Join Kaushik Kumar, KC1WNO, as he presents “AI and Modern Wireless Communication Systems” at the 2026 Northeast HamXposition. (Date, time, room T.B.A.)

This presentation provides a high-level introduction to artificial intelligence and its relevance to amateur radio and wireless communications. It focuses on building insight into emerging AI technology in ham radio through weak-signal decoding, interference detection, and propagation prediction for operators and enthusiasts.

I am a high school amateur radio operator and one of the youngest members actively engaged in regional ham radio communities, holding a General class license. My interest in wireless communications began in middle school and was shaped early through Arduino and Raspberry Pi projects, where I first explored embedded systems and wireless experimentation. I have since developed hands-on experience in RF systems through antenna setup, station configuration, and continued amateur radio operations. I currently serve as the Youth Outreach Lead for the Patriot Radio Club (Arizona), where I lead technical outreach efforts, support club activities, and mentor new and aspiring ham operators. I am also an active member of W1OP (Rhode Island), participating in disaster recovery events, winter field operations, and competitive RF communication exercises focused on real-world emergency communications. Beyond amateur radio, I have conducted independent research in AI-based assistive technology systems and developed a generalized zero-shot machine learning model for detecting zero-day attacks in low-power wireless networks, which was presented at IEEE conferences and the Massachusetts State Science & Engineering Fair. I continue to pursue amateur radio as a platform for technical outreach, integrating AI, embedded systems, and wireless communications while mentoring and inspiring new hams across New England and Arizona communities.

Join Corey Ruth, KD3CR, for “Stealthy All-Band HF from Attics” and Small Spaces” at the 2026 Northeast HamXposition.

“Living in an HOA, apartment, condo, or other restricted space, you know the struggle to put up decent antennas, especially for HF. Most options are complex, expensive, cover limited bands/bandwidth, have limited effectiveness, require tuners, or some combination. But theres another option. Its simple, cheap and easy to build, very flexible, and extremely broadbanded, covering all HF bands without a tuner: the Broadband Butterfly Terminated Dipole (BBTD). Learn about two versions of the BBTD: one that fits stealthily in a small backyard and another that can be completely hidden in an attic. Discover how these antennas work, how to build one for yourself, and how they perform on the air (spoiler: a lot better than youd think!).”

Corey Ruth, KD3CR, is the past president (2020-2025) of the Queen Annes Amateur Radio Club in Centreville, MD. Hes also a member of Queen Annes County RACES and Potomac Valley Radio Club. Living in an HOA-restricted townhouse, he has a keen interest in stealth antennas, believing that every ham, regardless of location, should be able to experience the joy of working the HF bands.

“All classes of licensees are welcome. However, we want to highlight the wide variety of activities in which Technician class licensees can become involved using their existing privileges.”

The series will be scheduled for Friday, and possibly be repeated on Sunday morning in a condensed format.

Join Jim Jones, KC1YGY, for a presentation of “Using AI to create software for ham radio” at the 2026 Northeast HamXposition.

Jim will discuss and show how he built his own hotspot software and logging software using AI.

Jim got into radio in high school when he met an Elmer through his church (N1AXS). “I found it fascinating to listen to radio stations from around the world. Even though it took me many years to get my license after that. I didn’t get my first license until I was in the Navy and helped with MARS. I used to be KG4UOF. In 2005, I moved to New Zealand, where I got the call ZL2USA. I was in AREC, the NZ version of ARES, and helped with many successful search-and-rescue operations. I also served as secretary of my local club for 2 years. I returned to the States in 2010 and had to put the hobby aside for a bit. In 2025, I received my general class license and writing software for ham radio operators.”

Join Rob Leiden, K1UI, as he presents “Organizing an RFI Team to help find and fix interference” at the 2026 Northeast HamXposition.

Getting RFI teams organized takes a combination of technical, personal and administrative skills. It’s hard work but it pays teams back in the gratitude of and recognition by hams who get help. The teams learn about the science behind RFI, work with the ARRL Lab to resolve tough cases and master troubleshooting techniques.

Rob, K1UI, is Assistant New England Director and an Assistant Section Manager in EMA. His interests also include promoting MESH networking to achieve a New England-wide network. Rob has been licensed for over 60 years and has held many club and ARRL section leadership positions. His on-the-air activities have included DX’ing, traffic handling and digital communications. Rob leads a team of about 50 hams in the New England Division working to help hams with their RFI problems. He also manages a groups,io reflector that brings hams from all over the country together to promote RFI problem solving and RFI team activities

Join Scott Halligan, KC1UA, as he presents “Successful Scanning in 2026” at this year’s Northeast HamXposition. (date, time, room T.B.A.)

“Lots has changed since we used to plug crystals into a scanner, or even punch frequencies in manually. As radio system technology has advanced, so have scanners! This discussion will show you what’s available in 2026, and what we are up against both technology-wise and encryption-wise, along with how Scanner Master determines the best approach to getting you scanning in your area.”

Scott began working for Scanner Master in April of 2023. Prior to that he was the communications supervisor for a Cape Cod police department for close to 34 years. Scott is also the founder of the Scan New England website and remains there in an active administrator capacity to this day. He has been an avid monitoring enthusiast since a lady that took care of him as a child shoved an old shortwave radio into his hands to keep him occupied. It was at the tender age of 7 when that moment occurred and he has not looked back since. He has been incredibly fortunate to combine a lifelong hobby into a career, starting as a Radioman in the US Coast Guard, installing C-Band satellite systems after his honorable discharge in 1985, and then the aforementioned police employment, starting as a dispatcher in 1988 and remaining one in addition to becoming the supervisor in 1996 up to his retirement in July of 2022. Scott enjoys a wide scope of the radio hobby to include searching for new frequencies and radio systems, DX’ing low band and tropospheric ducting band openings, listening to local public safety activity, and amateur radio (callsign KC1UA, licensed since 1990). He also enjoys traveling with his wife Linda, hiking, gardening, computing, billiards, and his sports teams to include the New England Patriots and Boston Bruins.

Join Terry Stader, KA8SCP, as he presents “Introduction to D-STAR” at the 2026 Northeast HamXposition.

This is an updated version of past HamX presentations, geared to both new and old time D-STAR users who may be missing some of the new adventures to be had. Not a D-STAR user? You, too, will benefit from this presentation to learn more about the mode. Q&A will be available!

Terry, KA8SCP, is a D-STAR system owner/admin for several MA/NH D-STAR repeaters. He also administers several REFxxx and XLXxxx multimode/multiprotocol reflectors.

Join David Olean, K1WHS, as he presents “VHF Auroral Propagation, What We Know” at the 2026 Northeast HamXposition. 

“A discussion of the requirements for successful Auroral communications on the amateur VHF frequencies such as 50 MHz thru 432 MHz. Some basics of the Earth’s magnetic field will be discussed, along with a few examples of actual contacts made and the geometry involved. Analyzing the propagation paths during Auroral storms is quite a challenge. A few actual contacts on VHF Aurora will be analyzed to provide clues as to how to best utilize auroral DX events.”

Dave Olean spent his career in radio communications, and has been a radio amateur since 1962. He was an officer in the US Army Signal Corps, and then worked for several antenna companies. Dave started his own antenna company in 1993, Directive Systems, manufacturing a line of VHF and UHF yagis, microwave dishes, and loop yagis. His interest in Auroral communications was kindled while working in a sounding rocket lab at the Univ. of New Hampshire in 1967. He fired off sounding rockets into the auroral curtains to measure magnetic fields and energetic particles. Dave has been happily scattering amateur VHF signals off the Aurora ever since.

Join Greg Algieri, WA1JXR, for a special Friday afternoon Introduction to “Impedance, SWR and Transmission Lines” at the 2026 Northeast HamXposition.

The presentation will introduce the amateur to what complex impedance is, how to measure it, how the Impedance is related to my SWR, how this all applies 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. Teacher for Long Island CW Club, ARRL WMA Assistant Section Manager and Technical Coordinator.
