Zusammenfassung:	A method of fade recovery in a digital message transmission system in which data is encoded into code words, formatted into frames of a batch and transmitted in accordance with one or more transmission formats, and a synchronization code word, indicative of the transmission format, is inserted at the beginning of each batch, the method of fade recovery including energizing a receiver for a first predetermined time period and storing any signals received during the first predetermined time period, analyzing the stored signals to determine if the stored signals being transmitted is in one of the transmission formats, and if so, maintaining energization of the receiver in predetermined time increments for up to a maximum of a second predetermined time period and checking if any of the stored signals associated with each such time increment conform to at least one of the transmission formats.
