The cue and manual frequencies are included in the eight single-channel frequencies. SINCGARS stores eight single-channel frequencies and six separate hopsets. Currently, in the FH mode, SINCGARS is only compatible with other Air Force, Marine, or Navy SINCGARS radios. It is compatible with all current US and allied VHF radios in the single-channel mode on 50 kHz channels. SINCGARS operates in either the single-channel or FH mode. In this chapter, the term SINCGARS pertains to ground and airborne versions. Airborne and ground versions are interoperable in FH and single-channel operations. (2) The airborne versions differ in installation packages and requirements for data capable terminals. The operator whispers into the handset and is heard at the receiver in a normal voice. The ground versions are equipped with a whisper mode for noise restriction during patrolling or while in defensive positions.
The secure devices are compatible if the same cryptonet variable is used in the ICOM radio and the VINSON device. The RT-1523 has internal COMSEC circuits (origin of the ICOM designation), and the RT-1439 uses the VINSON secure device. The main difference between radios is the device used to provide secure communication. (1) Either the RT-1523 ( Figure 3-1) or the RT-1439 ( Figure 3-2) is common to all ground-based sets. All avionic models require external COMSEC devices. There are two ground unit versions (RT-1523 integrated COMSEC (ICOM) and RT-1439 non-ICOM) and three avionic versions (RT-1476/1477/1478). The primary component of SINCGARS is the receiver/transmitter (RT). Additionally, modular design lessens the burden on the logistics system to provide repair parts.ī.

SINCGARS radio set configurations provide identical, or in most cases, improved capabilities when compared to the AN/VRC-12 series radio sets they replace. The individual components are totally interchangeable from one radio set to the next. SINCGARS radio systems are modular component sets.
