ABSTRACT:
A subscriber broadcast system broadcasts encrypted fax (facsimile) messages on an FM subcarrier. The subcarrier is received by an FM data receiver which includes an FM receiver tuned to a selected FM subcarrier, a subcarrier detector and a demodulator. A fax message, having the subscriber's address, is received, decrypted, and stored in memory. When the subscriber's fax machine is not busy, i.e., not receiving a fax over a telephone line, the FM data receiver transmits handshake signals and then transmits the stored fax message to the subscriber's fax machine.
