The latest news item here,
http://www.wxqa.com/news.html
and the "more information" link shows how APRSWXNET/CWOP weather data are
being used to help fight wildfires.

What APRS clients support telemetry messages? Which ones perform the
coefficient calculations and use the unit labels?

I have an old Peet Bros. Ultimeter II (not 2K), that I hook up to my
APRS station. I have never been sure that I am getting "good" readings
because I have been unable to get it positioned satisfactorily. I have
seen that the WX service has a large ventilated white box for some of
their instrumentation. New temperature sensors from Lacrosse and other
companies look like they are enclosed in a ventilated plastic cup. Has
anyone built an enclosure for their sensor that keeps the wind, rain,
and direct sun from impacting the sensor and making it give a false
reading.

I sure like the new photo maps on findu, but don't recognize the
territory around a number of callsigns I have look up. Is the glitch
known already?

There are a lot of designs out on the internet for that. Do a google search
on weather stations and get to some of the home stuff and web sites, usually
if you find one or two of those with links you will find some links to the
different models.
As an example I have used a AC Garden Light for my solar shield from home
depot. Buy 2 of them about $7ea cut the standoff's to 1/2 size and put some
more of the rings in the stack from the 2nd one. Discard the glass jar (for
the light bulb) and the top/bottom of the 2nd "light pagoda" and assemble
with the temp sensor inside of it. Cover the inside with window mesh instead
of the glass jar and use a PVC threaded socket to mount it to a pipe of some
sort while routing the cable and slack inside of the pipe.
Easy as pie, just difficult to explain. Just go to the electrical department
at Home Depot and look at the 120v garden/walkway lights and you will
instantly know what many of us are doing.

I got this idea from Mike KB4TOH...
I took three white Styrofoam cups stuck inside each other and mounted the
temperature sensor inside where it does not touch the inside of the cup. I
tie-strapped the cups and sensor to the side of my tower. The Warning
Coordinator from the Newport NWS "approved" the install with a laugh... It
works well and survived Hurricane Isabel with no problem. And, hey, if they
break your out fifty cents.
