HIGH STABILITY 100
% CONTINUOUS DUTY
The 50-Series high stability 1.5PPM TCXO
modules, 100% duty RF power amplifier (25W output), integrated
diet-cast heat sink and forced-air cooling provides 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)
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.
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
"unlocked" 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 is set for 12.5Khz narrow band.
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 Signaling 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
set-tings: RX helical resonator block bandwidth, MCF waveform, Quad
detector coil, and MIC sensitivity.
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.
EMBEDDED MESSAGE WITH PASSWORD LOCK
The repeaters 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.
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
