13 Colonies Massachusetts, is looking for a few new ops to join Team K2H.
13 Colonies takes place every July 1-7. We’re looking for volunteers who can operate for at least 2 hours per day for at least 4 of the 7 days.
Operating as K2H is a blast. You become the DX, and stations want to work you. You don’t have to be a contest op to volunteer. Anyone interested and available is welcome. As part of team K2H for the past few years, we have made around 20,000 contacts.
If you are interested, please contact Larry, W1AST, 13 Colonies Massachusetts state manager, at W1AST@arrl.net before May 15th.
Thanks and 73,

I hope to see you at this year’s HamX! – www.HamX.org
From Nashoba Valley ARC Signal, April 2025:
The Groton Road Race Committee has requested the assistance of the Amateur Radio community for the Race on May 4. NVARC and the ham community have been providing situational awareness, health and safety communication for this event for over three decades.
The course circles Groton Hill, starting and ending at the Groton Hill Music Center. This is the third year the Race has followed this course. The planned event schedule this year is similar to 2024; the two main races start shortly after 10am. The communications support that we provide is expected to start around 9am and we should be done shortly after 1pm.
The Groton Road Race continues to be a major event for Amateur Radio in North Central Massachusetts. Those of you who have joined us in previous years know that the runners sincerely appreciate our presence. Many say so as they run past. This event is so large that Police Departments and other public safety organizations from several communities come to assist the Groton PD. Part of our role is to provide the communications from the Groton Police to these out-of-town officers who come to help with this event.
Contributing to the public good is one of the reasons Amateur Radio exists. Our public service events are a key opportunity for us to show our colors, volunteer our skills and equipment, and demonstrate why it is in the public’s interest to continue to allocate precious RF spectrum to our the Amateur Radio Service. The Groton Road Race is a low-stress event and a great way to gain more experience with the public service aspect of amateur radio. Please consider joining us on the 4th.
If you are a new Ham or know of another Ham who is interested in helping at these events but unsure of what is expected or what equipment may be needed, please do not hesitate to introduce yourself (or them) to me.
The Groton Road Race Committee and the Groton Police Department repeatedly praise and express their appreciation for our assistance in providing communications for this event for many years. I do hope you will be able to join us this year; please let me know.
Thanks and 73,

Students will have the opportunity to use FT8 and talk on the 446.675 repeater. [Algonquin ARC] Members can monitor the repeater and maybe have a chance to talk to the students and possibly answer some trivia questions. It’s not known when an interested student might show up during the time period, so just listen and wait.

From Algonquin ARC QRZ Newsletter, April 2025:
The project to deploy a Winlink node at our Marlborough repeater site was completed this past month. George, N1ABC, led the project that was sponsored jointly by the Algonquin Amateur Radio Club and the Marlborough Emergency Management Agency. The Winlink system provides message forwarding communications via radio worldwide. It is an integral part of our amateur radio traffic system that supports our regional Emergency Management services. This new node provides coverage to the western Middlesex county and eastern Worcester county areas.
The node is located at our N1EM/R repeater location on the Sligo Hill water tower.
Frequency: 145.090 MHz
Call: N1ABC10
The AARC provided the funding for the Motorola radio, modem and internet hardware. Marlborough Emergency Management provided the antenna, feedline and their installation. Thanks to the Minuteman Repeater Association for providing the internet access. Also thanks to Stu, W1SHS, for his help understanding the software, Roger, WA1NVC, for the help with the radio programming, and Ron, N1CNG, for help with the equipment installation.

at 1100 hrs. Auxiliarists on the net were advised of the upcoming training in April and the mandatory
TCO radio training. Hopefully there will be a Zoom media training presentation at a later date for all

We will be removing the Billerica repeater from its current site on April 4th. It will be off the air for 2 – 3 weeks while the antennas are relocated to the new site. Some work will also be done to the equipment itself during the downtime. The Burlington repeater on 145.43 should provide adequate coverage in the Billerica area during this period.
We are in need of some people to help with the removal on the 4th. The tower is hinged, so it will be lowered and everything removed. We also need to bring the antennas, equipment, and some empty racks that are in the repeater room down to the loading area to be put on vehicles.
We currently have four volunteers but could use four more. We will meet at 300 Concord Rd, Billerica at 9AM on the 4th. I would estimate it will take about four hours to complete the work.
Please reply if you are interested in helping.

I will be doing an encore FreeDV Zoom and on-the air tutorial for WARS members on
If you missed last Monday’s meeting, you can join us for this meeting. I will cover the basic setup of FreeDV.
For those who were at last Monday’s meeting we will try the latest version of FreeDV to see how well the new vocoder works.
We will use 50.190 MHz for our on the air tests while we are on Zoom.
I recommend using a PC headset/microphone which plugs into a USB port on your computer. This will be used for the FreeDV audio. When you log into the Zoom meeting, use the computer internal speaker and microphone.
For the meeting I recommend you use the same computer for both Zoom and FreeDV. This will give you the ability to share your screen on Zoom if you have any problems so we can observe and debug any issues you may have.
I will focus the meeting on Windows operation as I am not familiar with Mac or Linux.
You must have a known-good method of connecting your computer to your radio. If you have used FT8 or FLDIGI successfully, you can use the same setup for FreeDV.
The latest version of FreeDV uses the AVX instruction set in the processor of your PC for the new high-quality vocoders. Most of the latest processors have the AVX instruction set.
Before the meeting please check to see if your processor has the AVX feature set. Follow the instructions in this web site
https://www.ghostarrow.com/how-to-know-if-my-cpu-supports-avx-instructions
If you have a Windows 11 computer and your processor has AVX, you may need to enable the AVX feature in your computer BIOS. Follow the instructions here (skip step 1, start at step 2) to enable AVX
[For Zoom details, contact Charlie Bures, WA3ITR, at c.bures@comcast.net]
The Massachusetts – Rhode Island STM Report for February 2025 is now available at https://ema.arrl.org/massachusetts-rhode-island-stm-report-for-february-2025/. Note new traffic handlers, a new virtual traffic training net, a Treasure Hunt, APRS-NTS Gateway and more.
The Nashoba Valley Amateur Radio Club‘s March meeting is Thursday, March 20th at 7:30 PM at the Pepperell Community Center (in Pepperell). We start gathering at 7 PM to socialize before the meeting starts. NVARC has a special treat in store for you at the March meeting. Dale Clement, AF1T, will be talking about antennas. NVARC has had Dale speak before, but we have enough new members and new hams that we just couldn’t pass up the opportunity to have him speak again. Dale demonstrates practically and visually how and why antennas work. Trust me: He’s entertaining, and you will learn a lot. Do not miss this meeting!
The Board of Directors would also like to discuss possible plans for the N1MNX repeater system with membership, April elections of officers, Field Day in June, etc. So please plan on attending the meeting.

March 18, 2025: “How to Become a POTA Hunter” by Harold Kramer, WJ1B.
Description: Parks on the Air, POTA, is one of the fastest growing and most popular programs in Amateur Radio today. This presentation will provide an overview of the Parks on the Air program and will emphasize the tools, techniques, and practices for becoming an effective POTA Hunter. Hunters are stations that are not operating in a park, but rather, usually at their home stations. Hunters are essential to the POTA program because without Hunters, the Activators, stations located in a park, would have no one to work!
Bio: Harold retired eight years ago as the Chief Operating Officer of the ARRL and Publisher of QST. He still writes Product Reviews and Classic Radio columns. He is currently a volunteer at the ARRL Lab and a member of the ARRL Board’s Historical Committee. He is an avid POTA Hunter with over 2,600 confirmed parks. Harold was first licensed as KN1ZCK at age 14. He spent his entire career in the cable television and broadcast industries. Before joining the ARRL, Harold was the Chief Technology Officer of Connecticut Public Broadcasting. He holds Bachelor’s and Master’s degrees from The University of Connecticut. Here is a link to Harold’s website: http://www.wj1b.com
The USTNR [Uncommon Service to Nautical Radio] plans to activate the USS Massachusetts on April 19, 2025, according to Rick Emord, KB1TEE.
“We plan to get on the ship around 0800 to celebrate scouting. We will pack up at 1530. Come on down if you can only spend a few minutes or any times, just come to the ship’s gift shop and sign the page with my name on it.”
