Surecom SR-628 is a Duplex Repeater Controller box that allows two radios to work as a cross band repeater. A radio is simply connected to each side of the control box using the correct cable. When the receiving radio receives a transmission, the opposite radio instantly re-transmits the transmission; this works in either direction.

The Surecom Duplex Repeater Controller is supplied with an AC adapter but can be powered by any 5V DC USB 1A power source such as a cigar lighter 1A 5v adapter.

How It Works

When the radio units are connected, the received signal on a radio unit will be real time transmit on the other radio unit. This can be cross-band or cross-mode. For example VHF/VHF, UHF/UHF, UHF/UHF, DMR/Analogue modes or any combination using two portable radios.

Input A: Channel A transmits when channel B is receiving

Input B: Channel B transmits when channel A is receiving
