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

 

 

High-performance features — such as 16 full-duplex channels, flash memory, and PC/manual tuning — provide crystal-clear and reliable communications to make TKR-750/850 VHF/UHF FM repeaters the first choice for demanding applications.

 

 

 

1. 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 reliable 24/7-operation. The TKR-750 high power output is 50W (at 50% duty) a TKR-850 is 40W (at

 

50% duty).

 

 

2. 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.

 

 

3. 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.

 

 

4. 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.

 

 

5. 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.

 

 

6. 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.

 

 

7. 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.

 

 

 

8. 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. For VHF channels, compatibility is provided for a minimum frequency of 2.5kHz (U.S.A. only).

 

 

9. 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.

 

 

 

10. 6 PF KEYS & 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.

 

 

11. 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.

 

 

12. 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.

 

 

13. BATTERY BACKUP SYSTEM

 

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