The remote control multi-file controller is as shown in the figure. This circuit has the radio transmitter and the wireless receiving and controller parts. The generator is the self-excited multivibrator circuit. The oscillation frequency f=l.44/(R1C2+R2C3). The controller uses the 30～40MHz amateur frequency range. The frequency selection circuit of the receiver outputs the high-frequency signal, and this signal is rectified by D1 and D2, and it also amplified by BG3 to be sent to the pin-1 of IC1. The IC1 uses the BH-SK-V type integrated package, it has the level 2 high power gain amplifier, the frequency selector, the plastic device and the trigger, driver.
