Am Transmitter Circuit. The circuit is in two halfs an audio amplifier and an rf oscillator. At the heart of the circuit is a crystal oscillator.
This simple am transmitter circuit include of many parts. At the heart of the circuit is a crystal oscillator. This circuit can pick up medium wave stations in your area.
This is made by winding 30 turns of number 24 wire on an amidon ft 50 61 ferrite core.
This simple am transmitter circuit include of many parts. The picture to the left is a high quality radio transmitter for the a m. The amplified audio signal modulates the rf carrier generated by the crystal oscillator built around transistor t4. The oscillator is built around q1 and associated components.
