Starlink has launched home Internet service to 99.5% of residents in the National Radio Quiet Zone (NRQZ) after a multi-year collaboration with the National Radio Astronomy Observatory to minimize interference with radio telescopes. "The vast majority of people within the areas of Virginia and West Virginia collectively known as the National Radio Quiet Zone (NRQZ) can now receive high speed satellite Internet service," the National Radio Astronomy Observatory and Green Bank Observatory announced said. "The newly available service is the result of a nearly three-year collaborative engineering effort between the US National Science Foundation (NSF), SpaceX, and the NSF National Radio Astronomy Observatory (NSF NRAO), which operates the NSF Green Bank Observatory (NSF GBO) in West Virginia within the NRQZ." Ars Technica reports: There's a controversy over the 0.5 percent of residents who aren't included and are said to be newly blocked from using the Starlink Roam service. Starlink markets Roam as a service for people to use while traveling, not as a fixed home Internet service. The Pendleton County Office of Emergency Management last week issued a press release (PDF) saying that "customers with the RV/Roam packages had been using Starlink for approximately two years throughout 100% of the NRQZ. Now, the 0.5% have lost coverage after having it for two years. This means that a large section of southeastern Pendleton County and an even larger section of northern Pocahontas will NOT be able to utilize Starlink."

PCMag wrote that "Starlink is now live in 42 of the 46 cell areas around the Green Bank Observatory's telescopes." Pendleton County Emergency Services Coordinator Rick Gillespie told Ars today that Roam coverage was cut off in the remaining four cell areas. "After the agreement, we all lost effective use within the four cells," Gillespie told Ars in an email. Gillespie's press release said that, "in many cases, Starlink was the only Internet provider option residents and emergency responders had. This is unacceptable."

OFF Radio Krakow sparked controversy by replacing its journalists with AI-generated presenters in an experiment to attract younger audiences. CNN Business reports: Weeks after letting its journalists go, OFF Radio Krakow relaunched this week, with what it said was âoethe first experiment in Poland in which journalists ... are virtual characters created by AI." The station in the southern city of Krakow said its three avatars are designed to reach younger listeners by speaking about cultural, art and social issues including the concerns of LGBTQ+ people. "Is artificial intelligence more of an opportunity or a threat to media, radio and journalism? We will seek answers to this question," the station head, Marcin Pulit, wrote in a statement.

The House Energy and Commerce Committee has approved the AM for Every Vehicle Act, which mandates that automakers include AM radio in new vehicles without additional charges. The Verge reports: The bill passed the committee on a roll-call vote of 45-2 and now heads to the full House for final approval. The bill, titled the AM for Every Vehicle Act, would direct the National Highway Traffic Safety Administration (NHTSA) to issue a rule that "requires automakers to maintain AM broadcast radio in their vehicles without a separate or additional payment, fee, or surcharge." Supporters say they are pushing the bill out of a concern that the slow demise of AM radio could make it more difficult to broadcast emergency information during a natural disaster or other related events. Conservatives are also worried about losing a lucrative platform for right-wing news and media. [...]

Automakers generally see AM radio as an obsolete technology, arguing that there are other, better technologies, such as internet streaming, HD radio delivered on FM bands, or some apps that provide AM content that will make up for the absence of AM radio in vehicles. Critics say the bill could also add to the costs of producing EVs at a time when many manufacturers are struggling to rein in their costs. "With a new mandate, [EV companies] will have to go through a significant powertrain redesign, vehicle redesign," Albert Gore, executive director of the Zero Emission Transportation Association, said in an interview earlier this year, "because of the degree to which electric motor generates this [electromagnetic] interference."

Digital audio broadcasting (DAB+) and internet radio have largely replaced traditional FM radio in Switzerland, with digital radio holding an 81% share of use in spring 2023. Due to the high costs of maintaining FM transmitters and declining financial resources, Switzerland plans to fully transition to digital radio by the end of 2026, phasing out FM broadcasting completely. From a report: DAB+ and the internet offer better quality and a larger program selection, are more energy and cost efficient, and can provide additional information in text and images, it said. To receive DAB+ requires a corresponding device or adapter, and new cars have been equipped with digital technology as standard for several years. In addition, the Federal Roads Office (FEDRO) will upgrade all tunnels on the national road network for digital radio reception by the end of the year and switch off FM transmitters.

FM was originally expected to be switched off throughout Switzerland by the end of 2024. The government extended FM licenses for the radio industry for the last time in October 2023 to the end of 2026, after which radio stations in Switzerland will no longer be able to broadcast via FM, only digitally. OFCOM announced at the time that the final extension would give the radio industry the flexibility to complete the transition process from analogue to digital radio.

Apple has quietly added a Thread radio to nearly all of its newest iPads, MacBooks, and iMacs. The Verge reports: While the company doesn't list Thread on the specs of any of these products, FCC reports indicate that many of Apple's latest devices have had Thread radios tested for compliance. Generally, you don't test a radio that's not there. We found evidence of Thread testing in the following models: iPad Pro 13-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi), iPad Air 11-inch (M2) (Wi-Fi + Cellular), iPad Air 13-inch (M2) Wi-Fi, MacBook Air 15-inch (M3), MacBook Pro 14-inch (M3), MacBook Pro 14-inch (M3 Pro or M3 Max), MacBook Pro 16-inch (M3 Pro or M3 Max), iMac (M3, two ports), and iMac (M3, four ports).

The FCC requires manufacturers to list every radio contained in a device and to test them in every possible scenario to make sure they comply with its transmission regulations. Tom Sciorilli, director of certification for Thread Group, told The Verge that the FCC reports reference FCC 15.247, "which confirms the device will essentially 'stay in its lane' and not interfere with other radios when operating." The reports we found are tests of the IEEE 802.15.4 transmitter functionality -- 802.15.4 is the radio standard Thread runs on. While it supports a number of technologies, the reports mention Thread explicitly.

Thread is the primary wireless protocol for the new smart home standard Matter, which Apple helped develop and that is now the underlying architecture for its Apple Home smart home platform. A low-power, low-bandwidth, mesh networking protocol specifically designed for IoT devices, Thread is shown to be faster than Bluetooth and offers better range, making it ideal for connecting products like smart lights, locks, thermostats, and sensors. [...] So why is it there? The Apple Home app runs on Macs and iPads, and Thread radios could allow them to communicate directly with smart home devices and act as Thread border routers. It's possible Apple is planning to turn your Mac or iPad into a home hub, but iPads used to be home hubs, and the company discontinued that capability for its new Apple Home architecture. Those iPads didn't have Thread radios, though.

An anonymous reader quotes a report from Ars Technica: A controversial bill that would require all new cars to be fitted with AM radios looks set to become a law in the near future. Yesterday, Senator Edward Markey (D-Mass) revealed that the "AM Radio for Every Vehicle Act" now has the support of 60 US Senators, as well as 246 co-sponsors in the House of Representatives, making its passage an almost sure thing. Should that happen, the National Highway Traffic Safety Administration would be required to ensure that all new cars sold in the US had AM radios at no extra cost. "Democrats and Republicans are tuning in to the millions of listeners, thousands of broadcasters, and countless emergency management officials who depend on AM radio in their vehicles. AM radio is a lifeline for people in every corner of the United States to get news, sports, and local updates in times of emergencies. Our commonsense bill makes sure this fundamental, essential tool doesn't get lost on the dial. With a filibuster-proof supermajority in the Senate, Congress should quickly take it up and pass it," said Sen. Markey and his co-sponsor Sen. Ted Cruz (R-Texas).

About 82 million people still listen to AM radio, according to the National Association of Broadcasters, which as you can imagine was rather pleased with the congressional support for its industry. "Broadcasters are grateful for the overwhelming bipartisan support for the AM Radio for Every Vehicle Act in both chambers of Congress," said NAB president and CEO Curtis LeGeyt. "This majority endorsement reaffirms lawmakers' recognition of the essential service AM radio provides to the American people, particularly in emergency situations. NAB thanks the 307 members of Congress who are reinforcing the importance of maintaining universal access to this crucial public communications medium." "Requiring the installation of analog AM radios in automobiles is an unnecessary action that would impact EV range, efficiency and affordability at a critical moment of accelerating adoption," said Albert Gore, executive director of ZETA, a clean vehicle advocacy group that opposes the AM radio requirement. "Mandating AM radio would do little to expand drivers' ability to receive emergency alerts. At a time when we are more connected than ever, we encourage Congress to allow manufacturers to innovate and produce designs that meet consumer preference, rather than pushing a specific communications technology," Gore said in a statement.

Jason Rainbow reports via SpaceNews: SpaceX has secured conditional approval to use extremely high-frequency E-band radio waves to improve the capacity of its low Earth orbit Starlink broadband constellation. The Federal Communications Commission said March 8 it is allowing SpaceX to use E-band frequencies between second-generation Starlink satellites and gateways on the ground, alongside already approved spectrum in the Ka and Ku bands. Specifically, SpaceX is now also permitted to communicate between 71 and 76 gigahertz from space to Earth, and 81-86 GHz Earth-to-space, using the up to 7,500 Gen2 satellites SpaceX is allowed to deploy.

SpaceX has plans for 30,000 Gen2 satellites, on top of the 4,400 Gen1 satellites already authorized by the FCC. However, the FCC deferred action in December 2022 on whether to allow SpaceX to deploy the other three-quarters of its Gen2 constellation, which includes spacecraft closer to Earth to improve broadband speeds. The regulator also deferred action at the time on SpaceX's plans to use E-band frequencies, citing a need to first establish ground rules for using them in space. In a March 8 regulatory filing, the FCC said it found "SpaceX's proposed operations in the E-band present no new or increased frequency conflicts with other satellite operations." But the order comes with multiple conditions, including potentially forcing SpaceX to modify operations if another satellite operator also seeks to use the radio waves.

A group of radio enthusiasts known as the "radio squirrels" are keeping the legacy of Morse code alive at KPH Maritime Radio, the last operational Morse code radio station in North America. Located in Point Reyes National Seashore, north of San Francisco, the station transmits maritime news and weather reports every Saturday, using vintage equipment dating back to World War II, reads a fast-paced story on The Atlantic. Despite the obsolescence of Morse code, the radio squirrels, along with a 17-year-old newcomer, are determined to preserve this unique form of communication.

A radio station in Alabama has been forced to temporarily shut down after thieves stole a 200ft radio tower. The Guardian reports: WJLX, a station in Jasper, Alabama, was ordered to go off air by the Federal Communications Commission (FCC) after thieves took the station's AM tower last week, the Guardian first learned. "In all my years of being in the business, around the business, everything like that, I have never seen anything like this," WJLX's general manager, Brett Elmore, told the Guardian. "You don't hear of a 200ft tower being stolen," he added.

Elmore said the theft was first discovered last week by a landscaping crew that regularly manages the area nearby the tower, WBRC reported. "They called me and said the tower was gone. And I said, 'What do you mean, the tower is gone?'" Elmore said. The radio tower was previously located in a wooded area, behind a local poultry plant. Elmore said that thieves had cut the tower's wires and somehow removed it. Thieves also stole the station's AM transmitter from a nearby building.

For the small radio station, the theft has had a significant impact. Elmore said the station's property was not insured. Replacing the tower could cost the station anywhere between $100,000 to $150,000, which is "more money than we have," Elmore said. The FCC also notified WJLX on Thursday morning that the station would have to go off the air because of the theft. While WJLX still has its FM transmitter and tower, it is not allowed to operate its FM transmitter while the AM station is off the air. "I had a guy from Virginia call yesterday and say, 'You know, I think a helicopter grabbed [the tower],'" Elmore said. He's hoping that surveillance video from the nearby poultry plant or witnesses nearby can help figure out who stole the station's tower.

An anonymous reader quotes a report from Phys.Org: A NASA telescope has captured the biggest solar flare in years, which temporarily knocked out radio communication on Earth. The sun spit out the huge flare on Thursday, resulting in two hours of radio interference in parts of the U.S. and other sunlit parts of the world. Scientists said it was the biggest flare since 2017. Multiple pilots reported communication disruptions, with the impact felt across the country, said the government's Space Weather Prediction Center.

Scientists are now monitoring this sunspot region and analyzing for a possible outburst of plasma from the sun, also known as a coronal mass ejection, directed at Earth. The eruption occurred in the far northwest section of the sun, according to the center. NASA's Solar Dynamics Observatory caught the action in extreme ultraviolet light, recording the powerful surge of energy as a huge, bright flash. Launched in 2010, the spacecraft is in an extremely high orbit around Earth, where it constantly monitors the sun. The sun is nearing the peak of its 11-year or so solar cycle. Maximum sunspot activity is predicted for 2025.

Long-time Slashdot reader sandbagger shares a report from the Canadian Broadcasting Corporation (CBC): CBC and Radio-Canada have announced they'll no longer carry the National Research Council (NRC) time signal. Monday marked the last time it was broadcast, ending the longest running segment on CBC Radio. In a statement, spokesperson Emma Iannetta described the signal as a "wonderful partnership," but confirmed it's being dropped. Given the range of CBC platforms from traditional over-the-air radio, to satellite and the internet, the long dash undergoes a range of delays by the time it's heard, leading to accuracy concerns from the NRC, she wrote. Iannetta added that nowadays most people use their phones to get the time, though many CBC listeners have a "fondness" for the signal.

For many, the relationship with the time signal goes far beyond fondness. It's allowed sailors to set their instruments for navigation, kept railway companies running on time and helped Canadians stay punctual. In a 2019 interview with Day 6 on the occasion of the signal's 80th birthday, Laurence Wall, one of its current voices, reflected on its origin and importance. His memories include taxi drivers recognizing his voice from daily announcements and hearing from a young man living in Hong Kong who would stay up past midnight just to hear the time signal because it reminded him of home. Beyond emotional connections, the signal has a practical history too. Wall said when it started out, timekeeping was relatively primitive, with watches and clocks that needed to be regularly set in order to stay accurate.

On Tuesday, Apple unveiled the iPhone 15 Pro and Pro Max featuring USB-C ports, titanium bodies, and Action Buttons. They're also the first smartphones to support the open-source smart home protocol Thread. The Verge's Jennifer Pattison Tuohy explains how Apple might deploy this wireless connectivity protocol in its ecosystem: The obvious use for Thread in the iPhone is as a Thread border router for the slew of new Apple Home and Matter-enabled Thread smart home devices from companies like Eve, Nanoleaf, and Belkin WeMo. This would mean you wouldn't have to have a HomePod Mini, Apple TV 4K, or other Thread border router to use Thread smart home gadgets with your iPhone. ... [Jonathan Hui, VP of technology at the Thread Group and a software engineer at Google] says that Thread connectivity in a smartphone will allow it to communicate directly with a Thread device. "Compared to existing smartphones without Thread, a smartphone with Thread can communicate directly with a Thread device, without relying on a separate Thread border router or any other communication technology," he said.

Another possibility with direct control is some type of trigger or presence detection. Your Thread devices could know you're home as soon as you walk into the house and respond appropriately. However, presence detection -- something the smart home sorely needs -- would be easier to do with the UWB chips already in most iPhones and HomePods (and is already being done to some extent). As an IP-based mesh protocol, Thread could be a more reliable way to connect multiple such devices to your phone while also having multiple "parent" devices within the same home (such as your iPad, MacBook, or other family member's iPhones). Its IP characteristic makes it easier to maintain a persistent data connection directly to the device, says Moneta. Additionally, Thread being mesh means your device doesn't have to be in range of the controller (iPhone/iPad etc.), as it would with Bluetooth. This could apply to Apple accessories such as the Apple Watch and third-party devices that use Bluetooth, like camera accessories and medical devices. Of course, all of those would need a Thread radio in, too, so that's not going to happen anytime soon. [...]

A popular theory in my X (formerly Twitter) feed after the Apple event was that Thread is in the iPhone 15 Pro line more or less as a freebie. It's plausible that the Wi-Fi / Bluetooth chip Apple is using in its highest-end phones comes as a sort of three-for-one: you pay for Wi-Fi and Bluetooth, and you get your Thread for free! Given that Apple itself doesn't seem to have a clear idea or any concrete examples of what the Thread capabilities will add (beyond a vague "opening up future opportunities for Home app integrations" statement in the iPhone 15 press release), this does seem to be the most likely reason -- for now. Although, Apple rarely does anything without some purpose in mind.

An anonymous reader quotes a report from Reuters: The U.S. Senate Commerce Committee approved legislation on Thursday to bar automakers from eliminating AM broadcast radio in new vehicles and require companies like Ticketmaster to put total ticket prices including fees in marketing materials. The AM radio bill and the ticket-pricing bill both had strong bipartisan support and both have companion measures in the House of Representatives. The AM radio bill would direct the Transportation Department to issue regulations mandating AM radio in new vehicles without additional charge. Senators said this year that at least seven automakers have removed AM broadcast radio from their electric vehicles, including Tesla, BMW, and Volkswagen. Ford reversed course in May under pressure from Congress. Lawmakers say losing AM radio undermines a federal system for delivering key public safety information to the public. The National Association of Broadcasters said the bill "will ensure that the tens of millions of AM radio listeners across the country retain access to local news, diverse community programming and emergency information." The Alliance for Automotive Innovation, a trade group representing major automakers, opposed the measure: "This is simply a bill to prop up and give preference to a particular technology that's now competing with other communications options and adapting to changing listenership."

The U.S. Senate Commerce Committee also approved two bills aimed at tightening privacy protections for children online.

Ford is reversing course on AM radio. From a report: In a tweet today, CEO Jim Farley announced the company was backing off its decision to release new vehicles without AM radio broadcast capabilities. Instead, all 2024 Ford and Lincoln models will be able to tune in to AM radio. And for the two electric vehicles released without AM radio capabilities, a software update would be pushed to restore it. The announcement came after Farley said he spoke with policy leaders on the "importance of AM broadcast radio as a part of the emergency alert system." A bipartisan group of lawmakers introduced legislation in Washington last week that would require automakers to keep AM radio in all their vehicles. The bill was proposed in response to an increasing number of vehicles coming out without the first-generation radio broadcast technology.

A bipartisan group of lawmakers wants to make it illegal for carmakers to eliminate AM radio from their cars, arguing public safety is at risk. From the report: AM radio is one key way that government officials communicate with the public during natural disasters and other emergencies. Officials worry that if drivers don't have access, they might miss important safety alerts. Some manufacturers are eliminating AM radio from their electric vehicles (EVs) because of interference from the electric motors that creates annoying buzzing noises and faded signals.

They argue that car owners can still access AM radio content through digital streaming packages or smartphone apps (though such services sometimes require a subscription). While AM might seem like a relic of the past, nearly 50 million people still listen to it, according to Nielsen figures provided by the National Association of Broadcasters. The proposed legislation, to be introduced today by Senators Edward J. Markey (D-Mass.), Ted Cruz (R-Tex.) and others, would require all new vehicles to include AM radio at no additional charge. In the case of EV models that have already eliminated AM radio (from BMW, Ford, Mazda, Polestar, Rivian, Tesla, Volkswagen and Volvo), carmakers would be required to disclose the lack of AM access to consumers. The law would also direct the Government Accountability Office to study whether alternative communication systems are as effective in reaching the public during emergencies.

An anonymous reader quotes a report from Motherboard: The Federal Communications Commission (FCC) is using a new law to fine a pirate radio station operating in New York City for more than $2 million. For 15 years, Impacto 2, which has been operated by two brothers, has broadcast Ecuadorian news, culture, sports, and talk-radio on 105.5 FM in Queens. The feds have tried to shut it down repeatedly, but have never succeeded. The FCC announced the fine in a press release (PDF) last week. "The Commission proposed the maximum penalty allowable, $2,316,034, against brothers Cesar Ayora and Luis Angel Ayora for pirate radio broadcasting in Queens, New York," the release said. The FCC also said it was trying to seize $80,000 in equipment from a man broadcasting pirate radio in Eastern Oregon.

The FCC closely polices radio spectrums around the country, and provides licenses to companies who apply for specific frequencies. On the one hand, this makes sense, because use of radio frequencies are limited by physics and, without licenses, radio would be a free-for-all. Currently, the FCC is not providing any new FM or AM radio frequencies, according to its website. At the same time, pirate radio has a long history of providing access to the airwaves for independent broadcasters. In this case, the targets of the fine are a pair of brothers who were providing a vital community resource. In court documents about the fine, the FCC detailed its history with the Ayoras and Impacto 2. [...]

According to the FCC, the Ayoras have admitted to operating the radio station several times during interviews. The feds even went to the trouble of totaling every day it could prove the pair had run the radio station and detailed what it would like to charge them for it. "Based on the severity of the facts underlying these factors, we propose the maximum penalty of $115,80265 for each day of the 184 days during which the Ayoras operated their pirate radio station in 2022 for a total penalty of $21,307,568," the FCC's court documents said. That is, however, not possible under the new PIRATE Act. "We reduce the proposed penalty from $21,307,568 to $2,316,034 based on the statutory limits imposed by section 511(a) of the Act," it said in court documents.

The new 2024 Ford Mustang is losing its AM radio receiver, reports The Drive. A Ford spokesperson confirmed the feature's deletion, citing that "countries and automakers globally are modernizing radio by offering internet streaming through mobile apps, FM, or digital." From the report: The availability of AM radio in new cars has declined over the last decade with shifts in media consumption habits, with AM radio's audience evaporating in Europe and accounting for only a small minority of the U.S. population. [...] It's a trend of concern to current and former U.S. emergency officials, who recently wrote the Secretary of Transportation a letter advising action on AM radio's disappearance. AM radio is a crucial component of the U.S.'s national alert network, with just 75 stations reaching more than 90 percent of the country's population. Officials are concerned that AM receivers' decreasing availability in new cars could compromise their ability to reach citizens during emergencies.

The BBC is celebrating the centenary of its first official broadcast - a news bulletin that included a court report from the Old Bailey, details of London fog disruption, and billiards scores. From a report: It was broadcast by London station 2LO, but new research shows many early BBC moments came from northern England. Manchester station 2ZY aired the first children's show and introduced the first regular weather forecast. Birmingham's 5IT station broadcast the first "official concert" The BBC that began broadcasting at 6pm on 14 November 1922 was not the British Broadcasting Corporation of today. It was in fact the British Broadcasting Company and was made up of separate stations around the country operated by different companies. London 2LO was run by the Marconi company. Manchester's station was operated by Metropolitan-Vickers. However, in these early days few records were kept of what was broadcast.

But new research on the BBC's very early days has been carried out by Steve Arnold, a self-confessed Radio Times obsessive. His tricky task was to try to piece together the BBC's schedules before the Radio Times - so named as it listed the times that the new medium's shows were being broadcast - was first published in September 1923. He explained he found information in "gossip columns [in regional newspapers] mainly, people saying we listened to this last night and this is the only record of some of these things". Now, using sources from archive documents and newspapers, Steve has begun to piece together a picture of what the early BBC was doing. He says the Manchester station, which operated out of Trafford Park, seems to have been the best organised. "It looks as though the Manchester station is probably the origins of the BBC as much as the Marconi 2LO station (in London)," he said. "They seem to have had a far more professional approach. There's a lot more documentation and it seems they knew their onions. I'd love to know more."

Longtime Slashdot reader and tech historian, Kay Savetz, shares a blog post about the Internet Archive's efforts to build a library of amateur radio broadcasts. Here's an excerpt from the report: Internet Archive has begun gathering content for the Digital Library of Amateur Radio and Communications (DLARC), which will be a massive online library of materials and collections related to amateur radio and early digital communications. The DLARC is funded by a significant grant from the Amateur Radio Digital Communications Foundation (ARDC) to create a digital library that documents, preserves, and provides open access to the history of this community. The library will be a free online resource that combines archived digitized print materials, born-digital content, websites, oral histories, personal collections, and other related records and publications. The goals of the DLARC are to document the history of amateur radio and to provide freely available educational resources for researchers, students, and the general public. [...]

The DLARC project is looking for partners and contributors with troves of ham radio, amateur radio, and early digital communications related books, magazines, documents, catalogs, manuals, videos, software, personal archives, and other historical records collections, no matter how big or small. In addition to physical material to digitize, we are looking for podcasts, newsletters, video channels, and other digital content that can enrich the DLARC collections. Internet Archive will work directly with groups, publishers, clubs, individuals, and others to ensure the archiving and perpetual access of contributed collections, their physical preservation, their digitization, and their online availability and promotion for use in research, education, and historical documentation. All collections in this digital library will be universally accessible to any user and there will be a customized access and discovery portal with special features for research and educational uses.

Some carmakers are leaving AM radios out of their new cars. They say it's because of audio quality, but it isn't that simple. James Gilboy writes via The Drive. From the report: BMW and Volvo told me it was due to audio quality problems rooted in electromagnetic interference, of which EVs' drivetrains produce a significant amount. Cars' engines and other complex electronics have always made EM interference, but low-wattage static is relatively easy to shield against. It's not as simple with EVs that may pull hundreds of watts from their batteries, generating far more interference, reducing audio quality to a level both BMW and Volvo told me they consider insufficient. But it's hard to take them at their word when EVs are built with AM radios and in no small numbers. Detroit's Three -- Ford, General Motors, and Stellantis -- have produced or currently make EVs that include AM radio, even on flagship models. That goes for the Ford F-150 Lightning and Mustang Mach-E, GM EVs from the Cadillac Lyriq to the Chevy Bolt EUV and GMC Hummer EV, and even Stellantis's almost-forgotten Fiat 500e. Clearly, some carmakers don't think EM interference is a problem, and some EV owners agree. One user of an EV forum user said that AM radio "works fine" in their 500e and older Chevy Bolt.

We contacted all three of Detroit's giants for why they continue to include AM radios when some European makes have phased them out, but the answer establishes itself across those very same lines. AM radio has fallen out of favor in Europe, with Radio Info reporting in 2015 that stations were shutting down en masse from France to the Netherlands and Russia. The frequency has largely been superseded by the DAB format, which is a more advanced form of radio broadcasting with better audio quality and choice of stations. AM radio stations and their listeners are all but gone in Europe, so European carmakers may not need to include technology that many of its customers can't use.

In the U.S., on the other hand, radio remains a must for car buyers, with 89 percent of responders in a 2021 survey stating radio should be standard in new cars. That makes radio even more important to U.S. car buyers than USB ports, which only 84 percent said were necessary. AM audiences were in rapid decline as of a 2017 report by Inside Radio, but not to enough a degree for American carmakers to leave AM radios out of their products. It's not hard to figure out why AM's holding on here, either: AM signals travel further than FM broadcasts do and are cheaper to transmit, allowing them to cater to audiences in sparsely populated areas. Audio quality can't compare, but that's secondary to having anything to listen to at all in some parts of the continental United States.
