GRT-22 UHF Radio Transmitter Set - A single channel UHF Radio Transmitter set built by mmmmm.
From TO 31R2-2GRT-102: Transmitting Set, Radio AN/GRT-22(V) is comprised of Transmitter Radio T-1109(V)/GRT-22, referred to as the UHF exciter, and Amplifier, Radio Frequency AM-6155/GRT-22, referred to as the UHF power amplifier. When only 10 watts is required only the exciter is necessary. An oscillator-synthesizer module is available which is directly interchangeable with and replaces the crystal oscillator module The UHF exciter, utilizing the oscillator-synthesizer is capable of transmission on any one of 7000 channels spaced 25 kHz between 225.00 and 399.975 MHz. The UHF exciter is a crystal-controlled self-contained solid-state assembly that operates in the amplitude modulation (AM) mode. It is capable of transmission on any one of 3500 channels spaced 50 kHz between 225.00 MHz and 399.95 MHz as determined by the operating frequency of the crystal used. The power amplifier is a self-contained unit that amplifies the 10-watt exciter output to 50 watts. The power amplifier utilizes a 350-watt plate dissipation beam power tetrode vacuum tube in a tuned cavity configuration. The amplifier operates Class AB linear. The 50-watt output is maintained by means of a closed-loop automatic power control action which is coupled back into the exciter. GRT-22 Radio Transmitter
