In short there are 3 default substituting aliases, relay, wide and
trace, wide and trace are for high digis, relay is for home digis (a
stuping stone for mobiles)
Next there is widen-n where n is between 1 and 7, it is not substituted
but the seccond n is counted down to 0 and the h bit is set when 0 is
reached.
Third is tracen-n again n is between 1 and 7, every time n is counted
down the digi callsign is inserted before tracen-n with h bit set and
once 0 is reached the h bit on tracen-0 is set.

replacing relay with wide1-1 and stop using wide and trace is needed for
getting around a bug in the kpc-3 where dupe checking on aliases wasn´t
handled right.
Europe doesn´t use kpc-3 digis but software digis like ui-view digi_ned etc.
limiting to 2 or 3 hops makes sence in highly populated areas with digis
on mountains but most of europe is flat and population is spread out
evenly and unlike usa aprs is used long distance with the emphesis on
the rf network rather then getting into findu.com.
