In below observation, I can see it decoded in AX.25 frame, but the frame structure is not visible in data the ground station decoded. How does it getting data in AX.25 frame?
https://network.satnogs.org/observations/10582647/
To put more in detail, it decoded SC2314 (53 43 32 33 31 34), R2ANF (52 32 41 4E 46) but I can’t find them in nowhere in decoded data.
Any help will be appreciated.
R2ANF is A4 64 82 9C 8C
SC2314 is A6 86 64 66 62 68
You have to shift it 1 bit.
