1、TKR-750/850 VHF/UHF FM Repeater-Base Units HIGH STABILITY 100% CONTINUOUS DUTY The 50-Series high stability 1.5PPM TCXO mod- ules, 100% duty RF power amplifier (25W output), integrated die-cast heat sink and forced-air cool- ing provides site-friendly, continuous operation. The TKR-750 has a high po

2、wer 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

3、and selec- table 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 prior- ity scan is available when the unit is operat

4、ing 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 t

5、o 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 m

6、ade 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 dis- plays channel number and operational status information, such as an “unlocked” error. LED IN

7、DICATORS The LED indicator lights provide clear system sta- tus 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

8、can handle both existing wide- band systems and emerging narrow band appli- cations for extra flexibility and long-term viability. For VHF channels, compatibility is provided for a minimum frequency of 2.5kHz (US only). WINDOWSPROGRAMMING AND TUNING SOFTWARE The repeater can be programmed from a Win

9、dowscompatible 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 Signaling balance RX audio signal output (RA) QT deviation RX detector signal output (RD) DQT deviation RX

11、 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. EMBEDDED MESSAGE WIT

12、H PASSWORD LOCK The repeaters flash memory can store an elec- tronic message with password protection containing owner identification, property ID num- bers, user and department names, service records, etc. Additionally, the FPU can be used to display an electronic serial number. A unit can thus be

13、electronically identified even if the exter- nal labels, marking or factory serial numbers have been removed. EXTERNAL CONTROL I/O The D-SUB25 connector on the rear panel pro- vides a control I/O interface for external con- trollers to enable customization and integration with other features and cap

14、abilities. BATTERY BACKUP SYSTEM Several power-saving features, including a dis- play-off function, help to reduce energy con- sumption. A built-in backup system supports automatic switching to a 12v battery* if the AC- based power supply* fails. DURABLE DIE-CAST CHASSIS CONSTRUCTION The die-cast al

15、uminum chassis with integrated heat sink is the key to the TKR-750/850s durabil- ity, service level and reduced weight. The entire unit is sealed to provide long-term pro- tection even in the most demanding operating conditions. High-performance features such as 16 full-duplex channels, flash memory

16、, and PC/manual tuning provide crystal-clear and reliable communications to make Kenwoods TKR-750/850 VHF/UHF FM repeaters the first choice for demanding applications. *Not supplied Options KMC-30 Microphone Specifications TKR-750 TKR-850 GENERAL FreQuency Range Type 1: 146-174 MHz 440 - 470 MHz Num
