The digipeater DOESN'T transmit on a path of TEMP2-2; rather it RESPONDS
to it. If the alias in the digi doesn't match the path in the tracker,
it will ignore it.
Assuming your tracker will always hit your truck first, the mobile digi
should be set to an alias of TEMP. The tracker then needs to be set to
a path of TEMP,WIDE2-1 or TEMP,WIDE2-2 .
Paths are procesed SEQUENTIALLY. The truck will digipeat on TEMP.
Then "real" digis should hear the truck and respond to the next hop
(WIDE2-1 or WIDE2-2).
Note that if you DON'T reach the truck first (so the "TEMP" hop gets
marked as used up), then "real" digis will totally ignore your tracker's
transmission since they don't respond to "TEMP". This means for for
everyday use in town (where you are not using the truck as the first
digi hop), the tracker needs to be reprogrammed to use the normal path
of WIDE1-1,WIDE2-1 that normal digis expect.
