Sturdy Repeater Returns to the Air

Sturdy Memorial Hospital ARCRay Cord, K2TGX, writes on the Sturdy Memorial Hospital ARC mailing list:

Just to let you know that the K1SMH 147.195 Sturdy Memorial Hospital repeater has returned to the air as of about 1330 today [March 28, 2021] thanks to the efforts of: Pierre Guimond, N1EZT; John Bellissimo, KA1EWN; Steve, N1LEO and Bill, WB1DJM. Bill rebuilt the Super StationMaster that the repeater is now using while the damaged JAG 4 element folded dipole array was rebuilt from the damage it received in the tower fold-over. We lost about five feet in elevation and we are on a different antenna so you may notice some difference in coverage on the fringes.

It is good to get it back on the air and hope to hear activity soon. If I missed anyone who helped in this endeavor, please accept our thanks.

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 contact@mmra.org

———-

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.

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.

AK1WI: “Adventures in Home Brew SDR Design” at New England Sci-Tech ARS, April 27, 2021

AK1WI homebrew SDR radioAK1WI will present “Adventures in Home Brew SDR Design” at the New England Sci-Tech Amateur Radio Society on April 27, 2021 at 7:00 PM. 

In this talk, Derek will describe his multi-year project to develop the hardware and software for a stand-alone SDR system using the “Teensy” family of microcontrollers from PJRC.  In particular, it uses the Teensy Audio Library structure, hence its name “AudioSDR.”   The software is now freely available from GitHub.

Derek will describe the origins of the project from a graduate course he was teaching in 2010, and how it was not initially intended for ham radio, but rather as an exercise in applied DSP (digital signal processing).   He will describe in very broad terms the structure and operation of the system.    Math will be kept at a minimum. 

The talk will also cover the associated hardware for the RF front-end and the LCD display, as well as how the system is controlled, and the software structure for the Teensy Audio Library coding.   We will look at (extremely) over-simplified seudo-code to demonstrate concepts of real-time software.  We will write such code for an SDR version of the humble crystal-set – the simplest of all radios.

Derek will also discuss current developments and future enhancements for AudioSDR, including the addition of a transmit function to make it a true transceiver. 

If feasible we will have a demonstration of the operation, or at a minimum, pre-recorded sound clips of the output.

The January [PART of Westford] meeting will be held on Tuesday, April 20, 2021, beginning at 7:30 PM via Webex video conference.  

 

The presentation will be “Giant Antennas of the Navy” given by George, K1IG. When you’ve got to maintain continuous world-wide communications with ships and submarines, ordinary antennas just won’t work. The Navy’s antenna dimensions are measured in miles, not meters (this includes the vertical dimension), and handle megawatts of power. You may recognize some of the designs, but theyre bigger, a LOT BIGGER, than any ham has used. Attend our meeting and see what they look like!

QRA Zoom Meeting Gets a “Surprise Visitor”

QRZ screenshot of JADon Melanson, W1DM, writes:

Last night’s [April 15, 2021] Quannapowitt Radio Association Zoom meeting featuring the W1AW Video Tour turned into a surprise for a few of our members.  As the meeting was about to take place another ham operator signed into the meeting. His name is Skip Y. Sugimoto, JE2HCJ, from Japan.

It’s a funny story, according to Bob Reiser, AA1M, QRA club secretary. It seems when Bob was sorting his personal contacts for one of his upcoming ARRL awards he added Skip’s e-mail to our Zoom meeting invite without really knowing it. So Bob was quite surprised when Skip asked for the login.

Nothing was said to any of the members until Skip signed in. Skip started his day off by watching the video and then answered a few questions from some of the members. It was a very enjoyable evening by all the members and guests who attended. Skip was very impressed with the video and was welcomed by all.  Skip promised to keep in touch and possibly attend the next month’s meeting before he had to log out to go to work .

The QRA would like to thank the ARRL, Jeff Fox, K1GF, and W1AW Station Manager Joe Carcia, NJ1Q, for making the video. It makes a W1AW tour possible for those unable to physically visit.
