FCC Issues Nine Warnings To Miami Area Landowners And Property Managers For Illegal Radio Broadcasts (FCC Press Release)

The PIRATE Act Prohibits Landowners and Property Managers from Aiding Pirate
Radio Operations

WASHINGTON, July 21, 2023—The FCC’s Enforcement Bureau today issued nine warnings to landowners and property managers in the Miami area for apparently allowing illegal broadcasting from their properties. The FCC may issue a fine exceeding $2 million if it determines that a party continues to permit any individual or entity to engage in pirate radio broadcasting from any property that they own or manage.

“Providing a safe haven for pirate radio operations that can interfere with licensed broadcast signals and fail to provide emergency alert system notifications can have serious consequences for landowners and property managers that allow this conduct to occur on their properties,” said Loyaan A. Egal, Chief of the Enforcement Bureau. “I want to thank our field agents for their continued efforts to ensure compliance with federal law in this area.”

The Notices of Illegal Pirate Radio Broadcasting sent today target properties identified by
Enforcement Bureau field agents as sources of pirate radio transmissions. These notices formally notify landowners and property managers of the illegal broadcasting activity occurring on their property; inform landowners and property managers of their potential liability for permitting such activity to occur on their property; demand proof that the illegal broadcasting has ceased on the property; and request identification of the individual(s) engaged in the illegal broadcasting.

The PIRATE Act provides the FCC with additional enforcement authority, including higher
penalties against pirate radio broadcasters of up to inflation-adjusted amounts of $115,802 per day with a maximum of $2,316,034. In addition to tougher fines on violators, the law requires the FCC to conduct periodic enforcement sweeps and grants the Commission authority to take enforcement action against landlords and property owners that willfully and knowingly permit pirate radio broadcasting on their properties.

The Notices of Illegal Pirate Radio Broadcasting are available at:

Falling in love by morse code (ABC Radio)

You may know someone who met the love of their life through writing letters, and these days you’d be hard pressed to NOT know people who’ve met online… but have you ever come across someone who’s met her husband in Morse code?

Ulla Knox-Little knew that getting to do an expedition to Antarctica as the radio room operator would be a life-changing experience, but she never expected it to lead to her meeting the love of her life.

Bouvard Laments “Yawning Gap” in Marketer Perceptions About Radio (Radio World)

Cumulus publishes analysis to counter prevailing sentiments about AM and radio in general

“Ford owners are massive users of AM radio.”

So writes Pierre Bouvard, chief insights office of Cumulus Media, citing data from MRI Simmons.

That is but one of his observations as Cumulus Media/Westwood One released an analysis of listening data from sources that also include the Nielsen fall 2022 survey, Edison Research’s “Share of Ear” and research by Advertiser Perceptions.

Bouvard regularly posts about the power of radio and what he calls misperceptions about the medium among the broader marketing community.

He summarized takeaways from the new Cumulus analysis:

“The Nielsen Fall 2022 survey reveals that 82,346,800 Americans listen to AM radio monthly; 57% of the AM radio audience listens to news/talk stations, the very outlets that Americans turn to in times of crisis and breaking local news; and one out of three American AM/FM radio listeners are reached monthly by AM radio,” he wrote.

AM News Radio, your go-to in a crisis, could itself be in trouble (NorthJersey.com)

“Some clouds over the city right now. I’m Paul Murnane,” says a familiar voice.

“I’m Wayne Cabot,” says another.

Few would know their faces. But as names, they’re as recognizable as anyone in New York.

Fewer still could tell you their address — an 11th floor studio in a light-brick high-rise in lower Manhattan, between a Chase bank branch and patisserie named Maman.

But hundreds of thousands know where to find them on the AM dial — right between 820 WNYC (“public affairs”) and 930 WPAT (“multi-ethnic”). That, for 56 years, has been the location of WCBS Newsradio 880 — one of those rare unchanging institutions in a changeable city. [Continue reading…]

Apollo Comms Part 27: Quindar Tones Microphone Hack (CuriousMarc on YouTube)

The last DJ nears? Radio station uses artificial intelligence, cloned voices (WRAL)

GENEVA — The voices sound like well-known personalities, the music features trendy dance beats and hip-hop syncopations, and the jokes and laughter are contagious. But listeners of an offbeat Swiss public radio station repeatedly got the message on Thursday: Today’s programming is brought to you by Artificial Intelligence.

Three months in the making, the French-language station Couleur 3 (Color 3) is touting a one-day experiment using cloned voices of five real, human presenters — in what managers claim is a world first — and never-aired-before music composed almost entirely by computers, not people. From 6 a.m. to 7 p.m., the station said, AI controlled its airwaves. Every 20 minutes, listeners got a reminder. Continue reading

Gen Tojo’s Teeth: Morse Code Shows Up In The Strangest Places (Hackaday)

The Baader-Meinhof effect is the common name for what scientists call frequency illusion. Suppose you are watching Star Trek’s Christopher Pike explain how he makes pasta mama, and you’ve never heard of it before. Immediately after that, you’ll hear about pasta mama repeatedly. You’ll see it on menus. Someone at work will talk about having it at Hugo’s. Here’s the thing. Pasta mama was there all along (and, by the way, delicious). You just started noticing it. We sometimes wonder if that’s the deal with Morse code. Once you know it, it seems to show up everywhere.

One of the strangest places we’ve ever heard of Morse code appearing is the infamous case of Tojo’s teeth. If you don’t remember, General Hideki Tojo was one of the main “bad guys” in the Pacific part of World War II. In particular, he is thought to have approved the attack on Pearl Harbor, which started the American involvement in the war globally. Turns out, Tojo would be inextricably tied to Morse code, but he probably didn’t realize it. [Continue reading at Hackaday…]

M5STICKC Turned Wearable Morse Code Trainer (Hackaday)

Have you ever felt the options for Morse code communication were too limited? Well, look no further than [marsPRE]’s open source WristMorse communicator that can connect over WiFi, can act as a Bluetooth keyboard or just be used as a Morse Code trainer.

[marsPRE] uses the M5StickC Plus as the base device and attaches a custom “hat” consisting of a 2.5 mm plug for a radio connection and two capacitive touch paddles that act as the Morse Code keyer. The add-on is housed in what looks like a custom 3D print and hangs off of the end of the M5StickC Plus, connecting the hat through an eight 0.1 inch pin header. [Continue reading at Hackaday…]

Sister Boniface episode “Dead Air” is a pirate radio-themed

Many thanks to SWLing Post contributor, Harry Dence, who writes:

Do you watch BritBox? Hope so!

Today they released Season 2, Episode 8 of the Sister Boniface mysteries, called “Dead Air.”

Set in England of the Radio Caroline era, the episode concerns a pirate radio station called Radio Catherine, a bit of humor along with the mystery, and an homage to Radio Caroline in its ending. Also a sight gag that will please Spinal Tap fans and reference to the GPO controlling the airwaves.

Thank you for the tip, Harry! 

WeAreBroadcasters: “Encourage Congress to support local radio!”

Note: this is a petition managed by WeAreBroadcasters in opposition to a proposed tax:

Encourage Congress to support local radio!

Legislation that would force local radio stations to pay new fees simply for playing music has been introduced in Congress. The American Music Fairness Act (AMFA) would put stations out of business and impact their ability to provide the news, traffic, weather, emergency information and entertainment you rely on every day. The Local Radio Freedom Act opposes new performance fees on local radio stations and recognizes radio’s vital role in every community. Please take action today and encourage your members of Congress to oppose the AMFA and cosponsor the Local Radio Freedom Act. Your voice matters!

Radio Nacional Arcangel San Gabriel picked up around the world (Radio Nacional)

Radio Nacional Arcangel San Gabriel broadcasts on the short wave on Wednesdays from 21 to 23 UTC and on Saturdays from 21 UTC until 03:00 on Sunday on frequency 15476 Khz (USB).

Due to improvements in the audio chain and transmission line and good propagation, we are receiving messages from listeners who had not been able to listen to it for decades and also reception reports from countries such as India, Iceland, Japan, United States, Spain, Italy, United Kingdom, Mexico, Chile, Brazil, Uruguay and all the National territory.

During the summer we broadcast a program called “Uniendo Voces”, a production of the Joint Antarctic Command, the University of Quilmes and RAE, with the presentation of Juan Carlos Benavente.

Morse Code Clock For Training Hams (Hackaday)

It might seem antiquated, but Morse code still has a number of advantages compared to other modes of communication, especially over radio waves. It’s low bandwidth compared to voice or even text, and can be discerned against background noise even at extremely low signal strengths. Not every regulatory agency requires amateur operators to learn Morse any more, but for those that do it can be a challenge, so [Cristiano Monteiro] built this clock to help get some practice.

The project is based around his favorite microcontroller, the PIC16F1827, and uses a DS1307 to keep track of time. A single RGB LED at the top of the project enclosure flashes the codes for hours in blue and minutes in red at the beginning of every minute, and in between flashes green for each second.

The Changing Face of Tabletop Radios (Radio World)

While some still offer OTA reception, the specialty segment is dominated by online connectivity

There was a time, of course, when radios were fixtures in people’s homes. But according to Edison Research’s “Infinite Dial 2022” report, the percentage of U.S. homes with “zero” radios inside went from 4% in 2008 to 39% in 2022.

Among the radios that remain, clock and emergency radios have the best chances of justifying their presence to internet-centric consumers. But good ol’ fashioned tabletop radios? AM/FM receivers housed in eye-appealing laminated wood cases with big speakers and hefty knobs?

Mass-market companies such as Panasonic and Sony have abandoned such products. But specialty/quality brands such as C. Crane, Grace Digital, Sangean and Tivoli Audio have not.

These brands bring fresh approaches to the tabletop radio segment through innovation and the harnessing of streaming technology. Still, it’s an uphill battle in a world obsessed with all things internet.

There are several reasons conventional AM/FM tabletop radios have been disappearing from homes.

The first and most obvious is that even by the beginning of this century, radio had long ceased being a destination medium around which the family gathered to listen. In recent decades, the more common uses were morning wakeups, rush-hour commutes, sports on the go and weather emergencies, all well-served by portable radios, though there was still some degree of at-home listening.  [Continue reading…]

Morse Code is making a comeback! Children as young as FIVE are learning the once groundbreaking form of communication – spurred on by K-Pop bands who use it to leak hints about upcoming songs to fans (Daily Mail)

Despite being created 180 years ago and not being a requirement for amateur radio operators to learn since 1990, it has been kept alive by radio enthusiasts – and now more young people are getting involved.

A combination of pandemic lockdowns forcing youngsters to learn something new, and the use of Morse Code by popular K-Pop bands, has led to ‘a renaissance’ in teens wanting to learn the once groundbreaking form of communication.

From five-year-olds to 99-year-old war veterans, people all over the world are tapping in to communicate with others on the radio. [Continue reading…]

Ham radio tunes in to a new generation (The Times)

As he sits in a shed on the outskirts of Cambridge, Martin Atherton twists a radio dial and picks up a message being sent in Morse code. The audio dots and dashes, familiar from black-and-white war films, might seem to be relics of a past era.

But more than a century after it was first used, this mode of communication appears to be making a comeback. Since 2006 the number of amateur radio licences, which allow holders to send Morse and voice messages, has increased by almost 60 per cent, according to the Radio Society of Great Britain.

Last year the number of 13 to 44-year-olds viewing the society’s online tutorials, which cover topics such as “improving your Morse skills” and how to build your own equipment, more than tripled.

Allowing people to reach out to distant lands on a shoestring budget, the hobby could have been tailor-made for lockdown. The Netflix series Stranger Things, in which a “ham” radio set is used to contact another dimension, has also been linked to an increase in interest.

“Teenagers are picking it up, so are retirees,” said Atherton, 69, a member of the Cambridge University Wireless Society. [Continue reading…]

Pirate Radio (Twenty Thousand Hertz – The stories behind the world’s most recognizable and interesting sounds.)

In the 1960s, the BBC had a vise grip on British radio, and rarely played the pop and rock music that was all the rage. So a group of rebellious radio DJs decided to give the people what they wanted, and started broadcasting popular music from boats stationed in international waters. Soon enough, these young DJs became national superstars… until the British government decided it was time to sink these pirates once and for all. This story comes from the History This Week podcast.
