Paths are used sequentially (with no regard to the T2's which can do
pre-emptive digipeating) so as long as N7FMH-9 is within earshot, that
will work. If you set N7FMH-9 up to respond to WIDE1-1 and run a path
of WIDE1-1,WIDE2-1 (or WIDE1-1,WIDE2-2  if you really need it) then
it would "work" whether N7FMH-9 was within earshot or not.

True, but if your HT went somewhere else, using a generic path would
make it compatible with the rest of the network without a specific digi
being nearby. Still, if your vehicle with N7FMH-9 is always nearby, it
should always work.

I don't think it will be a very valid comparison in your area. You say
that you can't always get to a high digi from the 40W tracker in your
vehicle, and that it often needs help from a digi at your home QTH.
Running the HT at a fixed rate will probably get more position reports
to an IGate just because it is beaconing all of the time. The 40 W
tracker using SmartBeaconing will only beacon when it needs to... every
few minutes at highways speeds and one or several times when it turns a
corner, and down at a 10-30 minute rate when it's sitting still.

If there are no other APRS users around you, beaconing often won't have
any adverse effect because no-one else is sharing the frequency with
you. In areas with dense amateur populations and thus more APRS users,
sharing the frequency becomes much more important. It sounds like what
you really need is more APRS infrastructure around you. That might mean
one more digi or several, and possibly an IGate if the nearest IGate is
already several hops away.

Regardless, test away! Presumably things like transmit delay and
deviation aren't limiting your success.

>> I'll be watching! Good luck with the experimenting.

I used the "prefix" filter and added p/N7FMH but haven't actually seen
you move yet. You may have actually been on my map, but I was looking
for a track and didn't see one. However, looking at...

http://aprs.fi/?call=N7FMH-7
http://aprs.fi/?c=raw&call=N7FMH-7&limit=100

I see that N7FMH-7 made it to an IGate on Aug 15 at 20:52 about 27
times. Every time, N7FMH-9 was the first used digi. Five times, you were
gated by N1IIC-3 without needing any other digis. The rest of the time
you were also digi'd by KQ1L-1 before being gated except once you were
digi'd by W1WQM before being gated. That could mean you only beaconed 27
times, or it could mean that you beaconed a whole bunch of times but
were only digi'd by N7FMH-9 27 times.

For comparison, N7FMH-9 was heard as recently as today and is currently
on my map...

http://aprs.fi/?call=N7FMH-9
http://aprs.fi/?c=raw&call=N7FMH-9&limit=1000

and was gated a whole bunch more times... apparently about 400 times
since Aug 15. I'm guessing that your slow rate is 10 minutes. That's
what I use, but I don't (currently) beacon after the engine is turned
off. Studying the paths used will help show where the digis are around
you.

PS - you can shorten your beacons by e.g. only sending your email
address every 10 transmissions. If it doesn't change, it isn't really
needed every transmission.

I've got to admit that it's pretty nice around here. You won't find any
lack of digis or IGates anywhere in the "Seattle - Vancouver - Salt
Spring Island" triangle!
