AM Transmitter circuits

Posted on Feb 7, 2014

The AM Transmitter circuits in two and a half, audio amplifier and an RF oscillator. The oscillator is built around Q1 and associated components. Tank circuit L1 and VC1 is melodious from about 500kHz to 1600KHz. These components can be used from an old MW radio, if available. Needs Q1 regenerative feedback to oscillate and this is achieved by connecting the base and collector of Q1 to the opposite end of the tank circuit
