(2) Radio set AN/GRC-50(V).
Radio set AN/GRC-50 is a
transportable medium capacity FM radio set designed to provide
multichannel, two way communications in the UHF range. The AN/GRC-50
operates in conjunction with 4/12/24-channel FDM or 12/24-channel PCM
equipment. You secure the radio system using TSEC/KG-27 (PCM only).
The AN/GRC-50 operates in a variety of configurations as a radio
terminal or repeater station in the communications network. Current
plans are to replace the AN/GRC-50 with the AN/GRC-103. Figure 1-14
shows the AN/GRC-50 and some typical equipment configurations.
