Radio Waves: Zombie Sats, Radio Provides Undemanding Friendship, Boom in New Stations, and One Retailer’s Ham Radio Connection

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 BJ Leiderman and Richard Black  for the following tips:


Long-Lost U.S. Military Satellite Found By Amateur Radio Operator (NPR)

There are more than 2,000 active satellites orbiting Earth. At the end of their useful lives, many will simply burn up as they reenter the atmosphere. But some will continue circling as “zombie” satellites — neither alive nor quite dead.

“Most zombie satellites are satellites that are no longer under human control, or have failed to some degree,” says Scott Tilley.

Tilley, an amateur radio operator living in Canada, has a passion for hunting them down.

In 2018, he found a signal from a NASA probe called IMAGE that the space agency had lost track of in 2005. With Tilley’s help, NASA was able to reestablish contact.

But he has tracked down zombies even older than IMAGE.

“The oldest one I’ve seen is Transit 5B-5. And it launched in 1965,” he says, referring to a nuclear-powered U.S. Navy navigation satellite that still circles the Earth in a polar orbit, long forgotten by all but a few amateurs interested in hearing it “sing” as it passes overhead.[]

Ken Bruce: ‘Radio provides friendship in an undemanding way’ (BBC News)

You wouldn’t normally hear a tractor driving past or birds tweeting in the background of Ken Bruce’s BBC Radio 2 show.

But, if you listen closely, those are just a few sounds you might be able to pick up on now the presenter is broadcasting from his Oxfordshire home.

“I do live in dread of the binmen arriving or the Royal Air Force flying over in extremely noisy Chinooks as they do sometimes,” Bruce laughs. “But so far it’s been fine.”

Bruce’s mid-morning show on Radio 2 – which he has hosted continuously since 1992, following an earlier stint in the 1980s – is particularly popular at the moment as more listeners turn to the radio while confined to their homes.

“At a time like this, people want to hear the news, but they don’t want it all day,” Bruce says. “From my point of view, I’ll pay attention to one news broadcast a day, and after that I don’t really want to know too much unless it’s a major development.

“So escapism is a big part of keeping people feeling right during this and I think we provide a certain amount of that, a chance to put the worries of the world to one side.”[]

The coronavirus is bringing about a boom in new radio stations (The Economist)

MILLIONS OF PEOPLE in lockdown are finding diversion at the flick of a dial. According to Radiocentre, the industry body for commercial radio in Britain, local and national stations reported increases in daily listeners of between 15% and 75% in the second half of March. They’ve got competition. Radio stations offering information, entertainment and reassurance to listeners isolated at home have sprung up from Ireland to Syria, Italy to India. Informal and interactive, many are run by amateurs from their homes, with producers learning the ropes as they go.

In Italy Radio Zona Rossa (Radio Red Zone) began broadcasting from the town of Codogno, the site of the country’s first locally transmitted coronavirus infection, just days after Lombardy went into lockdown on February 21st. Hosted by Pino Pagani, an octogenarian whose co-presenter and friend was killed by the virus in March, the twice-daily programme uses the registered FM frequencies of a local station, Radio Codogno, to provide updates on the spread of the virus and the opening hours of local essential services. Mr Pagani also interviews experts and invites residents to call in for a chat. [Note that the full article is behind a paywall …]

Unclaimed Baggage began from a social distance connection, 1970’s style (Unclaimed Baggage)

Doyle Owens loved radios––specifically ham radios. We don’t use them much these days; most of us don’t even know what they are (for the uninitiated: “ham” is slang for “amateur” radio, and its enthusiasts make a hobby of connecting with each other over radio frequencies). In the ‘60s and ‘70s, it was the equivalent of a group FaceTime call, sans face.

Doyle, call sign K4MUR, went to bed early so he could be on the radio by 4:30am to talk to friends in different time zones all around the world. Some were friends from childhood, friends from his days of service in the Korean War. Most of his friends, however, were friends he’d never met in person, who he knew only from the airwaves. Many of them knew him more intimately than the friends and neighbors he saw every day.

Those mornings were his window into the world outside Scottsboro, Alabama, population 9,324 (in 1970), where he’d been working in insurance since shortly after the Korean War. The insurance business paid, but it bored him to tears. Creative energy ran in his blood: during the Great Depression, his father ran a general store on wheels in rural Alabama, which he used to barter for much needed goods. Doyle knew he was destined for more, but he didn’t know what.

One day, a ham radio friend who worked for Trailways Bus Company in Washington, D.C. let Doyle and his friends in on an unusual problem: the bus line had an accumulating pile of unclaimed bags that they didn’t know what to do with. Doyle’s ears perked up. “How much would you sell it for?” he asked his friend. “Well, I’m not sure,” his friend said. They settled on three hundred dollars.

That afternoon, Doyle borrowed his father’s ’65 Chevy pickup truck and stopped at his father-in-law’s house on the way out of town to borrow three hundred dollars. When he returned, he and his wife Mollie Sue set to unpacking the massive load of luggage. They rented a house on the outskirts of town and set up card tables inside to display the contents of the luggage. Outside, a homemade storefront sign read “Unclaimed Baggage”. That Saturday the doors opened for business, and by the end of the day the tables were empty.

The rest isn’t exactly history. It took many more loads of luggage, many more loans, many more long days and short nights before Doyle’s business grew into the worldwide, fifty-year-old retail phenomenon it is today. But it all started with an idea.

No one knows where they come from, ideas. What we do know is that the right environment––the kind populated by dear friends, clear air, long drives down country roads and the like––clears space for them to land.

The current moment, plagued by uncertainty, financial distress and, well, actual plague, could be seen as less conducive than ever to creativity. Ernest Hemingway once wrote that worry destroys the ability to create, and ill health, which produces worry, attacks your subconscious and destroys your reserves. If we all, like Hemingway, had the ability to combat the malaise with all the fishing, sailing and boxing our hearts desire, we might not be in such a tough spot.[]

“BBC to provide free DAB radios to over-70s”

(Source: IBC via Tony Robbins)

  • BBC Radio to provide free DAB radios to over-70s
  • Radios to be given away due to isolation caused by coronavirus
  • Broadcaster partners manufacturers, retailers and charity for giveaway

The broadcaster’s local radio unit will give away free DAB radio units to over-70s nominated by local listeners, as part of the BBC’s Make a Difference campaign.

The project is running across all 39 of the BBC’s local radio stations in England, with partners – including Argos, Currys PC World, John Lewis & Partners, Pure and Roberts Radio – setting aside thousands of radios to give away.

The radios will be distributed by loneliness charity Wavelength, while manufacturer Duracell has agreed to provide batteries for free for the radios.

Tony Hall, the outgoing director-general of the BBC, said: “Local radio is a lifeline at this time and has never been more important as a source of trusted local news and information, and also as a companion for people who are isolating.

”Make A Difference is already having a huge impact right across the country with 28,000 thousand calls in just five days. It is offering support and practical solutions to people who have nowhere else to turn.

“We want everyone who needs access to the radio to have it, that’s why we’re giving away DAB radios. I’m proud we’ve been able to coordinate this initiative with our partners who have been so generous in offering their resources.”[…]

QSL news for March 2020: Radio Taiwan International and Radio Slovakia International (The Girl with the Radio)

I have some news, first from Radio Taiwan International:
Due to COVID-19, RTI has decided to suspend posting QSL cards to the countries listed in the image [attached].

If you live in any of these countries I would advise you to expect significant delays in receiving a physical QSL card from RTI.

Secondly, Radio Slovakia International have announced on their show that they currently don’t expect to be able to have QSL cards made and/or sent out in a timely manner for quite some time, again due to COVID-19.[]

Radio, Don’t Blow Your Chance to Matter Again (Guest Column — Variety)

Radio, I’ve just about had enough of you and your abandonment of your defining purpose as broadcasters. With the coronavirus pandemic now ravaging everyday life and suspending every reliable comfort from work routines to sports and entertainment or actual human contact, we’re looking for steadiness somewhere — an echo of the familiar, a kindred connection. Anything to tether us to something recognizable. A service the radio dial used to provide — and public radio still does.

Corporate radio is missing its biggest opportunity in a generation right at this moment.

Based on the events of the last few days in Los Angeles, market No. 2 with a 60-plus year history of rich and vibrant local broadcasting excellence, it appears there is little wisdom or vision left. Case in point: the vast audience disconnect in Entercom’s abrupt and confusing decision at KROQ-FM to fire morning show personality Kevin Ryder on Wednesday, someone who is a heritage voice in L.A. with a long local history as half of the “Kevin & Bean Show,” a well-loved talent who had just launched the freshly-formed team “Kevin in the Morning With Allie & Jensen” this past January (in the wake of longtime partner Gene “Bean” Baxter’s retirement last year). But instead of capitalizing on that position of strength, using this particular anchor as a steady ship for the approaching tidal wave of pandemic upheavals, KROQ chooses to obliterate a main source of humor and comfort from its airwaves right at a moment when the attending audience needs stability more than ever.[]

Coronavirus: Radio listening booms while music streaming stalls (Southgate ARC)

BBC News report that people staying at home due to the coronavirus pandemic appear to be listening to more radio rather than music apps, figures suggest.

Global, which owns Capital FM and talk station LBC, said online radio listening had risen by 15%.

The BBC said streaming of its radio stations had risen 18% since last week.

Meanwhile, data from two US analytics companies suggested use of music-streaming apps such as Spotify had dipped by about 8%.

“These figures indicate that the public are turning to radio in times of crisis,” a Global spokeswoman said.

BBC Radio and Education director James Purnell said: “People turn to us during significant events for our news and analysis but also for music, entertainment and companionship.

Experimental Radio News 2

Experimental Radio licenses from the files of the Federal Communications Commission

On February 24, 2020, Lynk’s experimental satellite licensed as WQ9XDP was received on an unmodified mobile phone in the Falklands. The test apparently was in “cell broadcast” mode — as in Wireless Emergency Alerts and Amber Alerts — and not an individualized call to a specific handset. (The video below contains an expletive.)

[…]WJ2XUG was issued to PointView Tech, reportedly a unit of Facebook, for the Athena satellite project in the 70 and 80 GHz bands. At this writing, the public record for this experiment was incomplete as the FCC had asked PointView for additional ground station information.

[…]Viziv Technologies, licensee of WJ2XGB, a giant experimental station in Texas, has proposed additional uses for its technology beyond wireless power transmission.

[…]Another wireless power venture is Guru Wireless, which was issued WK2XRN for tests at 10, 24 and 62 GHz. “Radio wave energy is generated in the GU [generating unit], and then it is refracted and channeled into highly focused beams, which reach and power your devices,” according to the Guru website.

[…]Rohde & Schwarz USA was issued WP9XZP for Special Temporary Authority in association with Microsoft, which is evaluating security scanners apparently for its own use. The Rohde & Schwartz product is a “millimeter wave security scanner that automatically detects potentially dangerous items carried on the body or in clothing. It consists of a flat panel with 3,008 transmitter/receiver pairs that emit extremely low-power millimeter waves in very short succession,” the company said.[…]

Radio Waves: Digitizing Pakistan, BBC MW Closures, Lowe HF-250 Review, and BBC News suspends 450 job cuts

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 Alan, Mike, and Dave Zantow for the following tips:


Government to fully digitize Radio Pakistan (Radio Pakistan)

The incumbent government, under its vision of introducing modern trends and technology in different sectors, has planned to fully digitize the state-owned Radio Pakistan.

This information has been revealed in official documents during the ongoing week-long national workshop on Digital Radio Migration policy of Radio Pakistan at Pakistan Broadcasting Academy, Islamabad.

The digitization will bring about a revolution in the field of broadcasting in the country, and will capture the audience at home and abroad including South Asia and Central Asia and the Middle East through quality news, current affairs and programs.

Under the plan, the biggest 1000-Kilowatt DRM Medium-wave transmitting station of Radio Pakistan will be set up at Fort Monroe hill station in Dera Ghazi Khan district in South Punjab at an estimated cost of three billion rupees.

It will be the first ever most powerful but digital transmitter of Radio Pakistan that is to be established in center of the country as part of Phase-II of Digital Radio Migration policy and it will help cover the entire population of Pakistan with crystal clear and noise-free waves.

The project has already been approved by the federal cabinet while the Punjab government has been asked to acquire land for the said purpose.

Under Phase-II of DRM plan, five DRM+FM transmitters of 10-kilowatt each will be installed in Islamabad, Lahore, Karachi, Faisalabad and Multan in the existing Radio Stations.

Besides, eight DRM+FM transmitters of five kilowatt each will be installed in Quetta, Peshawar, Gilgit, Skardu, Gwadar, Mirpur (Azad Kashmir), Khairpur and Narowal in the existing radio stations.

The phase-II of the plan would be accomplished in three years with an overall estimated cost of 3,153 million rupees.

And under Phase-III of the plan, four DRM medium wave transmitters of 100-kilowatt each will be installed in Lahore, Skardu, Quetta and Peshawar for strategic purposes.[]

BBC Radio to close more medium wave transmitters (Radio Today)

The BBC says it is closing a further 18 medium wave transmitters across England, Scotland and Wales in the next stage of its plan to cut costs.

Services being closed range from BBC Radio Solent’s two AM frequencies on the South Coast to BBC Radio Scotland’s service in Aberdeen.

Six more BBC Local Radio services will no longer be transmitted on AM – they are Three Counties Radio (630 and 1161 kHz), BBC Radio Merseyside (1485 KHz), BBC Radio Newcastle (1458 KHz), BBC Radio Solent and BBC Radio Solent (for Dorset) 999 and 1359 KHz, BBC Radio Cornwall (630 and 657 kHz) and BBC Radio York (666 and 1260 KHz).

Kieran Clifton, Director, BBC Distribution & Business Development explains: “The majority of radio listening in the UK – including to the BBC – is now digital, and digital listening is continuing to grow.

“This change was planned as long ago as 2011, but we have taken a measured approach to implement it to ensure that as many of you as possible have already moved on to other ways of receiving the services before we make this change. We know that the changes will impact some of you, and that’s why we’re speaking about the plans again now. We want to make sure that people listening to these transmissions will be able to use other methods to hear the same programmes.”[]

Dave’s review of the Lowe HF-250 (N9EWO)

[…]As far as audio quality goes, it’s extremely difficult to beat the Lowe HF-250. Mind you it has it’s share of “bug-a-boos” as well.

In our view it has held up much better in it’s old age vs. the AOR AR7030. Properly operating and in decent condition samples are fairly rare on the used market now (even more so in North America). Most owners know what the receiver is and hang on to them. But once a great while one does show up on the used market. Click here to read the full review.

BBC News suspends 450 job cuts to ensure Covid-19 coverage (BBC News)

BBC News has suspended plans to cut 450 jobs as it faces the demands of covering the coronavirus pandemic.

The job losses were announced in January and were part of a plan to complete a £80m savings target by 2022.

Outlets due to be hit include BBC Two’s Newsnight, BBC Radio 5 Live and the World Service’s World Update programme.

Director general Tony Hall gave staff the news on Wednesday, a week after the broadcaster delayed the end of the free TV licence scheme for all over-75s.

Lord Hall said “we’re suspending the consultation on those saving plans”.

He told staff: “We’ve got to get on with doing the job that you’re doing really brilliantly.

“It would be inappropriate. We haven’t got the resource to plough ahead with those plans at the moment, so we’ll come back to that at some point.

“But for the moment we just want to make sure you are supported and you’ve got the resources to do the job that you and your colleagues are doing amazingly.”[]

“BBC sets out plan to inform, educate and entertain during unprecedented times”

(Image source: BBC)

(Source: BBC Media Centre)

Today the BBC is setting out how it will ensure it keeps the nation informed, educated, and entertained in unprecedented times.

Director-General Tony Hall says: “We all know these are challenging times for each and every one of us. As the national broadcaster, the BBC has a special role to play at this time of national need.

“We need to pull together to get through this. That’s why the BBC will be using all of its resources – channels, stations and output – to help keep the nation informed, educated and entertained. We are making a series of changes to our output to achieve that.

“We will continue to deliver all the essential news and information – with special programming and content.

“We also will do everything from using our airwaves for exercise classes for older people, religious services, recipes and advice on food for older people and low-income families, and should schools close, education programming for different age groups. We will also be launching a whole new iPlayer experience for children. And of course there will be entertainment – with the ambition of giving people some escapism and hopefully the odd smile.

“Clearly there will be disruption to our output along the way, but we will do our very best.

“It will take time to emerge from the challenges we all face, but the BBC will be there for the public all the way through this.”

The BBC is announcing a wide-ranging package of measures today.

Our core role is to bring trusted news and information to audiences in the UK and around the world in a fast-moving situation, and counter confusion and misinformation.

In particular:

  • We will do everything we can to maintain Breakfast, the One, Six and Ten and ensure they continue to perform a vital role on BBC One
  • We will broadcast a weekly prime-time Coronavirus special on Wednesdays on BBC One, and move Question Time to 8pm on Thursdays, with call-in audiences and remote guests.
  • We will record a daily edition of the Coronavirus podcast, and film it where possible for
  • News channel use in the UK and abroad.
  • We will bring listeners the most up-to-date information on Coronavirus through 5 Live. 5
  • Live will be answering listeners’ questions with regular phone-ins.
  • We will focus local radio breakfast and mid-morning output on news, open phone lines and expert advice for local communities between 6am and midday.
  • Under the umbrella Make A Difference, every local radio station will join up with local volunteer groups to help co-ordinate support for the elderly, housebound or at risk, making sure people know what help is available in their area.
  • We will keep Newsround bulletins on air throughout the day on CBBC.
  • We will delay the planned closure of the Red Button text news and information service.

We will help people in the UK deal with the impact of the crisis on their own lives, by providing advice, education and support.

Initiatives include:

  • Using The One Show as a consumer programme show for all aspects of the crisis. This will include health and well-being advice, keeping fit and healthy eating tips, as well as links to other BBC output that can help and support.
  • In BBC One daytime, Health Check UK Live will directly address the concerns of viewers who are in isolation, offering tips on how to keep healthy and happy at home.
  • Making BBC Homepage the BBC’s bulletin board supplying clear information – the answers to all the key questions, with public information, health advice and recipes.
  • Launching a virtual church service on Sunday mornings across local radio in England, led initially by the Archbishop of Canterbury.
  • Subject to outside broadcast capacity and our partners, we will aim to broadcast a weekly Sunday morning church service on BBC One, and explore how to support other religions and denominations, including in the run-up to Ramadan.
  • We will work with partners to get older age group exercise routines and other fitness programming into people’s homes on TV or radio.
  • We will retarget the BBC Food website around collections of recipes and advice on what can be made with essentials, especially for older people, and for low-income families.

In the event that schools are shut down, and subject to further work and discussions with the Department for Education, devolved administrations and schools, we are exploring:

  • A daily educational programme for different key stages or year groups – with a complementary self-learning programme for students to follow, broadcast on BBC Red Button and made available on demand on BBC iPlayer.
  • Expanding BBC Bitesize content, with our social media running daily troubleshooting Q&As focusing on a different subject each day.
  • Increasing our educational programming on BBC iPlayer, bringing together the best from BBC Bitesize, BBC Teach and the wider BBC portfolio where educationally appropriate.
    Creating two new daily educational podcasts for BBC Sounds, one for primary and one for secondary.
  • BBC Four and BBC Red Button devoting a block of programming each weekday evening to show programmes that support the GCSE and A Level curriculum. In Scotland, the Scotland channel will support the Scottish NQs and Highers in daytime.

We will keep people entertained, providing laughter, escapism, companionship, shared experiences and a sense of connection to the outside world.

Initiatives include the following:

  • We will bring back many favourite shows, allowing people of all ages to escape into some top-quality entertainment both on our channels and on BBC iPlayer. New boxsets going up shortly include Spooks, The Missing, Waking The Dead, French And Saunders, Wallander and The Honourable Woman, as well as more from BBC Three.
  • We will be launching an exciting new iPlayer experience for children, offering a wide range of entertaining and educational series. It will be easy to use and easy for them to find what’s relevant to them.
  • Radio 1, Radio 2 and Radio 4 will provide the information, explanation and escape that millions rely on. On Radio 4, we will dig into our rich archive of drama with such well-loved titles as The Complete Smiley, all of the novels by the Bronte Sisters, film noir classics by Raymond Chandler, and reassuring favourites as Rumpole and Wodehouse. We will be sharing popular podcast dramas with a wider radio audience for the first time by broadcasting the award-winning Forest 404 and The Whisperer In Darkness. We will also hope to provide some joy and laughter by running classic editions of I’m Sorry I Haven’t a Clue and Just A Minute.
  • We will do the same in BBC Sounds, looking at bringing back classic sport, comedy and drama, as well as exploring using the BBC’s programme index to allow audiences to search thousands of online archive radio programmes.
  • We will aim to create live fund-raising events, to raise money for coronavirus good causes.
  • At a time when British culture is having to close its doors, the BBC, through iPlayer and Sounds, can give British culture an audience that can’t be there in person. We propose to run an essential arts and culture service – Culture in Quarantine – that will keep the Arts alive in people’s homes, focused most intensely across Radio 3, Radio 4, BBC Two, BBC Four, Sounds, iPlayer and our digital platforms, working closely with organisations like Arts Council England and other national funding and producing bodies. This will include guides to shuttered exhibitions, performances from world-class musicians and comedy clubs, new plays created especially for broadcast featuring exceptional talent, poetry and book readings.

Radio Waves: Plant-powered Satellite Comms, BBC Pips, Filter Basics, and Replacing Shortwave

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!

Plant-powered sensor sends signal to space (Phys.org)

A device that uses electricity generated by plants as its power source has communicated via satellite—a world first.

[…]The device can inform farmers about the conditions of their crops to help increase yield, and enable retailers to gain detailed information about potential harvests.

It transmits data on air humidity, soil moisture and temperature, enabling field-by-field reporting from agricultural land, rice fields or other aquatic environments.

The extremely low power device sends signals at radio frequencies that are picked up by satellites in low Earth orbit. It was developed by Dutch company Plant-e and Lacuna Space, which is based in the Netherlands and the UK, under ESA’s programme of Advanced Research in Telecommunications Systems (ARTES).[]

The eccentric engineer: a tale of six pips and how the BBC became the national arbiter of time (Engineering and Technology)

This edition of Eccentric Engineer tells the story of the BBC Time Signal and how, over the years, it has just got more complicated.

Every engineer needs to know the time, if only so as to not miss lunch. Since 1924, many Britons have been checking their watches against the BBC time signal, known affectionately as ‘the pips’.

The history of the ‘pips’ is almost as long as the history of the BBC itself. The first transmissions from what was then the British Broadcasting Company began in late 1922 and soon afterwards there were suggestions of broadcasting a time signal under the control of the Royal Observatory at Greenwich – then the arbiter of time in the UK.

No one seems to have seen a need for this degree of precision, but early broadcasts did use their own ad hoc ‘pips’, marking the 8pm and 9pm news programmes with a time signal consisting of the announcer playing the Westminster chimes on a piano and later a set of tubular bells. This proved rather popular with listeners, who could now adjust their clocks and watches daily, so the BBC decided to invest in some more high-tech clocks from the Synchronome Company. These provided audible ‘ticks’, which the announcer then simply counted down.[]

What Is Replacing Shortwave? (Radio World)

A joint effort is necessary to bring the digitization of radio to a successful end

Analog shortwave will celebrate about 100 years of existence in 2028 when many hope 5G will have been properly defined, tested and applied, though broadcasting is low on its long list of perceived advantages.

It’s true that shortwave was typically a medium of the Cold War that peaked in 1989 and that afterward its listenership dwindled. Many international broadcasters gave up on it as the post-war transmitters got rustier and the energy bills kept mounting.

After all, when budget cuts are needed, no transmitter will go on strike or write to the press, as happened when the BBC World Service tried to unsuccessfully close its Hindi shortwave transmissions in 2011. In 2020 these broadcasts stopped, when committed BBC Indian listeners, writers and thinkers who opposed it in 2011 did not protest too much.

The slow death of shortwave has been blamed on the internet and satellite. As technology and content are inextricably linked, shortwave created its type of content that is no longer favored by the savvy FM listener, internet user and cellphone obsessed.[]

Filter Basics: Stop, Block and Roll(off) (Nuts and Volts)

A casual observer might think that wireless systems consist primarily of filters connected by the occasional bit of circuit! Block diagrams of transceivers often include as many filters as any other function. This is true at the system level, just as it is at the circuit level — and many circuits behave in a filter-like way, whether intended to be a filter or not! That makes understanding filter basics important for wireless success.[]
