Good Idea!  Worth a test!
1) It works via the fill-in-home-digi (with or without callsign
substitution)
2) But if a normal digi hears it first, then it will be accepted under
the WIDEn-N algorithm and therefore if that same digi hears
a subsequent copy of it, it will ignore it!

WOW!  Am I missing something or is this the Holy Grail?
It depends on the exact implementation in the KPC-3 as
to whether it cares or not about which WIDEn-N field it
is addressing or not.  Definately worth a test!!!
