Karl Berger / W4KRL giving his presentation about his Internet of Things Weather Station during the April 17, 2017 OVH Meeting. Karl’s slides are here WeatherStation_w4krl for your reading pleasure. Additional information about the Weather Station project, including how to purchase a low cost kit of parts for it are available at http://w4krl.com. Karl’s weather station project uses the “free” online Matlab based and provided analytics through the http://thingspeak.com web site – which is worth exploring to find out what facilities are available there and what can be done there for very low cost. His project also uses http://aprs.fi web site.
VP’s Corner Jeff Fuller WB6UJE One of the more interesting things I’ve seen during my return journey to ham radio has been the marriage of the microprocessor and the radio. It started with frequency synthesizers. Easy to net everybody up on one frequency and no more drifting VFOs. And them came digital modes. All those nifty error correcting codes I studied years ago in school were once limited to pencil and paper exercises, or maybe a mainframe lab or two. Now they run on a laptop computer sound card, like the one I used last month in a transatlantic QSO running five watts of PSK31. And, ham radio has joined the Internet of Things (IoT) – a variety of unmanned systems and sensors for monitoring and reporting. Want to learn more about IoT ?

PRESIDENT’S LETTER: Well it appears that spring has finally sprung. The season started off with the first Mini-Tri of the year, and the turnout was good. Thank you to all of the volunteers and to Andy (KJ4MTP) for the planning. Our next event is the 2017 Manassas Air Show on Saturday, May 6th (rain-out day: May 7th). This will be our second appearance as an exhibitor at the Manassas Regional Airport. If the air show this year is anything like in past years, it will have about 20,000 visitors and should offer a fun time for the whole family to take in the aerobatic performances, aircraft displays, and the numerous informational booths of various Manassas organizations. Even though it is still in the planning stage, we expect the OVH booth to have HAM radio equipment on display, working ham radio(s), and possibly some demonstrations of HF radio SSB and PSK31 operation, handouts about… Read more »
