radio frequency receiver-transmitters that
are integrated into a 19in rack mount transit
case. Each receiver-transmitter exhibits
excellent radio-frequency co-site
performance, which enables deployment of
multiple 721S Blade systems at one site.
With a compact size for easy deployment,
the 721S Blade has been fielded with
numerous voice communications systems. It
features a user-friendly interface for simple
and intuitive operation. It’s compatible with
USAF Rome Touch Control Software, as well
as ED-137 VoIP audio compatibility using
the G.711 codec. Iversen points to the
following as benefits of the 721S family of
radios: compact, modular packaging that
minimizes transport space and simplifies
deployment; the lowest size, weight and
power usage footprint in the dual-band V/
UHF market; no radio-frequency
compromise for the transportable/
expeditionary market space; a 10-minute
setup time in deployable configurations; a
modular design that enables easy upgrades
and Clarity noise reduction that boosts
area of coverage 4X over conventional
V/UHF transceivers.
The Clarity noise reduction technology is
a standout feature of the 721S family. “Clarity
significantly reduces operator fatigue by
removing non-syllabic background audio in
both transmit and receive operations,”
Iversen says. “That could be noise from a
cockpit, an aircraft, a heating and cooling
system, street noise, office sounds or signal
interference from co-location pollution.” The
result is a clean and uncluttered
communication signal between ground radio
operator and pilot.
When disaster strikes
The third system in the 721S radio family is
the 721S Emergency Transceiver Radio. Like
the others in the family, it checks the boxes
for a portable ground-fixed ATC radio.
