A second magnetic field discovered

(Source: Southgate ARC)

The ESA just discovered a second magnetic field surrounding our planet

A trio of satellites studying our planet’s magnetic field have shown details of the steady swell of a magnetic field produced by the ocean’s tides.

Four years of data collected by the European Space Agency’s (ESA) Swarm mission have contributed to the mapping of this ‘other’ magnetic field, one that could help us build better models around global warming.

Physicist Nils Olsen from the Technical University of Denmark presented the surprising results at this year’s European Geosciences Union meeting in Vienna, explaining how his team of researchers managed to detail such a faint signature.

“It’s a really tiny magnetic field,” Olsen told BBC correspondent Jonathan Amos. “It’s about 2 – 2.5 nanotesla at satellite altitude, which is about 20,000 times weaker than Earth’s global magnetic field.”

On a fundamental level, both fields are the result of a dynamo effect produced by charged particles being sloshed around in a fluid.

The stronger magnetic field that tugs on our compass needle forms from the steady movement of molten rock deep under our feet.

This field also leaves its signature in the alignment of particles embedded in Earth’s crust, a pattern that has also been analysed in detail by Swarm

KCRW: The Rise of Pirate Radio Station WBAD

SWLing Post readers: check out this amazing audio documentary by our friend David Goren about the legendary hip hop pirate radio station WBAD. It’s part of a new series from KCRW called Lost Notes.

David shares the following note:

“Endless thanks to DJ Cintronics, and Dren Starr for sharing their stories. Thanks also to Myke Dodge Weiskopf and Nick White of KCRW for their incredible, skillful work and dedication bringing this to fruition.

If by chance you are not a hip hop fan, I would still encourage you to listen to this compelling two person narrative about people who love music and the lengths they go to put it on the air.”

The FCC’s mission to shut down pirate radio

Recently, there have been numerous articles regarding FCC Chairman Ajit Pai’s efforts to increase pirate radio enforcement. This article in The Outline is a worthy read and features our good friend David Goren prominently:

The FCC wants pirate radio stations off the air

Immigrant communities rely on these unlicensed broadcasts to stay connected to their roots. Now they could lose the signal.

On any given night, David Goren can tune into more than 30 underground radio stations from his apartment in Flatbush, Brooklyn. “About a dozen of them broadcast in Creole, to the Haitian community,” Goren, a local journalist and producer who researches the city’s pirate stations, told The Outline. “A lot of the stations will air news from home.” In addition to news and politics updates, Goren said, these stations feature Caribbean music that doesn’t get airtime on mainstream stations, advertisements for local businesses, and occasional call-in sessions with immigration attorneys.

For some immigrant communities across the country, these underground radio stations are an easy way of staying connected to one’s roots. In New York City, there may be more unlicensed broadcasters than licensed ones. Some of these clandestine broadcasters are small enterprises, while others are full-fledged stations that run advertisements and generate revenue. All of them run the risk of being fined — or in some states, including New York, New Jersey, and Florida, having their operators imprisoned — if they’re caught by the Federal Communications Commission.

[…]A map of enforcement actions on the FCC’s website illustrates the crackdown. The FCC has undertaken 306 pirate investigations since Pai took office in January 2017. The majority of these actions — 210, according to a press release issued by the agency on Wednesday — were Notices of Unauthorized Operations, warnings from the FCC telling the unlicensed stations to immediately shut down or risk fines and prison time. The release also notes that the FCC “took more than twice as many actions against pirate broadcasters” in 2017 than it did the previous year. (For the first time since its inception, the agency said, it has begun holding property owners liable for “supporting this illegal activity on their property.”)[…]

Blackloud SounDot AF1 earphones offer FM reception for iPhones

Many thanks to SWLing Post contributor, Richard Langley, who shares this article from Radio World. Here’s an excerpt:

Headsets Deliver FM to Mobile Devices, No Chip or Internet Required

[The BLACKLOUD SOUNDOT AF1] headsets are nothing like the ones you might remember from your first Sony Walkman. According to information provided by Blackloud, SounDots feature patented psychoacoustic technology, a six-band customizable graphic equalizer, 3D stereo effect, dual dynamic driver design, inline microphone, and a control box with a volume up (+), volume down (–) and multifunction (pause/play) button. This multifunction button enables many actions depending on the app that is running, including: answer/hang up a phone/video call, start/stop recording or playback using most any audio/video/camera app, enable/disable/seek up/down the FM tuner, and lastly, activate Siri or Google Assistant.[…]

Richard notes that we’ve posted articles in the past focusing on the fact that iPhones (and a number of Android phone models) do not have or allow user access to a built-in FM reception chip.

Richard sees the new Blackloud SounDot AF1 earphones as an elegant work-around and has pre-ordered a set. If these earphones live up to their specs, they should sound fantastic.

Richard, I hope you’ll post a review after you put them into service! Thanks for the tip!
