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 - 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.… [Andy Collison]
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)
