[OZAPRS] Fw: Fill in Digi

[Geoff]

For a quick overview of the way APRS digipeating works,  take a look at 
http://vk2.aprs.net.au/digipeaters.php

If you are in VK2,  the recommended settings for a mobile setup are:
Mobile - WIDE1-1,WIDE2-1   

WIDE1-1,WIDE2-1 will digipeat your data through 2 digipeaters, which in
99%
of cases is enough to reach an IGate.

WIDE1-1,WIDE2-2 will digipeat your data through 3 digipeaters, which
should
only really be done if you are out in the sticks and the nearest IGate is
3
hops away   

Any stations in the Nowra area at the moment should use WIDE1-1,WIDE2-2
due
to the current issue with VK2AMW-4 digipeater.  The reason is that the
current path to the IGate is:  VK2AMW-4,VK2AMW-1,VK2US-1 = 3 hops.

Hopefully the upgrade of the remaining digipeaters in VK2 will be
completed
very soon and some significant improvements to the path reliability will
be
seen.

Regards,
Geoff  VK2XJG

Perhaps some of our learned ones could explain to us novices the
implication of the numbers associated with the wide statements i.e.
what's the difference between wide 1-1, 1-2, 2-1, 2-2 etc. Maybe some
people are setting up their systems incorrectly simply because we don't
know any better.

Perhaps someone could also explain how this whole path thing paradigm is
supposed to work. It's probably quite simple but I'd rather have the
official answer than keep guessing how it might work.

I know in the big smoke there are so many 'repeaters', or whatever they
are called in the APRS world, there appears to be no great need to know
what path and how, but for us, who live in the country on the wrong side
of a big hill getting a path to an IGATE can sometimes be difficult.

A "normal" digi would usually have wide-area coverage. A "fill-in" digi 
would provide a mechanism to access the wide-area digi from, say, a 
shadow area within the wide-area digi's coverage.

In old parlance a fill-in digi used the intuitive RELAY alias. Under the

new, more channel efficient scheme, it would be WIDE1-1
.
A home station with a good path to a wide-area digi might use WIDE2-1 in

the path. For a mobile, the path, typically, be WIDE1-1 WIDE2-1 to take 
advantage of any "fill-in " system that might exist.
