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Commission will vote in November on plan to remove outdated technical restrictions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says the FCC plans to “incentivize innovation and experimentation in the amateur radio bands” by getting rid of outdated restrictions and providing licensees with the flexibility to use modern digital emissions.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.

How to Earn the W9IMS 2023 Checkered Flag Award

Once, Twice, Three Times a QSO: How to Earn the W9IMS 2023 Checkered Flag Award

By Brian D. Smith

Two out of three ain’t bad, proclaims the late ’70s classic rock song. But three out of three gets you the Checkered Flag Award from W9IMS.

That’s another way of reminding you that the third Indianapolis Motor Speedway special event of 2023, honoring NASCAR’s Verizon 200 at the Brickyard, will take to the amateur radio airwaves starting at midnight Indy time (0400 UTC) on Monday, August 7, and ending at 11:59 p.m. Sunday, Aug. 13 (0359 Monday, August 14 UTC).

Those who chalked up contacts or receptions during both of the first two special events in May – commemorating the IndyCar Grand Prix and the Indianapolis 500 – now have the opportunity to complete the clean sweep and qualify for the colorful Checkered Flag certificate.

But even if you’re just getting up to speed on the Speedway special event, or have caught only one of the two special events so far, you’re still in the running – not for a Checkered Flag Award (that’ll have to wait till 2024), but for one or more of the three collectible QSL cards that commemorate the individual races.

How to find W9IMS? The station operates primarily on 20 and 40 meters, but sometimes adds 80 meters later in the week (and occasionally 2 meters on Race Day for locals and fans in the stands at the Speedway). Preferred frequencies are 14.245 and 7.245 SSB, plus or minus QRM.

And the following suggestion will enhance your chances of putting W9IMS in your log:

  1. Check DX Summit (www.dxsummit.fi) for spots listing the current frequency or frequencies of W9IMS, if any. By typing “W9IMS” in the search box at upper right, you can customize it to show reports for only Indianapolis Motor Speedway special events. Naturally, you’ll be interested in only the ones from August 2023.
  1. Follow this link to the W9IMS web page (www.w9ims.org) and look for the heading, “2023 Operating Schedule.” Click on the NASCAR 200 link, which opens into a weeklong schedule listing individual operators and their reserved timeslots. Your odds of catching W9IMS on the air improve significantly during these hours.
  1. Prime operating time on weeknights is 6 to 10 p.m. Indy time (2200-0200 UTC). However, W9IMS can appear anytime, even on two bands at once, between 0400 Monday, August 7, and 0359 Sunday, August 13.
  1. Operators often get on the air at unscheduled times. That’s why DX Summit is your best bet for locating W9IMS’s current frequency (or frequencies).
  1. If you plan on applying for the 2023 Checkered Flag Award, remember that the three required W9IMS special event QSOs (or reception reports) must come from all of the year’s three races – the Grand Prix, the 500 and the Brickyard. Making three contacts during the coming week still earns you the colorful Brickyard QSL card, but no extra credits toward the certificate.
  1. Remember that the published schedule can be shortened by adverse circumstances, such as noisy band conditions, local thunderstorms or a lack of calling stations. Don’t wait till the final day and hour to chase W9IMS!
  1. If you want to get off to the earliest possible start, keep an ear on 20 meters at midnight Monday (Indy time) and listen for a YL operator. Cathy Harris, W9QKR, is slated to kick off the festivities from 12-2 a.m. (0400-0600 UTC).

2023 W9IMS Special Event Station Details!

W9IMS Accelerates into Another Special Event Season – with a Chance for an Indy Racing Certificate 

By Brian D. Smith

It’s back to the track for collectors of W9IMS cards and certificates.

The first of this year’s three special events tied to the major races at the Indianapolis Motor Speedway will begin at midnight Eastern Time (0400 UTC) this Sunday, May 7, and continue through 11:59 p.m. (0359 UTC) the following Saturday, May 13.

And for hams and SWLs, your chance for a 2023 Checkered Flag Award begins – and could end – with it. To earn the certificate, you’ll need to contact or tune in W9IMS during all three special events this year: the Grand Prix, the Indianapolis 500 (May 22-28) and the NASCAR 200 at the Brickyard (August 7-13).

Catch W9IMS during Grand Prix week and you’re one-third of the way to Victory Lane. Miss it and you’ll have to wait till 2024 for another shot at the certificate.

So when and where do you find W9IMS? Any time of the day or night is possible, but prime time is from 6 to 10 p.m. (2200-0200 UTC) weekdays, and the prime bands are 40 and 20 meters (generally around 7.245 and 14.245 MHz). And this year, improved solar conditions could prompt a rare move to 15 and 10 meters, likely around 21.350 or 28.340 MHz.

The choice of frequencies will be gametime decisions based on a variety of factors, including QRM, band openings and the number of calling stations. So your surest move is to check W9IMS spots, which are frequently posted on DX Summit (www.dxsummit.fi).

While some on-air times are unscheduled, you can also increase your odds by going to the W9IMS QRZ page (www.w9ims.com) and clicking the Grand Prix link under the heading “2023 Operating Schedule” – which displays the shifts that operators have already signed up for.

If time is running short, listen for happy hour – the last blast on Race Day (May 13 for the Grand Prix), usually starting at 11 p.m. Indy time (0300 UTC). That’s when W9IMS ops traditionally switch to contest-style QSOs and exchange only signal reports so they can work as many stations as possible. But remember that W9IMS special events can end early if the station encounters sparse QSOs or adverse solar or weather conditions.

Should you manage to bag W9IMS, don’t celebrate for too long: The Indianapolis 500 special event begins on May 22, only 9 days after the end of Grand Prix week. Then comes the longer wait till the NASCAR race in August.

You’ll qualify for a new and unique QSL card for each W9IMS event you log, regardless of whether you snare all three in ’23. But why not complete the set and nab the certificate – starting with the first race this coming week?

Hams and SWLs alike are eligible for any and all W9IMS cards and certificates; you can even QSL via the bureau. And if you forgot to send in your information from a previous year, it’s still possible to obtain nearly all of the previous cards and certificates. Consult the W9IMS QRZ page for full details.

HAM – Official Documentary (YouTube)

Grazing the rich pastures of the interwebz I just stumbled upon this short documentary made by students of the School of Visual and Media Arts program at the University of Montana. It aired on Montana PBS in November 2022 and was uploaded to YouTube 2 weeks ago.

I like the modern style of this work, letting the images and the people in them speak for themselves, and radiate their fascination with the hobby. Enjoy!

Morse Code is making a comeback! Children as young as FIVE are learning the once groundbreaking form of communication – spurred on by K-Pop bands who use it to leak hints about upcoming songs to fans (Daily Mail)

Despite being created 180 years ago and not being a requirement for amateur radio operators to learn since 1990, it has been kept alive by radio enthusiasts – and now more young people are getting involved.

A combination of pandemic lockdowns forcing youngsters to learn something new, and the use of Morse Code by popular K-Pop bands, has led to ‘a renaissance’ in teens wanting to learn the once groundbreaking form of communication.

From five-year-olds to 99-year-old war veterans, people all over the world are tapping in to communicate with others on the radio. [Continue reading…]

Ham radio tunes in to a new generation (The Times)

As he sits in a shed on the outskirts of Cambridge, Martin Atherton twists a radio dial and picks up a message being sent in Morse code. The audio dots and dashes, familiar from black-and-white war films, might seem to be relics of a past era.

But more than a century after it was first used, this mode of communication appears to be making a comeback. Since 2006 the number of amateur radio licences, which allow holders to send Morse and voice messages, has increased by almost 60 per cent, according to the Radio Society of Great Britain.

Last year the number of 13 to 44-year-olds viewing the society’s online tutorials, which cover topics such as “improving your Morse skills” and how to build your own equipment, more than tripled.

Allowing people to reach out to distant lands on a shoestring budget, the hobby could have been tailor-made for lockdown. The Netflix series Stranger Things, in which a “ham” radio set is used to contact another dimension, has also been linked to an increase in interest.

“Teenagers are picking it up, so are retirees,” said Atherton, 69, a member of the Cambridge University Wireless Society. [Continue reading…]

Pirate Radio (Twenty Thousand Hertz – The stories behind the world’s most recognizable and interesting sounds.)

In the 1960s, the BBC had a vise grip on British radio, and rarely played the pop and rock music that was all the rage. So a group of rebellious radio DJs decided to give the people what they wanted, and started broadcasting popular music from boats stationed in international waters. Soon enough, these young DJs became national superstars… until the British government decided it was time to sink these pirates once and for all. This story comes from the History This Week podcast.

Radio Waves: Margaret Iaquinto’s Conversations with Cosmonauts, Why AM Stations Power Down at Night, PEI Ham Radio Surge, and Calls on Flights Allowed

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!


The unlikely story of an American ham radio amateur and her conversations with cosmonauts in space (PRI’s The World)

In the 1980s, Margaret Iaquinto was an amateur ham radio operator who communicated with Russian cosmonauts in space. She talked to them for over a year. Iaquinto died in 2014. But her son Ben Iaquinto remembers the friendships she developed with the cosmonauts. Marco Werman speaks to Ben Iaquinto about his mom’s hobby and the conversations she had with these Russian cosmonauts.

Radio Stations Shut Or Power Down At Night, Because Of The Laws Of Physics (IFL Science)

If you’re a radio fan, or have merely been stuck in a car as day transitions into night, you may have noticed that you don’t get quite as clear signal in the hours of darkness.

Before you assume that it’s a plot by reverse vampires (possibly in conjunction with the saucer people) in order to make radio listeners go to bed, you should know that it’s actually the result of a requirement by the Federal Communications Commission (FCC) to power down or turn off at night, and the FCC in turn are required to do this by the laws of physics.

It all has to do with wavelengths and the ionosphere. During the daytime, AM signals primarily propagate close to the ground (known as ground wave propagation) and follow the curves of the Earth. In the daylight hours, AM signals sent by radio stations can cover around 162 kilometers (100 miles) before you will struggle to hear the signal.

As good as this is, at night the ability of long waves to propagate large distances becomes a problem, thanks to the ionosphere. Between 80 and 600 kilometers (50-373 miles) above the Earth, particles in the Earth’s atmosphere are bombarded with Extreme Ultraviolet (EUV) and x-ray solar radiation, ionizing them as they do so. The ionosphere grows and shrinks (on your side of the planet) depending on the time of day.

At night, the layer reflects AM radio signals (known as “skywave” propagation) to a much greater degree than during the day, allowing the signal to be carried for hundreds of miles further than during the day. While this may sound like good news, it is what’s known as a “pain in the butt” for any communication regulators out there, or people who want to listen to anything other than an indiscernible mess of static.

“Because of this change in signal propagation from daytime to nighttime, if every AM station kept its daytime operating power at night, massive interference would result,” the FCC explains on their website. [Continue reading…]

Islanders’ interest in amateur radio surges because of COVID-19 and Fiona (CBC)

‘The sky’s the limit. There’s just so many different things that you can learn’

The amateur radio community on P.E.I. is growing, thanks in part to the COVID-19 pandemic and post-tropical storm Fiona.

Stratford resident Brent Taylor has been a ham radio operator for 38 years, in New Brunswick and P.E.I. He goes by the call sign VY2HF.

“It’s been absolutely fantastic. We have been so thrilled with the number of people that have come forward, and now that we’re getting them on the air,” Taylor said.

“Probably because of COVID, and maybe because of Fiona, there’s been a more of an interest, I think, in people wanting to be able to maintain their connections with each other, even from their own homes.”

Taylor said a dozen people started the 12-week training program in the fall, and eight passed their exams and are now licensed operators.

“The most diverse I’ve ever seen. And I’ve been teaching off and on this course for 35-plus years. To see the number of women in the course, for one thing, is just tremendous,” Taylor said.

“Also, cultural diversity and a wide range of ages from as young as 12 years old.” [Continue reading…]

No more airplane mode? EU to allow calls on flights (BBC)

Airline passengers in the European Union (EU) will soon be able to use their phones to full effect in the sky.

The European Commission ruled airlines can provide 5G technology on board planes, alongside slower mobile data.

This could mean flyers will no longer be required to put their phone on airplane mode – though the specifics of how it will be implemented are unclear.

The deadline for member states to make the 5G frequency bands available for planes is 30 June 2023.

This will mean people can use all their phone’s features mid-flight – enabling calls as well as data-heavy apps that stream music and video.

Thierry Breton, EU Commissioner for the Internal Market, said the plan would “enable innovative services for people” and help European companies grow.

“The sky is no longer a limit when it comes to possibilities offered by super-fast, high-capacity connectivity,” he said. [Continue reading…]
