Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Recently, I’ve received a number of emails from readers who are frustrated because new ham radio transceivers are out of stock and used prices have increased.
At first, I thought this might be due to supply chain and logistics issues due to the continuing Covid-19 pandemic. If it is, it’s only a partial explanation.
As of this morning, I’ve heard from three trusted sources in the radio industry (from retailing and manufacturing) who tell me that the lack of inventory is a supply chain issue, but directly linked to the October 21, 2020 fire at Asahi Kasei Microsystems (AKM) Nobuoka semiconductor Plant “Fab2”.
“This factory mainly produces large-scale integrated circuits (LSI) used in audio equipment, home appliances, TCXO oscillator, and other products. Due to the recent fire, AKM has been forced to stop production and delays are to be expected.”
Fortunately, according to the article, AKM has been moving some IC production to external companies, but it could take some time to re-tool. A number of markets have been affected by this disruption including the pro audio industry.
There’s no need to panic
If you’ve been looking for a specific radio model, you may find that retailers have been back-ordered and can only offer a vague shipping timeline; 2-6 weeks out, for example.
Some models (including the popular IC-7300, IC-705, Yaesu FT-DX10, and Yaesu FT-991A) are still in-stock at some retailers.
Several readers have been trying to purchase the popular Yaesu FT-891 and found that no one has inventory at present. We may be looking at extended delays for this model and others once inventory is depleted.
But again, I don’t think this is a panic situation. This supply chain disruption has been in play for a number of months already and you can bet the industry is already working on solutions.
My advice would be that if you’re getting close to pulling the trigger on a new transceiver, if it’s in stock, I’d jump on it now. Otherwise, you’ll simply need to be patient as new inventory eventually makes its way back to retailer shelves. Used prices on some of these models may be inflated until new inventory returns.

I am stuck in the house in Texas, bored and with no power. So I decided to make a couple videos with my phone. One nice thing about a power outage… no RFI [Radio Frequency Interference].
This Icom 705 is an awesome radio! Perhaps your viewers might like these.

Thank you for sharing these, Nick! Yes, as we’ve noted before, power outages are an ideal time to play radio and indulge in a low-noise environment! And I agree with you: the IC-705 is a superb shortwave broadcast receiver.
I hope our readers in Texas will have power restored soon–this has been a rough week for many.

Thomas,
I got a new FT-891 recently and wanted a protective case for taking it out into the field.
A mixture of internet searches and Amazon algorithms turned up this very affordable case which closely matches the size of the radio, as the enclosed photograph shows.
It uses the familiar pick and pluck foam, although in two layers.
The base layer is a bit thin, so I might put a layer of rigid plastic over it to stop the feet of the radio pushing down to the outer case.
I prioritised the side wall thickness opposite from the carry handle, as the case is designed to sit on its side like a briefcase.
Wow, Mark! I do love the size of this case and the fact that it fits the FT-891 so perfectly.
Recently, I’ve been thinking about building out a case to hold one of my smaller QRP transceivers (the KX1, KX2, or MTR3B) in the field to be used when it’s raining. Perhaps this has been on my mind because I’ve been enjoying nearly 5 straight days of rain and fog! A case like this would be an affordable solution and I wouldn’t feel terribly bad about drilling through the case to mount antenna, key, mic, and headphone ports.
I, for one, would love your thoughts about the Yaesu FT-891 as well. I’ve contemplated reviewing it this year mainly because so many field operators rave about it. I’d be curious what you think about it in terms of shortwave radio listening.
Thank you again for the tip!

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’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!
Many thanks to SWLing Post contributors Eric McFadden, Mike Terry, for the following tips:
A new study in the research journal Space Weather considers what might happen if a worst-case coronal mass ejection (CME) hit Earth — a “perfect solar storm,” if you will.
In 2014, Bruce Tsurutani of Jet Propulsion Laboratory (JPL) and Gurbax Lakhina of the Indian Institute of Geomagnetism introduced the “perfect CME.” It could create a magnetic storm with intensity up to the saturation limit, a value greater than the Carrington Event of 1859, the researchers said. Many other spaceweather effects would not be limited by saturation effects, however. The interplanetary shock would arrive at Earth within about 12 hours, the shock impingement onto the magnetosphere would create a sudden impulse of around 234 nanoteslas (nT), and the magnetic pulse duration in the magnetosphere would be about 22 seconds. Orbiting satellites would be exposed to “extreme levels of flare and interplanetary CME (ICME) shock-accelerated particle radiation,” they said. The event would follow an initial CME that would “clear the path in front of it, allowing the storm cloud to hit Earth with maximum force.”
The Solar and Heliospheric Observatory (SOHO) has observed CMEs leaving the sun at speeds of up to 3,000 kilometers per second, and many instances of one CME clearing the way for another have been recorded.
The CME’s 12-hour travel time would allow little margin for preparation. The CME would hit Earth’s magnetosphere at 45 times the local speed of sound, and the resulting geomagnetic storm could be as much as twice as strong as the Carrington Event. Power grids, GPS, and other services could experience significant outages.
More recent research led by physicist Dan Welling of the University of Texas at Arlington took a fresh look at Tsurutani and Lakhina’s “perfect CME,” and given improvements in spaceweather modeling, he was able to reach new conclusions.
Welling’s team found that geomagnetic disturbances in response to a perfect CME could be 10 times stronger than Tsurutani and Lakhina had calculated, especially at latitudes above 45 to 50 °. “[Our results] exceed values observed during many past extreme events, including the March 1989 storm that brought down the Hydro-Québec power grid in eastern Canada, the May 1921 railroad storm, and the Carrington Event itself,” Welling summarized.
A key result of the new study is how the CME would distort and compress Earth’s magnetosphere. The strike would push the magnetopause down until it’s only 2 Earth-radii above Earth’s surface. Satellites in Earth orbit would suddenly find themselves exposed to a hail of energetic, and potentially damaging, charged particles.
Other research has indicated that phenomena such as the Carrington Event may not be as rare as once thought. A much weaker magnetic storm brought down the Canadian Hydro?Québec system in 1989.
Scientists believe a perfect CME will happen someday. As Welling et al conclude, “Further exploring and preparing for such extreme activity is important to mitigate spaceweather-related catastrophes.”
In July 2012, NASA and European spacecraft watched an extreme solar storm erupt from the sun and narrowly miss Earth. “If it had hit, we would still be picking up the pieces,” said Daniel Baker of the University of Colorado at a NOAA Space Weather Workshop 2 years later. “It might have been stronger than the Carrington Event itself.”
The FCC has announced that on July 27th an auction will be held for 136 FM construction permits and 4 AM’s. In this auction, the 130 FM permits that were previously included in the March 2020 auction, that had to be canceled due to COVID, will be included plus an additional 6 permits. Anyone who applied for stations in the planned 2020 auction must reapply. All applications for the previous auction have been dismissed.
[…]You can see the FM stations to be auctioned off HERE.
The Commission is proposing a simultaneous multiple-round auction format. This type of auction offers every construction permit for bid at the same time and consists of successive bidding rounds in which qualified bidders may place bids on individual construction permits. Typically, bidding remains open on all construction permits until bidding stops on every construction permit.
A number of months ago I was scanning around the AM dial late in the evening from my Portland, Oregon abode. I stumbled upon a station playing hard rock, which I thought to be an unusual find. As the AM dial has become mostly the domain of conservative and sports talk, I rarely encounter music that isn’t a bumper or part of some leased-time foreign-language programming.
In fact, at first I thought perhaps the music was a lead-in to just another talk show, but eventually I heard a full set of three songs. The station identified itself as “The Bear,” but curiously gave an FM frequency, not one on the AM dial.
An internet search the next day confirmed that “the Bear” is indeed an active rock formatted station located in Merced, California. Its logo features 105.7 FM prominently, with the 1660 AM frequency tucked in the corner. Yet, the AM signal is actually the primary one – the FM is a 250 watt repeater (translator) station.
Here’s a quick aircheck of the Bear’s station ID, during a break in the syndicated hard rock “Loudwire” program.
Now, AM stations have been permitted to get FM translators for a few years now as part of the FCC’s so-called “AM revitalization” initiative. But mostly I’ve heard sports and news/talk stations get repeated on FM.
I filed away this experience in memory, but kind of considered it a one-off. That was until my recent vacation in the Wallowa Mountains of Northeastern Oregon. Stowed away and social distancing in a mountainside cabin with limited internet and no cable, I spent quite a bit of time scanning the AM and shortwave bands in search of interesting sounds.

If you’ve thought about attending the annual Winter SWL Fest, but found it difficult to make the travel arrangements, this year you can get a taste of the Fest by attending virtually.
Many thanks to SWLing Post contributor, John (VA1JG), who notes:
As per the following exchange on the Yaesu Facebook group, the FTDX3000 is the latest Yaesu HF model to be discontinued:
John Kruk is the national sales manager for Yaesu USA, so this is real news. This was posted on Tuesday.
Many thanks for the tip, John! I’ve noticed a number of retailers have listed it as discontinued. If memory serves, I believe this FT-DX3000 was first introduced at the 2012 Hamvention, so it has had a decent market run. No doubt, the new FT-DX10 will be Yaesu’s focus in this price bracket.
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’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.
Army researchers built the quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to 20 GHz—and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.
The Rydberg sensor uses laser beams to create highly-excited Rydberg atoms directly above a microwave circuit, to boost and hone in on the portion of the spectrum being measured. The Rydberg atoms are sensitive to the circuit’s voltage, enabling the device to be used as a sensitive probe for the wide range of signals in the RF spectrum.
“All previous demonstrations of Rydberg atomic sensors have only been able to sense small and specific regions of the RF spectrum, but our sensor now operates continuously over a wide frequency range for the first time,” said Dr. Kevin Cox, a researcher at the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory. “This is a really important step toward proving that quantum sensors can provide a new, and dominant, set of capabilities for our Soldiers, who are operating in an increasingly complex electro-magnetic battlespace.”
The Rydberg spectrum analyzer has the potential to surpass fundamental limitations of traditional electronics in sensitivity, bandwidth and frequency range. Because of this, the lab’s Rydberg spectrum analyzer and other quantum sensors have the potential to unlock a new frontier of Army sensors for spectrum awareness, electronic warfare, sensing and communications—part of the Army’s modernization strategy.
“Devices that are based on quantum constituents are one of the Army’s top priorities to enable technical surprise in the competitive future battlespace,” said Army researcher Dr. David Meyer. “Quantum sensors in general, including the one demonstrated here, offer unparalleled sensitivity and accuracy to detect a wide range of mission-critical signals.”
The peer-reviewed journal Physical Review Applied published the researchers’ findings, Waveguide-coupled Rydberg spectrum analyzer from 0 to 20 GigaHerz, co-authored by Army researchers Drs. David Meyer, Paul Kunz, and Kevin Cox[…]
Six to eight decades ago polio was one of the most feared diseases in the US. In 1952 alone, 60,000 children were infected, 3000 died and many more were paralyzed.
The most severe outbreaks were in 1937 and 1946. My father was a victim of the 1946 epidemic, suffering minor paralysis in one leg as a child.
In 1937, many schools around the country closed, as did public pools, movie theaters and parks. But the Chicago public school system took an innovative approach.
During that period, 80% of US households contained a radio. This allowed 325,000 children in grades 3-8 to continue their education at home via radio lessons aired by six Chicago radio stations (WENR, WLS, WIND, WJJD, WCFL, WGN) that donated time for the purpose.
Program schedules for each day were printed in the morning paper. Home with more than one radio & more than one child often set up radios in different rooms so that each child could hear the appropriate grade’s lesson.
This continued for one month…until schools reopened in late September of that year.
Curriculum was developed by teachers and monitored over the air by school officials. After each episode, a limited number of teachers were available for phone calls. A large number of the calls were from parents distressed that they could not clearly receive the broadcasts.[Continue reading…]
BBC Woofferton Early Days (Ludlow Heritage News) [PDF]
Very few structures are left in the Ludlow area which can be traced back to the Second World War. However, look five miles south of the town towards the rise of the hills and a tracery of masts can be seen. Go closer, and a large building can be found by the road to Orleton, surrounded now by a flock of satellite dishes, pointing upwards. The dishes are a sign of the recent past, but the large low building was made for the war-time radio station aimed at Germany.
This little history attempts to tell the story of the British Broadcasting Corporation’s transmitting station at Woofferton near Ludlow in Shropshire during the first years of its existence. When and why did the BBC appear in the Welsh border landscape with a vast array of masts and wires strung up in the air? The story begins in 1932, when the BBC Empire Service opened from the first station at Daventry in Northamptonshire. Originally, the service, to link the Empire by wireless, was intended to be transmitted on long-wave or low frequency. But, following the discovery by radio amateurs that long distance communication was possible by using high frequency or short waves, the plan was changed. Later in the decade, the BBC expanded the service by also broadcasting in foreign languages. Although Daventry had a distinguished name in the broadcasting world, it was never technically the best place for a short-wave site, being on a hill and close to a growing town.
Developer Tania Finlayson found her voice through Morse code. Now she’s partnering with Google to bring Morse code to Gboard, so others can try it for accessible communication.
Morse code for Gboard includes settings that allow users to customize the keyboard to their unique usage needs. It works in tandem with Android Accessibility features like Switch Access and Point Scan.
This provides access to Gboard’s AI driven predictions and suggestions, as well as an entry point to AI-powered products, like the Google Assistant.[…]
The number of ARISS (Amateur Radio on the International Space Station) has been lower during the Covid-19 pandemic due to so many schools being closed and relying on remote instruction. Many thanks to SWLing Post contributor, Bruce Atchison, who notes that there will be an ARISS contact tomorrow (February 5, 2021) in Canada.
Listening to an ARISS contact is actually quite easy as long as you’re within the footprint of the ISS during the pass. Almost any radio–a scanner, handheld radio, etc.–that can receive 145.8 MHz can tune in. Click here to read a previous post describing how to listen.
Check out the RAC news item below with full details:
ARISS contact with Ottawa Carleton Virtual Online School: Friday, February 5
Ottawa, Ontario
ARISS Event: February 5, 2021 – As part of the Amateur Radio on the International Space Station (ARISS) program, NASA Astronaut Mike Hopkins, KF5LJG, will connect with students from the Ottawa Carleton Virtual Online School in Ottawa, Ontario and answer their questions (see below), live from the International Space Station (ISS).
The ISS call sign is scheduled to be NA1SS event and the will take place on Friday, February 5, 2021 at 17:41:04 UTC 40 deg via AB1OC. It is recommended that you start listening approximately 10 minutes before this time.
The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and AB10C which is located in New Hampshire:
Ground Station Coordinates:
AB1OC New Hampshire Latitude 42.712N; Longitude 71.590W; Elevation 110m
The contact should be audible over the USA and Canada (Eastern regions) and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English.
Steve McFarlane, VE3TBD, ARISS Central and Northern Canada representative, is the Mentor for the event and Brian Jackson, VE6JBJ, ARISS Western Canada Mentor, is the Moderator.
ARISS is an international program aimed at inspiring students worldwide to pursue interests and careers in science, technology, engineering and mathematics (STEM) through Amateur Radio communications opportunities with the ISS crew.
As mentioned above, members will ask their questions to Astronaut Mike Hopkins, KF5LJG, via an adapted telebridge link which will use a multi-point system in which they are connected to the conference call centre from their own homes.
The concept requires three things:
the ARISS telebridge radio ground station – a satellite Amateur Radio station with special equipment that an ARISS team member uses for teleconferencing
the astronaut on the International Space Station using the ARISS Amateur Radio station
students at their homes here on Earth
The telebridge radio operator links to the astronaut at the ARISS radio mic, and each youth then connects from home via their telephones. Their families can listen along with school faculty and the public from home.
