This is the standard Digi_ned satellite object.  Once a person learns
what to look for it is extremely useful in the local area.  These have
been used for years and years.  I'd always thought that the APRS-IS
was filtering them since there would have been so many local
instances...  That's probably wrong on both ideas - the filtering and
the many.   Turning on local filtering by adding "RFONLY" to the path
is likely the right answer.

I really miss seeing them in the area and am looking forward to
getting that running again RSN.
