The PRC-770 is identical in all respects to the AN/PRC-77, except that it has 1840 channels spaced at 25 kHz intervals instead of 920 at 50 kHz spacing. The AN/PRC-77 is a lightweight, two-watt solid-state communications system, providing FM voice communication in the VHF range from 30.00 to 75.95 MHz. Widely deployed in its manpack and vehicular configurations, the AN/PRC-77 continues to be the mainstay of the and free-world military forces. By virtue of this upgrade to 25 kHz spacing, the usefulness and effective life of this radio has been extended.
