【
CTCSS/CDCSS ENCODER & DECODER】
Set up talkgroups/users with unique CDCSS/CTCSS to prevent unwanted conversations on the same frequency.
【
FLOATING CHARGE】
The TR-50 provides selectable AC(100~240V 50/60Hz)/DC(10.2 - 14.6V) power supply. Users can equip battery back-up system connected to the external DC jack with floating charge function in the mean time. This supports auto-switching to DC battery once the AC power supply fails.
【
MULTI-CONTROL FOR ONSET OF THE FAN】
The powerful DC brushless fan inside the cabinet is to effectively ensure the transmitter's durability and stability while working at tough situations. Three options for the jumpers are PTT controlled, Continuous and Temperature controlled respectively.
【
LED INDICATORS】
The LED indicators on the front panel highlight system status at a glance, including power-up, receive and transmit.
【
PROGRAMMABLE CHANNEL SPACING】
Users can set either a 25KHz or a 12.5KHz channel spacing to accommodate present and future channel allocations according to local radio regulations.
【
PC PROGRAMMING & TUNING】
The repeater provides tuning in the field from a desktop or portable PC. Radio parameters for programming are TX/RX frequency, CTCSS/CDCSS, squelch level, etc.
【
BASE STATION CAPABILITIES & LOCAL SPEAKER】
The TR-50 can be operated as a full-duplex base station with the optional SM-08R Microphone connected. In addition, a built-in speaker on the front panel makes it available that the channel conversation can be monitored.
