OK, so the TNC for N9JY-1 is the Tracker 2. Are you seeing the garbled 
data right in the UI-View terminal window with the filter set to exclude 
Internet traffic?

I know that the KPC3+ in KISS mode introduces delays after a week or 
two. I've witnessed it, but have been for ages been trying to document 
it properly for Kantronics who is supposedly testing it themselves. It 
is possible that the problem is not "KPC3+ specific" but anecdotally, 
and in my own observations so far, it would appear to be.

So the T2 is acting as a WIDE1-1 fill-in digi, isn't beaconing itself, 
and that UI-View is running as an IGate. Again, I would ask if you see 
the corrupted data right in the terminal window. You could even take 
UI-View right out of the loop and just run it with a plain jane terminal 
program connected to the T2 to see you can see any corrupted callsigns 
or other data.

How much RF is floating around near the T2? Any chance it's getting 
swamped with RF? All the antennas have a good SWR and are physically 
away from the T2 some distance?

Looking at aprs.fi, I see 0WJY-9 near you and gated by N9JY-1. I presume 
this is one of the garbled callsigns. Also RLOV, 44OOV and K40S4M. 
0WJY-9 is useful because you hear it direct. The others that I looked at 
had gone through a digi before they got to you, so the corruption could 
have taken place elsewhere. You need to prove whether the errors are 
being caused by your equipment / software or if it's taking place before 
it gets to you. There's also the possibility of corruption taking place 
before the data is transmitted by the originating station, but it would 
be quite a coincidence to see multiple stations with the same problem 
all in the same geographic area.
