The low noise GaAs-FET ATV3 Amateur Television Converter converts any TV receiver to a fast scan ATV monitor without incurring the expense of commercially made equipment. The ATV3 converter covers the 420 to 450 MHZ ATV range using channel 2, 3, or 4 on a standard TV set, without modification to the set. The ATV3 circuit consists of a low noise, high gain GaAs-FET RF front end, a 2nd RF stage, a double balanced mixer, a temperature compensated VCO controlled by a varicap diode (for remote tuning, if desired), and a pre-IF amplifier stage. The RF energy being received is converted down from the 420 to 450 MHz range to TV channel 2, 3 or 4. Power supply requirements are not critical. A +12 VDC regulated supply that can supply up to 75 mA is required. The converter may be mounted at the receive antenna and tuned by a remote potentiometer so as to reduce losses in the coax feedline at the higher frequency.
