Every once in a while a youtube video is uploaded with telemetry on the audio track. This can be demodulated though every system is a little different.
For this chase:
miami chase on youtube
I have decoded this output that I have uploaded on pastebin
decoded output on pastebin
using this web page as an example
helicopter telem decoding
I am trying to pick out the position data. Here is a sample field:
AN 25 5195
BW 080 1920
C044
D083
E000841
K00002
L0438
l01201
Miami lat/lon is 25.830500 -80.180374. No obvious mapping is coming to mind but I figured I would do a post on the long shot someone sees a pattern, The pastebin has more data packets. The BW field never changes. I guess it is the L and l fields but the position data doesn't make sense.
