System Description

The ARC-164 is a military UHF AM aircraft station that operates between 225-399.975 MHz (the NATO harmonised UHF band 225-400 MHz is also a subset of this particular band as defined by the NJFA) and transmits at 10 watts.^[2] It features a separate guard receiver for monitoring 243 MHz while simultaneously monitoring the active channel selected, an ECCM slice capable of storing multiple Word-of-Day patterns for Havequick operation, and can also serve as a channel selector and audio demodulator for separate UHF DF systems. There are 2 common installations: remote and panel. With a remote installation, the R/T is in a remote location, while the panel installation features an all-in-one R/T and control panel.
