Apparatus in a transceiver for broadcasting priority rated messages on a channel shared by a multiplicity of similar transceivers, converts an analog audio frequency message to compressed digitalized format which is stored, encrypted, and encoded with a priority rating and recipient identity code. A central data processor prevents broadcast of the message while any other message of higher priority rating is being broadcast, or interrupts broadcast of the message when broadcast of another message of higher priority is detected, or interrupts broadcast of any other message of lower priority than that of a message waiting to be broadcast. Received messages bearing the recipient's identity code are stored and played back in order of their priority rating.
