Join Larry Banks, W1DYJ, at his 2025 HamX talk where he will share the results of modeling his stack of home brewed 5-element 10m Yagi, 20m Moxon, and 15m dipole.
“Recently with the improving sunspot cycle, he reports, “now and then heard something I don’t understand. Recent modeling revealed counterintuitive antenna patterns.”
HamClock is a ham radio application that integrates propagation forecasts, solar weather, DX spots, DX information, and terrestrial weather into one kiosk-style view that can greatly assist in DX hunting.
George Allison, K1IG, will demonstrate the program and show how to install it on your computer, as well as how to use a Raspberry Pi to display it in your shack.
George served almost 30 years in the U.S. Navy, finishing up as head of the Navy’s Computer and Telecommunications Command.
RF PCB design is often considered one of the more challenging aspects of electronics engineering due to the high frequencies involved and the sensitivity of signal integrity. In this presentation, Max Kendall, WØMXX, will dive into the core principles that underpin effective and reliable RF board design. He will explore the importance of using a 4-layer PCB stackup, which allows for better isolation, dedicated ground and power planes, and improved signal performance.
Topics will include the role of copper pours in managing return paths and minimizing interference, as well as how to achieve proper impedance matching for critical RF components and transmission lines. Max will also walk through best practices for feedline routing, highlighting techniques for minimizing signal loss, avoiding crosstalk, and ensuring consistent characteristic impedance throughout the board.
The Amateur Radio Emergency Data Network (AREDN) is a system leveraging modified commercial off-the-shelf (COTS) hardware to establish high-speed, self-configuring, and self-healing data networks in amateur bands. AREDN has the capability to deliver critical and redundant Internet Protocol based infrastructure that is independent of traditional Internet infrastructure.
Join this HamXposition presentation by Ben Jackson, N1WBV, as he discusses the basics of AREDN, what you can do with it, the status of projects in the New England Area, and how you can contribute by setting up your own node.
Andy Stewart, KB1OIQ, has created a ham radio software collection called “Andy’s Ham Radio Linux.” This freely downloadable software has over 100,000 downloads to date. It now runs on several flavors of Linux including Raspberry Pi.
Andy’s talk will be a high level discussion of some of the available software. You won’t want to miss it!
Join the Club Track on Friday afternoon. Affiliated Club Coordinator Bruce Blain, K1BG, will host this track featuring representatives from successful clubs sharing ideas and programs that will help clubs energize, invigorate, and grow.
Handwritten logs aren’t a thing of the past! Some of our fellow amateur operators, such as those with vision impediments, still record their contest logs on paper but many contests now require digital Cabrillo logs.
John Pooley, W1JPI, will discuss the applicability and merits of Artificial Intelligence including Optical Character Recognition and newer technologies like Generative AI for multiple topics within the Amateur Radio hobby with a focus on log transcription.
Join Kenneth Carr, KE1RI, as he will present on the New England Wireless & Steam Museum, located in East Greenwich, Rhode Island.
Ken writes, “We will bring with us a larger number of very early amateur and consumer radios and related equipment.”
Join Hisen Zhang, KD2TAI, for his talk entitled, “De-mystifying Quantum Computing: Application of RF Control System,” one of the many outstanding technical talks that will be presented at the 2025 Northeast HamXposition in Marlborough, MA, August 21-24, 2025.
Find out about the Courage Kenny Handiham Program, who they serve, and the many volunteer opportunities. The Handiham Program turns 58 this year, and Program Coordinator Lucinda Moody, AB8WF, has lots of stories to share from over the years along with plans for the program’s future at the 2025 Northeast HamXposition!
