Simple Am Transmitter And Receiver Circuit Diagram
Here the short wave am transmitter circuit design diagram.
Simple am transmitter and receiver circuit diagram. All general purpose transistors should work in this circuit i used three bc109c transistors in my prototype the tuned circuit is designed for medium wave. Disconnect the batteries from transmitter and receiver. The schematic shown below is a simple am receiver circuit uses only one transistor and some other components. The 80 turns coil and 365pf variable capacitor form a tank circuit which receives the signal through the antenna and then the signal is detected by oa91 diode and amplified.
This circuit is available in kit form and can work well since the kit available. It is similar in principle to the zn414 radio ic which is now no longer available. The circuit is quite simple and easy to build since it applies only a few electronic mini mw transmitter. Used in audio communications to.
Radio receiver working principle. The following is a circuit of a simple am transmitter. 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. In figure 1 there are three radio stations each broadcasting at a different wavelength each station is broadcasting a radio signal consisting of a carrier wave and an audio signal.
You will love this. Station 1 is broadcasting at am 920 station 2 at am 1460 and station 3 at am 1040. Apply the audio signal at transmitter section using a mobile phone or a music player. Here is the circuit diagram of a simple am transmitter circuit that can transmit your audio to your backyard.
