Abstract
In a mobile repeater system there can be two priority repeaters at two adjacent locations which are out of range of each other, but not out of range of each other's portable units. Reception of a tone coded signal from a portable raises the squelch threshold in both repeaters, thus decreasing the portable-to-repeater range without decreasing the repeater-to-repeater range. Interferences caused by simultaneous transmission is eliminated since only the appropriate repeater is activated.
