The Nashoba Valley Amateur Radio Club‘s March meeting is Thursday, March 20th at 7:30 PM at the Pepperell Community Center (in Pepperell). We start gathering at 7 PM to socialize before the meeting starts. NVARC has a special treat in store for you at the March meeting.  Dale Clement, AF1T, will be talking about antennas.  NVARC has had Dale speak before, but we have enough new members and new hams that we just couldn’t pass up the opportunity to have him speak again.  Dale demonstrates practically and visually how and why antennas work.  Trust me: He’s entertaining, and you will learn a lot.  Do not miss this meeting!

The Board of Directors would also like to discuss possible plans for the N1MNX repeater system with membership, April elections of officers, Field Day in June, etc.  So please plan on attending the meeting.

If you need directions to the club meeting, please click <http://binged.it/smoogg> here and put your own address in box “A”.

Thanks, and 73. Please feel free to contact me if you have any questions.

March 18, 2025: “How to Become a POTA Hunter” by Harold Kramer, WJ1B.

Description: Parks on the Air, POTA, is one of the fastest growing and most popular programs in Amateur Radio today. This presentation will provide an overview of the Parks on the Air program and will emphasize the tools, techniques, and practices for becoming an effective POTA Hunter. Hunters are stations that are not operating in a park, but rather, usually at their home stations. Hunters are essential to the POTA program because without Hunters, the Activators, stations located in a park, would have no one to work!  

Bio: Harold retired eight years ago as the Chief Operating Officer of the ARRL and Publisher of QST. He still writes Product Reviews and Classic Radio columns. He is currently a volunteer at the ARRL Lab and a member of the ARRL Board’s Historical Committee. He is an avid POTA Hunter with over 2,600 confirmed parks.  Harold was first licensed as KN1ZCK at age 14. He spent his entire career in the cable television and broadcast industries. Before joining the ARRL, Harold was the Chief Technology Officer of Connecticut Public Broadcasting. He holds Bachelor’s and Master’s degrees from The University of Connecticut.  Here is a link to Harold’s website:  http://www.wj1b.com

Peter Morrison, AC1KY, will be speaking on “Aircraft Tracking with SDR” at the Wellesley ARS Meeting on March 18, 2025 at 7:30 PM at the Wellesley Police Station at 485 Washington St. (Route 16), Wellesley, MA. (Please park on the street, not in the police station parking lot.)

Aircraft Tracking using SDR will describe the ADS-B aircraft beaconing system, its development, and the use of low-cost RTL-SDR receivers to display aircraft data. Today, all aircraft worldwide are required to transmit ADSB signals.

The ADS-B (Automatic Dependent Surveillance Broadcast) is like radar in the sense that it also provides surveillance information to a controller. However, the way it works is a bit different, which will be explained later. An ADS-B system can
be further explained as below:

A (Automatic): The system requires no action from either the transmitter (aircraft/pilot) or the receiver (air traffic
controller)
D (Dependent): It is dependent on aircraft systems to provide the data
S (Surveillance): The information from the system is used to identify an aircraft
B (Broadcast): The data from the system is continuously transmitted by the transmitter or the aircraft to any station with
proper equipment to receive it.

The March PART meeting will be held on Tuesday, March 18, 2025, beginning at 7:30 PM at the Cameron Senior Center, 20 Pleasant Street, Westford, MA, and via Webex video conference.  For those attending via video conference, a meeting link is below; just click on the green button to join in.  You can join the conference any time after 7:00 PM to check out your gear or just rag chew until the meeting starts. Bear in mind that internet connectivity from the senior center may be unreliable.

 

Our guest speaker for the meeting is Tom Schiller, N6BT, who will be connecting via video conference from Arizona. Tom is the founder of Force-12 Antennas (now part of JK Antennas), and his topic is “Will it work?”, which describes looking at antenna design and components to see if the antenna will be efficient and, therefore, effective for us. There is a look at the construction and components of the fairly new Big Kansas Coil, plus other YouTube tests and two tests using our drones on a Buddi-Pole. There are also some suggestions along the way on magnetic loops.

 

All attendees are encouraged to bring donations of non-perishable food for the Westford Food Pantry.

 

See you Tuesday!

President, PART of Westford
