Join John Facella, K9FJ, for an introduction to the Quarter Century Wireless Association and to meet and greet other QCWA members at the 2025 Northeast HamXposition.

Over the past six years, Tony Brock-Fisher, K1KP, developed a high-efficiency HF transmitter that produces 500W output. The design was adopted by Flex Radio as the basis for their new Aurora transceiver. Hear Tony’s fascinating journey in his own words at the 2025 Northeast HamXposition.

Join Don Rolph, AA1PH, at the 2025 Northeast HamXposition (“HamX”) as he discusses some experimental efforts in developing next generation emergency nets.

He’ll consider impact of forms-based messages, and the need to cover large portions of the US using RF only.

Golf-TEE is the AMSAT “Technology Evaluation Environment.”

Many components have not flown on AMSAT satellites before, including a new on-board computer, the RT-IHU. The Golf-TEE flight software will ensure that new hardware is properly tested and can operate along with the legacy components.

Burns Fisher, WB1FJ, from AMSAT will discuss the flight software on Golf-TEE, including how the multiple processors are coordinated at the 2025 Northeast HamXposition. Check the preliminary schedule for date and time.

Don Dickey, WV1W, will share his experience from over 700 activations and 71,000 POTA QSOs at the 2025 HamX. Don is also the author of the original POTA book “Successful POTA.”

This presentation will help new operators get started with portable operation and POTA, but experienced hams will also pick up new tricks to make their outings more fun and productive. Everyone will come away having learned something useful. 

Join ARRL Connecticut Section Manager Douglas Sharafanowich, WA1SFH, for a discussion of Connecticut news and activities at the 2025 Northeast HamXposition.

The magnitude of Richard Byrd’s all-out privately funded Antarctic Expedition in 1928 was going to put it in a class all by itself; perhaps one only bested by the Mars program with Space-X.  Join Mike Murphy, WU2D, of the popular Mikrowave1 YouTube Channel as he presents a history of Byrd’s south pole overflight attempt at the 2025 HamX.

Among the Friday HamX workshops is a NO-SOLDER Precision NTP Server by Bradshaw Lupton, K1TE; and Dhiru Kholia, VU3CER/WQ6W. Build a $25 GPS timekeeper, accurate to 20 nanoseconds.

Come prepared. Bradshaw has arranged a way to to pre-order parts through Amazon. (Note, bill of parts is for two GPS NTP servers. Bring a friend, share on-site, or build two units for yourself—the workshop itself is free.)

Ray Roberge, WA1CYB, will discuss AMSAT and the ASCENT group (Advanced Satellite Communications & Exploration of New Technologies) within AMSAT at the 2025 Northeast HamXposition.

Want to learn about the Software Defined Radio (SDR) that is being built for the Radio Amateur Satellite Corporation (AMSAT)?  Most satellites are hardwired to use the 2meter and 70cm bands. These are crowded and noisy. Moving up into the microwave bands gives amateurs greater flexibility with all modes. The 2-meter to 6 GHz SDR breadboard card is built and under test. Ray will talk about the high-level design and the status of the project.

Ham operators have access to a wide variety of satellites orbiting the earth. These orbiting repeaters allow reliable communications without relying on the ionospheric propagation we require on the HF bands. But there are things you need to know to be able to successfully utilize satellite communications on both the easy FM satellites and the more complicated weak signal satellites.

At his presentation “Operating the Ham Radio Satellites,” Mitch Stern, W1SJ, will review satellite technology and focus on the equipment and techniques used to make the contacts. There is nothing quite as rewarding as putting all the myriad details together to complete a satellite QSO!
