Hi Wes,
The short answer is:
filter r/42/-94/287 t/n
This means:
range filter
range center: 42 N lat, 94 W lon
range 287 km (about 175 miles in this case)
type exception: n=pass all nws reports outside the filter
The doc you were referred to is very good...I just thought I'd give you a
quick and dirty answer.
....hasan, N0AN
p.s.
for Dayton I have done the following to monitor a few selected mobiles from
our area:
filter r/42/-94/287 t/n b/n0vpr-7/n0bkb-9/w0kwm-7/ki0bw-7
This passes my "buddies" outside the filter. You can also add area filters
with your range filter, but I have not tried it yet. (It would be a perfect
app to combine the short range filter with an area filter around Dayton.)
Anyone doing this?
Send example, please.

Yes, and the MR. Sid map images can be directly imported into Oziexplorer. I
purchased a 4 CD set of MrSid (all the North America) imagery downloaded
from thsi site from a poster to the Oziexplorer Yahoogroups mail list. Don't
remember his name, but could find out I suppose. Cool Stuff!

Yes, you can use multiple 'r/' range filters (up to 3).
filter r/42/-94/287 r/39/-84/250 plus anything else you want to include.
r/39/-84/250 is the Dayton area (250k around the Dayton center-point).

I am trying to remotely read battery voltage from a KPC3+ at one of my digi
sites.
Have read the Telemtry.txt file and have the resistors.
Questions:
1) If I enable the telemtry command will this send the Analog output to
beacon ?
2) Is adding the resistors neccesary for the KPC3+ to read correct voltage?
If so, exactly where should they be added?
Thanks
Jimmy

This would be an example of what you would see:

Sorry, that example was based on my own settings:
filter r/32/-114/805 t/mn r/39/-84/250
http://www.digitaldune.net/~ahubwest/sample.gif
805k around my own qth, all messages and NWS data, and 250k around Dayton

Definitely _not_ cool stuff! Warning: Angry map user rant below:
<soapbox>
Some state sites (and perhaps national) are paying to convert data to
MrSID format. U.S. taxpayers paid to have the data created in an
open, published format (like USGS DRG geoTIFF for instance), and then
paid again to have it converted into the less useful MrSID
proprietary format. Sure, Lizardtech makes available free viewers
for some platforms, but that's the only free method you can use to
view the MrSID files. The only other option is to use GIS software
which has paid a licensing fee to LizardTech in order to include
their decoding algorithm ($$). That knocks out all open-source
software and many low-end GIS/APRS programs.
Some states are paying to have this compression done in order to save
disk space on their download sites, converting the open formats to
the closed/proprietary format.
Some of the very cool things that you can do with topo maps in Xastir
for instance can't be done with some state's freely available data.
Only _some_ taxpayers who happen to live in the right states get free
access to the open formats. Others have only MrSID data files
available.
Anybody else see a problem here? Publically paid for data is
becoming less accessible, and we're paying to have it done! I
suspect the GIS people responsible for some of these state's data are
getting lured into this quite innocently because this nice MrSID
compression is already built in to most GIS software. I'm sure they
see the reduced file size as a win because they're not thinking in
terms of the accessibility of the data.
Yet another trend is to take USGS DRG geoTIFF files (topo map images)
and convert them to "Enhanced" DRG images, which in some cases means
cropping the white borders off, and in other cases cropping and
converting them to MrSID compression. In any case, they're not in
USGS geoTIFF format anymore, so again we've lost something that we
paid for.
With hard drives being relatively cheap, even for Unix servers, we
should all be suggesting to these state (and national?) sites that
the original image formats be kept instead of converting everything
to a proprietary format.
Oh yea, I forgot to mention: The MrSID algorithms were originally
developed by our government. How many ways are we getting screwed
here?
It looks like we might get MrSID read capability in Xastir soon by
the addition of yet another map library. That doesn't change the
fact that the U.S. taxpayers are losing something valuable by the
conversion of their map data into this proprietary format.
Open data is worth protecting isn't it? If not, we may not have much
of it in the future.
