Reform high performance FM transmitter with FM-adjustment head ----- FM Transmitter

Reform high performance FM transmitter with FM tuning head Recently, the author uses a highly fractional portion of the FM head (FM). Made a FM transmitter, very interesting, and it is very interesting to share with you. The modulated head used is a Miz meters tuning head, of course, other modulated heads with the vibration output. Because when making it, only the local oscillator is used, so even if high amplifier and mixed damage are not affected. And in actual use, the FM head is also very small. Therefore, you can use some damaged FM heads. With this Mitzmi FM tuning head, the fabricated FM transmitter is shown in Figure 1. Simply remove the components on the original frequency head, then add some components as shown in Figure 1. The antenna is tied with a 50cm rod antenna or a soft wire. VD1 and VR1 are highly used as highly precision components to ensure the stability of the frequency. Welding is good. Enter the audio signal of VCD at AUDIO. Then use a FM radio (preferably a numerical) to find a frequency without a local station within 100MHz ~ 108 MHz. Then turn the VR1, you can receive the signal, then adjust the VR2 to make the volume without distortion, you can use the portable radio to listen to the portable radio. Moreover, with your hand touched the antenna, the frequency does not change. It is possible to be a superior performance FM transmitter. If you want to make an FM wireless microphone. As long as the circuit is added to the circuit, it can be a high performance wireless microphone. You can also refer to the "Electronic News" previous article, and the external power renewal makes the emission distance more. U Heilongjiang Yu Xiangtao
