UHF Single Band Radio Repeater has an illuminated LCD so it can be used at night. Its busy channel is locked and has CTCSS and DCS capabilities. It can communicate, program, and set parameters and channels through a computer. Cross with repeater function. It is a commercial land mobile multi-band radio. UHF Single Band Radio Repeater features dual receive operation with independent volume control, narrowband operation for land mobile frequencies, broadband operation for amateur frequencies, and optional base station configuration. It has multiple scan modes, including priority scans. UHF Single Band Radio Repeater allows for longer distance communication in open areas with virtually no obstacles. The keypad lock prevents accidental activation of the function/mode button. The button tone provides the sound of each button for response or confirmation. It can turn off all tones using the mute action.
