Am Radio Transmitter Circuit. Have you ever wanted to listen to modern music or old time radio broadcasts on your vintage radio. Connect ground of the circuit to your earth connection for crystal radio testing or your water pipe.
Build an am radio transmitter. The am radio oscillator coil will give excellent stability. The frequency trimming can be done with vc2.
The schematic and bom show a 200µh inductor and a trimmer capacitor 150 500pf though these parts can be salvaged from an old am radio to preserve the directional nature of a tuning coil and an adjustment knob plate capacitor that work well for radio.
The am radio oscillator coil will give excellent stability. The published circuit diagrams of station qrp are for educational purposes only. These are offered for the furtherance of the readers knowledge regarding radio frequency design and principles. A small simple am receiver project with only 3 transistors.
