An automatic link establishment (ALE) method of establishing a link between two or more HF radios or stations, and an apparatus using the same, are disclosed. The invention provides a transmission protocol that allows HF radios to rapidly exchange call data to enable the first radio and second radio to have knowledge of the frequency propagating characteristics used for communication. The method includes transmitting 24 bit words from the first station to the second station and vice-a-versa in the CALL. The words include a three bit preamble, at least about 3 bits of data to be transmitted from the second station to the first station, and a compressed representation of three characters of the address of at least one of the stations. The number of words transmitted during the CALL, RESPONSE and ACKNOWLEDGE are greatly reduced from the protocol defined in MIL-STD-188-141A Notice 2.

[ What is claimed is:] [1.] An automatic link establishment (ALE) method of establishing a link in a high frequency (HF) communication system between first and second stations, the first and second stations having first and second addresses assigned respectively thereto, the method comprising:transmitting a first 24 bit word from the first station to the second station, wherein the first word includes:a three bit preamble designating that the first word includes address information of one of the first and second stations identifying either the second station as the intended recipient or the first station as the sender;at least 3 bits of data to be transmitted from the first station to the second station, wherein the at least 3 bits of data are indicative of information other than preamble and address information; andno more than 16 address bits identifying a first three characters of one of the first and second addresses assigned to the first and second stations, wherein each of the first three characters of the one of the first and second addresses is an alphanumeric character.
