W9IMS Special Event No. 1: The 2022 Certificate Chase Begins

By Brian D. Smith, W9IND

A journey of a thousand miles begins with a single step, as the proverb goes, and the road to a 2022 W9IMS Checkered Flag Award begins with a single QSO – or a single SWL reception.

W9IMS will stage special event stations commemorating each of the three major races at the Indianapolis Motor Speedway this year: the Grand Prix, the Indianapolis 500 and the NASCAR 200 at the Brickyard.

Your weeklong opportunity to complete the first of three required contacts with W9IMS starts Sunday, May 8, and ends at 11:59 p.m. Saturday, May 14 (0359 UTC Sunday, May 15). The special event schedule will resume only 8 days later with the Indy 500 operation (May 23-29), followed by the NASCAR 200 from July 25-31.

Individual QSL cards accompany each of the three events, and a Checkered Flag certificate awaits those who bag the trio. Hams and SWLs alike may apply for the cards and certificate; see www.w9ims.org for further information.

Where to find W9IMS? The station fires up on 20- and 40-meter General Class frequencies, usually on or near 14.245 and 7.245 MHz. But the easiest way to locate W9IMS is to check DX spots, especially on DX Summit at http://www.dxsummit.fi/

Type “W9IMS” in the search box at upper right and you’ll see which, if any, frequencies the station is currently occupying. Note that special event operations are not continuous throughout the week, but you’ll find scheduled times and operators on the W9IMS QRZ page – and there’s always the possibility of unscheduled appearances by operators with an hour or two to spare.

Any hour of the day or night is fair game, but the surest way to catch W9IMS is during prime time: weekdays from 6 to 10 p.m. Indy time or 2200 to 0200 UTC. And if all else fails, listen for happy hour – the last blast on Race Day (May 14 for the Grand Prix), usually starting at 11 p.m. Indy time or 0300 UTC. That’s when W9IMS ops traditionally switch to contest-style QSOs, exchanging only signal reports, to put as many stations in the log as possible.

Don’t stake your certificate on any announced schedule, however; W9IMS on-air times can be curtailed by adverse solar or weather conditions or a paucity of QSOs.

Likewise, the station has been known to activate an unannounced band, such as 80 meters, at the drop of a hat. Again, DX Summit and other DX spotting networks are your best friend in this regard.

Feel free to submit all of your 2022 QSL and certificate requests in the same envelope, and if you don’t have a QSL card, a printout of your W9IMS contacts or reception reports will suffice.

The Icom IC-705: Giuseppe’s pairs his new radio with his homebrew crossloop antenna

Leave a reply

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas,

I wanted to share my new purchase with all SWLing Post friends: the Icom IC-705.

It is truly a great portable QRP transceiver and a great receiver for broadcast listening.

In this video, shot on my balcony at home, is the first listening test on short waves. Crystal clear audio with cathedral effect. My portable cross loop antenna pairs very well with the IC-705.

It’s a simple video but it brings out all the listening potential of this 705.

Greetings to you and all the friends of our community.

73,

Giuseppe Morlè (IZ0GZW)

Thank you for sharing this, Giuseppe! I’ve found that the IC-705 has become one of my favorite portable receivers. It’s truly an amazing radio and, I believe, worth the hefty price tag. 

I published a very favorable review of this radio and 13DKA has as well. Also, check out Giuseppe Fisoni’s comparison of the IC-705 and IC-R8600. The IC-705 is a proper enthusiast-grade radio–I would purchase it just for the receiver functionality. Being a ham radio operator, I also take the IC-705 to the field very regularly–I post many of my field reports on QRPer.com. Recently, we’ve posted a number of articles about protecting the IC-705 during travels and in the field.

Thank you again for sharing this, Giuseppe!

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!

Study recommends revival of AMARC Africa (Red Tech)

HARARE, Zimbabwe — The unavailability of critical information about community radio in Africa has led the University of the Witwatersrand(Wits) journalism department and a consortium of media, civil rights and business NGOs — Fojo Media Institute, Civicus, Civil Rights Defenders, Defend Defenders and Hub Afrique — to carry out a study entitled “Mapping Community Radio in Sub-Saharan Africa.”

“Even basic information is hard to get, and it is often not even certain how many stations are on air. Operations collapse, and others start, with hardly anybody outside the immediate environment noticing. Even the licensing authorities sometimes struggle to keep accurate records,” revealed Prof. Franz Kruger, head of Wits Journalism.

Conducted by Jacob Ntshangase, the head of Wits Radio Academy, the study sought to gather information and better understand the community radio landscapes in different parts of Sub-Saharan Africa to identify needs, opportunities and potential partners for developing a program of support for community radio on the continent.

Can the HD Radio experience be of use in regional Australia. (RadioInfo)

The 2022 NAB Show is already underway in Las Vegas, and fresh from presenting some new research on HD radio in the US, Xperi SVP Broadcast Radio, Joe D’Angelo (pictured), sat down with radioinfo’s Wayne Stamm.

Joining the conversation was Commercial Radio Australia’s Head of Digital, Jamie Chaux, to add an Australian perspective and view on what might be gained from the HD experience in the States.

radioinfo: We’re talking about a couple of the presentations that are going to be made at NAB this year. Joe you’ve already done one of those presentations and taken a look at some very interesting studies that have been done recently about the penetration of HD radio, especially here in the US.

Joe D’Angelo: Yes, I finished a session today on actually UX guidelines (NABA Radio In-car User Experience) for in-car receiver design and that that went very well. And what’s really exciting about not only the work of the UX group, but the progress of HD radio, is we’re now at 85 million vehicles on the road.

And so we surveyed users of the technology and 91% of them came back and said that HD radio has significantly improved their radio listening experience.

74% of people said they would not buy another new car unless it had HD radio, which is very affirming.

Learning Electronics By Just Doing It (Southgate ARC via Hackaday)

Learning anything new, especially so broad and far reaching as electronics, can be hard. [IMSAI Guy] knows this because he gets asked regularly ‘how do I learn electronics?’ Many of you reading this will have a few ideas to pass along (and we encourage you to share your take on it in the comments below) but there is an even greater number of people who are asking the same question, and [IMSAI Guy]’s take on it is one that this particular Hackaday writer can relate to.

According to [IMSAI Guy], an excellent place to start is the ARRL Handbook. The ARRL Handbook is an electronics and RF engineering guide published by the Amateur Radio Relay League in the US. It’s a wonderful reference, and past editions can be had very inexpensively and are every bit as handy. Many hams will have a copy they could be talked out of, and you can likely find one at your local library. Where to start in the Handbook, then?

[IMSAI Guy] recommend starting with whatever catches your fancy. As an example, he starts with Op Amps, and rather than diving straight into the math of how they work or even worrying to much about what they are- he just builds a circuit and then plays with it to intrinsically understand how it works, a “learn by doing” approach that he has found extremely helpful just as many of us have. We also appreciated is very straightforward approach to the math: Don’t bother with it unless you need to for some reason, and definitely don’t start by learning it first.

Frans experiments with the MFJ-1026 Noise Canceling Signal Enhancer

23 Replies

Many thanks to SWLing Post contributor, Frans Goddijn, who writes:

“Last week I purchased the MFJ-1026 ‘noise canceling signal enhancer’ and I posted two blogs with video about it. Initially the device seemed as useless as it is good looking but then I found a configuration where the device is not only pleasant to have but also useful for radio listening.”

Here are Frans’ reports which he kindly shares from these two posts originally published on his blog, Kostverlorenvaart:

Part 1: MFJ-1026 deluxe noise canceling signal enhancer

Using a GRAHN antenna, (a VENHORST wire antenna for noise reference), the iCOM R8600 radio and optional bhi DSP audio noise canceling, trying to see what’s the best way to cancel noise — on the antenna entry point of the radio or at the speaker output end.

In this case the MFJ-1026 seems ineffective. The DSP at the audio output end works well and easy.

I have also tried two GRAHN antennas on the MFJ-1026, one for MAIN and one for AUX but that was also not noticeably effective yet.

I will also try the little whip antenna that MFJ supplied with the box. Further tweaking may turn out to be helpful on some other frequencies / signals.

Before installing the MFJ i used the little TECSUN H-501x to scan the room for any devices producing radio noise. It turned out that the two Apple Homepods sit in a dense cloud of radio noise, the Macbook Pro also radiates noise, EVE smart plugs controlling lights also produce radio noise, two little label printers s well and the HP printer/scanner too. So I moved those to the other end of the toom or to another room. Continue reading →

You and the ionosphere: Share your propagation stories!

Many thanks to SWLing Post contributor, Jock Elliott, who shares the following guest post:

You and the ionosphere . . . a reader participation post

By Jock Elliott, KB2GOM

Here’s a shocker for you: we live at the bottom of the sky. Above us there are multiple layers of the atmosphere, pressing down on us at 14.7 pounds per square inch.

Of particular relevance to us as shortwave listeners and hams, there is a special layer of the atmosphere, not shown on the chart above called the ionosphere. The ionosphere starts around 30 miles above us and extends up to about 600 miles and includes parts of the layers above.

The Sun’s upper atmosphere, the corona, is very hot and produces a constant stream of Ultra-Violet and X-rays, some of which reach our atmosphere.  When the high energy UV and X-rays strike the atmosphere, electrons are knocked loose from their parent atoms and molecules, creating a layer of electrons.

Now, here’s the cool part: this layer – the ionosphere – is important because radio waves bounce off of it.

The sun, however, is not constant in its action on the ionosphere. The amount of UV and x-ray energy (photon flux) produced by the sun varies at by nearly a factor of ten as the sun goes through an 11 year cycle. The density of the ionosphere changes accordingly, and so does the ability of the ionosphere to bounce radio waves. When the sun is at peak activity, and the ionosphere is “hot,” SWLs and hams are likely to experience excellent long-range propagation. When the sun is quieter, long-range propagation diminishes.

Every 11-year solar cycle is unique, but early indications are that we may on the verge a cycle that favors long-range propagation: https://swling.com/blog/2022/03/termination-event-may-indicate-solar-cycle-strength/

The results can be spectacular. Decades ago, during a particularly hot solar cycle, I once spoke from my station near Albany, NY, to a station in the state of Georgia on a mere 4 watts. On another occasion, I conversed with a ham in Christchurch, New Zealand – a distance of over 9,000 miles – with 100 watts single sideband transmit power. During that same period, I would routinely listen to shortwave stations halfway around the world.

And now, it’s your turn – what’s your favorite long-range propagation story, either as an SWL or ham? Please comment!

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Good news for Pacific regional broadcasting – bad news for locals (Asia Pacific Report)

Good news — an Australian parliamentary review recommends a more “expansive” media presence in the Pacific.

Bad news — little of that expansion envisions a role for island media.

Instead, the committee endorsed a proposal for “consultation” and the establishment of an independent “platform neutral” media corporation, versus the existing “broadcasting” organisation.

That proposal was among several points raised at two public hearings and nine written submissions as part of Australia’s “Pacific Step Up” programme, aimed at countering the growing regional influence of China.

Former long-time Pacific correspondent Sean Dorney last month told the Joint Standing Committee on Foreign Affairs, Defence and Trade that Australia was previously leading regional media spaces.

“But the vacant space that was left there when Australia Network disappeared, as people have said, has really been taken over by China,” he said.

“Throughout my time as the Pacific correspondent for the ABC, I saw this Chinese influence growing everywhere.”

[…]Taking up ten of 176 pages, the report’s media section is nonetheless seen as relatively comprehensive compared with the dismantling of broadcasting capacity in recent years.

This includes the literal dismantling of shortwave equipment in Australia despite wide protest from the Pacific region.

Nearly three years previously, a 2019 Pacific Media Summit heard that discontinuation of the shortwave service would save Australia some $2.8 million in power costs.

A suggestion from a delegate that that amount could be spent on $100,000 for reporters in each of 26 island states and territories was met with silence from ABC representatives at the summit.

However, funding would be dramatically expanded if the government takes up suggestions from the submissions to the joint committee. [Continue reading the full article…]

Pay Your Respects To Radio, The Ancestor Of Podcasting (Rolling Stone)

In the 1890s, Italian inventor Guglielmo Marconi left a lasting legacy when he sent a wireless telegraph message via Morse Code to a recipient. By the turn of the 1900s, Marconi’s innovation would give rise to an entirely new industry, one focused on creating new ways for people to communicate even across vast distances: radio.

Throughout the first half of the 20th century, radio would not only play a major role in the international correspondence of countries fighting in both World Wars but it also became a widely popular phenomenon amongst the general public. By the mid-1920s, there were hundreds of licensed radio stations hosting news broadcasts, comedy shows, dramas, live music, sports programs and other forms of entertainment.

A century later, it’s not hard to spot the parallels between what made radio one of the most popular content mediums in history and the explosive growth of radio’s evolution in podcasting. Though there are some unique differences between the two mediums, I believe podcasters should still pay respect to how the evolution of radio gave rise to the advent of podcasting.

The Rise of Contemporary Audio Entertainment
On October 30, 1938 — the evening before Halloween — Orsen Welles hosted a radio adaptation of H.G. Wells’s science fiction novel, The War of the Worlds, “converting the 40-year-old novel into fake news bulletins describing a Martian invasion of New Jersey.” While Welles and his team reportedly had no intention to deceive listeners into believing the broadcast was in any way real, Welles would later go on to say in a 1960 court disposition about his desire to release the broadcast, “in such a manner that a crisis would actually seem to be happening…and would be broadcast in such a dramatized form as to appear to be a real event taking place at that time, rather than a mere radio play.” [Continue reading at Rolling Stone…]

Why Russian radios in Ukraine are getting spammed with heavy metal (The Economist)

Ukrainians are eavesdropping on the invaders and broadcasting on their frequencies

One of the many surprising failures of the Russian invasion force in Ukraine has been in radio communications. There have been stories of troops resorting to commercial walkie-talkies and Ukrainians intercepting their frequencies. This may not sound as serious as a lack of modern tanks or missiles, but it helps explain why Russian forces seem poorly co-ordinated, are falling victim to ambushes and have lost so many troops, reportedly including seven generals. What is going wrong with Russian radios? Continue reading →

Ukraine war: BBC World Service granted extra funding (BBC News)

The BBC World Service will receive more than £4m in extra funding from the UK government to help counter disinformation about the Ukraine war.

The BBC made the request for the money, which will also be used by the Ukrainian and Russian language services to cover urgent and unexpected costs.

It welcomed the announcement and said the money would help relocate staff and operations to safe locations.

The two language services have had record audiences since the invasion.

The announcement on Wednesday followed a BBC request to the Department for Digital, Culture, Media and Sport and the Foreign Office.

“The BBC has seen a big demand for clear, fact-based, impartial journalism to counter disinformation and our teams are working around the clock to bring people the very best independent journalism,” BBC director general Tim Davie said.

“This funding will also help us with the immediate need to support staff who have been displaced, many of whom are continuing to work and provide vital expertise to the whole of the BBC,” he added. [Continue reading…]

BBC gets emergency funding to fight Russian disinformation (Gov.UK)

£4.1 million in additional funding for BBC World Service to support Ukrainian and Russian language services in the region

The government is giving the BBC World Service emergency funding to help it continue bringing independent, impartial and accurate news to people in Ukraine and Russia in the face of increased propaganda from the Russian state.

BBC World Service will receive an additional £4.1 million in emergency funding to support its Ukrainian and Russian language services in the region, and to help it increase trusted and independent content to counter disinformation about the war in Ukraine.

BBC World Service channels – including TV, radio and digital – play an increasingly valuable role in challenging the Kremlin’s disinformation, but it is facing additional costs from operating within a military conflict and due to a crackdown on independent reporting in Russia.

Following a BBC request, the Department for Digital, Culture, Media and Sport and Foreign, Commonwealth and Development Office will provide the extra funding to cover urgent and unexpected costs that have arisen as a result of the conflict.

This will help the BBC to relocate staff and operations to safe locations to ensure the resilience of their services and that they continue to reach people in Russia and Ukraine.

The BBC will also use the funding to continue expanding new and more widely accessible content, delivered through a range of channels, to tackle disinformation and to help local audiences circumvent the Kremlin’s media restrictions and continue to access the BBC’s journalism.

Culture Secretary Nadine Dorries said:

The Government is providing the BBC with an additional £4.1 million in emergency funding to help the World Service broadcast directly into Ukraine and Russia.

In scenes reminiscent of 80 years ago, the BBC will ensure that audiences in the region can continue to access independent news reporting in the face of systemic propaganda from a dictator waging war on European soil. It’s vital we lift the veil on and expose the barbaric actions of Putin’s forces.

Minister for Europe and North America, James Cleverly said:

Britain is calling out Putin’s lies and exposing his propaganda and fake news.

This new funding will help strengthen the BBC’s impartial voice in Russia and Ukraine, which is critical to counter Russian disinformation and will help ensure we win the battle for the airwaves.

ENDS

Notes to Editors

The World Service receives funding from the BBC’s licence fee income, in addition to grant funding directly from the FCDO. The World Service’s Spending Review settlement for the period 2022 to 2025 from the FCDO will be confirmed shortly.

The Culture Secretary made it clear to the BBC in her letter confirming the final licence fee settlement that the BBC should continue to make a substantive investment from the licence fee into the World Service to ensure that it continues to effectively reflect the United Kingdom, its culture and values to the world – in English and through its language services.

Russia, Ukraine Get News From Shortwave Radio Station In South FL (Patch)

Radio Miami International (WRMI)? is working with Shortwaves for Freedom to transmit news to Russia and Ukraine during the war.

OKEECHOBEE, FL — When the commercial shortwave radio station Radio Miami International — which operates under the call letters WRMI — got its start in 1989, its primary focus was helping Cuban exile groups in Miami legally transmit programming to their homeland.

Since then, the station has broadcast news during all sorts of trying times — the Gulf War, hurricanes, earthquakes, other natural disasters.

Now, 30 years later, at a time when Instagram, TikTok and other social media platforms rule when it comes to communication, WRMI finds itself in a unique position during Russia’s invasion of Ukraine. Working with several organizations and government groups, the station is broadcasting news programming to both Russians and Ukrainians who have access to shortwave radios.

“We’ve been through all sorts of crises. This is one of the biggest,” said Jeff White, the station’s general manager.

When the station launched three decades ago, Radio Miami International worked with Cuban exiles and Latin American groups to find existing shortwave stations where they could buy airtime to broadcast shows. [Continue reading…]
