[aprssig] Dumb tracker question

[Earl Needham]

A friend of mine runs a tracker as W5ROY-15, and when I see him on my
HamHUD, his heading is usually incorrect, sometimes by as much as 180 degrees.

Am I remembering correctly that some TNC's do something odd like that? Or
could it be something else that's causing this?

Thanks,
Earl
