Shared channel communication system
First Claim
1. A communication system for providing two-way communications in a predetermined propagation area, said system comprising:
- a first antenna;
a scanning receiver coupled to said first antenna;
a second antenna;
at least one repeater coupled to said second antenna, said repeater operable on any one of a plurality of channels;
a computer coupled to said repeater for controlling the channel of operation of said repeater and coupled to said scanning receiver for obtaining traffic information from said receiver and storing the information, said computer including memory containing a table of channels and station IDs, wherein a station ID is associated with a particular channel; and
wherein said computer causes said repeater to operate on an available channel, as indicated by said traffic information, using the station ID associated with the channel.

Abstract
A communication system includes a scanning receiver coupled to a first antenna, a plurality of repeaters coupled to a second antenna, wherein each repeater operable on any channel in a band, and a computer coupled to each repeater for controlling the operation of each repeater and coupled to the scanning receiver for obtaining traffic information from the receiver and storing the information in memory. The memory also contains a table of channels and station IDs, wherein a station ID is associated with a particular channel. Each repeater operates on an available channel, as indicated by the traffic information, using the station ID associated with the channel. The repeaters themselves can be used for obtaining traffic information, eliminating the scanning receiver. The repeaters do not have final amplifiers. Instead, a low level combining circuit couples the signals from each repeater to a single linear amplifier.
