Special Event Presentation Planned for October 21, 2017

The HacDC Amateur Radio Club is planning for a very special presentation to be held on October 21, 2017 from 2:00 – 5:00 PM at Rock Creek Park in Washington, DC.  This event was originally scheduled for May, but was cancelled on the day of the event due to rain.  We are finalizing our official permit with the NPS at this time for the event, but anticipate no problems, since it is essentially a re-issuance of the initial request, which was approved.

Stuart Thomas / KB1HQS will be our very special guest.  During the 2016 ARRL National Parks on the Air initiative, Stuart earned top honors by racking up over 500 activations. He will be giving us a hands-on demonstration in the field of the types of equipment and antennas he utilized to help him achieve his first place status in the initiative. In addition to being an accomplished author and experienced outdoorsman, Stuart is a recognized expert in the area of mobile and portable amateur radio operations. He wrote the section on Portable and Mobile Operation in the “ARRL Operating Manual – 11th Edition”; articles for “QST” Magazine; and has a book in progress with the League on portable and mobile operations.

To find out more about Stuart, please go to his website: www.kb1hqs.com

After the demonstration station is set-up and the presentation is finished (approximately one hour), we will use the opportunity to activate the park under the World Wide Flora and Fauna Parks on the Air Program – Park Number KFF-0656, ending no later than 5:00 PM. In the event of RAIN, we will be forced to cancel, as the equipment he will be utilizing is not water resistant.

We will be meeting at Rock Creek Park, near the benches in picnic area 23 (black circle with the number “23” in the picture below), which is located just to the South side of the Tennis Center.

Keep in mind that there are several ways in which to gain access to the area, but the physical address to the tennis center itself is: 4850 Colorado Ave, N.W., Washington, DC 20011

This should be a GREAT TIME! Lots to see, learn and do. ALL ARE ENCOURAGED TO COME AND PARTICIPATE.

Even if you don’t have an amateur radio license, there will be licensed amateur operators available to help you make your first contacts on the air!!!

Like all of our amateur radio meetings, this event is FREE TO ATTEND!

Please note:  If you plan to bring your own food or beverages, glass containers and balloons are not permitted in the park.  Also, nothing may be staked into the ground nor attached to any natural or man-made structure (for example, you may not attach hammocks to trees, erect tent covers that use poles that stake into the ground, use lawn umbrellas that stake into the ground, etc.).  If you have any questions about the event, please call me.  My contact information is listed below.

Thanks. We hope to see you there!

HacDC ARC Again in Partnership with the National Park Service Through Use of Amateur Radio – International Lighthouse and Lightship Weekend / August 19-20, 2017

HacDC ARC Again in Partnership with the National Park Service Through Use of Amateur Radio – International Lighthouse and Lightship Weekend / August 19-20, 2017

The HacDC ARC is very pleased and honored to announce that we will again be in partnership with the National Park Service through use of amateur radio technology at a public service event. The George Washington Memorial Parkway Section of the NPS will be coordinating with our club to celebrate, “International Lighthouse and Lightship Weekend” (ILLW) at the Jones Point Lighthouse (ILLW# US0167), Jones Point Park, located at 100 Jones Pt., Alexandria, VA 22314 throughout the weekend of August 19-20, 2017 (see more below about times). This event will help the NPS and the community come together to celebrate the rich history of this resource.

From the NPS, “The Jones Point Lighthouse is one of the last riverine lighthouses in the country and the only one still standing in the Chesapeake Bay area. Today it is the focal point of Jones Point Park and a clue to area’s history as a busy commercial center and naval base.”


Having started in 1993, the ILLW initiative is part of a world-wide campaign to educate the public about the history and importance of lighthouses and lightships. This is done through the use of amateur radio activity as a highly visible, publicly accessible way to promote this message at these locations. Additional information can be found online at:


While the initiative will run for a continuous 48 hour period starting on August 18, 2017 at 8:00pm local time (August 19 / 0000 HRS UTC), due to park hour limitations and staffing restrictions, it is not yet clear the entirety of the exact times of operation that the club will be “on the air”. We will try to maximize our effort, however, and we hope, at a minimum, to have a full public event available on both Saturday the 19th and Sunday the 20th, from 10:00 am – 4:00 pm local time (1400-2000 HTS UTC).

We are going to set up a working HF station and “activate” the park under the World Wide Flora and Fauna Parks on the Air Program (WWFF), unit number KFF-0670 (George Washington Memorial Parkway) on the web:


and make contacts on various bands / modes / as conditions, operator availability and interest dictate. We will be trying to get as many “guest operators” on the air as possible to generate interest in the hobby.

To commemorate this special occasion, the club has applied for the use of call sign “N3P”. We will be utilizing either that or the club’s call sign “W3HAC” in making our contacts.

We will also have a special QSL card available. Instructions to obtain the card will be posted on the club’s QRZ page under call sign “W3HAC” at:


We will post updates on spotting clusters and on Facebook groups for the WWFF Program if mobile coverage is available.

The National Park Service is currently in the process of developing promotional materials for the event and is anticipated to update their website for the park accordingly.


We look forward to either meeting you at the event or hearing you on the bands!

Scheduled Presentation for June 14, 2017 / 7:30 PM: Software Defined Radio and the DARPA Hackfest


The HacDC Amateur Radio Club is honored to have one of the former lead developers of the GNU Radio project in to speak with us about the exciting field of Software Defined Radio and the upcoming DARPA Bay Area Hackfest!

Our guest speaker, Dr. Tom Rondeau, writes: 

The DARPA Bay Area Hackfest, in partnership with NASA Ames, is all about exploring the electromagnetic spectrum in new and interesting ways that are likely to become consequential in both civilian and national security contexts. Toward that end, my team is putting a software radio onto a remotely piloted aircraft, a UAV, and we will make this model system available at the Hackfest to innovators in the community who we hope will develop exciting new opportunities to build better and more complex cyber-physical systems. 
The Hackfest, which is open to anyone, comprises three parts: a speaker series, a hacker space, and the Hackfest Missions. The speaker series and hacker space run throughout the week as open sessions for anyone to come to and interact with experts and enthusiasts in software radio and UAVs. In the Missions portion of he Hackfest, we are asking participating teams to solve specific technology goals based around the software radio-enabled UAV. Those wishing to participate in the Missions portion, however, must apply to do so. In this talk, I will describe the Hackfest in detail and specify how to participate in the Missions. 
By opening new ways for programming wireless systems, whether they are UAVs or internet-connected household appliances, software radio can provide the foundation for many future capabilities. This Hackfest provides an opportunity to make a big step in that exciting direction.

You can read about Dr. Rondeau’s experience in giving this presentation to the “Fat Cat Fab Lab” Makerspace in New York City, NY by going to:
