Kenwood TKR 750/850 VHF/UHF FM Repeater-Base Units

DISCONTINUED

Features

High Stability 100% Continuous Duty
The TKR-850's high stability 1.5PPM (2PPM for TKR-750) TCXO modules, 100% duty RF power amplifier (25W output), integrated die-cast heat sink and forced-air cooling provide 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 and Single Priority Scan
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 �gunlocked�h 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-750/850 can handle both existing wideband systems and emerging narrow band applications for extra flexibility and long-term viability.

Windows Programming and Tuning Software
The repeater can be programmed from a Windows® compatible PC quickly and efficiently �\ without ever opening the case �\ using the optional FPU and programming interface cable. Among the radio parameters available for programming are:

• Squelch
• DQT balance
• RX audio signal output (RA)
• QT deviation
• RX detector signal output (RD)
• DQT deviation
• RX frequency
• Test tone deviation
• RF output power
• CW ID deviation
• Maximum deviation
• Repeat gain
• TX audio input (TA)
• TX frequency
• Signaling deviation (TD)

6 PF Keys and Local Speaker
In addition to 6 programmable function keys (each equipped with an LED indicator), the front panel has a built-in speaker. This makes it easy to check on repeater site reception conditions. There is also a microphone terminal to allow audio transmission.

Emedded Message with Password Lock
The repeater�s flash memory can store an electronic message �\ with password protection �\ containing owner identification, property ID numbers, user and department names, service records, etc. Additionally, the FPU can be used to display an electronic serial number. A unit can thus be electronically identified even if the external labels, marking or factory serial numbers have been removed.

External Control I/O
The D-SUB25 connector on the rear panel provides a control I/O interface for external controllers to enable customization and integration with other features and capabilities.

Durable Die-Cast Chassis Constuction
The die-cast aluminum chassis with integrated heat sink is the key to the TKR-750/850�fs durability, service level and reduced weight. The entire unit is sealed to provide long-term protection even in the most demanding operating conditions.
