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!

Many thanks to SWLing Post contributors Dennis Dura, Ron Chester, and Mangosman for the following tips:

Ham Radio Verbindung 2021 kommt nicht zustande/Ham Radio convention 2021 has been cancelled (Messe Friedrichshafen)

[Note that the following is a Google translation of the original piece in German]

Ham Radio cannot take place this year either – other trade fair events remain on course

Due to the current corona developments, Messe Friedrichshafen cannot hold the international amateur radio exhibition Ham Radio in the planned period from June 25 to 27, 2021. Instead, the industry meeting will take place from June 24 to 26, 2022.

“The decision was not an easy one for us, but a trade fair like Ham Radio lives from its high level of internationality. Due to the current uncertainties in the travel sector, implementation is currently not feasible, ”explains Klaus Wellmann, Managing Director of Messe Friedrichshafen. All other trade fair events in the second quarter of 2021 and beyond should take place as planned at the present time. “A large percentage of our customers from these industries are still on board at the 2021 events. Together we hope that the immunization of society continues to gain momentum and that we can carry out the events with appropriate protection and hygiene concepts. “

Rare Diode Threatens Coast Guard’s Arctic Ambitions (Hackaday)

The United States Coast Guard heavy icebreaker Polar Star is literally a one-of-a-kind ship. After its sister Polar Sea was deactivated in 2010 it became the most powerful icebreaker in the fleet, and one of only two US icebreakers capable of operating in the treacherous polar regions. The vessel is critical to protecting America’s scientific and economic interests in the Arctic, but according to a recent article in Business Insider, the ship’s age and scarcity of spare parts is making an already difficult mission even harder.

In the article, Captain William Woityra specifically mentions that the ship’s diesel-electric propulsion system is running on borrowed time as the diodes used in its AC/DC rectifier are no longer manufactured. With none remaining in the Coast Guard’s inventory, the crew has had to turn to eBay to source as many spares as possible. But once their hoard runs out, Captain Woityra fears his ship will be dead in the water[…]

A toast to the fools standing high on broadcasting’s hill (Doc Searls Weblog)

In Winter, the cap of dark on half the Earth is cocked to the north. So, as the planet spins, places farther north get more night in the winter. In McGrath, Alaska, at close to sixty-three degrees north, most of the day is dark. This would be discouraging to most people, but to Paul B. Walker it’s a blessing. Because Paul is a DXer.

In the radio world, DX stands for for distance, and DXing is listening to distant radio stations. Thanks to that darkness, Paul listens to AM stations of all sizes, from Turkey to Tennessee, Thailand to Norway. And last night, New Zealand. Specifically, NewsTalk ZB‘s main AM signal at 1035 on the AM (what used to be the) dial. According to distancecalculator.net, the signal traveled 11886.34 km, or 7385.83 miles, across the face of the earth. In fact it flew much farther, since the signal needed to bounce up and down off the E layer of the ionosphere and the surface of the ocean multiple times between Wellington and McGrath. While that distance is no big deal on shortwave (which bounces off a higher layer) and no deal at all on the Internet (where we are all zero distance apart), for a DXer that’s like hauling in a fish the size of a boat.

In this sense alone, Paul and I are kindred souls. As a boy and a young man, I was a devout DXer too. I logged thousands of AM and FM stations, from my homes in New Jersey and North Carolina. (Here is a collection of QSL cards I got from stations to which I reported reception, in 1963, when I was a sophomore in high school.) More importantly, learning about all these distant stations sparked my interest in geography, electronics, geology, weather, astronomy, history and other adjacent fields. By the time I was a teen, I could draw all the states of the country, freehand, and name their capitals too. And that was on top of knowing on sight the likely purpose of every broadcast tower and antenna I saw.[…]

DRM Makes Its Pitch for India’s FM Band (Radio World)

In India, where regulators have been working toward recommending a standard to digitize the FM band, Digital Radio Mondiale is presenting its case.

DRM has been conducting trials and demos since late February, when a digital radio transmission with three audio services and Journaline text information went live in Delhi alongside existing analog FM transmissions.

It said it is also showing the possibility of extending a shared transmitter infrastructure by broadcasting up to six individual DRM signals or blocks, carrying up to 18 audio services plus 6 multimedia services, being broadcast from one FM transmitter and antenna. It said the number of individual DRM signals is only limited by the bandwidth of the transmitter. Each signal can have its own power level, and gaps in the spectrum are possible, as are individual SFN networks per DRM signal.

“The transmission is part of an extensive trial and demonstration of DRM conducted by Prasar Bharati and its radio arm, All India Radio (AIR), with the help of the DRM Consortium and its local and international members,” DRM stated in a press release. “The test was officially launched on Feb. 24 and 25 at the headquarters of All India Radio in New Delhi.”

The test was requested by regulator TRAI and the Ministry of Information & Broadcasting.

DRM officials said a presentation to AIR’s committee showed DRM in the FM band on various car radios including line-fit, aftermarket, standalone receivers, mobile phones and tablets. A head unit from Mobis, upgraded for FM via firmware, was installed in a Hyundai Verna. DRM said, “The reception was found to be excellent for over 15 km radius with just 100 W of DRM power in digital,” including 5.1 surround sound test broadcasts on DRM.[…]

Nick acquires a Harris RF 505A receiver

Many thanks to SWLing Post contributor, Nick Booras, who writes:

I just picked up a Harris 505A and I made a couple videos your viewers might like.

This radio is extremely sensitive as you can see in the comparison videos. I am very lucky to have picked it up. I will add that in the comparison to the Kenwood TS890 I didn’t try the 15 kHz filter on video. I did try it afterwards and I was surprised to receive the weak 6.085 signal with similar results to the 505. I thought for sure that that huge width would only let in more noise but I was wrong. I learned something new! But the 505A is still a super sweet machine.

Thank you for sharing this, Nick! What a wonderful addition to your radio collection. I’ve always loved the incredibly simple design of the 505A and have assumed it would have a very low noise floor.

Thanks again!

Dan notes a spike in Zenith Trans-Oceanic prices

Many thanks to SWLing Post contributor, Dan Robinson, who notes:

There appears to be a spike in Zenith Trans-Oceanic sales. The recent eBay sale of a D7000Y for $900 sparked a number of new auctions by sellers seeking to take advantage of this apparent
trend.

The following D7000Y was listed with a $900 Buy It Now price by someone obviously
cashed in.

Wow! I’m curious what could have encouraged this spike in prices. I have a Trans-Oceanic but will not sell it because it was my first portable radio. With that said, if there are readers who’ve considered parting with theirs, this might be the right time. Thanks for the tip, Dan!

RIP George Zeller: Losing a giant in our shortwave radio world

Many of us who were friends with George Zeller or who regularly attend the Winter SWL Fest are devastated to learn that this well-loved SWL personality passed away after an unintentional electrical fire in his Cleveland home on Saturday March 20, 2021.

Richard D’Angelo with NASWA posted this message about George:

I was shocked and saddened to learn of George Zeller’s sudden passing earlier today (March 20) in a house fire this morning. I had exchanged emails with George earlier this week on NASWA editorial matters as he was slowly recovering from his recent Covid-19 vaccination. The news article in the online Cleveland Comeback mentioned overcrowded electrical outlets/extension cords as the cause of the accidental fire. George was 71 years old.

George and I knew each other for about 40 years. George came to several DXpeditions at Gifford Pinchot and French Creek State Parks. We attended many of the same radio hobby gatherings over the years. For several years, I traveled to Cleveland for work; George and I would go out to dinner on those occasions. Naturally, any time my company was mentioned in the local newspaper George would eagerly forward that information to me. George also traveled to the Winter SWL Festival in Plymouth Meeting, Pennsylvania each year to gather with like minded radio people. He attended other radio conventions too over the year’s throughout the country.

George was well known in the greater Cleveland area as an Economist who kept close tabs on the Ohio economy. The Economic Indicators project he worked on provided continually updated information on poverty, earnings, and the economy in all Ohio counties and communities, with related demographics. In Ohio, Economic Indicators data include annual income trends for all 612 Ohio school districts. Detailed data was also available for job growth and payroll earnings in all Ohio counties going back to 1979, including measures of the very large job losses suffered by Cleveland and Ohio during the 2000s recession that has lingered longer in Ohio than it did elsewhere in the United States. Over the year’s he mixed with local political figures and served as a volunteer in a number of community organizations serving the greater Cleveland area. He was a regular on several talk radio programs when Ohio’s economy was the lead topic.

George was an active baseball and football fan. He attended baseball games wherever he could. He spent time traveling to difference cities attending games in many major league and minor league baseball stadiums. I recall making such a trip to Camden Yards in Baltimore with several others to catch an Orioles-Yankees baseball game when my children were youngsters. He was an enthusiastic Cleveland Indians and Cleveland Browns fan going back to the glory days of the 1950’s. He never forgave the Indians for trading away Rocky Colavito.

For twenty years George wrote a column about unlicensed pirate and clandestine shortwave radio broadcasting news in Monitoring Times magazine. He was also a contributing editor to Passport to World Band Radio, the definitive guide to international shortwave broadcasting frequencies, schedules, and receiving equipment. For decades he wrote a column on Clandestine radio broadcasting in the monthly issues of The ACE from the Association of Clandestine Radio Enthusiasts. Annually, he hosted the Pirate Radio Forum at the Winter SWL Festival in Plymouth Meeting, Pennsylvania as well as being the host of the prize raffle at the Saturday night banquet. In recent years, George was the editor of the Pirate Radio Report column for the North American Shortwave Association. He joined NASWA in December 1965 as a lad of sixteen.

George was always fun to be with and a real character to boot. No matter what the topic of the conversation was, he had a story that may or may not have been pertinent. There was never a dull moment when he was part of the group. George Zeller will be missed by all of us.

Thank you for sharing, Rich.

In the news article about the house fire, his neighbor described George as always kind and somewhat reclusive. With his radio community, he was everything but reclusive.

George had a huge personality, amazing sense of humor, and perhaps what I admired about him most was his ability to poke fun of himself. A quality I hold in high regard.

We will miss you, George.

Social DXing: Looking back at one very radio-active year

17 Replies

One year ago, I posted an article about making the most of social distancing as the world started locking down due to the rapid spread of Covid-19. Here in March 2021, the news is looking much better: vaccines are being distributed at a record pace across the globe and number of cases and deaths are mostly on the decline.

Looking back

As I look back at the Social DX Bucket List I made last year, I’m happy to see that I actually accomplished about 64% of the goals I listed. I knew some of those goals would take well over a year to achieve (the QRP EME one especially).

In particular, I’m chuffed that I braved up and started doing Parks On the Air (POTA) and Summits On The Air (SOTA) activations in CW (Morse Code). That was a huge step for me and I’ll freely admit: I was nervous about it. But in July 2020, I managed to do my first CW activation and since then it has become my choice mode of operating in the field. CW is such a simple mode and so efficient–plus it gives me a sense of connection with the roots of radio communications.

I also accomplished a few things I never set out to do:

Not a typical radio year for me

In a “normal” year, I do way more SWLing than I do ham radio activity.

Last year, I started doing caregiving for my parents in my hometown–I’m typically there 2-3 days a week. While I’ve done shortwave listening and even a little MW DXing in my hometown, I typically don’t have a lot of time, especially in the evening hours. I just want to hit the sack early. QRM is also debilitating there and while I’d like to install a permanent Loop On Ground antenna to mitigate the noise (you heard that right, Andrea!) I’m not entirely sure I’d even have the dedicated listening time to justify it. When I’m there, I like to spend quality time with my folks.

In general, I’ve had much less free time. Indeed, if you’ve written to me via email, you’ll know this based on how long it’s taken me to reply. It can take several weeks especially if the reply requires a detailed response (which many do).

En route to, and on the way back from my hometown, I’ve found that doing park and summit activations has been very rewarding. Last year, I believe I completed a total of 82 park activations.

POTA has given me an excuse to explore public lands I’ve never visited before. Plus, I love nothing more than taking radios to the field–both receivers and transceivers.

Hamming and SWLing

At the end of the day, I’m an SWL and a ham radio operator. I find the two activities complimentary.

Side note: As I mentioned in my Winter SWL Fest presentation this year, it saddens me when I receive angry emails from readers after I post items that are ham radio related. We’ve upwards of 7,000-10,000 daily readers on the SWLing Post and the number of complaints are a teeny, tiny fraction of our readership. I only receive messages like this about once a month and they typically say something akin to “I don’t like the ham radio stuff, so if you don’t stop posting it, I’m leaving!” (FYI: That’s a real quote taken from the last one I received in January). I can only assume that at some point in the past, a ham radio operator has been a jerk to this and other radio enthusiasts. It’s a shame, too. I hate seeing the negative impact of one loud troll compared with the encouragement and support of much better people. All of my ham radio friends are not only supportive of SWLing, but almost all got their start in radio via the shortwaves. I’m certainly a case in point.

I love all things radio and I believe the SWLing Post is a reflection of that. If it offends you, then it might make sense to surf somewhere else.

Now where was I? Oh yeah…

POTA and SOTA outings have helped to satisfy some of my travel cravings as well. I miss going to radio conventions, hamfests, and especially traveling internationally with my family. We are a family who love national parks, forests, and other wildlife areas. Having an excuse to explore public lands we haven’t visited before has been amazing fun.

After POTA activations, I’ll often do a little SWLing since I already have an external antenna up and it’s typically connected to a good general coverage transceiver in a spot with zero RFI or QRM. I’ve especially enjoyed my DXing sessions with the superb Icom IC-705.

Listening habits

One indicator that I did less radio listening last year was the low number of recordings I made. I checked my audio folder recently and saw that I only made a couple dozen recordings–most were staple broadcasters, not rare or special DX.

At the end of the day, I realize that when I do SWLing sessions I like to have dedicated time–at least an hour or two–with headphones on, losing myself on the radio dial.  I simply haven’t had many opportunities this past year to make that a reality.

That’s okay, though. The great thing about the shortwaves is that they’re always there, patiently waiting for us to dive back in!

Looking forward

I’m really not sure what’s in store for me this year, but I know it’ll involve a lot of radio time and that pleases me to no end. I’ve made a few fun goals, but my hope is that, by the end of the year, I may even be able to do some proper travel–maybe even take a flight!

I do know this: I have an even more profound appreciation for my radio enthusiasm as I realize it’s the perfect space to travel and explore the world no matter how “locked down” things are. Based on feedback from readers and contributors to this site, I know I’m not the only one who feels this way.

How about you?

Did your radio activity change or pivot this past year? Did you have more or less time to hit the airwaves? Please comment!
