AX.25

I discovering some ax.25 packet radio floating around on 145.010MHz. I connected my Btech APRS audio cable from computer headphone/mic to the Quansheng, and piped the audio into multimon:

$ pw-record --channels 1 --rate 22050 - | multimon-ng -t raw -a afsk1200 /dev/stdin

Here’s some of the traffic I decode:

I need to find a terminal program for Android (BPQ Term?), and read more about the anatomy of an ax25 packet.
