"IN BAND" PORTABLE AREA COMMUNICATIONS MOBILE REPEATER
Two-Way Radio is more flexible and useful if the radio communications can be extended beyond a vehicle. The Portable Area Communications Mobile Repeater (PAC-RT) provides a means for the operator of the vehicle radio to use the high power of the vehicle radio and yet have the flexibility to use a portable. The mobile radio is configured as part of a repeater system to accomplish this task. The coverage is then not limited by the portable but is virtually the same as the mobile radio to base station coverage. This gives the user the flexibility to depart from the vehicle, to communicate the short distance to the vehicle via the portable set, turn on the mobile radio transmitter and rebroadcasting the information to the base station. A portable radio equipped with a coded signal is used to activate repeater operation. Portable to portable communications without repeater operation is obtained without the signal. With the signal and using the repeater and also switching a portable to a mobile frequency the portable to portable range can more than double.
