The Model HDM-1, frequency agile demodulator, has been designed to receive and demodulate all UHF, VHF, and CATV channels to baseband audio, video and multiplex signals. The HDM-1 uses a microprocessor driven PLL synthesized tuning circuit to assure precise tuning and accuracy. The microprocessor controls all functions and provides for easy channel selection using front panel channel up/down buttons and a large LED display.
