Report on Field Day 2023

ARRL Field Day, June 24-25, 2023

For this year’s ARRL Field Day on June 24-25, the Waltham ARA partnered with the Montachusett ARA (MARA). We operated from the summit of Mt. Wachusett in Princeton, MA in Class 3A (3 transmitters, in the field on emergency power). We also operated a “Get on the Air” (GOTA) station for new hams, future hams, and Technician class operators. Over 1,000 contacts were made with other FD participants around the country, and in a few other counties, including an FT8 digital contact with New Zealand.

Field Day 2023 Photo Album

Though off the grid, the CW and Digital stations shared a single log file using N1MM Logger+ and an on-site wifi network. The columns in the log excerpt below are: Time, Call, Frequency, Mode, Class, Section. For example, the first contact shown was on FT8 on the 15-meter band with KF0X in Arizona:

Next Meeting – Wednesday, February 22, 2023 at 7:00 PM – Online Only

Zoom opens at 6:30 PM for informal pre-meeting meeting.

For logistical reasons, this meeting will be online only. We hope to return to hybrid meetings at some point.

Guest speaker Fred Cirera, W6BSD will present, “Digital Voice Modes for Amateur Radio“. You don’t need a General or Extra class license to enjoy QSOs with people worldwide. All amateur license classes can use Digital Voice (DV) modes such as Fusion, D-Star, DMR, and many others to connect with people throughout the US and other countries using digital repeaters or amateur hotspots. During his presentation, Fred will discuss the differences between the DV modes and how the backend infrastructure works.

February 27, 2019 Meeting Program Change: Magnetic Loop Antennas

George Maier, W1LSB, has rescheduled his presentation on the National Company of Malden.  The new date is April 24.  George decided that taking a trip to meet his newborn grandchild took precedence over keeping the original date.   Good call, George!

But we have arranged a new program for the February 27 meeting.  Ted Robinson, K1QAR, will give a presentation on High-power Magnetic Loop Design.

February 27, 2019 Meeting Program: National Radio Company of Malden

The National Company of Malden, Massachusetts was a world class manufacturer of commercial and amateur radio communications equipment from the early 1930’s until the late 1960’s. Their HRO series was used extensively by numerous allies during World War II, and can be credited with helping in the effort to receive coded messages from behind enemy lines. George Maier, W1LSB, will take us through the company’s history, products, and talk about some National employees that he knew personally.

SKYWARN Training Session at WARA May 30 Meeting

The May 30 WARA meeting will be a severe weather spotter training session. The training is presented by Rob Macedo, KD1CY, in association with the National Weather Service SKYWARN program. Everyone age 16 and older who stays to complete the training will be able to become trained NWS weather spotters.

The training includes a two-hour thirty-minute computer-based presentation, which discusses the development of thunderstorms, the criteria for “severe” thunderstorms, as well as the cloud features associated with severe thunderstorms and tornadoes. Additional information will be presented about winter storms and proper snow measurement and reporting of coastal flooding, river, stream, and urban flooding and rainfall measurements. The session will also present the procedure for reporting weather information to the National Weather Service. Safety procedures for the various forms of summer severe weather (severe thunderstorms, tornadoes and lightning), winter storms, and flooding will also be covered in the training session. Anyone attending should bring a pen or pencil and bringing a notebook is optional.

The number of seats is limited, so per-registration is strongly advised. Use the following link:
