AMT-MW207 Medium Wave Radio Transmitter AM Radio Transmitter 525-1605kHz Item description Warm Tips Please note that the appearance of DIY KIT and Finished version are different, but the functions and circuits are the same. For safer and faster delivery, the transmitter does not include a battery(AA*4). The slight bending of the antenna magnetic rod has no impact on the use performance; the Antenna magnetic rod is easy to break when hit by external force, please handle it with care. When the radio is too far away from the transmitter (more than 1 meter), the effect will deteriorate. Increasing the supply voltage can increase the waveform amplitude, but will not change the actual available transmission distance. Features Multiple interfaces: designed with waveform testing terminal, audio socket, external power socket, etc., easy to use and expand multiple functions.
