The data can certainly be treated as 'tainted' inside Xastir and kept from
being gated. Just plotted.

Subject: [aprssig] Routing
Hi All,
I seek confirmation (or otherwise) that my APRS routing is/will be set
up correctly.
I run Xastir as an Igate and on the same Linux box I run DigiNed. Xastir
and DigiNed talk to each other via a psuedo-tty link.
DigiNed handles two radio ports and an axudp link to the Windows machine
on the LAN. DigiNed has the callsign vk2tv-10 and the alias WIDE1-1.
Xastir has the callsign vk2tv-4, not that that's relevent here.
My routing in Xastir (and UIView) is set to WIDE1-1, WIDE2-2
Currently there are no other APRS digis within 350km of here so it wouldn't
matter what routing was used, for now. However, there is the possibility of
another digi being established 40km south of here and, hopefully, activity
will breed activity. I figure we may as well start out on the right foot
with routing to avoid having to make changes down the track.
My best guess is that the WIDE1-1 alias in DigiNed is appropriate given its
small coverage footprint.
In addition to the possibility of another digi down the highway a bit, I
will set up a local digi at a better location (and seriously reduce power
here to sufficient to access the new local digi). Should that digi become
WIDE2-1? It, and the prospective additional digi down the road will be able
to hear each other. Neither system will have large coverage, their location
heights being at best a couple of hundred metres. Their footprints will
slightly overlap.
The configuration would be like this....
vk2tv-4........ttylink....... vk2tv-10........ Digi1............
Digi2......... other users
(WIDE1-1, (WIDE1-1) (WIDE2-1) (WIDE2-1)
WIDE2-2)
Does that look right?
I await your considered verdict.

As you mentioned, if there is no other digi within 350 km, it's not going to
make a lot of difference how you set up either the IGate or the digipeater.
For that matter, it wouldn't make any difference if you beacon with no path
at all unless the IGate or whatever would be able to reach out further via
your own digi.
With that said, thinking in terms of recommended settings in North America,
no fixed station should have WIDE1-1 in its path. I would suggest that you
set the digi up as a WIDEn-N digi in anticipation of moving it to the better
location even if it is only going to be up a few hundred metres. Everything
else you have in "the shack" could go out with a path of WIDE2-2. For now,
any beacon you send isn't going to make it any further than it can be heard
direct or via your digi, either at its present location or when it moves to
its new home. If the digi 350 km away can hear your digi, you will get one
more hop. I don't know what kind of terrain you are dealing with, but that's
quite a bit of distance. Either the distant digi hears you or your digi or
it doesn't.
If another digi does happen to go between your digi and the distant digi,
you could access coverage and see if you want to go out with a three hop
path (or whatever) or a two hop path. In an ideal world (again thinking in
terms of North America) there would be no-where more than two hops from an
IGate. Realistically, there will be places in your neck of the woods as well
as over here that will either have no coverage or will be more than two hops
from an IGate. Paths, at least until/if we move to NSR (no source routing),
can be adjusted accordingly to either get the desired number of hops or to
reduce it if levels of traffic demand that paths need to be shortened. It
doesn't sound like the APRS frequency will be overly-busy in your location
for a while - hi!
The reasoning for not using WIDE1-1 from a fixed station is so it doesn't
trigger "all" of the WIDE1-1 digis around it when the fixed station
supposedly with a better antenna than mobiles should be able to hit the
local WIDEn-N digi without any help. In your case, you don't have a dozen
WIDE1-1 digis around you, so it doesn't really make any difference. It would
also be nice if folks that were set up for APRS use "in town" didn't have to
change or adjust settings when they were in your vicinity. It would work the
other way around too if you didn't have to change your mobile settings when
you went into town.
I'm sure it has been mentioned on the list before, but is VK-land going with
WIDEn-N digis... i.e. have RELAY, WIDE and TRACE/TRACEn-N been
obsoleted there?

I haven't seen anybody post to the list about this yet.
Icom has announced a new mobile rig, the IC-2820H.
http://www.universal-radio.com/catalog/fm_txvrs/2820.html
-2m/70cm true dual band operation, separate displays and controls V/U V/V U/U
-Alphanumeric naming of channels (Why have manufacturers left this feature
out for so long in dual band mobiles? Not seen since the FT-8500...)
-Optional UT-123 module gives D-Star capability with built-in GPS receiver
for D-PRS
-Two antenna diversity reception capability
Looks like I'll have to bust open my piggy bank. Price TBA.
Too bad it doesn't have any built-in APRS capability.
Yaesu? Kenwood? Where are you?

Mark

Although it doesn't have built-in APRS, it is APRS capable. It does have a
1200/9600 baud packet connector and you can run APRS on one band, and FM or
D-STAR on the other.
I have been using D-STAR for a while and my main focus has been APRS over
D-STAR. It works extremely well. In my opinion, APRS over D-STAR is much
better than APRS over AX.25.
In addition to using AX.25 on 144.390 MHz, my UI-View32 station (KC5ZRQ), is
also using D-STAR on 145.670 MHz. I also have a station, KE5MBS, setup on
D-STAR, for the local RACES organization.
I have two Internet gateway stations in my town. KC5ZRQ-1 for APRS and
KC5ZRQ-2 for D-PRS. They bridge the gap between D-STAR users and APRS
users, providing 100% interoperability.
SmartDigi, for the TNC-X, provides APRS and D-PRS interoperability with the
need for any type of gateway.
I look forward to the Icom IC-2820H. I think it will provide users with the
choice of using either APRS, D-PRS or both.
John, KC5ZRQ

Why?
I haven't looked at D-Star beyond the price; they're noticeably more
expensive than the Kenwood APRS rigs, and as far as I can tell they don't
have any sort of APRS-type application built in, which means more external
hardware to do APRS.
