I took some screencaps of two programs I use occasionally with a radio.
PDW can decode
POCSAG,
FLEX,
MOBITEX, HERMES and
ACARS digital information.
ACARSD decodes ACARS only. Both programs are free (as in beer). The signal from the radio is connected to the sound card and the application decodes the audio. ACARSD is available for Linux as well. It also downloads photos of identified aircraft if available, as shown in the pic. I can't get the map feature to work unfortunately
PDW decodes POCSAG from the 148 MHz frequencies. I've obscured some identifying details.
PDW decodes ACARS on the international frequency of 131.550 MHz AM
ACARSD decodes ACARS, same freq. Excellent program. Main window.
ACARSD alternate window
