Tuesday, June 17: “Aircraft Tracking using SDR” by Peter Morrison, AC1KY.

Description: In this presentation, Peter Morrison will discuss how anyone can use low cost software-defined radios to track aircraft using ADS-B (Automatic Dependent Surveillance Broadcast) signals. He will provide some history of the development of ADS-B and will also talk about aircraft patterns around Beverly.

Bio: Peter was first licensed in 1960 in Montreal and still holds a Canadian call sign, VE3IDX. He moved to the U.S. in 1981 and acquired U.S. call sign AC1KY several years ago. Peter is a retired EE who specialized in computer design. His former employers include Raytheon, Wang, Digital, and Intel. For many years Peter travelled back to Canada to join a group of friends to operate for Field Day. Computers currently occupy a fair chunk of his time.

Please note: Peter will be presenting in person at [New England Sci-Tech], but you can also choose to participate over Zoom, as always.

The next [Boston Amateur Radio Club] general meeting will be held on Thursday, May 15, 2025, at 7:30 pm, at Artisans Asylum in Allston and on the Zoom teleconferencing platform.

This month’s speaker is Peter, KC1HHO, presenting Introduction to National Traffic System and the Radiogram.

This will be an interactive talk so be sure to attend in person if you can. As always, the meeting will be preceded with a half hour of social time beginning at 7:00

Jeff Stuparits, W4DD, will present “Locating Power Line Noise and other RFI” at the Sci-Tech Amateur Radio Society hybrid meeting on May 13, 2025 in Natick and online.

Description: Radio Frequency Interference (RFI) can be generated from many different devices and can decrease or totally eliminate your ability to hear stations on your HF or VHF radio.  In today’s modern world of numerous electronic devices in and around our homes, it’s not a matter of if you have RFI, but of how many devices are generating it and how significantly is it interfering with your Ham Radio receiving ability.  RFI can also affect other services like AM radio, FM radio, Over-the-Air TV, DSL Internet, public safety communications, and even cellular telephones.  Jeff became interested in RFI about fifteen years ago when it affected his ability to enjoy ham radio for contesting, weak signal work, and QSO’s.  In addition to providing information on locating RFI, he will also have a few pieces of hardware for show and tell and discuss how he approaches RFI problems. 

Bio: Jeff is retired from Verizon Wireless where he worked in the Advanced Technology Group on spectrum issues, including cellular spectrum optimization and FCC spectrum auctions.  In addition to his 20 years in cellular, earlier in his career he worked in Telephone Operations and Air Defense Communications.  Jeff’s background includes a EE, an MBA, and he is a licensed PE.  Additional information about Jeff can be found on his QRZ web page or in the August 2022 QST Member Spotlight.

Max Kendall, WØMXX, will present “RF PCB Design” at the Sci-Tech Amateur Radio Society hybrid meeting on April 29, 2025 in Natick and online.

Description: 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 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.

Bio: Max is an 8th grader at Benjamin Franklin Classical Charter Public School. He is the president of STARS radio club at New England Sci-Tech, the president of the 4-H Science Explorers, a mentor at the Medway Library Arduino club and STEAM classes, and founder of the New England Weather Balloon Society.
