Abstract
A data link radio system onboard an aircraft communicates with a plurality of ground stations that employ either an analog communication protocol or a digital communication protocol. A database contains information related to each ground station and its respective communication protocol. A transceiver communicates data bidirectionally with the ground stations. A receiver scans for an alternative ground station to use as an alternative to an active ground station with which the transceiver is communicating. When the active ground station becomes unavailable, the transceiver is automatically reconfigured for the analog or digital communication protocol used by the alternative ground station and then begins communicating with the alternative ground station.
