AM DSB Transmitter for Hams - circuit diagram of simple double side band suppressed carrier (DSBSC) transmitter for hams. Circuit uses crystal oscillator, crystal can be switched for multi band operation. . (added 9/04)

AM Transmitter (Andy Collinson) - The circuit is in two halfs, an audio amplifier and an RF oscillator. The oscillator is built around Q1 and associated components. The tank circuit L1 and VC1 is tunable from about 500kHz to 1600KHz...(design added 8/03)

Automicro TM02 high power transmitter module schematic - ….(electronic schematic added 04/09)

Micro Power AM BroADCast Transmitter - In this circuit, a 74HC14 hex Schmitt trigger inverter is used as a square wave oscillator to drive a small signal transistor in a Class C amplifier configuration. The oscillator frequency can be either fixed by a crystal or made adjustable (VFO) with a capacitor/resistor combination. (added 4/02)
