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.
Simple am transmitter and receiver circuit diagram. This circuit is available in kit form and can work well since the kit available. Simple ir audio link circuit applications. Apply the audio signal at transmitter section using a mobile phone or a music player. 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.
Make sure that distance between transmitter and receiver sections is below 30cm. The design is simple and sensitivity and selectivity of the receiver are good. Radio receiver working principle. The circuit is quite simple and easy to build since it applies only a few electronic mini mw transmitter.
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. It is similar in principle to the zn414 radio ic which is now no longer available. You will love this. Here is the circuit diagram of a simple am transmitter circuit that can transmit your audio to your backyard.
The following is a circuit of a simple am transmitter. Station 1 is broadcasting at am 920 station 2 at am 1460 and station 3 at am 1040. The schematic shown below is a simple am receiver circuit uses only one transistor and some other components. Disconnect the batteries from transmitter and receiver.
Now you can listen the sound from speaker.
