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.
