This circuit is a simple audio/video transmitter with a range of 3 to 5 meters. It takes an A/V signal from a source like a VCR and transmits it using amplitude modulation of a 175.25 MHz video carrier and 180.75 MHz audio carrier at VHF channel 5 frequency. The transmitter consists of a transistor oscillator at channel 5 frequency mixed with a 5.5 MHz FM oscillator for audio. Tuning the circuit involves adjusting the channel 5 frequency trimmer capacitor for transmission.
