UI-View will display the digipeater on the map with a star and an S overlay 
at all times. The sequence of events is the UIDIGI will beacon its position 
using the digi star with an S overlay using the following beacon text 

Beacon1Text = !3438.07NS08630.74W#PHG5630/W2,ALn    Huntsville Alabama

Shortly therafter, the third party beacon as defined earlier will be 
transmitted. As soon as UI-View receives that packet, the digipeater is 
highlighted with the square box around it. Whne I seen the square box around 
7 digipeaters, it was obvious something was not working correctly and the 
third party format was changed to avoid this problem in UI-View.

The "BT 3" command is a UIDIGI remote command to program the Beacon3Text as 
UIDIGI supports 3 separate beacons that can be transmitted at various times. 
The ambiguous position does not change the end result as we had one 
programmed with the full position and observed the same results..

These were the setup conditions:

Beacon1Text = !3438.07NS08630.74W#PHG5630/W2,ALn    Huntsville Alabama
Beacon2Text = !3438.07NS08630.74W#PHG5630/W2,ALn    Huntsville Alabama
Beacon3Text = }146.940->APOBJ:!3444.27N/08631.98WrPHG7730 PL 100.0 Net Th 

Beacon1Path   =
Beacon2Path   = WIDE2-1
Beacon3Path   = LOCAL
AuxPath          = AL2-2

Beacon 1 goes out every 10 minutes via no Beacon1Path.
Beacon 2 goes out every 29 minutes via Beacon2Path.
Beacon 3 goes out every 10 minutes 1 second via Beacon3Path.

Weather data received from the serial port is sent via the AuxPath every 3 
minutes in the format:


Once the third party packet format was dropped we never seen the problem in 
UI-View again.

I hope that helps explain the conditions a little better.
