 QRP AM(cw) Transmitter
for the 12 meterband by ON6MU
In this project, you will make a simple low-power broadcast-type circuit, using a crystal oscillator integrated circuit and an a collector modulated AM oscillator. You can connect the circuit to the an amplified microphone (no amplified microphone has a to low output voltage to work. at least 100...200mv is needed).
