2P3 Radio Medium Wave Transmitter Signal Source Experimental AM Transmitter for Crystal Radio Receiver Finished

2P3 Radio Medium Wave Transmitter Signal Source Experimental AM Transmitter for Crystal Radio Receiver Finished leírása

1. Simple Circuit: This transmitter uses common transistors and resistors, capacitors, and inductors, and is modulated by an audio transformer. It's a pure AM medium wave transmitter, easy to manufacture and operates smoothly with correct soldering.
2. Excellent Sound Quality: Tests have shown that the sound quality is close to FM radio within the rated transmission distance, with a good signal-to-noise ratio.
3. No external antenna required: The radio transmits the signal entirely through the magnetic field leaked from the ferrite.
4. Multiple Interfaces: External power supply, battery, audio input, and test terminals for easy use and functional expansion.
5. Can be powered by either battery or external power.

Simple Debugging: The resistor parameters are pre-matched to the corresponding transistor parameters. Simply solder all components correctly for optimal operation, requiring only adjustment of the band coverage.
