannot be frequency modulated very much then the transmitter must be narrow-band for a ham radio receiver. It also doesn't have pre-emphasis like radio station FM transmitters use.250mW is probably its input power, not its output power. Quote Link to comment Share on other sites More sharing options...
