Kenwood TKR-750 Repeater

Product Description

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.

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.

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 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.

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

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.

The TKR-750/850 can handle both existing wideband systems and emerging narrow band applications for extra flexibility and long-term viability.

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)

Manual tuning is available for the following settings: RX helical resonator block bandwidth, MCF waveform, Quad detector coil, and MIC sensitivity.

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.

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.

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.

Several power-saving features, including a display- off function, help to reduce energy consumption. A built-in backup system supports automatic switching to a 12v battery* if the ACbased power supply* fails.

The die-cast aluminum chassis with integrated heat sink is the key to the TKR-750/850's durability, service level and reduced weight. The entire unit is sealed to provide long-term protection even in the most demanding operating condition
