[aprssig] Object DENNI_ato Cannot Be Seen on RF Path

One good thing about owning / running the equipment is that it can be
reconfigured at will and to meet the needs of the situation.

In an emergency such as this, when the affected area is so big that the
existing path doesn't begin to get into the area, a temporary increase in
the path of the igate digi might be in order.

For example, if I were an igate (I wish!) and was the only weather igate
still working in Washington and something big was heading for the eastern
half of the state, I would probably use this path to get info over to that
area:

WIDE2-2,MISSION,WIDE2-2

That doesn't spam the entire area (ok, perhaps it does spam a lot of Western
WA) but any packets that do get to the big gun on the eastern side of the
hills (the MISSION digi) would then get sent out to a decent area (at least
until something happened to Mission and by then I'd probably be off the air
also<G>).

So pick a decent digi 1/2 or 1/4 way or so into the area that needs the data
and do a temporary routed path that gets the data into that area.  Then,
once everyone picks up the pieces, do something more permanent.

Or, if everyone needs the info...

WIDE2-2,WIDE2-2,WIDE2-2

That way, even if the digis in the area are trimming paths larger than 2, it
still gets out and about.

Geoff:

I am still gating it here in from my station in Pinellas. I think you used
to see it originating from my station. Unfortunately, with this new wide
routing, I don't think it's making it much further than Polk County any
more.

If you want some hints on how to make it happen, please feel free to shoot
me an email and will go over it. Unfortunately, I think it means the guys in
the middle might get the bulletins & position statements twice.

I'm with you - I think we've done more harm than good with some of these
changes implemented. While this might have been a good solution for the NE
corridor or California, I think we've crippled the network in areas such as
our own.

Here we are, with Hurricane Dennis offshore a few hundred miles due west of
Orlando, Florida, and no posted storm location can be seen
of it via APRS RF links.   Here is a perfect tactical application
that has fallen flat!      

I am beginning to understand Earl Needham's concern over being 
isolated with the new path length limitations to APRS.  From Central Florida
we used to see these kind of RF postings.  Now all we can see is 22
stations, with only a single Wx station showing on the  
the Gulf coast, as seen from Central Florida.

One can connect to the internet and see object DENNI_ato uplinks to 
APRS by NHCTCM via the servers.   This is great for people who have
high speed internet connections.   When power is lost, and the lines
and down, the people within the area of most concern will not be able to use
RF APRS to see the center of storm as posted objects. I believe APRS has
lost the tactical feature it once had with a good RF network in place.
