Join Greg Algieri, WA1JXR, for an introduction to what complex Impedance is, how to measure it, and how Impedance is related to SWR. Greg will explain how these concepts apply to transmission lines, and how the waves and power travel from your transceiver to your antenna. 

WA1JXR began his Amateur Radio journey by asking his Dad for a Blue ‘Gillette Razor Blade’ to make his first diode receiver, which lead him to get his Amateur Radio license, higher electronics education, and an entire career with Raytheon, where he worked in radio and antenna design. Greg is active in the Amateur Radio community as a teacher for new and existing hams, restoring vintage radios, and getting on-the-air. He’s been a member of NEQRP since its beginnings, a teacher for Long Island CW Club, and is an ARRL WMA Assistant Section Manager and Technical Coordinator. 

Be sure to visit the HamSCI booth at the 2025 Northeast HamXposition and find out how the organization is helping to answer questions like: 

• How does the ionosphere respond to inputs from space and from the neutral atmosphere?
• How does the ionosphere couple with the neutral atmosphere and with space?
• What are the sources of medium and large scale traveling ionospheric disturbances?
• What are the causes of Sporadic E?

HamSCI, the Ham Radio Science Citizen Investigation, is a platform for the publicity and promotion of projects to advance scientific research and understanding through amateur radio activities.

Also, be sure to catch Dr. Nathaniel Frissell, W2NAF, our Saturday Grand Banquet speaker. Nathaniel will discuss the results from a number of recent HamSCI experiments, what’s next for HamSCI in the future, and how you can participate in these exciting projects!

Visit the W1 QSL Bureau booth in the vendor area and learn how the QSL Bureau works.  If you already have an account, you can check your status and add funds if needed.  You can open a new account if you do not already have one. 

We will be collecting Outgoing QSL Bureau cards to save you mailing them to the League.  Please follow the instructions on the ARRL web to prepare and fund your outgoing card package. 

At our booth we will also be checking cards for the ARRL DXCC and other ARRL awards.

The schedule is up and running.

As always, HamXposition, the New England Division ARRL Convention, continues to provide an exciting gathering with vendors and an ample supply of thoughts and ideas—also known as workshops, forums, and talks.

The schedule is now posted here on the HamXposition website at https://registration.hamxposition.org/Schedule/. It’s called “preliminary,” because we may add a few more reprise talks Friday and Sunday. The schedule will be off to the printer soon.

Here are the highlights:

• There’s a comedy kick-off on Thursday evening.
• There are five workshops, plus our mini Contest University and a club track on Friday. Plus, at least three fresh talks (which may be reprised later in the weekend) to attend if you’re not out at the flea market.
• Sixty-five talks, on Saturday, some of which will be reprised on Sunday if you miss them. Six talks, plus some reprises on Sunday. Saturday also includes Tech-in-a-Day and two sessions of license exams (with one more session on Sunday)
• A total of no less than 106 hours of talks are available over the whole weekend!
• All that, plus two banquets, gatherings of interest groups like contesting, youth activities, QRP, QCWA, and ARRL Sections. There will also be after-hours socializing.
• And prizes, prizes, prizes.

Join Douglas Sharafanowich, WA1SFH, for this fast paced, interactive session designed to provide a humorous insight as to what you can expect as a Net Control Station (NCS) during a fictional local Emergency/Disaster situation. This session is an excerpt of the full “Net Control Station (NCS) Operator Training Workshop” (3 hours). IF ABLE: Please read “The First 15 Minutes” presentation.

You can find it at https://tinyurl.com/yc5erdcm. Write down your observations and bring them with you. We will be focusing on: The Good, The Bad, and THE UGLY. 

Join Barbara Irby, KC1KGS, and Anne Manna, WB1ARU, as they host a “YL Meet and Greet” for YLs (“Young Ladies”) to socialize and discuss common issues. 

The use of thermal imaging for target detection and temperature measurement dates back to the early 1900’s. Currently the technology is affordable as the cameras are small, handheld and readily available.

Don’t miss “Thermal Imaging for the Radio Amateur” by Ronald Lucier, W1AAE, who will highlight the use of this technology as it applies to amateur radio: identifying and measuring hot spots on circuit boards, power supplies, connections and terminations. Additional subject matter regarding high power broadcast towers will be presented as will many practical applications. 

Ronald Lucier is a Mechanical Engineer with 40 plus years of experience in Thermal Imaging and the author of dozens of papers. He is currently the Chairman of ISO TC108/SC5/WG-11, “ Infrared Thermography”. He is recently retired from FLIR Systems having conducted over 1000 training courses. Ron was first licensed in 1972 as WN1PPX and currently is licensed as W1AAE. 

Join Matt Noyes and Danielle Noyes, co-founders of their digital-first weather company 1DegreeOutside and renowned former TV broadcast meteorologists, as they share their continued exciting journey pioneering a modernized approach to forecasting as a digital weather company.

In this engaging presentation, Matt and Danielle will discuss how their digital platform enhances weather reporting and public safety. They will also highlight their strategic partnership announced earlier this year with the WX1BOX Amateur Radio SKYWARN team and the indispensable contributions of Amateur Radio.

Come to the Maine Section Town Hall at the 2025 HamXposition, moderated by Maine ARRL Section Manager Phil Duggan, N1EP. Meet other Maine section members and catch up on ham happenings in the Pine Tree state!
