FCC proposes $50 fee for new ham radio licenses, upgrades and vanity applications

Many thanks to Paul Evans (W4/VP9KF) who notes that FCC Notice of Proposed Rulemaking–MD Docket no. 20-270–outlines a new fee structure for several radio services including the amateur radio service.

If I understand correctly, a fee would be collected when an FCC employee would need hands-on time to process an application. This would include all new amateur radio applications, license upgrades, and vanity call sign applications.

It appears many routine licence services that could be handled entirely through the FCC ULS system/website without human intervention might remain no-cost.

At least, this is the way I read the information from this FCC Notice of Proposed Rulemaking. Please correct me if I’m wrong.

Click here to download the PDF version of Docket No. 20-270. 

Most of the amateur radio changes are outlined under “personal licenses” staring at section 24.

To be clear, this is a proposal open for comment. These fees have not yet been adopted. I expect the ARRL will have a response.

Radio Waves: Narco-Antennas, Pirate Radio Beginnings, Arqiva Restructure and Redundancies, and the Ghostly Buzzer

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 Skip Arey,  David Goren, Paul Evans, Kanwar Sandhu and Dave Porter for the following tips:


Special Report: Drug cartel ‘narco-antennas’ make life dangerous for Mexico’s cell tower repairmen (Reuters)

MEXICO CITY (Reuters) – The young technician shut off the electricity at a cellular tower in rural Mexico to begin some routine maintenance.

Within 10 minutes, he had company: three armed men dressed in fatigues emblazoned with the logo of a major drug cartel.

The traffickers had a particular interest in that tower, owned by Boston-based American Tower Corp (AMT.N), which rents space to carriers on its thousands of cellular sites in Mexico. The cartel had installed its own antennas on the structure to support their two-way radios, but the contractor had unwittingly blacked out the shadowy network.

The visitors let him off with a warning.

“I was so nervous… Seeing them armed in front of you, you don’t know how to react,” the worker told Reuters, recalling the 2018 encounter. “Little by little, you learn how to coexist with them, how to address them, how to make them see that you don’t represent a threat.”

The contractor had disrupted a small link in a vast criminal network that spans much of Mexico. In addition to high-end encrypted cell phones and popular messaging apps, traffickers still rely heavily on two-way radios like the ones police and firefighters use to coordinate their teams on the ground, six law enforcement experts on both sides of the border told Reuters.[]

How Pirate Radio Rocked the 1960s Airwaves and Still Exists Today (HowStuffWorks)

If you’ve been binge-watching movies lately, you may have come across “Pirate Radio.” Director Richard Curtis’ 2009 comedy-drama stars the late Philip Seymour Hoffman as The Count, a disc jockey for an unlicensed rock radio station that broadcast from a rusty, decrepit ship off the British coast in the mid-1960s, defying government authorities to spin the rock records that weren’t allowed on the BBC at the time. The plot is based loosely on the saga of an actual former pirate station, Radio Caroline, that was founded by an offbeat Irish entrepreneur named Ronan O’Rahilly, the inspiration for the character portrayed by Bill Nighy.

“Pirate Radio” is a period piece, set in a time when the Rolling Stones’ “Let’s Spend the Night Together” and the Who’s “My Generation” were still scandalous and controversial rather than nostalgic anthems for today’s aging baby boomers. So you couldn’t be blamed for assuming that it depicts a long-vanished phenomenon, like Nehru jackets with iridescent scarves and psychedelic-patterned paper mini dresses.

To the contrary, though, more than a half-century later, pirate radio is still a thing. In fact, it’s possibly more widespread than it was in the 1960s, even in an age when streaming internet services such as Spotify and Pandora put the equivalent of a jukebox in the pocket of everyone with a smartphone. And as a bonus, Radio Caroline still exists — though, ironically, it’s gone legal.[]

Arqiva confirms restructure and redundancies (IBC.org)

[Note: Arqiva is the UK domestic broadcast transmission provider.]

Arqiva is working on a restructure of its business that could result in a third of its staff being made redundant.

According to a report in the Telegraph, the media infrastructure business is preparing to cut around 500 staff, which is approximately a third of its workforce.

An Arqiva spokesperson confirmed to IBC365 that some job losses will occur.

They said: “The sale of our telecoms business makes Arqiva a smaller organisation, changes our revenue profile and reduces our available profit pool.

”We are therefore conducting a review of the costs and systems we need to run our business over the next three years.

”Regrettably, we will need to reduce the size of our workforce, but it’s much too early to speculate about numbers.”

The Telegraph report cites the shift to streaming and a drop in income for broadcasters as reasons for the potential cuts.[]

The ghostly radio station that no one claims to run (BBC Future)

In the middle of a Russian swampland, not far from the city of St Petersburg, is a rectangular iron gate. Beyond its rusted bars is a collection of radio towers, abandoned buildings and power lines bordered by a dry-stone wall. This sinister location is the focus of a mystery which stretches back to the height of the Cold War.

It is thought to be the headquarters of a radio station, “MDZhB”, that no-one has ever claimed to run. Twenty-four hours a day, seven days a week, for the last three-and-a-half decades, it’s been broadcasting a dull, monotonous tone. Every few seconds it’s joined by a second sound, like some ghostly ship sounding its foghorn. Then the drone continues.

Once or twice a week, a man or woman will read out some words in Russian, such as “dinghy” or “farming specialist”. And that’s it. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz.

It’s so enigmatic, it’s as if it was designed with conspiracy theorists in mind. Today the station has an online following numbering in the tens of thousands, who know it affectionately as “the Buzzer”. It joins two similar mystery stations, “the Pip” and the “Squeaky Wheel”. As their fans readily admit themselves, they have absolutely no idea what they are listening to.[…]

Radio Waves: Tallest Structure in Italy, Suggestion to Save AM, Online Radio Exams in Australia, and a Letter From Friends of ABC

The tallest structure in Italy is a remote radio transmitter in Sicily. (Atlas Obscura)

WHEN TALKING ABOUT THE TALLEST structures in the world, one often thinks of skyscrapers above modern cities, but radio transmitters in remote locations also reach dizzying heights.

Italy is famous for its many architectural marvels built over the millennia, but its tallest building (a sleek, modern structure in Milan) is only 758 feet tall. The title of the tallest overall structure goes to a radio transmitter on the Sant’Anna hill near the town of Caltanissetta, in Sicily. (In between the two are a number of transmitters and power plant chimneys.) This antenna has a height of 938 feet, and was built by the national public broadcasting company, RAI, between 1949 and 1951. At the time it was also the tallest structure in all of Europe, until 1965 when a transmitting station in the United Kingdom was inaugurated.[]

Here’s a suggestion for how to save AM radio (Los Angeles Daily News)

Last week, I wrote a little about streaming audio and how, with the use of smart speakers, smartphones, and plain old computer streaming, the possibility of internet radio essentially replacing traditional broadcast radio.

This week I want to travel to both the past and one of broadcast radio’s possible futures, spurred on by the ideas presented last week, my absolutely illogical love of AM radio, and a letter to the editor that I read online at radioworld.com.

AM radio broadcasting is almost a century old in the United States – numerous stations in Los Angeles, including KHJ (930 AM), KFI (640 AM) and KNX (1070 AM) will celebrate 100 years of broadcasting in two years. That’s an impressive feat, especially considering the technology is essentially the same as it was in 1922.

As I mentioned last week, digital HD Radio, considered for a time as the savior of both AM — due to higher fidelity — and FM — due to potential higher fidelity and extra stations — just hasn’t made the impact many had hoped. For various reasons, many AM stations have turned off the HD signal, even while FMs continue to use it, and consumers don’t seem all that interested in either. But as I said last week, with smart speakers, what’s the point? And a related question comes up: is broadcast AM radio just a dead technology?

Christopher Boone thinks he has the answers. No, AM is not dead. But if you really want to improve it, bring back a technology that already “failed” … AM stereo.[]

Online remote exam sessions in Australia (Southgate ARC)

VEA (Volunteer Examiners Australia) is pleased to advise we are currently able to perform online remote exam sessions for both AMC and ARRL VE Examinations.

VEA has AMC Level 3 examiners that can conduct remote online examinations.

Also, the ARRL VEC has entrusted us by extension the FCC, to be examiners for FCC-issued license via remote online examinations, a volunteer examiner, must ensure the exam conducted fairly and that there is the same level of integrity as there would be for an in-person examination.

Candidates need to be aware there are conditions and eligibility in registering to do an ARRL online remote examination, e.g. living in a remote location, or the candidate is physically impaired to attend an exam session.

VEA does run bi-monthly AMC and ARRL VE exam sessions during the year,
so if you are interested, visit our website www.vea.org.au complete the online registration form.

VEA currently have AMC and ARRL VE examiners in Queensland, New South Wales, Victoria, South Australia, and Western Australia.

VEA looks forward in supporting the ham radio community in providing this valuable service to both AMC and ARRL VEC.

An open letter to the Prime Minister from ABC Friends and supporters (ABC Friends)

Posted in Latest news from ABC Friends on 28 June 2020

ABC Friends have written an open letter to the Prime Minister in the wake of the recent staff and funding cuts.

Dear Mr Morrison,

I write on behalf of many angry Australians who want to know why your government continues to undermine Australian public broadcasting with ongoing funding cutbacks at the same time as the commercial media sector is favoured.

Your recent statement that “there have been no cuts to the ABC” sadly reminds us of Tony Abbott’s similar bold election promise in 2013, yet this was followed by major cutbacks in his first Budget as Prime Minister. Clearly in our current media environment there are facts and ‘alternative’ facts, it all depends on the presenter and the audience.

Many of us are more inclined to rely on information from your ABC Board Chair, Ita Buttrose, who said in her 2019 Forward to the Annual Report – “our task has been made harder by the imposition of the three year indexation freeze which comes on top of a $50 million a year cut now embedded in our base.”

We see the recently announced Five Year Plan as a brave attempt by the Managing Director, David Anderson, to live within your governments funding allocation, but obviously further staff cuts and downgrading of ABC services and programs is an inevitable outcome of reduced funding.

We all appreciate that governments rely on a degree of political spin to make their decisions seem more palatable, but do you seriously expect the community to believe that an ABC Managing Director would deliberately retrench so many staff and downgrade services and programmes if the ABC Budget was adequate?

We expected more of your leadership because you have a responsibility to act on our behalf, as ABC shareholders to enable the ABC to fulfil parliamentary approved obligations under its Charter. The Federal Government acts as caretaker of all our national institutions and in this regard the ABC ranks highly with the Parliament and the High Court in protecting the interests of all Australians.

Chair of the ABC Board, Ita Buttrose has consistently tried to work with you and your Communications Minister, Paul Fletcher, to get a realistic re-assessment of the ABC Budget to meet the demands of a changing media environment and national emergencies. Yet these genuine efforts by both Board and Management have been repeatedly ignored. Furthermore, there has been a quite calculated misrepresentation of budgetary analysis since 2014 assuming that official promotion of fake news will provide an effective distraction from the reality of past and current government decision making, which has resulted in an ongoing 10% budget reduction.

Over the past six years the ABC has been the target of funding cuts, various enquiries, political attack and even a police raid. You can not be surprised that Australians are outraged about the latest announcement this week which will culminate in further job losses, valued services and Australian content. You regularly advocate protection of jobs and your COVID-19 employment protection initiatives are admirable. Yet successive Coalition administrations have caused the loss of 1250 ABC professional staff.

Can you explain to us why you are so determined to downgrade the ABC, which is a valued national treasure supported by over 80% of Australians? We understand that you are regularly lobbied by the Murdoch American News Empire and other commercial media interests, which are ideologically opposed to public broadcasting. Furthermore, we know that some members of your cabinet are members of the Institute of Public Affairs, which advocates privatisation of the ABC. However, ABC Friends would respectfully remind you that, as Prime Minister, your first loyalty is to the Australian people and our public institutions.

As a national organisation we have been overwhelmed by expressions of public concern about the way the ABC is being treated. So many comments express ongoing frustration that many of our elected representatives seem incapable of recognising the ABC as an essential public service on which Australians depend. We have received hundreds of letters and comments which we will be collating for public release, but here is just one example to offer you some insight into how Australians feel about the continued assault on the ABC.

“I am shocked, then saddened, then disgusted, then outraged by the governments attack on the ABC. The Federal Government should be creating jobs instead of destroying high quality ‘clever country’ jobs. Prime Minister Morrison led a government that was unique in bringing together differing interests across Australia to benefit the nation and lead us out of disaster. But now? The attack on the ABC is a fundamental attack by the Morrison Government on its claim to govern in the national interest.”

We urge you to reconsider your government’s responsibilities to the ABC by conducting immediate meaningful negotiations with the Ms Buttrose and Mr Anderson to plan a way forward to restore ABC funding. This discussion should include a commitment in the October Budget to recognise ABC staff and services as essential in post COVID-19 planning .

We look forward to a fresh approach to public broadcasting policy and can assure you such commitment will be very much welcomed by the Australian public.

Yours sincerely,

Margaret Reynolds
National President
ABC Friends

Credit Card Crystal Radio

Many thanks to SWLing Post contributor, Paul Evans, who shares this article from Hackaday that highlights a crystal radio built completely on a smart chip credit card by Billy Cheung.

Hackaday notes:

This is possible because the smart chip on many credit cards contains a diode. It’s then a simple matter of hooking up the right pads on the credit card to the rest of a crystal radio circuit, and you’re all set. Of course, [Billy] goes the whole hog, building the entire radio on a single credit card. Other cards are cut up to create bobbins for winding coils to form a variable inductor, used to tune the radio. Doing this allows for a much cleaner, thinner design, rather than using a variable capacitor which is comparatively hard to find. Turning the dial allows stations to be tuned in, and with a high impedance earbud hooked up, you’re listening to AM radio. Oh, and don’t forget an antenna!

Cheung documented the whole process and even shares templates via links in the description of his YouTube video.

Many thanks to Paul and Hackaday for sharing this fun project!
