Please, please do not do that!  Using a dupe-
generating path like WIDE,WIDE is not only
bad, but it is BAD based on the number of digis
that hear the first instance.  At altitude, EVERY
digi hears it and EVERY digi then generates a
dupe that then EVERYOTHER digi then 
duplicates.  You end up with every digi repeating
the packet 3 to 5 times!

This problem pops up every year as newbee's
launch balloons without first thinking about the
consequences of their paths at altitude.

ALMOST EVERY digi has always supproted
WIDE2-2.  It works.  Use it.  It does not have the
altitude dupe problem because all digis do perfect

And if the chase team is not within two digis of
the landing site, then they have been asleep...
