Many thanks to SWLing Post contributor, Richard, who shares the following announcement from the RAC:

Contribute to Eclipse Science and History: Research Propagation with Your Receiver!

March 5, 2024 – 

The Case Amateur Radio Club W8EDU of Case Western Reserve University in Cleveland, Ohio is excited to invite Canadian Amateurs to participate in the upcoming CHU Eclipse Data Collection Project!

We will be monitoring the reception of the Canadian time standard CHU before, during, and after the eclipse to measure the recombination time of the ionosphere. In other words, we know that the ionosphere changes in response to the presence of UV radiation in the sun by ionizing during the day and ‘de-ionizing’ at night (which is why many frequency bands propagate differently during the day and the night).

We understand how the ionosphere changes over a normal 24-hour period in response to the relatively slow transition from daytime to night time, but want to learn more about how it changes over a much shorter period (which is what the eclipse provides). We want you to help!

Our goal is to study how the eclipse affects radio wave propagation, helping us understand the ionosphere’s recombination time. To achieve this, we need your help recording Canada’s time standard station CHU for two weeks surrounding the April 8th eclipse. Anyone with a KiwiSDR or a rig capable of interfacing with analysis/recording software like Fldigi is encouraged to join the effort!

This project has already garnered enthusiastic support from various communities, including the American Radio Relay League, the Radio Amateurs of Canada, and the Ham Radio Citizen Science Investigation HamSCI.

We have over 20 stations across the continent participating, from universities and high schools to representatives from the Radio Amateurs of Canada and even a station in Mexico!

To join us and contribute valuable data, simply visit our website and follow the instructions (https://w8edu.wordpress.com/chu-eclipse-data-collection/) to set up your station and notify us about your participation.

Please reach out to [email protected] if you have any questions or comments.

Many thanks to SWLing Post contributor, Ed Efchak (WX2R), who shares the following announcement:

The Solar Eclipse Is One Month Away!

Learn How You Can Participate in Two HamSCI Roundtable Events

The last total solar eclipse across North America for twenty years will occur on Monday, April 8th. Hams across North America are asked to participate in learning more about how the ionosphere functions by getting on the air to help scientists in a series of ionospheric experiments.

Connect with HamSCI members and curious hams on Wednesday, March 27 at 8PM (Eastern) / 5PM (Pacific)*, or that same day at 10PM (Eastern) / 7PM  (Pacific)* for a Zoom presentation on HamSCI’s Festivals of Eclipse Ionospheric Science (FoEIS).  The presenters will take your questions during the 30-minute presentations.

The link to these presentations is here: https://scranton.zoom.us/j/286316405?pwd=QWdwMlFPbDlYeXg5ZDg1dmYzeFdCUT09#success

The program will start by covering HamSCI’s basis and purpose, quickly moving into why we are conducting experiments, how hams and SWLS can participate, and what we hope to learn from the event.  Along the way, we will discuss why the science behind the events is important to users of the high frequency radio spectrum – including amateur radio operators!

Learn about the HamSCI’s eclipse-focused operating events:

Solar Eclipse QSO Party (SEQP)

Gladstone Signal Spotting Challenge (GSSC)

Medium Wave Recording Event

Time Delay of Arrival (TDOA) Event

Grape 1 Doppler Receiver project

…and more!

There is no need to pre-register, create an account or log into any site. Simply follow this link at the date and times above to be taken to a Zoom meeting room, hosted by HamSCI:  HamSCI FoEIS Roundtable Zoom Link

Join us on March 27th!!   Get on the air April 8th!!

Bob Heil, K9EID, Silent Key (ARRL News)

03/01/2024

The man who defined the sound of live rock ‘n’ roll music and brought audio engineering principals into mainstream amateur radio use, Dr. Bob Heil, K9EID, has passed away at the age of 83. He was an ARRL Life Member and in the ARRL Maxim Society. A Facebook post from Heil Ham Radio paid tribute to their founder: “Bob fought a valiant, yearlong battle with cancer, and passed peacefully surrounded by his family.”

Heil founded Heil Sound in 1966, through which he created the template for modern concert sound systems for musicians like the Grateful Dead, The Who, Joe Walsh, and Peter Frampton. The talk box used on iconic live record Frampton Comes Alive! was of Heil’s design. His audio engineering products have been featured in the Rock & Roll Hall of Fame, and he was honored in 2007 with the Parnelli Audio Innovator Award for his impact on the live sound industry. “My life has been about achieving great sound, whether on the concert stage or in the amateur radio world,” Bob Heil recounted in 2022. “I’ve watched Heil Sound go from a regional sound company to a world-class microphone manufacturer. This company has been my passion,” he said.

Parallel to his commercial and artistic success in live music, was his passion for amateur radio. He was active in ham radio from a young age and merged his expertise in audio engineering with his love for radio. Heil Ham Radio was founded to produce microphones, headsets, and other gear for radio amateurs with an emphasis on high-quality audio.

Heil was known as a mentor who enjoyed helping others find success in ham radio. Recently, his grandson Charlie Hartley, KF0OOP, became a licensed ham to surprise Heil for his birthday. The pair attended the ARRL Midwest Convention/Winterfest in St. Louis, Missouri, on January 27, 2024.

Heil was a generous donor to amateur radio organizations, including ARRL. Recently, he donated a host of new audio gear to the Hiram Percy Maxim Memorial Station, W1AW.

His generosity and kind nature will be missed by many, including ARRL Director of Development Kevin Beal, K8EAL. “Bob was a titan in many areas. He was generous with his time, offered keen insights, and had the heart of a philanthropist in the ARRL Maxim Society,” Beal said. “He was a gentleman to his core, making friends easily and everywhere he went, from rock stars to captains of industry. I consider it a real privilege to have become a friend to him, too, all because of amateur radio.”

Heil was known for his passion for AM operations. He served for many years as an on-camera host of the Ham Nation podcast. Tributes to Heil have been flooding social media, including from his co-hosts.

ARRL President Rick Roderick, K5UR, said Heil’s passing is a significant loss. “Bob Heil’s technical achievements that brought high-quality audio to amateur radio pale in comparison to his generosity and willingness to help his fellow ham. He’s long been known as someone eager to help mentor and teach. His legacy on our hobby will be long-lasting. Our thoughts are with his loved ones.”

Bob, you were a true radio ambassador, and we all benefitted from your enthusiasm and passion for decades to come. Thank you.

Many thanks to SWLing Post contributor, Bill Meara who shares the following article from the excellent SolderSmoke Podcast:

7J6CBQ on Okinawa — And a Translation of a Science Fiction Novel about Ham Radio in China

The article about Sergeant Malik Pugh USMC on Okinawa brought back memories from the 1990s. David Cowhig was 73 Magazine’s Hambassador on Okinawa — I had the same “position” in the Dominican Republic.  David and I were both in the Foreign Service;  we joked that 73 had afforded us our only chances to be ambassadors of any kind.  David’s Okinawa QSL and the opening from his initial report to 73 magazine appear above.  You can see more here:

A couple of my own “dispatches” as Hambassdor to the Dominican Republic appear here:

Back in the 90’s David sent me an old QST Magazine.  I wrote about this on the SolderSmoke blog:

Later, I learned about another “Hambassador” who was still active as a radio amateur: Ron Gang 4X1MK:

Finally (and this is really cool):  David Cowhig has been putting his language skills to good use, translating Chinese written material.  He sent me his translation of the opening chapters of a Chinese science fiction novel about ham radio.   Readers of the SolderSmoke Daily News will like this:

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Andrea Borgnino, Paul, and Dennis Dura for the following tips:

BBC World Service announces Emergency Radio Service for Gaza (BBC Media Centre)

It will provide listeners in Gaza with the latest information and developments as well as safety advice on where to access shelter, food and water supplies

BBC News Arabic has today (1 November) announced an Emergency Radio Service for Gaza in response to the conflict in the region.

The emergency service – Gaza Daily – will broadcast vital news daily to the people of Gaza during this time of urgent need.

It will provide listeners in Gaza with the latest information and developments as well as safety advice on where to access shelter, food and water supplies.

Produced in Cairo and London and broadcast on medium wave, the service will initially run one programme a day at 1500 GMT from Friday 3 November. A second daily update will be broadcast at 0500 GMT from Friday 10 November.

The BBC World Service has a history of responding to emergency situations globally. Most recently, in May 2023 during the conflict in Sudan BBC News Arabic began an emergency radio service. In February 2022, the BBC News Ukraine service began extended TV bulletins following the invasion of the country. The BBC also previously launched a service for Gaza in 2014 following a summer of conflict.

Liliane Landor, Director, BBC World Service, says: “BBC News Arabic are extremely well-placed to offer this vital service for the people of Gaza at a time of greatest need. Their expertise and specialist knowledge of the region alongside the BBC’s reputation as the most trusted news provider, means we can reach civilians in Gaza with the information they need.”

Notes to editors: The Gaza service will be broadcast on MW 639kHz for morning and evening episodes.

FCC Wants to Bolster Amateur Radio (Radio World)

Commission will vote in November on plan to remove outdated technical restrictions

FCC Chairwoman Jessica Rosenworcel says the FCC plans to “incentivize innovation and experimentation in the amateur radio bands” by getting rid of outdated restrictions and providing licensees with the flexibility to use modern digital emissions.

The commission at its November meeting is expected to take action on a Report and Order that would eliminate the baud rate limitation and establish a bandwidth limitation in the amateur radio bands below 29.7 MHz.

The order being circulated for tentative consideration by the commission would remove the baud rate limitation — the rate at which the carrier waveform amplitude, frequency and/or phase is varied to transmit information — for data emissions in the amateur radio bands, the FCC says. The current baud rate limits were adopted in 1980.

The order would implement a 2.8 kilohertz bandwidth limitation in place of the baud rate in amateur radio bands. The 2.8 kHz limitation is consistent with the commission’s treatment of other wireless radio services, the FCC says.

The current rules limit the baud rate for high-frequency amateur radioteletype/data transmissions to 300 baud for frequencies below 28 MHz (except in the 60-meter band), and 1200 baud in the 10 meter (28-29.7 MHZ) band. [Continue reading…]

Ham Radios Crowdsourced Ionospheric Science During Eclipse (EOS.org)

Amateur radio operators who study space physics and the upper atmosphere probed the ionosphere’s response to the 2023 annular solar eclipse using shortwave transmissions.

On 14 October, millions of people in North, Central, and South America peered through safety glasses and other viewing aids at the partially obscured Sun. Simultaneously, thousands of folks experienced the annular solar eclipse in a different way: through transmissions sent and received over amateur radios.

Before, during, and after the eclipse, ham radio operators pinged signals off the ionosphere and connected to people hundreds or thousands of kilometers away. The experiment, part of the Ham Radio Science Citizen Investigation (HamSCI), is gathering hundreds of thousands of those contacts to investigate how the ionosphere responds to the temporary loss of sunlight during an eclipse.
