Re: Elecraft compatible WX station

How do you handle the internet connection? If I got something like
this, I'd be wanting to locate it at a station remote from my home and
to monitor it over the net. It looks like the Davis stations require
another piece (a Weatherbridge?) to make the link to the net.

I do not recommend Davis WX Stations. They are very RFI sensitive.
If anyone has succesfully modified one to eliminate RFI sensitivity I
would like to hear from you.

Re: Elecraft compatible WX station

In reply to this post by alsopb

Many years ago I talked with the professionals on the top of Mt
Washington, New Hampshire (record wind: 241 MPH and the
anemometer blew away). They say the the cup type anemometer
tends to act like a helicopter at about 100MPH and fly away.

They use pitot tubes to measure wind speed. This is the same
device as the one used to measure airspeed on an airplane. It
looks like a tapered tube with a hole in the end, usually
mounted on the leading edge of the wing on a light airplane. The
difference in pressure between the end of the tube and a
"static" source, unaffected by the wind, gives the speed.

A weather station using a pitot tube would be a good idea for
high wind environments.

I,ve had a Pest Bros. For a nr of years. Never any problems, even with my
Alpha. Never put the wind vane up!

Re: Elecraft compatible WX station

I've been wondering why there isn't an alternative to cup anemometers
for this application since the technology isn't that new.

google rc airplane pitot tube and you will come up with a large
practical knowledge base for building them. I build them in about 2006
with a Freescale MPX5100 sensor (might be better sensors available 7-8
years later). You still need a strong weather vane to keep the pitot
into the wind, but that's easier to make robust than a manic cup
anemometer at high speed.

Mine worked pretty good down to about 10-12 mph, but wasn't very
reliable below that. I gave it a couple of rides on the bike and it
worked to 130 mph and specs suggest it could go a lot higher. Anyway, if
it blows away in a hurricane, knowing the wind speed is probably the
least of your worries.

I've used the same type sensor to make a cylinder balancer for my BMW
R1100RT. In both cases, it was read with very simple software on an
Arduino. RC places sell complete kits for $25-50 so it would be easy to
experiment with. Make sure it is capable of stand alone operation.

Far off Elecraft topic, but it will be my only reflector post on the matter.

With my Davis Vantage Pro2 station I use Virtual Weather Station from
<http://www.ambientweather.com/software.html> which can put my weather
data on a Weather Underground Personal site that can be read on the
web. To see what it looks like you can see my data at:

Re: Elecraft compatible WX station

Thank you, Dave. The Weather Underground display looks like just what I
want, but I would like my remote station weather to transmit over the
net without a computer hooked up--thus perhaps the Weatherbridge
device...I wonder if folks have used this successfully.

As the original author of the query about WX stations, I would like to thank everyone who responded. I have decided on the Davis Vantage Pro wireless weather station.

I have had experience with these units before in my work environment and they performed very well. It's comforting to know many amateurs have had good experience with them in a RF environment.

Thanks again for everyone's advice. This thread can be closed now from my perspective.

Hey, Paul - if you're looking for a remote weather station that can be solar
powered and use strictly APRS; check out the Argent Data ADS-WS1
(www.argentdata.com)

I've developed 2 stations using these (KC7RAS-8 and N7QNM-10). KC7RAS-8 is
on top of the Columbia Center in Downtown Seattle and has "shore power",
N7QNM-10 is completely self-contained. They both transmit weather data
over APRS (2M packet on 144.39), that's viewable using www.aprs.fi or
anyone's APRS client.

It looks like maybe KC7RAS-8's anemometer is down, that's a pretty harsh
environment (76 stories up over downtown Seattle) and it's blown away is
66MPH+ gusts a couple of times. My station, N7QNM-10 is suffering from a
degraded solar panel or messed up charge controller; so the readings from it
may be a few days old as well (N7QNM-10 has been operational for close to 4
years).

Feel free to drop me a direct email if you have any other questions.
