TKR-850E Analogue Base Station/Repeater (EU Use)

UHF Repeater - High Power

High stability 100% continous duty
The TKR-750 high stability 1.5PPM TCXO modules, 100% duty RF power amplifier (25W output), integrated die-cast heat sink and forced-air cooling provides site-friendly, continuous operation. The TKR-750 has a high power output of 50W (at 50% duty) while the TKR-850 offers 40W (at 50% duty).

16 full-duplex channels & single priority scan
With 16 full-duplex channels, these versatile repeaters can function as a base station or repeater backup unit to suit various applications. The built-in 16 channels are preset and selectable from a remote control utilizing the remote I/O connector or pre-programmed key on the front panel. The programmable function (PF) keys located on the front panel permit adjustment and
testing of repeater sites. In addition, single priority scan is available when the unit is operating in simplex mode.

QT/DQT with DSP multi-decode
For QT/DQT groups sharing the same RF signal range, DSP processing allows up to 16 QT/DQT signal variations to be processed simultaneously via the multi-decode function. Two decode tables (main/sub) are available to facilitate the setup of channels to different multi-decode ranges.

Companded audio
A built-in compander contributes to improved audio when operating as a simplex base station. A wide/narrow setting is available for each channel.

Flash memory
Flash memory permits updates, advanced feature sets and system architectural changes to be made electronically without ever opening the unit. This means faster modifications for system operators and less downtime for users.

2-Digit numeric LED display
The 2-digit numeric LED on the front panel displays channel number and operational status information, such as an “unlocked” error.

LED indicators
The LED indicator lights provide clear system status information at a glance, including transmit, receive, battery backup, and DC power. If the transmitter or receiver becomes unlocked, the LEDs flash for quick problem assessment.

Wide/narrow channel bandwidth per channel
The TKR-750 can handle both existing wideband systems and emerging narrow band applications for extra flexibility and long-term viability. For VHF channels, compatibility is provided for a minimum frequency of 2.5kHz (US only).
