Some of our members recently purchased a solar powered, Arduino programmable, weather station kit from Karl, W4KRL at the Winterfest in Annandale, VA. Due to popularity of this kit, I invited Karl to come to our next club meeting to give a presentation all about it’s development, how the station works, etc. Karl has graciously accepted the invitation.
You may be surprised to learn that this is a new venture for Karl. For most of his career, as an electrical engineer, he designed large power electronics converters for rapid transit car propulsion systems. The Arduino project is the crossover between these two ventures. Planned areas of discussion include a presentation that focuses on the origin of the development of the kit, the challenge of designing a circuit board, and some of the unique technical issues involved with the design of this project.
Because of the content of this meeting, this should be of interest to not just the members of the HacDC Amateur Radio Club, but also to the general “Hackerspace”, “builder” and “maker” communities as well. All are invited and encouraged to attend.
As is the case with all of our events, there is no cost to attend. We look forward to seeing you at the meeting.
Grabbin’ the Tiger by the Tail…
Many thanks to Arthur Feller – W4ART, who led our first successful group build on the evening of March 22, 2017, of “Tiger Tails”, an antenna accessory to an HT transceiver that greatly improves transmit and receive performance.
This is the first of what are planned to be several “practical application” events. In these events, we will go beyond just learning about concepts and start to actually apply what we learn about a particular topic in a group setting in situations to enhance our skills as amateur radio operators.
The ARRL today published a story on their news page about the efforts of W3HAC members during the events of the Inauguration and the Women’s March on Washington. A link to the story can be found here:
On 12-31-16, several members of the HacDC ARC activated the highly sought after “Sewell-Belmont House” in Washington, DC to finish off the ARRL’s year long “National Parks on the Air” (NPOTA) initiative. This initiative was run in tandem with the Centennial celebration of the National Park Service. By encouraging use of amateur radio operations from and to these NPS facilities, the initiative helped promote the unique history of each park space and demonstrated the utility and diverse nature of the amateur radio service in these highly visible public settings. Thanks to all of those who attended and assisted in this and all of the club’s “NPOTA” activations throughout the year.
Hello friends of HacDC and HARC. We are finally launching our first high altitude balloon in several years with callsigns W3HAC-11 & W3HAC-12 on ARPS 144.390@500mW and 433.500@1W respectively at 9am. W3HAC-12’s frequency may change the day of due to conditions which we will announce. There should be a digipeater on W3HAC-12 for the duration of the flight which should be between 2-2.5 hours. Feel free to track us at http://aprs.fi/#!call=w3hac-11 or directly yourself. We are flying 3 cameras, 3 sets of sensor packages with data to be recovered after landing, and an SD card “resiliency” experiment.
We are launching from Strasburg, VA unless morning predictions cause us to go further south. The Spaceblimp team has been planning this since July so we hope you track us. Pictures, video, and data will be available a few days afterwards at http://wiki.hacdc.org/index.php/HacDC_Spaceblimp_6.
Please join HacDC in a National Parks on the Air (NPOTA) activation…with a twist!
Question: How do you activate the National Mall without stepping foot on the lawn?
Answer: By activating a unit maintained by the National Mall park!
You are invited to join the HacDC Amateur Radio Club (W3HAC) as we take amateur radio into the heart of the city! On October 15, 2016, following our club breakfast, we will attempt to activate the beautiful, but striking, African American Civil War Memorial at the intersections of 10th St., U St. and Vermont Ave. in N.W., Washington, DC (1925 Vermont Ave, N.W., Washington, DC 20001). We will be right near the top of the U Street/African-American Civil War Memorial/Cardozo Metro Station. Our approximate time of deployment will be between 1200-1300 EDT (1600-1700 UTC). We will have one station and band / modes for operation are expected to begin on 20M phone in the General portion of the band, with CW operation possible for all license classes to have an opportunity to work. Club members will self spot on popular sporting networks and encourage stations working us to continue to spot members as they QSY. Updates to FB will also be posted in kind for “W3HAC”.
By working our W3HAC station, you will help us demonstrate the amateur radio service to a wonderfully diverse mixed use residential/business community with a rich history in our Nation’s Capital. As a “Chaser” you will get credit for working park DZ06 / National Mall. As an “Activator” operator, you will get practice working in a field environment and enjoy an opportunity to make numerous contacts with your fellow operators from a wide variety of areas on multiple bands. You will also learn how the ARRL uses Logbook of the World to efficiently and effectively track and validate not only the contacts made, but the number of parks activated during this year long NPOTA initiative. You will be able to see first hand why this initiative has been incredibly successful in helping the National Park Service celebrate their 100 year anniversary while helping the American Amateur Radio Relay League educate and inform the public about the value of the amateur radio service.
Questions? Comments? Please just me know. My contact information follows the message.
Thanks and good luck!

Club member Jim Talens – N3JT was recently interviewed at his home station by the CBS Washington DC affiliate television station Channel 9 WUSA. He had the opportunity to discuss the history and continued use of Morse Code (CW) as a method of communications and why it is very useful in emergency situations. Click the link below:
