I'm running 4.5 on OpenSuSE-11.1 here. Xastir has a run-time check to make sure that the version it was compiled with and the version it gets linked/run with are the same, else it disables map caching. This is required to prevent Xastir from crashing due to a mismatch.

I think FreeBSD installs the headers for each version in different directories so, theoretically, you can have multiple versions installed and compiled against without interference, you just have to manually specify where the headers and libraries are. My system has 4.1 and 4.3 installed and it seems to work ok. Great, except that there's little control in the linker for what you get linked against. Berkeley DB library tends to like to crash if you compiled for one API and then change to a newer version of the library at link time that has a different API. If you have a method to control what library Xastir will link against when you run it, then you should be safe. Because I didn't have (or didn't know of) such a method with Linux, I added the run-time code to disable use of the BDB library if this problem is detected, saving Xastir from a nasty crash. -- Curt, WE7U. http://www.eskimo.com/~archer APRS: Where it's at!http://www.xastir.org Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.

Hi Curt; Yes, I have entered them in the dialog correctly. And yes, I have a working internet connection. I've read the wiki and other documents regarding internet interfaces, and I've searched through the mail archives. I'll check the FAQ for the config file thing you mentioned. The message says it errors on opening the interface. That's why I am wondering if it's a permissions thing; but I don't know where to look or specifically which interface it's trying to open.

Re: [Xastir] More on radar problem
I haven't had a problem using radar directly from NWS. I generate GEO files for the RIDGE image for specific areas. It won't give you all of CONUS unless you pull in every RIDGE file but it works for zoomed areas. NWS has a page about it here: http://www.srh.noaa.gov/jetstream/doppler/ridge_download.htm They also have the following GIS page: http://radar.weather.gov/GIS.html Which contains a link to a location where you can download the regional CONUS GIFs. When you go to the National/Regional Mosaic section and get the file list of GIFs, look for the named files as mentioned (e.g. southeast, southwest, etc.) which will give you one of the eight regional mosaics. Once the GEO file is set up, either of these work quite well in Xastir.

I know next to nothing about geo files. Jim WA9ARB The easiest way is to follow along with one of the default GEO files and make the appropriate modifications. Here's an example of my GEO for the Atlanta area RIDGE radar (watch out for word wraps): # X Y LongLat URL http://www.srh.noaa.gov/ridge/RadarImg/N0R/FFC_N0R_0.gif TIEPOINT0 0 -87.37500 35.58083 TIEPOINT620 620 -82.00217 31.14133 IMAGESIZE 620 620 REFRESH 60 TRANSPARENT 0x0 PROJECTION LatLon The TIEPOINT directives will assign a specific pixel coordinate (X,Y) to a specific lat/long. Pixel 0,0 is upper left, and 620x620 is the lower right most pixel on my RIDGE image (the image itself is also 620x620 in this case). You need two TIEPOINTs so that Xastir can appropriately place the image. The IMAGESIZE tells Xastir how big the radar file is in pixels (again 620x620 for the Atlanta RIDGE). After that, just fix the URL accordingly. The more accurate the points, the better the radar will line up with your maps. I used Delorme Street Atlas to find a couple known points in the RIDGE data and then worked my way back to the corners. You don't have to use the corners of the image file, any two points will do since Xastir knows about the overall image size using the IMAGESIZE directive. You may have to play around with the TRANSPARENT directive which tells Xastir what color is defined to be transparent for overlay purposes. ___ Xastir mailing list Xastir@lists.xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir

That's only if you are both using a filtered interface where the filtering depends on your location -and- you started the interface after starting Xastir. If you had waited 30 minutes it would have automatically started coming in (your 2nd transmit after starting Xastir). If you had shut down Xastir and restarted, with that interface set to automatically start, that would have worked as well.

Re: [Xastir] More on radar problem
I'll find the explicit reference (all I can find is the full-US mosaic right now) but using Delorme is a real poor hack since the projections are different between RIDGE and Street Atlas.

Re: [Xastir] More on radar problem
It's a poor hack but it works enough if I can find accurate markers (like junctions in highways) since those should have identical coordinates no matter what software is being used. I only need anchor points, not much else. --- On Sun, 12/6/09, Gerry Creager gerry.crea...@tamu.edu wrote: From: Gerry Creager gerry.crea...@tamu.edu Subject: Re: [Xastir] More on radar problem To: Xastir - APRS client software discussion xastir@lists.xastir.org Date: Sunday, December 6, 2009, 11:40 PM I'll find the explicit reference (all I can find is the full-US mosaic right now) but using Delorme is a real poor hack since the projections are different between RIDGE and Street Atlas.

Re: [Xastir] More on radar problem
Thanks a lot for this technique Alex. I've gotten some weather radar on my
Xastir maps now.

The more accurate the points, the better the radar will line up with your

data and then worked my way back to the corners. You don't have to use the
corners of the image file, any two points will do since Xastir knows about
the overall image size using the IMAGESIZE directive.
Note that if you get the same file with a .gfw extension, you'll get some
information on the radar map that is returned. This includes the coordinates
for the upper left corner (0,0) and the number of map units per pixel. If you
take these statistics, and multiply them by the resolution of the map
(600x550), you can calculate the lower right corner of the map. So, for
example, for the NYC map (OKX),
http://radar.weather.gov/ridge/RadarImg/N0R/OKX_N0R_0.gfw will return:
0.00951144131747161

-0.00951144131747161

I wrote a perl script that will take as a single argument the abbreviation of
the radar station off of the NWS site, and output to STDOUT a .geo file that
should be correct for it. Note that you'll need to install LWP::UserAgent and
Image::Size off of CPAN to make it work. Hopefully folks find this useful. If
someone wants to brush it up and put it into contrib or something, they have my

Re: [Xastir] More on radar problem
I'll apologize now for not being able to keep my site up and operational. Little problem with sys admins, hardware failure and the fact that NWS gets paid to do this, and I'm still trying to get funding outta them to support some of the things I do that NWS benefits from. OK so I've whined. Fact is, my site's been down hard with a couple of large RAID failures, and a pair of dual-drive RAID failures on individual machines. Mark this down: RAID is no substitute for backup. And if your backups aren't happening, then you are in trouble. I'm recovering the TAMU site, as best I can, now. First things first: I've gotta get my weather models going. I've got to get the Texas Mesonet page displaying at least real-time data again. Then I can get radar back up. I've been able to pretty well keep the Level II and Level III data caches for NWS and NCEP up but the processed stuff lost out when I lost the disks on that processing system. Losing all of the Mesonet disks was another big hit. Gerry Alex Carver wrote: I haven't had a problem using radar directly from NWS. I generate GEO files for the RIDGE image for specific areas. It won't give you all of CONUS unless you pull in every RIDGE file but it works for zoomed areas. NWS has a page about it here: http://www.srh.noaa.gov/jetstream/doppler/ridge_download.htm They also have the following GIS page: http://radar.weather.gov/GIS.html Which contains a link to a location where you can download the regional CONUS GIFs. When you go to the National/Regional Mosaic section and get the file list of GIFs, look for the named files as mentioned (e.g. southeast, southwest, etc.) which will give you one of the eight regional mosaics. Once the GEO file is set up, either of these work quite well in Xastir. I use the RIDGE when I'm zoomed in and the regional mosaics when I'm zoomed out. --- On Sun, 12/6/09, Tom Russo ru...@bogodyn.org wrote: From: Tom Russo ru...@bogodyn.org Subject: Re: [Xastir] More on radar problem To: Xastir - APRS client software discussion xastir@lists.xastir.org Date: Sunday, December 6, 2009, 8:38 PM On Sun, Dec 06, 2009 at 07:35:18PM -0600, we recorded a bogon-computron collision of the jjo...@itol.com flavor, containing: Gents, I tried manually going to Tamu web site and trying the various urls listed in the various geo files...all I ever get is object not found.

Oddly, this is converted to an image by imagemagick (using html2ps), which leads to a blob of random junk in one corner of the display on my systems.
