Presentation - Weather Station
Good evening everyone, I am Fred WK1F, and tonight I will be talking about our
weather station. I am co-owner of weather station WK1F-2, and Patti WK1E is
the other co-owner, not so much in the operation side, but money support and
on-site maintenance support which is outstanding.
This weather station has been on the air very successful for over 19 years and is
located in Yulee, Fl. Most down time can be contributed to lightning damage plus
loss of power. I am constantly studying ways to make it more sustainable for checks
and accuracy and making changes as possible. Presently we have a total house
standby generator. The 2000VA UPS supply will keep the complete weather
system functioning for about 6-hours and I have plans to increase this time by
installing additional batteries with 2000WH capacity.
This station utilizes WinAPRS 2.9.0 and sends weather information via the Internet.
Plus, transits over 144.39 simplex. Normally, the 2-meter transmissions are
redundant, but it is an important link for local use and when the Internet is down. All
weather sensors are located on our 75-foot tower, located about 125 feet from the
house, with the anemometer at the top and other sensors about 15 feet up from the
ground. I have remote capabilities via the Internet to monitor and change the
operations where ever we roam.
Why do we have a weather station?? Mainly, because I wanted to see the
constant live changes at my location. My first weather data interest was due to my
many weeks of being aboard various ships in the Pacific and Atlantic on ocean
stations while serving in the USCG. A fellow ham, Temp W4HZV, now silent key,
suggested that I put a weather station together - so it has evolved to a full blown
system over the years. Temp retired from NOAA as a field technician that worked
around the world for installations and repairs. Enough about me, lets talk about a
Our station is made by Peet Brothers and that is what I will be talking about tonight,
this company is well know for their USA made products. There are other weather
stations available, some good, some bad, some unable to get on the air or Internet
Some of my reasons for a Peet Bros weather system:
1: All wired, no batteries. System has been successfully tested at 325 feet between
sensors and keyboard.
2: Peet Brothers designed their products to be compatible with Amateur Radio.
3: Knowledgeable people answers the phone.
4: All terminal connection drawings, pin-outs and "how to test" readably available.
5. Parts normally are readily available and they keep records for warranty concerns.
6. If you have a problem, they want to help and will not stop until you are satisfied.
What does this system do for me, community and learning institutions?
With appropriate licenses and having your signal on the Internet, the data is shared
world wide. Learning institutions collect data constantly. Local National Weather
Service (NOAA) could care less about day-to-day data as they use their systems -
HOWEVER - when an incident is happening they need this local information.
However, NOAA does use our data, see: https://madis.noaa.gov/. Weather
Underground uses our data regularly. For me, it is the availability of instant and past
Explain the weather station in detail.
1: PK232 TNC's are old but still upgrade able. Problems with heat and low voltage.
Temperatures above 80F and/or DC voltages below 13VDC it becomes very
2: You can save some $$ by getting a MFJ1270X TNC but must use APRS system
in the "Kiss Mode" only. Note: MFJ does not make this, only resell.
3: Various APRS systems are now available besides WinAPRS and are free. To
name a couple: YAAC; APRSISCE, and UI-View. UI-VIEW is without any updates.
4: If you are interested in a weather station, seek out "APRSWXNET/CWOP for lots
of information. My ID is "AP505".
