Kenwood TKR 850

Product Details

Kenwood TKR-850 Repeater

High-performance features — such as 16 full-duplex channels, flash memory, and PC/manual tuning — provide crystal-clear and reliable communications to make Kenwood’s TKR-850 UHF  repeaters the first choice for demanding applications.

• HIGH STABILITY 100% CONTINUOUS DUTY

  The 50-Series 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.

  
  

• 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.

  
  

• 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.

  
  

• 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.

  
  

• EMBEDDED 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.

  
  

• BATTERY BACKUP SYSTEM

  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.

  
  

• PROGRAMMING AND TUNING SOFTWARE

  The repeater can be programmed from a Windows system 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

  - RX audio signal output

  - Busy channel forbidden

  - RX detector signal output

  - RX frequency

  - RF output power

  - Maximum deviation

  - TX audio input

  - Signaling deviation

  - Signaling balance

  - QT deviation

  - Test tone deviation

  - CW ID deviation
