    • RF Propagation Analytics
      The RF Propagation Analytics site demonstrates a practical application of analytics techniques. It lets you see what bands are open now (at least according to spots reported to the DX Cluster) and trends (both under the Activity button), can show maps of spot locations (both in flat Google map or Robinson projection), and lets you search for stations that have been reported or submitted reports (to DX Cluster).

      How It Works

      The server checks the DX Cluster every minute to see what new spots have been reported. It gets the latitude and longitude of each spot (if available in QRZ.com) plus the solar flux at the time (if lat-long is not in QRZ, the country is determined based on callsign and the lat-long of the capitol of the country is used). It saves the spots in a database. The database is then used for searching and mapping functions. DxDisplay is a service to demonstrate high speed analytics, provided by  The University of Alabama  Center for Advanced Public Safety, in conjunction with HamSCI. See the Documentation for results of various studies of the historical data in the database. <br style="color:#696969; font-size:13.600000381469727px; text-align:start">
      See also QRZ.COM article about the system: QRZ.com article  <br style="color:#696969; font-size:13.600000381469727px; text-align:start">

      WSPRNet data

      In May of 2017, an additional data collection function was added to collect a sample of WSPRNet data. The intent is to allow users to apply some of the same data visualization to WSPRNet data as done with the DX Cluster data, and also to allow data analysis that combines the two for increased analytics power. The data collector runs once per minute and collects 50 spots from WSPRNet (it is not intended to duplicate the entire WSPRNet database in dxdisplay). We think that 50 per minute will provide a statistically significant sample of WSPRNet data which can then be correlated with other data. You can view most of the displays with dxdisplay data and/or WSPRNet sampling included. We may change the sampling frequency once we see how well the "50 per minute" criterion works.


      In July, 2019, tracking of reported Winlink spots was added.

    • Ham Radio Science Citizen Investigation
      Since the beginning of the United States amateur radio service in 1912, amateur radio operators have made significant contributions to radio technology and the understanding of radio science.  This work must be continued today, as Part 97 of the FCC rules states that a primary purpose of the amateur radio service is the “Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art.”  Recent advances in the fields of computing, software defined radio, and signal processing provide unprecedented opportunities to meet this mandate, specifically in the field of radio science.  These opportunities are already beginning to be realized with the advent of systems such as the Reverse Beacon Network (RBN), the Weak Signal Propagation Reporting Network (WSPRNet), and PSKReporter.  In addition, enabling amateurs to make and contribute legitimate scientific observations will expose amateur radio to a wider community of people interested in science around the world.

    • Power failures
      I'm curious to know how any of you have dealt with power failures in past. Also, do you have obscure recommendations that you think others may not have thought of to deal with both short and extended failures?

    • Share your Net topic ideas
      Content-wise, there are basically two types of nets, nets without a topic, and nets with a topic. Nets without a topic have a place in our ham universe. They allow friends, or strangers, to just get on and share a story, the weather, a new purchase, or ask a question about some issue they might be having. Subject-driven nets are different, people arrive knowing what the day's subject matter will be. Please note that I am not talking about purpose-driven nets like traffic nets, weather nets, etc. I am talking about HF, VHF, UHF... nets, usually, but not always, run by clubs, to bring hams together.

      Which brings me to my ask. This would be a good thread to list ideas for subject matter. I will edit this top post to include the highlights of the suggestions given. I'll start the dance off by putting in some of my own ideas in the next post.

      C'mon ham community, let the pile up begin!!

    • Community Emergency Response Guide
      They don’t happen often or everywhere, but they do happen sometimes and somewhere. 

      In some cases they are predictable, and in others they are unthinkable. Tornadoes touch down, hurricanes make landfall, floodwaters rise, fires burn, utilities are interrupted, terrorists strike. 

      But with planning and preparation, you can make a difference. You can reduce a disaster’s impacts on you, your family, and your community. You can save lives, homes, and livelihoods. 

      The Fairfax County Office of Emergency Management is a resource for the community. Our mission is to make us all more ready for and resilient to all hazards. In a crisis, the government must focus on those in the greatest peril. The better prepared everyone else is, the better the outcomes are for all of us. 

      By reading this far, you’ve already taken the first step in preparing for the unexpected. Now it’s time to make a plan, build a kit, and help prepare your household and your community.

    • Is it time to rename the hobby?
      It used to be that an "Amateur" was someone who was not paid for something they did. The Olympics were Amateur Sports.  The best of the best but no one got paid to train and compete.  The definition of amateur was:"noun 1. a person who engages in a pursuit, especially a sport, on an unpaid rather than a professional basis."  Then somewhere along the line a second definition was added: "2. a person who is incompetent or inept at a particular activity."  this seems to be the more accepted definition.  

      Should we be renaming ourselves to "Volunteer Radio Operators" to shake that definition of incompetence from our hobbies name?
