There is a UI-View add on, APRS Network Analysis that will do this.. It
has been utilized quite a bit by several sysops around the country, and
they link to each other's out of area web pages..

The above is an example of a woefully out of date digi. Despite a few very
polite e-mails using the address shown in the beacons, nothing has been
done to get this digi updated. The really sad part is that this operator
reads and posts on the APRSSIG. It is a mystery why some people don't want
to make the simple changes needed to make APRS a useful tool especially
since, like Bob said, getting things updated to the new WIDEn-N paradigm is
a win-win situation.
In an e-mail conversation with the operator of this particiular digi, it
was observed that he seems to think that it's fully compliant with the new
paradigm except for an obsolete beacon string. Unfortunately this is not
the case:
* Tests have shown that it does not do path tracing of WIDEn-N as the new
paradigm states. It supports WIDEn-N, but only in the old non-traceable
way.
* Tests have shown that is still digis on RELAY, which is obsolete and only
encourages mobiles and other users to not update their systems.
* It digis on WIDE and TRACE, both obsolete -- same comment as RELAY.
* The beacons are going out with a three hop path. Since this is a digi,
that's equivalant to a mobile station using a four-hop path. These beacons
are providing QRM in all of the surrounding states -- especially the
bulletins which provide no useful information. (No one 300+ miles away
cares that the radio was replaced with a temporary one 12 months ago.)
* The type of TNC/software is not shown in the destination field.
* Nor is the proper overlay being used.
* Nor is the proper symbol being used -- It's advertised as weather station
but does not send any weather data and has not for a long time.
It is such a shame to see this digi go to waste because if properly
configured it would be one of the best in the state of Missouri. Polite
e-mails have been exchanged with the sysop but no action has been taken.
It's sad because these changes can probably even be made remotely in just a
few minutes, so there wouldn't even be a need to drive to the site. It's
unfortunate that travellers passing through this and similar areas
(Atlanta? St. Louis?) are subjected to a broken network.

Thanks Jerome,
Your enumeration of each of the New-N features is helpful so that maybe
people will see how all of the details of the New-N paradigm all work
together to greatly improve the APRS network for the users... WB4APR

Subject: [aprssig] APRS Coverage in Key West
I'll be traveling down to Key West next month and was trying to figure
out how much APRS coverage there was down there. Looking at the current
IS stream I'm not seeing any digipeaters or anything down there. Can
someone confirm this?

If you can use VHF APRS on _this_ stretch of coastline, you can use it about
anywhere.

P.S. W6TAR-7 thru W6TAR-12 are new N1VG OT2 T2-135 modules for the Alinco
2m mobile radio. http://map.findu.com/W6TAR*
Mobiles on the Marathon course will use their routine settings:
WIDE1-1,WIDE2-1 while mobile on 144.390 MHz.
UI-View32 display stations on the course will use "Setup,Edit Translations"
to label moving stations with tactical callsigns for local display.

I think it has a WIDE,WIDE,WIDE,WIDE system because the TNC's at remote WX
stations are acting as the digis, and to upgrade to New-N would require new
hardware. If they simply made the old TNC's WIDE1-1 only, then they would
me minimally New-N compatible, but only for 1 hop.
Travelers, then, only going one hop will not meet a lot of new folks.
Their primary mission is to get the WX data to the Hurricane Center in
Miami, so there has not been a lot of incentive to upgrade. But for
disaster response, I would think that upgrading to the higher network
efficiency of the New-N system could be justified for incoming first
responders with APRS....
Fortunately, running W,W,W,W on a linear string of digis in such a sparse
area does not have the disadvantages of dupe multiplication that it has in
2dimensional systems elsewhere. SO maybe try W,W,W once you get south of
Miami. I hope the rest of Miami northward is New-N, so that a W,W,W mobile
doesn't trash up the Miami area too...
Kibitzing out-of-area and could be sticking foot in mouth..

Does the Uiview DF-Plot add-on also do the basic APRS OMNI-DF overlaping
Signal Strength contours?
The technique noted above depends on properly equiped mobile DF units with
lots of equipment. I basically gave up on that way back in the 1995 time
frame, since we never had the equipment or the people when it was needed.
So we added OMNI-Dfing to APRS in hope that APRS could concentrate on its
knowledge of position of -everyone- and what-they-hear and Antenna-Height
Range as a much more reliable come-as-you-are method of signal origination
localization. Too bad it was not universally implemented in all APRS
clients so that we could be doing this at the push of a button within
seconds of hearing a request for signal info.. :-(
Uiview doesn't even provide the fundamental antenna height and coverage
info without people loading an add-on. And without being able to see
instantly what approximate area coverage each home station has, then it is
hopeless to make any sense out of Uiview stations.
Checking the DC/Balto area and 235 stations on the air, only 5 Uiview
stations are transmitting their PHG data. The other 60 it is impossible to
tell if they have a good station/antenna hearing out to 50 miles, or
hearing out to 1 mile using a rubber duck in the basement. They all look
the same.
And even if these people did want to make an OMNI DF report, Uiview without
the add-on has no input box for making the report and no PHG data on which
to base it.
So that is why APRS as a group still cannot do simple signal localizing
which can work so well and is so easy to do. That is why I give up and
ask that at least someone implemnet it in a browser application so that we
can really nail these signals as it would be so easy to do... Surely
someone might be looking for a neat project that will revolutionize HAM
radio Dfing...
