Am Transmitter Circuit. Connect a 3 meter antenna to the middle pin of the coil. Although the schematic looks somewhat complex the.
You will love this. The inductance used in the tuned circuit in the modulator is 49 7 mh. A small simple am receiver project with only 3 transistors.
The oscillator is built around q1 and associated components.
Place your am crystal radio close to the transmitter and tune to the frequency of the transmitter 1000khz. The picture to the left is a high quality radio transmitter for the a m. This is the simple and low cost am transmitter schematic diagram built using transistor bc109c. This circuit is designed with limited power output to match the fcc regulations and still produces enough amplitude modulation of voice in the medium wave band to satisfy your personal needs.
