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 (circuitdb): circuit is deliberately limited in power output but will provide amplitude modulation (AM) of voice over the medium wave band. The circuit is in two halfs, an audio amplifier and an RF oscillator. (added 2/07)

AM Transmitter (zen22142): (design added 8/03)

AM Transmitter (zen22142): (electronic circuit added 4/05)

AN-512: DS8911 AM/FM/TV Sound Up-Conversion Frequency Synthesizer: National Semiconductor Application Note (app note added 6/06)

DS8911 AM/FM/TV Sound Up-Conversion Frequency Synthesizer: National Semiconductor Application Note (app note added 6/06)

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)
