INTERCEPTION

In addition to the built-in COMSEC capability of the SINCGARS radio,

it confronts an enemy attempting to monitor friendly traffic with the

rapid change of frequencies over a wide range. To intercept friendly

traffic, an enemy must be able to match the FH data and sync time of

the friendly net.

JAMMING

Jamming a SINCGARS FH net can be done, but only with extraordinary

effort and commitment of equipment on the part of the enemy. Tests

have shown that even when 30% of the FH channels have been

jammed, a significant achievement, voice messages are still quite

understandable.

LOCATING

Although it is relatively easy for an enemy with direction finding

capabilities to accurately locate stations broadcasting in SC mode,

experience has shown that it is nearly impossible to determine the

location of an FH station.

FREQUENCY SHARING

SINCGARS hopsets, because of the rapidity of frequency hopping, can

include frequencies used by single channel nets and mobile

subscriber equipment (MSE). The frequency manager at division,

corps, or higher headquarters ensures best overall usage of

frequencies when developing hopsets.

SINCGARS radios will communicate with VRC- 12 Series radios, and

COMPATIBILITY

similar radios of our Allies, in the SC mode. Also, the retransmission

(RXMT) feature can be used as the interface between FH and SC nets

when appropriate.

Loadsets containing TEKs and TSKs are good to use for 30 days.

UPDATE PERIODS

ANCDs provide an additional 30 days of reserve data. In short, there is

no requirement to update data for 30 days and then the unit has

another 30 days to get their ANCDs reloaded with new data.
