The 2025 HamXposition QRP Build-A-Thon kit will be the “Cento Receivo”, a 40m direct conversion receiver kit! Another feature of this kit is that there is very little soldering involved in building this kit. All the components simply plug into SIP (single in-line pin) sockets….which allows for a quick build with a minimal set of tools.

The NEQRP sponsored Build-A-Thon is on Saturday at 7PM in the Marlborough Room W-9 and is opened for ANY and ALL Attendees of the Convention, young or old..

We recommend purchase the kit in advance: (There will be a ‘small number’ of kits at the Build-A-Thon for purchase if needed. … Why purchase the Build-A-Thon kit in advance? … So we can supply ALL participants a kit at 7PM on Saturday the 23rd. Again, ALL are Welcome to participate in the NEQRP Sponsored Build-A-Thon.

Purchase a kit at:

Again ALL interested parties, young and/or old builders, are invited to take-part in our Annual Build-A-Thon, starting at 7PM on Saturday, August 23rd, at the end of the West Wing hallway (Marlborough Room W-9). Kids or old-timers are welcome. It’s a FUN, EXCITING, and, LEARNING, Convention Activity/Event.

Many new hams and retiring hams are living in apartments or condos where they have limited ability to get on HF while others have constraints like HOAs or family concerns about the aesthetics of wires, masts or beams hanging on the house. It takes more than reading an ad or buying a mobile antenna to get on HF. First, they must understand the basics of antennas or they are stymied. This presentation by Robert Glorioso, W1IS, covers the principles and discusses examples of successful HF antennas in restricted environments.

Co-Authors Bob Glorioso, W1IS, and Bob Rose, KC1DSQ, have written two QST Cover Plaque articles since June 2021 and the 2024 Antenna Design Competition for their All Band 160m OCF in August 2025. They wrote several articles for CQ including as Guest Antenna Editors. They just released the Second Edition of their book on wire antennas available at OCFmasters.com. W1IS and KC1DSQ are retired engineers who have been working for the last seven years on antennas of all sizes and shapes, single band beams including phased dipoles and multi-band configurations, with a goal of delivering less than 3:1 SWR across a wide range of frequencies. 

Join Max Kendall, WØMXX, and learn how high altitude balloon programs can be used to inspire and engage youth to push themselves to new heights. As Amateur Radio operators, high altitude balloons offer us a low cost near-space platform for exciting engineering and radio projects. Learn from the New England Weather Balloon Society’s successes and failures and see what some of the work students are doing in the StratoScience Lab program this year.  [See HamX program schedule for date and time.]

When Hurricane Helene tore through western North Carolina in the fall of 2024, the damage was swift, unexpected, and widespread. In this photo-rich presentation, Thomas Witherspoon, K4SWL, will share his firsthand account of the storm’s aftermath and how amateur radio played a crucial role in staying connected when everything else failed. He will also offer practical advice for operators—no matter where they live—on how to prepare for natural disasters, build resilient communication setups, and foster stronger local networks. Even if you think you’re “out of harm’s way,” consider this your wake-up call to be ready. 

Thomas Witherspoon, K4SWL, has been a ham radio operator since 1997, making most of his contacts in the field with low-power (QRP) gear. He runs QRPer.com, the SWLing Post, and the Shortwave Radio Audio Archive, and is a regular co-hosts the Ham Radio Workbench podcast. A 2023 inductee into the QRP Hall of Fame, Thomas has a deep love for chasing weak signals from the great outdoors. 

Digital signals sound just like noise in our narrowband receivers. You may not realize that some of the noise you hear is caused by DTV and other digital transmitters. Join Paul Wade, W1GHZ, who will help you identify this insidious noise raising your noise floor and reducing your receiver sensitivity, and what you can do about it.

Paul Wade W1GHZ, previously N1BWT and WA2ZZF, has been licensed since 1962 . He has been a microwave experimenter for years and published numerous articles as well as writing the “Microwavelengths” column in QST. He was past President of the North East Weak Signal Group (NEWS). An ongoing project is the “W1GHZ Microwave Antenna Book” – online at www.w1ghz.org.

In 1997, he was honored to be named by the Central States VHF Society as the recipient of the Chambers Award. He has been honored by the ARRL with the 2000 Microwave Development Award, in 2001 with the Thomas Kirby Eastern VHF/UHF Society Award, and in 2009 by Microwave Update and the North Texas Microwave Society with the Don Hilliard Award for Technical Contributions to the Microwave Community. In 2025, he was honored to receive the ARRL Doug DeMaw, W1FB, Technical Excellence Award. Paul is a Life Member of the IEEE.

After a long career in electrical engineering, including microwaves, computer hardware, and signal integrity, he and Beth, N1SAI, are now happily retired in Vermont with a rescue dog named Daisy. He was also a ski instructor for a time, and now enjoys skiing on a new bionic knee, and skijoring with Daisy. 

The New England QRP Club has announced its full schedule of events and activities at the 2025 Northeast HamXposition on August 22-24, 2025. In addition to meals, a vendor night, and W1B talk-in station, NEQRP will host a Saturday afternoon seminar of talks and presentations.

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!
