KB1MGI Fox Active in Chelmsford, May 16, 2021

John Salmi, KB1MGI, writes on NEMassFoxHunters list on May 16, 2021 at 1:37 PM:
I placed my UHF 432.300 MHz Fox transmitter at the George B B Wright Reservation at 120 Parker Road, Chelmsford. See attached Map pdf.
To activate the 432.300 MHz transmitter press DTMF tone 2 for two seconds. The fox will transmit a steady tone and CW ID for 30 seconds on, 30 seconds off for 15 minutes. then you need to press the DTMF tone 2 again to reactivate.
It should last a few days, but that depends on the amount of activations.

KD1LE Fox is Operating in Westford, May 14, 2021

Stan Pozerski, KD1LE, writes on NEMassFoxHunters list on May 14, 2021, 10:27 AM: 


The fox is out as of 9:30 this morning. It is on the regular 146.565 MHz frequency transmitting every five minutes. Sending an * within five seconds of the end of transmission will halve the cycle time if you’re in range.

It was a beautiful morning for a walk, the trees and lilacs are in bloom and the turtles are sun bathing. But if you were thinking about a picnic lunch you are a few years too late. Since everyone found the intersection of Gould Road and Westford Road [in Westford, MA] last time it’s not a bad place to start.

“Saving the MIT Radome”

Green Bldg rooftop MIT campusPerched atop the MIT Cecil and Ida Green Building (Building 54), MIT’s tallest academic building, a large, golf ball-like structure protrudes from the roof, holding its own in the iconic MIT campus skyline. This radar dome — or “radome” for short — is a fiberglass shell that encases a large parabolic dish, shielding it from the elements while allowing radio waves to penetrate. First installed in 1966, it was used initially to pioneer weather radar research. As the years passed and technology evolved, the radome eventually fell out of use for this purpose and was subsequently slated for removal as MIT began a major renovation and capital improvement project for the building. That’s when the student-led MIT Radio Society, who had found creative new uses for the radome, sprang into action to save it — and succeeded. [Full story]

KC1JUO: “Software Defined Radio” at Minuteman Repeater Association Meeting, May 19, 2021

MMRA logoHam Radio and Software Defined Radio – An Overview, Some History, and a Demonstration
Charles Miller KC1JUO

May 19, 2021 at 7:30 PM

Location: ZOOM — Members: login to the Minuteman Repeater Association webpage for the link; Non-members: send an email to


Charles will share a bit about how he sees Ham Radio and Software Defined Radio as not only being connected but also fundamentally similar and complementary.  He will present an overview which is essentially his journey and perspectives of the topic.  The hope is to share why he finally got licensed, why he thinks the hobby is so fantastic, talk about a few radio frequency bands and describe how they are being used.  Charles will wrap up the talk with a demonstration of using software and hardware to compose and view frequency bands discussed.

Charles has been licensed since 2017 with the call sign KC1JUO.  During his many decades of tinkering, he has built and broken much.  He is a Gordon Engineering Fellow with a Computer Science degree from Boston University and a Master of Information Systems from Northeastern University.   His current career focus is on Cyber Systems Engineering, receiving his CISSP certification in 2019.  Having spent most of his career as a Technical Consultant prior to 2005, he joined Raytheon in 2005.  Raytheon has a long history of Ham Radio relevant technology:  Percy L. Spencer (W1GBE) was a critical part of Raytheon’s history and has been an inspiration for Charles for both Ham Radio and the exploration of Software Defined Radio.

The Pocahontas Radio Club (an informal group of old and new friends) and the owners and trustees (N1HSY and N1HOW) are pleased to announce that the Topsfield MA repeater (147.285 PL 100.0) has been completely rebuilt with a new tower, new antenna, new hardline, new weatherproof repeater enclosure and refurbished or replaced electronics. The “Pokeys” hold a ragchew net 7 days a week at 0830 EDT and all are welcome to join in at any time to make new friends and renew old acquaintances. Special thanks to Doug, N1LHP, and his many friends for their tireless work.

Also, he is the radio consultant for Natick Police and Fire Departments for the past 30 years.

He retired in 2019 from Raytheon as a Principal Electrical Engineer specializing in the design and maintenance of test equipment. He worked at Raytheon plants in Waltham, Andover, Sudbury, and Marlboro over his 38 years with Raytheon.

After our feature presentation we will socialize and enjoy a virtual Spring lunch together.

W1DAN: “FCC RF Exposure Rules and Compliance” at Sci-Tech ARS Meeting, May 11, 2021

New England Sci Tech logoJoin the Sci-Tech Amateur Radio Society on Tuesday, May 11, 2021 at 7:30 PM for a presentation on “FCC RF Exposure Rules and Compliance” by Dan Brown, W1DAN.
Updated FCC Radio Frequency Exposure Rules went into effect on May 3, 2021. Dan will explain what this means. After May 3 of this year, any new station, including SOTA, POTA, and Field Day stations, or any existing station modified in a way that’s likely to change its radio frequency emission profile — such as different antenna or placement or greater power — will need to conduct an evaluation by the date of activation or change.

Born and raised in New Orleans, W1DAN caught the shortwave bug in the early 1970s as he discovered listening to shortwave broadcast stations, but soon discovered ham radio. Dan obtained his license in 1978 and got on the air on CW with a Heath Apache and Hallicrafters SX-101A – and modified them. Since that time he has enjoyed not only the vintage gear and the AM mode, but modern Software Defined Radios with DSP, Class E RF amplification as well as digital modes such as PSK-31. While he does not claim to know everything about radio he is happy to assist fellow hams with technical questions, promote STEM education and citizen science. W1DAN is also the president of the Wellesley Amateur radio Society, works as a broadcast engineer in Boston and lives in Natick, MA.

K9LA: “Solar Cycle 25, Space Weather, and Practical High Band HF Antennas” at Nashoba Valley ARC Meeting, May 20, 2021

Nashoba Valley ARC logoPhil Erickson, W1PJE, writes on the NVARC mailing list:

We’re pleased to announce that the May [20, 2021 Nashoba Valley Amateur Radio Club] meeting will feature Carl Luetzelschwab, K9LA, speaking on the topic “Cycle 25 Update and Understanding Space Weather”.  NVARC is very fortunate to have K9LA, who is in demand nationally and is a regular at Dayton Hamvention’s forum talks.  He also made presentations in 2021 both at K3LR’s Virtual Contest University and 4Z1UG’s QSO Today Virtual Expo.

Summary: Carl K9LA will discuss the predictions for and the progress of Solar Cycle 25, including what to expect in terms of propagation throughout 2021 and as Cycle 25 ascends. He will also review simple antennas for 15m, 12m and 10m as Cycle 25 ramps up. He will then briefly review websites with space weather data and how to tie this important data to HF propagation conditions. Finally, he will highlight real-time propagation websites that allow us to assess what’s happening right now.

Biography: Carl Luetzelschwab K9LA started his radio career as a short wave listener in the late 1950s. He received his Novice license (WN9AVT) in October 1961, and selected K9LA in 1977. Carl is a graduate of Purdue University and was an RF design engineer until his retirement in 2013. Carl enjoys propagation, DXing (he’s at the Top of the Honor Roll), contesting (he was NCJ Editor from 2002-2007), experimenting with antennas and restoring/using vintage equipment.

He and his wife Vicky AE9YL enjoy traveling, which has included DXpeditions to Syria (YK9A in 2001), to Market Reef (OJ0/AE9YL and OJ0/K9LA in 2002) and numerous trips to ZF (Vicky is ZF2YL and Carl is ZF2LA). Carl is currently the ARRL Central Division Vice Director. He has received the Bill Orr W6SAI Technical Writing Award, the YASME Foundation Excellence Award and the Indiana Radio Club Council Technical Excellence Award.

[W1PJE: Carl maintains an extensive website at with selected articles and presentations about propagation and solar topics, grouped into categories – Monthly Feature, Timely Topics, Basic Concepts, Tutorials, General, 160m, HF, VHF and Contesting.  It’s well worth your time.]
