Weather at the Ranch

Melissa, TX

The links in the menu take you to displays of the current and historical weather at my QTH. Weather data was originally supplied by my Heathkit ID-5001 Advanced Weather Computer (yes, I really did build it from a kit!). In 2008, I started using a La Cross WX-2315 weather station. In 2009, I switched to the current station, a Davis Vantage Vue. I have a WeatherLink USB datalogger installed in the main display unit (I have 2). I was using the WeatherLink software to access the station and then I accessed the WeatherLink tables to update my databases. However, an anomoly in the datalogger would cause the WeatherLink software to get stuck every couple of days when the datalogger would come across certain pages with invalid future entries (probably due to nonvolatile RAM being damaged over time). As of 2/2014, I wrote my own Java application to read the datalogger, throw away the bad entries, and update the SQL database. The Vantage Reader Java application is available if you email me directly. The app reads the Vanatage Vue, updates a SQL database (any with JDBC support) and produces a wxnow.txt file for APRS. My weather is fed to the CWOP (NWS citizens weather program) via my Amateur Radio APRS station (AE5PL).

The Java reader software (VantageReader) and the Java IGate (javAPRSSrvr) are currently running on a RaspberryPi (a small, experimental ARM processor board with 2 USB ports and a Ethernet port) running Raspbian Linux. The entire station (weather & APRS) can survive extended (greater than 5 hours) power outages and the VantageReader software will update the server's SQL database when it comes back online.

I have recently moved the Java applications to a RPi 2B and added Pi-Star with a ZUMSpot radio/modem for D-STAR.  A full description of this setup is found elsewhere on this site .
