UHF: RX: 453.31250Mhz TX: 463.31250Mhz
VHF: RX: 152.61250Mhz TX:162.61250Mhz

But please remember, receive should adjust with transmit in same direction. To make sure TX and RX still have previous offset.

  1. I have a RT 97 repeater which is connecting the radios properly but I get a lot of static and cant hear what anyone is saying. What must I do to improve the quality?

  2. I am having problems programming my new RT97. It works out of the box, but I want to change the CT code from default to our normal one. When I connect the programming cable the LCD display backlight comes on purple, but frequencies etc. are not displayed. Is this normal? When I try to read I get an error message saying “Abnormal reading and writing check the connections are correct or walkie-talkie power supply is turned on”

    As I said, LCD backlight on, no data displayed, not able to read or write to device.

    Thanks, Garry

    1. We tested the RT97 with the 10w handheld radio with the range of about 9km, and one of our customers said it can reach 35km.
      The range is based the antenna and the operating environment

      1. Right dear. your answer is real. even I use RT97 UHF in urban centers (JAKARTA INDONESIA) can reach a distance of 67km (still normal).
        but that antenna that I use is my own assembly. even I just installed the antenna only 15 meters from the ground. even though there are very many buildings around the antenna that are VERY HIGH blocking the antenna. but that in no way affected him. awesome right? thanks.

        1. hi, sometimes the range of the repeater is not only based on its power, but also based on the antenna, use the high gain antenna and high antenna. so if you want to use the repeater in best state, you need to make sure them.
