12 COVERT OPERATION
The small size of the MWRSM unit may allow for its selective use in covert applications.
The remote monitor PTT function means someone else can enable “listening” without
the covert operative having to touch anything. As audio is duplex (bidirectional) you
can also talk to them at the same time allowing vital messages to be passed on even
when an operative is transmitting. The advanced model : MWRSM2 unit provides 128
bit encryption version to ensure high levels of voice security, while the standard
MWRSM versions provide 64 bit encryption. Both encryption types are based on the
well recognized highly Mobile ‘SAFER” format.
