Simpls 1 Piece MW Medium Wave Transmitter AM Radio Transmitter DIY Circuit Board AMT-MW207 525-1605KHz

Product description

• There is no need for an external antenna (tens of meters for medium wave), and the magnetic field leaked by the magnetic rod affects the receiver, which is easy to implement and the transmission distance is relatively short; There are many interfaces, designed with waveform test terminals, audio sockets, external power sockets, etc., which are easy to use and expand functions. It can be connected to an external power supply or installed with a battery for use.
• The circuit is simple. It is only composed of common triodes and resistance-capacitance inductive components, without audio , which is easy to make; The sound quality is good. Within the rated transmission distance, the sound quality is close to that of FM broadcasting, and the signal-to-noise ratio is good.
• This kit adopts full discrete circuit, which is especially suitable for students to learn the working principle, practice production and test; The variable capacitor uses a double-connected variable capacitor, and the two-connection parallel connection can obtain sufficient capacity; Using double-sided circuit, the board base is glass fiber material, the thickness is measured about 1.5-1.6mm, the pad is sprayed with tin, and it can be directly welded without grinding.
• AMT-MW207 medium wave transmitter is a simple AM signal source suitable for amateur electronics enthusiasts and radio enthusiasts. It uses a magnetic rod to transmit electromagnetic waves without an external antenna. It can be used to test ordinary medium wave radios in places where the radio signal is insufficient. As well as ore radios, it can also be used as an instrument for debugging medium wave radios.
• This product has been revised for n times so far (mainly to modify the wiring of the circuit board and the circuit remains unchanged), and it is still in the process of continuous improvement. Usually minor and insubstantial modifications, such as slight movement of component positions and minor adjustments to wiring, will not change the version number, nor will they not be re-photographed and uploaded, hereby declare.
