Good observation, but they are supposed to be sending 
out their APRS Position beacon once every 10 minutes 
locally, and in most cases that is using a DIRECT path
so that it doesnt QRM 3 states.

Setting the local POSIT to every 10 minutes is -not- the
simple BEACON EVERY 10 setting.  It takes a little 
shrewdness using at least 3 of the LTPaths and 3 LTexts
and 3 BLT's as detailed in:

http://www.ew.usna.edu/~bruninga/aprs/digi-rates.txt

Then it sends out a POSIT once every 10 minutes DIRECT
and out ONE hop every 30 minutes and 2 hops every
hour without any duplication.

thanks.  Bob, WB4APR
