Hey Bruce,

Considering he (K4COE) is beaconing every 30 seconds, in 5 minutes time 
he has sent an additional 10 packets. That would be really strange for a 
digi to hold that particular packet for 5 minutes, when he has sent that 
many more.

Looks like W4GPS-7 is a UIDigi firmware digi with a WX station 
connected. Possibly a problem with a tnc2 doing both? Too much data from 
K4COE?

Let me know if you need any logs or anything from down this way.
