Abstract: A frequency hopping radio frequency communication system and method in which keying (at Time T.sub.1) of a transmitter (Tx) automatically initiates the transmission of a predetermined number of cycles (C.sub.1 -C.sub.8) of a sync acquisition signal (W, X, Y and Z) at each of a number of different frequencies (A-G). The receiver (Rx) is being tuned through the same frequencies (A-G) at a relatively slower rate so that the sync acquisition signal is received at each of the receiver frequencies. Upon recognition of the sync acquisition signal and the cycle in which it is received, the receiver anticipates the end of the last cycle of the sync acquisition signal in synchronism with the transmitter and initiates tuning of the transmitter and receiver in accordance with a predetermined pseudorandom code. Additionally, a synchronization maintenance signal is sent approximately every ten seconds to insure that the synchronization between both radios is precisely maintained.
