Description

radio2P3 medium wave transmitter signal source for radio experiment DIY Description This Transmitting distance: Ultra-aberrant medium wave radio about 1 meter Direct-discharge medium wave radio is about 0.5 meters. transmitter is suitable for amateur electronics enthusiasts, radio enthusiasts simple easy AM signal source, in the area of the radio signal is insufficient to use it to test the production of medium wave radio, ore radio debugging effect. I. Features 1. Simple circuit: it is composed of common transistors and capacitive sense elements, and uses audio transformer modulation, which is pure AM. Pressure regulator modulation, for pure AM medium wave transmitter, production difficulties, welding errors can be Normal operation; 2. Good sound quality: the sound quality is close to FM broadcasting in the rated transmitting distance by experiment, and the signal-to-noise ratio is good. Good signal-to-noise ratio; 3. No external antenna: rely entirely on the magnetic field of the magnetic bar leakage radio transmission to the radio 4. Many interfaces: external power supply, battery, audio input, test terminals, easy to use and extend the function; 5. Can be powered by battery or external power supply. 6. Simple debugging: resistor parameters and matching transistor parameters have been matched, as long as all the As long as all the components are correctly welded, it can work well and only need to adjust the band coverage. package ： 1pcx radio2P3 medium wave transmitter signal source for radio experiment DIY If you have any questions, please contact us in time, we will help you deal with the problem for the first time.
