K6LCS: “How to Work Amateur Satellites With Your HT” at the Boston Amateur Radio Club Meeting Online, September 15, 2022

Boston ARC logoThe Boston Amateur Radio Club will hold its September General Meeting on the Zoom Teleconferencing Platform on Thursday, September 15. The Zoom room will open at 7:00 pm for a period of socializing, and the meeting proper will begin at 7:30.

Our speaker is Clint Bradford, K6LCS, presenting “How to Work Amateur Satellites with Your HT.” You do not need 100W of transmit power nor expensive antenna arrays to work the FM voice amateur satellites! Many hams already have the necessary equipment to “work the birds.” This presentation will walk you through ALL the steps needed to successfully work several ham satellites – including the International Space Station.

Clint K6LCS has been a ham since 1994, and found his niche in the hobby: working amateur satellites with minimal equipment and telling ALL about it! He has served a liaison between NASA, the ARISS team, and schools coordinating amateur radio contacts between the International Space Station and students (and also orchestrated a wildly successful ARISS contact). Audiences have never found his presentation slides “wordy” nor dull. Trivia questions are included throughout the session – audiences are never bored.

For reference materials, Clint has created a support Web site at work-sat.com.The Web site has become a one-stop source for ALL the citations and equipment recommendations and software suggestions made in the presentation.

Professionally, Clint was sales manager for ADI / Premier Communications / Pryme, worked for a Motorola commercial two-way dealer a couple of years, and for Ham Radio Outlet a couple more. He resides in Jurupa Valley, California, with his wife, Karen, and their rescued lab, Freja (FRAY-ya).

This will be a “perfect storm” meeting, as the club President, Vice President, and Secretary will all be unable to attend, so there will be no business portion of the meeting.

Joe Chapman NV1W / Secretary, Boston Amateur Radio Club

ARRL Foundation Grants $270,000 to Amateur Radio Clubs

From ARRL News:

08/31/2022 – The new ARRL Foundation Club Grant Program, funded by a generous grant from Amateur Radio Digital Communications (ARDC), has awarded $270,000 to radio clubs that participated in the first round of applications.

The Club Grant Program, introduced earlier this year, includes $500,000 to be awarded to radio clubs with projects that will have the most impact on amateur radio, the community, and the future of radio technology. The grants will fund transformative projects that encourage the growth of active amateur radio operators and training opportunities, education programs for student groups and schools, and club revitalization. A second round of applications to award the program’s remaining funding will open on September 7, 2022.

Twenty-four clubs were notified on Monday, August 29, that they are receiving grants. The ARRL Foundation received 128 applications in the first round, with requests totaling $1.74 million. The selection committee noted that it was difficult work deciding from many high-quality grant proposals considering the finite available funds. Radio clubs that did not receive grants in the first round may revise and resubmit applications in the second round.

An informational webinar will serve as an orientation to the program, providing information on how to apply. The webinar will take place on September 7 at 7 PM Eastern Time. Please register in advance to attend. After registering, you will receive a confirmation email containing information about joining the webinar:

Webinar: ARRL Club Grant Program | Round Two Kickoff
When: September 7, 2022 at 7 PM Eastern Time
Register: https://us06web.zoom.us/webinar/register/WN_PezTqPKCTzuwy58FWWgJ3A

The ARRL Foundation, established in 1973 by ARRL  The National Association for Amateur Radio®, administers the Club Grant Program. ARRL has long recognized that it is in the best interests of amateur radio to encourage and support amateur radio clubs. Clubs historically have recruited, licensed, and trained new radio amateurs and have provided the community setting for them to continue their education and training.

The new Club Grant Program will help clubs more easily provide and expand their important services. More information about the program can be found on the ARRL Foundation website at www.arrl.org/club-grant-program.

W8TEE, AC8GY: “Building an HF CW/SSB 20W Software Defined Transceiver” at Sci-Tech ARS Hybrid Meeting, August 30, 2022

New England Sci Tech logoThe New England Sci-Tech Amateur Radio Society will meet on-line and in-person on August 30, 2022 at 7 PM and feature: “Building an HF CW/SSB 20W Software Defined Transceiver” by Jack Purdum, W8TEE and Albert Peter, AC8GY.
 
In this talk, Al and Jack will discuss their development of a SDT, which had its beginnings for them during Field Day 2019. Using a G90 running 15W to an EFHW thrown up into a tree, Portugal, Spain, France, and numerous stations in the U.S. were contacted. Jack and Al concluded that using low power SSB during FD was viable. The G90 suffered from various drawbacks, however, so they began designing the T41 on the drive home. Their design goals were: 1) Five band HF SDT – 80-10M; 2) SSB and CW; 3) Fuzzy QRP – user selectable power from 1-20W; 4) Self-contained – no PC, laptop, or tablet; 5) “Trunk Portable” – probably too big for SOTA, but okay for POTA; 6) Reasonable cost; and 7) Open Source – hardware and software.
 
Al Peter’s educational background is in Physics and Engineering, with degrees from University of Cincinnati and University of Michigan. Al has been an electronics builder/experimenter since high school, and earned his Extra Class license in 2010. He was founder and CEO of SDRC, a major consulting firm specializing in Mechanical CAD and related engineering and manufacturing software. He is co-author of Microcontroller Projects for Amateur Radio (ARRL) and Software Defined Radio Transceiver: Theory and Construction of the T41-EP Software Defined Transceiver. Al has a number of published articles on technical/amateur radio subjects in various magazines including QST, RadCom, and QRPQ.
 
Dr. Purdum has a Ph.D. in Economics and has been licensed since 1954. He was the founder and President of Ecosoft, a software house. He has authored 20 books, mostly on programming topics, and over three dozen articles in various publications (QST, CQ, QRP Quarterly, RadCom, etc). He and Al were awarded the Bennett Prize by the Radio Society of Great Britain “…to recognize a significant contribution or innovation which furthers the art of radio communication…” for their article on their Double-Double Magnetic Loop antenna. Dr. Purdum is an avid supporter of the Open Source initiative and QRP radio operations.

RAO to Launch New Amateur Radio Learning Program for BIPOC and LGBTQIA+ Students with Support from ARDC

Nico Bezzerides, KC1PNP, writes on the STARS-radio mailing list:

I just saw this (https://public.nrao.edu/news/nrao-receives-ardc-ham-radio-grant/) and I thought this was really cool. There may even be an opportunity for us to partner with this project in order to fulfill their “connection with amateur radio clubs” requirement.


“Following a generous grant from Amateur Radio Digital Communications (ARDC), the National Science Foundation‘s National Radio Astronomy Observatory (NRAO) will soon launch a two-year project to engage BIPOC and LGBTQIA+ students in learning about the electromagnetic spectrum and the excitement of amateur— also called ham— radio. The new project, Exploring the Electromagnetic Spectrum (EMS), is expected to offer its first student-facing trainings in January 2023.

ARDC selected EMS because of NRAO’s proven track record in supporting underrepresented minority students in the sciences by combining mentoring and instruction from content experts with best practices in equity.

As a part of NRAO’s broader impacts-focused SuperKnova learning platform, EMS will combine the expertise of NRAO staff, amateur radio enthusiasts, and other subject matter experts to develop a scalable and shareable curriculum, introduce students to EMS and radio technologies through hands-on activities, and support students in attaining technical and general class licenses in amateur radio.

Amateur radio provides a hands-on entry point to understanding the radio spectrum and its practical uses, including communications, astronomy, and community emergency infrastructure and response. Early support and engagement with amateur radio has the potential to create pathways for students to a future career or lifelong hobby in the sciences. The $315,123 ARDC grant will allow NRAO to develop and execute the program for two cohorts of students. It will also result in the development of a nine-month EMS curriculum that will be freely available to school groups, community clubs, and educational institutions.

NRAO Director Tony Beasley said, “Amateur radio continues to be incredibly important to the nation and global communications, and NRAO is excited to be working with ARDC to bring a new generation and diverse communities to the field.”

Nico Bezzerides, KC1PNP, writes on the Sci-Tech ARS mailing list at 9:10 AM on August 7, 2022:

This is Nico B., KC1PNP. I’ve been an amateur radio operator for about a year and had my general ticket for about 10 months now. 

I recently got the opportunity, due to some very generously donated equipment from Bruce Tinkler N9JBT, to operate at the Bug Light lighthouse (USA 1235) up in Maine today for the National Lighthouse-Lightship Weekend. I’m very excited about it!

If we manage to get over there safely (I’m on an island, and the water looks a bit rough today w/ higher winds), then I’ll be operating QRP SSB from there from about 10am onwards, EST. If you hear me (I’ll probably be on the upper end of the 20m band most of the time, please work me! It would be great to make some contacts with STARS members.

Hope to see you on the air!

KC1PBG: “Ham Radio as it Pertains to Drones” at Sci-Tech ARS Hybrid Meeting, August 9, 2022

New England Sci Tech logoThe New England Sci-Tech Amateur Radio Society will meet on-line and in-person on August 9, 2022 at 7 PM and feature: “Ham Radio as it Pertains to Drones” by Richard Bruce, KC1PBG.
 
This presentation will dive into the days of crystal transmitters and receivers and then fast forward to the cutting-edge technology we use today. It will touch on subjects that directly connect HAM radio to drones, but also on how HAM radio is connected to numerous things we take for granted in our daily lives. 
 
Richard Bruce is a veteran and is a retired nuclear, biological, chemical and radiological weapons specialist, a retired wild land firefighter for the State of Massachusetts, and a retired security contractor. He has expertise as an FAA part 107A sUAS Commercial Pilot, as well as in search and rescue, fugitive apprehension, wild land firefighting, FEMA-trained incident command and disaster relief, and many other areas. Richard was disabled in 2018 as a result of a medical procedure gone wrong and found a new meaning to life when he got into the commercial drone community and became a ham radio technician.
