Not that it's mandatory, but FWIW, KC2UFG hasn't sent a position report
in the last year or so. It may not even be transmitting actual APRS

Hopefully it was a mistake, but time will tell.

Now that one is APRS. What a stupid path! At least out over the
Atlantic, it's limiting the effects to potentially half as many APRS
users than if it had been over land.
Hmmm... I wonder why it has TCPIP in the path for some packets? Is
someone gating it back out to RF as well?

I couldn't agree more. They are doing some fun stuff, but with a really
stupid path and beacon rate. I'm sure it's done through ignorance
instead of malice though. Ummm... are Bob's chasers in a really fast
boat? hi! I wonder if it will come down at sea or in NL? Some sealer
might accidentally mistake it for a seal pup!
Anyway, with that out of the way, I'll put my feet up and have some fun
and watch its path... err, route! Hmmm... any chance this is a really
long duration flight? If it ends up in British airspace, someone from
OFCOM might call out the RAF to shoot it down!
