AN/GRC-19 1 The Radio Set AN/GRC-19 includes the T-195 transmitter; the R-392 receiver and the MT-851 mount designed by Collins in the early 50\'s.
Their primary input voltage is 24-28VDC at  45 Amps. They were designed for vehicular use. The transmitter covers from 1.5Mc to 24.4mc,on either CW or AM and also was setup to use an external frequency shift keyer for RTTY operation. It uses high-level plate modulation on AM and semi-break-in for CW. The power output is in 100 to 125 watt area depending on the input voltage. The transmitter will tune automaticly to the antenna, The receiver is a superheterodyne using triple conversion on the eight lower bands and double conversion on all the other bands. The frequency range is .5 to 32 mc in 1-mc bands using a mechanical digital readout. It receives AM and CW, and SSB using the BFO for product detection of the signal. It has 3 positions of selectivity 2, 4, and 8kc. It also is unique in the fact that it uses 24VDC on both the plate and filaments. It likes higher voltage (28 to 30VDC) on the plates for better gain. It only has 200 milliwatts of audio output. Collectors Item.
