AN/ARC-201 SINCGARS
The Army Single-channel Ground and Airborne Radio System (SINCGARS)
operates in the 30.000 to 87.975 MHz
frequency range. Early ground versions of
SINCGARS consist of a receiver-transmitter
(RT-1439) supported by external COMSEC
equipment assembled with other common
modules into manpack and vehicular
configurations. These radios are known as
non-integrated COMSEC (non-ICOM) since
they require the TSEC/KY-57 security
equipment for cipher text (CT) operation.
Newer production ground SINCGARS
receiver-transmitters (RT-1523 series) are
known asintegrated COMSEC (ICOM). They
have an internal module that performs the
cipher functions; thus, they do not need the
external KY-57 equipment. However on the
other hand,
The Army airborne SINCGARS
radio (AN/ARC-201/A) requires use of the
TSEC/KY-58 security equipment for CT
operation. All three versions of the airborne
radio handle voice; only the data bus version
(RT-1478) handles data through use of a data
rate adapter (DRA). Both ICOM and non-ICOM
versions of the radio are operationally
compatible in FH and CT operations.
