[Xastir] nws-stations.txt

[KC7ZRU - Tate]

Using lastnights CVS, running xastir here for I-gate duty.

OK - stuff from the NWS offices is gating to RF just fine (RIW, CYS).

File is: ~/.xastir/config/nws-stations.txt
Partial listing as an example:

IGUP
RIWWSW
RIWTOR
RIWNPW
CYSWSW
CYSTOR
CYSNPW
CQ
WY
KIDS
KC7ZRU-6
KC7ZRU-3
K7YE-3
etc

However, I'm *not* seeing the IGUP beacon being gated to RF.

Is there a 'valid' call sign check or 'minimum character count' that may
be 'blocking' things going to RF? Should it not be the 'first' listing
in the file?

TIA!!

I doubt you're seeing these:

Haven't we been here before? There's a routine in igate.c that
handles gating of NWS stations. If it's not NWS traffic, it doesn't
get gated to RF. Exception: APRS Messaging.

I think that routine would have to be changed a bit in order to allow
non-NWS traffic to be gated through. It shouldn't be a big deal, but
I don't think anyone's looked at that yet.

If you'll submit a feature request for that and provide an example
packet, I'll try to look at it sometime soon.

Doh!

OK - we may well have, Likely my CRS flaring up again.

Yea - at the *very* least, letting IGUP out would be a good thing.

Thanks Curt! Maybe an update to the README in the interim?

Sure. Tell us what specifically needs to change or get added to
README.1ST and Reuven or I will get right to it.
Looks like you were successful!

I'll do another development release on or about Feb 1st. If we
could get the README.1ST changes in before then it'd be good.

can someone explain to me please
what is NWS? and what is an IGUP beacon?
thanks

Don't know bout the IGUP, but NWS stands for National Weather
Service....that's of interest to those of us in the USA for the most part.
One of the "things" going on with aprs here is the ability of aprs software
to interpret and show weather warnings as issued by the NWS and the use of
their "shapefiles" to overlay a map and graphically show the area for which
the warning/alert is being issued. I think they use a yellow overlay for
"watches" and a red overlay for "warnings" and they usually are issued by
county (or several counties) for a specific amount of time.

More America'isms...

NWS = National Weather Service. Actual nation is not specified, but
is the U.S. Our weather server (run by Dale Huguely) converts
weather alerts into APRS packets that Xastir can then gate to local
RF. We have a file that specifies which area alerts to go local RF.
Those alerts then trigger various shapefile maps to pop up on top of
your regular maps and tint the areas of concern.

IGUP was explained to me during the last go-around with this. I
think it's a beacon sent out periodically over RF that let's
stations in the area know that they're within range of a functional
Igate.

[brenda]

are these related to the CW* weather stations (not morse) that are
dotted all over the globe?
i'm told they stand for "citizen's weather".
citizen of what, i'm not sure :)

Pretty durn Close - in fact close enough to not really require being
filled in, but me being a ham and all....

The IGUP beacon is a posit report sent into the APRS-IS by N7XUC in
Laramie, Wyoming. This came about, tangentially, as part of the HamHUD
project. 'Hudders' were curious to know if the area they were traveling
in had functional I-gate coverage or not. The IGUP beacons are sent
about every 10 minutes or so into the APRS-IS. An I-gate that's
configured to gate the IGUP posit from NET->RF is in essence
'advertising' that it has functional connectivity to the APRS-IS (since
that's the only way to get the IGUP beacon). The assumption then is, any
RF traffic sent near the time the IGUP beacon was seen will make it back
to the APRS-IS.

This IGUP beacon is seen as a third party packet on the RF side, so any
other I-gate seeing it on it's RF side will not gate it back into the
APRS-IS.

The IGUP beacon, though not as widely spread as other 'stuff', nor is it
assured the letters I.G.U.P. will communicate the same everywhere, is
usable in any country.

Nope. Those are non-ham weather people that are running usually
various windows packages that make their weather reports available
to others on the internet. Some of these put there data onto the
APRS-IS feeds.

I'll give you one guess...

I'm starting to think that we really don't know any other countries
exist...

Heh, I'm originally from Canada, which isn't all that far away, (now
living in Florida) and I could have told you that. But there are cracks
in the system --

According to the Weather Channel (a commercial television station; not
government run) all weather ends at the border. But, if you look
carefully at the radar returns, you'll see that some Canadian weather
does mistakenly get displayed. Oh, and Canada is blamed for any cold air
that approaches from the north. Other than that, it doesn't exist.
