Mr. Baxter did not write that, but me,
talking only about crossing an ocean with APRS gear, including GPS, and

Subject: [aprssig] New-N Paradigm APRS Digipeater statistics
Annual report of APRS digipeaters worldwide:
Now, almost 85% of all digis worldwide support the New-N paradigm. In the
last year, the number of fully New-N ("S") digis has trippled to almost 50%
of all digis. But still almost 26% of the old WIDEn-N ("N") digis have not
been upgraded to all the improved effiiencies of the New N paradigm though
they do still support WIDE-N users of the new Paradigm.
New-N-Paradigm Digis:
S digis 680 was (206) New-N's that support SSn-N (tripling)
L digis 80 was (80) New-N's (should become S's)
P digis 18 was (13) New-N Paccomms
1 digis 40 was (22) New-N one-hop digis
There are 15 "F" digis that should be "S" digis because the "F" idea
dead-ended and we decided it was better to just make them "S" digis because
we eventually found a pretty good fix for the the 8.2 KPC3 settings.
Similarly the "L" digis were also a dead-end idea and they should also be
"S" digis.
Old style digis:
N 460 was (620) Old WIDEn-N's that flood and bad settings.
T 120 was (112) obsolete PacComm Trace digis (need new settings!)
U 130 was (150) UIDIGI ROMS needing updating to "S" digis
D 60 was (88) DIGI_NED software needing updating to "S" digis
R 90 was (97) obsolete RELAY only digis (need to become "1" digis)
W 12 was (26) obsolete WIDE-only digis (all are out of USA)
This shows very good progress on the New-N digis, but still there are those
frustrating 120 Paccomm Digis "T" out there that can easily support the
New-N paradigm with only a remote-sysop logon and new settings. THese
should then become new "P" digis, showing they support the New-N paradigm.
I also see over 970 showing a type of "/#" with no overlay but 90% of these
are all outside the USA, so I cannot really criticize thse for not showing
an overlay character to show users what they do...
The "N" digis also need updating:
Remember, Altough a New-N user gets through those old "N" overlay digis,
those digis are still not helping to improve APRS network operations.
These advantages of the New-N paradigm are NOT being supported by the old
"N" overlay digis:
1) Paths are not traceable
2) Digipeater type is not identifiable
3) User path settings are not shown in the digi's beacon
4) Inefficent DIGI beacon paths are being used (high QRM)
5) Inefficient DIGI beacon rates are being used (High QRM)
6) Local info is not provided on local voice contact info
Here is all abou the New-N paradigm:
http://www.ew.usna.edu/~bruninga/aprs/fix14439.html
All of the advantages of the New-N paradigm are also advantages in Europe
and elsewhere and the only difference between the USA New-N paradigm and
the European version is that RELAY is still allowed in Europe. I suggest
an overlay of "E" for all those European digis that want to go with the
New-EU paradigm.

Subject: RE: [aprssig] Track of road trip
Great story and great results, Joel! Thanks very much for the fine report!
Excellent to hear your _experience_ shows "certainly more than two hops -
even in remote areas is unnecessary" and the North American mobile digipath
(WIDE1-1,WIDE2-1) is working so well now. We all still need to focus more
energy on "outreach" toward other APRS users and digi sysops (beyond "the
choir", the readers of APRSSIG) with this good news.
In North America, we're still only part-way through this major improvement
to the VHF network. We can all help. We can re-focus on getting it done
everywhere, and press on. The VHF network will work so much better _for
all of us_ with everybody helping each other with modern settings. It only
takes a few settings updates from each station to operate courteously in
the 21st Century.
If there's a digi near you with a antique "N overlay" on it's map symbol,
keep talking to the sysops. Maybe it can help to let them know that their
fine digi callsign will appear in _every_ packet if they simply update
their settings. And with updated settings, they'll courteously start
allowing _the second_ hop of the "new" standard mobile digipath too.
If you see a packet containing RELAY or WIDE or TRACE or TRACEn-N, keep
talking to the operator. Help them improve their digipath (and/or
transmission interval) settings. They're not deliberately being
discourteous, they just don't know any better yet.
As usual, the problem is only _not enough_ communication, and the solution
is simply _more_ communication.
As Joel N7XUC's report reminds us, sharing is just plain fun too.

I think trying to put a digi *in* an airport would be most unwise. As a
commercial pilot I probably have more dealings with airport security than
most of you and I can assure you the "braintrust" at the DHS/TSA would have
a cow even thinking about it. Besides for that, most people running around
the airport are pretty busy trying to find their bags and a rental car. All
that being said, why not a digi NEAR the airport you can get from the
shuttle taking you to your car.

Here is the link for my last road trip. Good coverage except for the
eastern part of Colorado (more jack rabbits than people out there).

That very well could be - I was hearing some packets through there.

I see it not that different from the person listening to the ham operators
on a shortwave receiver a few decades ago, and deciding that they wanted to
be part of the conversation.
