You can go ahead and turn your IGate back on. I think I just figured
out what's happening! Those packets are something trying to use
Konverse mode to command a TNC, but the TNC is just transmitting the
commands as the payload of a packet. Consider:

The first packet is "K" to put the TNC into Converse mode.
The second packet is the command to set the Unproto to SXUQXT (probably
1/2 of the Mic-E coordinates) Via WIDE1-1,WIDE2-1.
The third packet is the other 1/2 of the Mic-E coordinate which is why
APRS.FI complains about it. The first half has been replaced by APX201.
It's definitely coming from the source and not being mucked about by
anything in between, IMHO. It's just a waste of good RF bandwidth until
he gets it fixed!
