Currently there are 9 AERO-I 600 Baud GMSK channels on POR. Quite a bit of ACARS and CPDLC traffic along with the usual Call Management signaling units. These signals are huge as you can see from the “tightness” of the phase diagram shown below. The AERO-I decoder shown below is simultaneously decoding all channels using just one SDR. There are also some 1200 Baud AERO-I channels present on POR, something to look at next.
