A method and system are disclosed for communicating using both analog and digital transmissions on the same bandwidth. The method may include receiving a digital transmission and an analog transmission using a same/shared bandwidth. The method may include playing a digital audio of the digital transmission and an analog audio of the analog transmission using a same audio output. The digital transmission may include an identification code. The playing of the digital audio may include selectively playing the digital audio based on a match of the identification code with a stored identification code of the system and selectively squelching the digital audio based on a mismatch of the identification code with the stored identification code.

Digitally augmented VHF ATC communications

A method and apparatus for establishing a high data rate high frequency data link (HDR-HFDL) between aircraft and ground stations enhances the aircraft HFDL data radio to transmit at an HDR frequency assigned by a ground station and transmitted to the aircraft via the HFDL frequency assigned to the ground station. The ground station may select and transmit an alternate HDR frequency if necessary. In Phase I, existing aircraft subsystems and ground stations will be configured for HDR downlink only, but an aircraft subsystem may additionally receive HDR data packets if propagation conditions allow. In Phase II, dedicated HDR ground stations and enhancements to existing aircraft subsystems will provide for full HDR uplink and downlink capability. Dedicated HDR ground stations may select an HDR frequency from the band including the assigned HFDL frequency or transmit at an assigned HDR frequency.
