Brand New Motorola GR-3188/3688 Two-way Radio Walkie Talkie  Base Station/ Repeater UHF 403-470MHz 25Watts 8 Channels with DuplexerÂ
Importance: The frequency difference between TX frequency and  RX frequency in each Channel for UHF Repeater should be 10MHz, For Example:
CH1: TX 455.6375MHz RX:465.6375MHz (465.6375-455.6375=10MHz)
So you have to tell your desired Frequency to our salesman by leaving message or online after paying for your order. Thanks! Â
