Unassembled Kit 2P3 Radio Medium Wave Transmitter Signal Source AM DIY for Crystal Radio Testing

Description:
- This transmitter is a simple amplitude modulation signal source suitable for amateur electronics enthusiasts and radio enthusiasts. It can be used to test the debugging effect of medium wave radios and mineral radios produced in areas with insufficient radio signals.

Features:
- Simple circuit: It is composed of common transistors and resistive capacitive sensing elements, modulated by an audio transformer, and is a pure amplitude modulated medium wave transmitter. It is easy to manufacture and can work normally without welding errors.
- Good sound quality: Through experiments, the sound quality is close to FM radio within the rated transmission distance, with a good signal-to-noise ratio.
- No need for an external antenna: entirely transmitted wirelessly to the radio by the magnetic field leaked from the magnetic rod.
- Multiple interfaces: external power supply, battery, audio input, test terminals, easy to use and expand functions.
- It can be powered by batteries or an external power source. (Note: battery is not included.)
- Easy debugging: The resistance parameters have been matched with the matching transistor parameters. As long as all components are correctly soldered, they can work well, and only the band coverage needs to be adjusted.

Effective Transmitting Distance:
- Ultra heterodyne medium wave radio: about 1 meter
- Direct broadcast medium wave radio: about 0.5 meters

Package Included:
- 1 x Transmitter Kit

Note:
- Please assemble it by yourself.
