A channel priority encoder in a mobile/repeater unit of a two-way communications system allows a low power detached, unit to remotely select a desired channel for high power repeater transmission to and reception from a base station. The selection can be latched-in permanently or can be made to revert to a home channel after a delay. The mobile unit can override a channel selection made by the detached unit but another mobile unit would provide the repeater function.
