Abstract:

A simulcast communication system for permitting the same audio signal to be simultaneously broadcasted from a plurality of base stations located remotely from a dispatch station used to transmit this audio signal to each of the base stations over conventional telephone lines is described. The simulcast communication system generally comprises first circuit means for equalizing the audio signal transmission characteristics from the dispatch station to each of the base stations in response to at least one test signal broadcasted from each of the base stations, and second circuit means for generating a synchronized squelch signal at each of the base stations in response to a pilot signal transmitted to each of the base stations with the audio signal and a phasing signal transmitted to each of the base stations at the beginning of the audio signal.
