Product DetailsThe RC-GM300 comprises 2 modules which when fitted to 2 x Motorola GM300 mobiles will turn them into a talkthrough repeater. Use 2 tranceivers for in band talkthrough or 2 different band sets for one way crossband. Fit 2 radios in a vehicle and use as a local on-site repeater.
This module just plugs in place of the Motorola speaker plugs and the repeater option requires programming into the radio using standard GM300 software. There are no modifications required to the radio, and there is a pot on one of the modules to set audio path level.
