Abstract: A multi-radio equipment arrangement comprises multiple transceivers of different band splits. A preferred arrangement utilizes at least one transceiver for communicating on digital "trunked" RF communications system and at least one transceiver for communicating on a wide-area "conventional" RF communications system. The multi-radio equipment transceivers communicate with each other and with an equipment control unit via a common internal serial data bus to form a multi-radio local network. Each transceiver incorporates a microprocessor controller that includes appropriate task management and serial bus interface software routines for operating and communicating with other devices on the bus. The control unit provides a user interface comprising conventional radio equipment front-panel controls. A "trunked" system transceiver is automatically selected whenever its measured audio quality exceeds a predetermined user-programmable minimum level.
