Re: [Xastir] Wx alerts update
Hello, can you give me the server adress to connect and observe your packet. If you post a packet with 1 hour dead line and you need to post a special packet to cancel the fisrt one and then you can post a new one. This mecanisme appear like an update. In my tests for France we think for a bad link RF. If you loose a packet because you receive them in RF you don't receive a fresh information. For that we take information from weather service when they update them, généraly 1 per hour. This info was send to time per hour with limited valid time. 73 Arnaud 2012/6/20 Apostolos Kefalas sv1...@raag.org Hello guys, the last few weeks i have an up and running weather alert server for Greece.

Hello,
Hello Arnaud,
can you give me the server adress to connect and observe your packet.
I could give you the address but you won't see anything since there are no
alerts at this time, also the application is running only when there are
active alerts and then refuses inbound connections. But you can see for
example the packets below:
ATTHWSAPRS::NWS-ADVIS:201900z,WIND,GRC423{K0kAA
ATTHWSAPRS::NWS-ADVIS:211100z,WIND,GRC423{KASAA
If you post a packet with 1 hour dead line and you need to post a special
packet to cancel the fisrt one and then you can post a new one.
This mecanisme appear like an update.
I could do that, but I was wondering if I could somehow avoid the extra
cancel packet.
In my tests for France we think for a bad link RF. If you loose a packet
because you receive them in RF you don't receive a fresh information.
For that we take information from weather service when they update them,

Re: [Xastir] Wx Alerts
Excellent topic. Here are my thoughts on it. I like the idea of the weather alerts coming through. But we seriously must lean on local igates to limit what and how things are gated to RF. On my computer I'm happy to see it all (it'll be self-limited by what map I have open). But when I'm mobil I hate getting messages (weather alerts) for DX (NYC, Buffalo, and I've seen further). I want the county or two around me. And it doesn't need to be sent every 10 minutes either, not unless it's super urgent. That said... I'm happy to help, and I'd love to be able to igate local stuff via Xastir into the local RF stream. But I'm only going to do it if I can figure out how to configure it for a relatively small set of stuff and with timing more like once or twice an hour. Thanks.

Re: [Xastir] Wx Alerts
I wasn't here then, but I suspect the complaints were targeted at the data source, but were in fact the problem of IGate operators that configured their IGates to transmit alerts for a much larger area than their reasonable RF footprint. It's easier to shut down the source than to fix a few (tens? hundreds?) of IGates that might not have even supported sufficient filtering capability to even stem the tide of messages. The weather alerts as specified at http://www.aprs-is.net/wx/ don't actually include any actual APRS-aware location, but only an NWS office designator. You'll note that the t/n (NWS weather type) filter isn't supported in the .../call/range form. So, there's no defined way to get local NWS alerts from the APRS-IS feed for gating to start with. The filters are all-or-nothing. I'm trying to figure out a way to support a filtered gating of such information for any IGates running APRSISCE/32 and they'll probably be based on the NWS office being explicitly specified in the filter component(s).

Re: [Xastir] Wx Alerts
OK, I have corresponded with the authority. According to Pete Loveall, the server that issues the Wx Alerts is working fine. He found the Tornado Warnings for this area in the logs. There were two warnings. It appears that there was a problem with one of the warnings, so it would not have been interpreted properly. The other warning appeared OK, but as luck would have it, there appears to have been an Internet connectivity problem during that time, so it was not received on Xastir's Internet Server Interface.

So, the object starts at 48 23.10N 115 33.90W
Line type 'j' (Green Solid)
Object type '0' (Closed Polygon) Interestingly the points close the
polygon anyway and I gather it's NOT supposed to be filled?
Scale 'I' or 73 which is 0.01 units per increment
NH = 78/72 or 0/-6 increments which I thought was 48 23.10N 115 30.30W
which is indeed EAST of the start because of the negative?
JN = 74/78 or -4/0 or 48 20.70N 115 33.90W (Negative N/S is south, zero
E/W offset)
PT = 80/84 or 2/6 or 48 24.30N 115 37.50W (Now North of the start, and 6
puts us further WEST of the start?)
RN = 82/78 or 4/0 or 48 25.50N 115 33.90W (Still North of the start, but
zero E/W offset)
NH = Same as first
So, the N/S offsets are supposed to be E/W in-line with the object
itself (2nd and 4th points). Both images agree with that.
The first point is N/S in-line and EAST of the object...Yep, my debug
has the right value, but my plotting is worng. Copy/Paste error between
the debug and the actual point calculation!
The third point is supposed to be NW of the object, but mine is NE on
the plot even though my debug has the right coordinates. Funny how a
little +/- swap will do that to an image!

Re: [Xastir] Wx Alerts
Yes, I'm aware of the shapefiles for defining the geographical areas for NWS offices, but thanks for the reference. However, I'm trying to build an APRS client for the masses where a single download, a single configuration, and they're up and running. No other files to go fetch and/or keep updated against change. I'm striving for use of APRS-sourced data for the most part (Ok, I've deviated by fetching the EchoLink node status just before AVRS came online and I do support displaying geocaches from GPX files). The multi-line ovject format is much better, IMHO, than an external shapefile because the lat/lon data from the NWS's specific alert is encoded into APRS-speak and displayable from the single object transmission. Nice, precise, and not subject to a potentially obsolete set of shapefiles causing the alert area to be the wrong shape. Eventually, I might change my mind on this, but until I exhaust most of the APRS-sourced data, I'm trying not to branch out into other, especially non-ham, data sources. joking Besides, I have to leave some reason(s) for the existence of other APRS client software, don't I? /joking Lynn (D) - KJ4ERJ - Author of APRSISCE for Windows Mobile and Win32 Brian Webster wrote: Lynn, There are predefined codes that correspond to shape files which can be downloaded.

Re: [Xastir] Wx alerts
Yes, Curt, that would be fine. I did follow Tom, KM5VY's advice about the need for being hooked up with one of the APRS-IS servers. But, now, I need to wait for severe weather to test. Yes, documenting this would be most advantageous for us relatively new to xastir. I'll wait for you to initiate. 73 - Dale.

Some areas have Igates that transmit local WX alerts to RF, in which areas you would not need to be connected to the APRS-IS. You apparently do not live in such an area. The WX alerts are produced by NWS and fed into APRS-IS. Unless someone in your area is gating them, you have got to get them from the net. A lot of the detailed information about NWS alerts used to be documented on wxsvr.net, which site has gone down in the last year or so. In other words, in one concise place, are there docs that spell out (from start to finish) what has to be set up in xastir, what has to be working outside of xastir, etc to get the confounded Wx Alerts working?? If not, then what would be the best way of tracking this down so it's not so obscured? Even though you're not an IGate, you must be connected to one of the APRS-IS servers in order to receive the WX alert data. So you need to set up your Internet connection in Xastir, connect to one of the core servers or Firenet as originally suggested, and then you should see weather data. That is, add an internet server, such as rotate.aprs.net through the Interface-Interface Control-Add-Internet Server menu and use port 14580 with a filter of t/n. This will set your feed to give you only WX alerts. Modify your filter setting as needed, per http://www.aprs-is.net/javAPRSSrvr/javAPRSFilter.aspx to add additional data from APRS-IS that isn't making it to your local RF environment. Be aware that some filter options require that you transmit a position to APRS-IS before they'll feed you anything (e.g. m/200). In order to do that, you'd need to provide a passcode generated by the callpass program installed when you build Xastir. -- Tom RussoKM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236http://kevan.org/brain.cgi?DDTNM In some cultures what I do would be considered normal. -- Ineffective daily affirmation ___ Xastir mailing list Xastir@lists.xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
