VHF/UHF Desktop Repeater
The TKR-720/820 desktop repeater
provides a quality solution for any small to medium-sized RF communications
system, whether it's busy downtown in 'intermod alley' or working a lumber
yard in the suburbs, The Rugged, compact design utilizing advanced synthesized
RF technology lets you build a quality system that users can depend on
around the clock
MAIN FEATURES
-
Synthesized design for rapid set-up
and reliable performance
-
Adjustable power output suitable
top small to medium sized applications
-
High performance receiver works
equally well in urban, suburban and rural areas
-
Field programmable Quiet Talk (QT)
and Digital Quiet Talk (DQT) signaling systems
-
Compact packaging top desktop operation
-
Die-cast chassis and large heatsink
provide a stable foundation top heavy duty-cycle use
-
Modular design isolates receiver
and transmitter sections top maximum reliability and shielding
OTHER FEATURES
Advanced synthesized RF design
means
the TKR-720/820 is easy to program and reconfigure as necessary, utilizing
E2PROM technology, so you have both flexibility and reliability
combined in a compact, attractive package. In addition, the temperature
compensated crystal oscillator (TCXO) provides the utmost in frequency
accuracy and stability.
The adjustable RF power output
delivers just the right amount of coverage for your requirements.
It can be configured with low power for small industrial plants on UHF
(TKR-820) or high power on VHF (TKR-720) to cover an entire valley in the
remote wilderness. Your technician can program the UHF power from
2 to 20 watts, and the VHF power from 15 to 50 wafts.
The high-performance receiver
has excellent sensitivity, selectivity, intermodulation and spurious/image
rejection specifications so you can operate the unit equally well in both
RF-congested urban areas and wide open rural settings.
The Quiet Talk (QT) and Digital
Quiet Talk (DQT) signaling systems allow you to operate up to 8 tones,
including cross tone or cross code. And because users only hear traffic
relevant to their job, productivity and overall system effectiveness goes
up.
The compact desktop design
means that you do not have to create special rooms with environmental controls
- the TKR-720/820 is equally at home on a working desktop at the center
of the action or in a dedicated communications equipment room.
The die-cast chassis and large
heatsink keep the circuitry well-protected from physical abuse and
enable long operating hours. And if the AC power goes down, the optional
DC autorevert feature keeps your communications system up until technical
help arrives.
Inside, the modular design
carries the dependability factor even further, separating the receiver
and transmitter circuits for optimal shielding and isolation.
