Receiver, Radio GRR-24(V) is a single channel solid-state superheterodyne receiver that operates in the amplitude modulation (AM) mode in the radio frequency (rf) range of 225.00 to 399.95 MHz. It is capable of reception in this frequency range on any one of 3500 channels spaced 50 kHz apart using the 50 kHz IF crystal filter or on any one of 7000 channels spaced 25 kHz apart using the 25 kHz IF crystal filter. The operating frequency is determined by either the oscillator crystal frequency selected or the dial setting of the oscillator synthesizer. An oscillator-synthesizer module is available which is directly interchangeable with and replaces the crystal oscillator module. | |||

GRR-24 Radio Receiver Set - A UHF Single Channel Radio Receiver set built by ITT Aerospace for air-ground communications. Put in place at USAF and RCAF heavy radar sites in the mid-1970s to replace similar radios that used vacuum tube technology. One component of the USAF Rivet Switch program.
