Radio Waves:\u00a0 Stories Making Waves in the World of Radio<\/h2>\n

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\u00a0SWLing Post<\/em>\u00a0readers.\u00a0 To that end:\u00a0Welcome to the\u00a0SWLing Post\u2019s<\/em> Radio Waves<\/em>, a collection of links to interesting stories making waves in the world of radio.\u00a0<\/strong>Enjoy!<\/strong><\/p>\n

Many thanks to\u00a0SWLing Post<\/em> contributors Eric McFadden, Mike Terry, for the following tips:<\/p>\n

A \u201cPerfect Coronal Mass Ejection\u201d Could Be a Nightmare (ARRL News)<\/a><\/h3>\n

A new study<\/a><\/strong>\u00a0in the research journal\u00a0Space Weather<\/em>\u00a0considers what might happen if a worst-case coronal mass ejection (CME) hit Earth \u2014 a \u201cperfect solar storm,\u201d if you will.<\/p>\n

In 2014, Bruce Tsurutani of Jet Propulsion Laboratory (JPL) and Gurbax Lakhina of the Indian Institute of Geomagnetism introduced the \u201cperfect CME<\/a><\/strong>.\u201d\u00a0It could create a magnetic storm with intensity up to the saturation limit, a value greater than the\u00a0Carrington Event<\/strong><\/a>\u00a0of 1859, the researchers said. Many other spaceweather effects would not be limited by saturation effects, however. The interplanetary shock would arrive at Earth within about 12 hours, the shock impingement onto the magnetosphere would create a sudden impulse of around 234 nanoteslas (nT), and the magnetic pulse duration in the magnetosphere would be about 22 seconds. Orbiting satellites would be exposed to \u201cextreme levels of flare and interplanetary CME (ICME) shock-accelerated particle radiation,\u201d they said. The event\u00a0would follow an initial CME that would \u201cclear the path in front of it, allowing the storm cloud to hit Earth with maximum force.\u201d<\/p>\n

The Solar and Heliospheric Observatory (SOHO) has observed CMEs leaving the sun at speeds of up to 3,000 kilometers per second, and many instances of one CME clearing the way for another have been recorded.<\/p>\n

The CME\u2019s 12-hour travel time would allow little margin for preparation. The CME would hit Earth\u2019s magnetosphere at 45 times the local speed of sound, and the resulting geomagnetic storm could be as much as twice as strong as the Carrington Event. Power grids, GPS, and other services could experience significant outages.<\/p>\n

More recent\u00a0research<\/a><\/strong>\u00a0led by physicist Dan Welling of the University of Texas at Arlington took a fresh look at Tsurutani and Lakhina\u2019s \u201cperfect CME,\u201d and given improvements in spaceweather modeling, he was able to reach new conclusions.<\/p>\n

Welling\u2019s team found that geomagnetic disturbances in response to a perfect CME could be 10 times stronger than Tsurutani and Lakhina had calculated, especially at latitudes above 45 to 50 \u00b0. \u201c[Our results] exceed values observed during many past extreme events, including the\u00a0March 1989 storm<\/a><\/strong>\u00a0that brought down the Hydro-Qu\u00e9bec power grid in eastern Canada, the\u00a0May 1921 railroad storm<\/a><\/strong>, and the Carrington Event itself,\u201d Welling summarized.<\/p>\n

A key result of the new study is how the CME would distort and compress Earth\u2019s magnetosphere. The strike would push the magnetopause down until it\u2019s only 2 Earth-radii above Earth\u2019s surface. Satellites in Earth orbit would suddenly find themselves exposed to a hail of energetic, and potentially damaging, charged particles.<\/p>\n

Other research has indicated that phenomena\u00a0such as the Carrington Event may not be as rare as once thought. A much weaker magnetic storm brought down the Canadian Hydro?Qu\u00e9bec system in 1989.<\/p>\n

Scientists believe a perfect CME will happen someday. As Welling\u00a0et al<\/em>\u00a0conclude, \u201cFurther exploring and preparing for such extreme activity is important to mitigate spaceweather-related catastrophes.\u201d<\/p>\n

In July 2012, NASA and European spacecraft watched an extreme solar storm erupt from the sun and narrowly miss Earth. \u201cIf it had hit, we would still be picking up the pieces,\u201d said Daniel Baker of the University of Colorado at a NOAA Space Weather Workshop 2 years later. \u201cIt might have been stronger than the Carrington Event itself.\u201d<\/p>\n

FCC To Auction Off 140 Radio Stations (Radio Ink)<\/a><\/h3>\n

The FCC has announced that on July 27th an auction will be held for 136 FM construction permits and 4 AM\u2019s. In this auction, the 130 FM permits that were previously included in the March 2020 auction, that had to be canceled due to COVID, will be included plus an additional 6 permits. Anyone who applied for stations in the planned 2020 auction must reapply. All applications for the previous auction have been dismissed.<\/p>\n

[…]You can see the FM stations to be auctioned off HERE<\/a>.<\/p>\n

The Commission is proposing a simultaneous multiple-round auction format. This type of auction offers every construction permit for bid at the same time and consists of successive bidding rounds in which qualified bidders may place bids on individual construction permits. Typically, bidding remains open on all construction permits until bidding stops on every construction permit.<\/p>\n

Why There\u2019s More Music on AM Now (Radio Survivor)<\/a><\/h3>\n

by\u00a0Paul Riismandel<\/p>\n

A number of months ago I was scanning around the AM dial late in the evening from my Portland, Oregon abode. I stumbled upon a station playing hard rock, which I thought to be an unusual find. As the AM dial has become mostly the domain of conservative and sports talk, I rarely encounter music that isn\u2019t a bumper or part of some leased-time foreign-language programming.<\/p>\n

In fact, at first I thought perhaps the music was a lead-in to just another talk show, but eventually I heard a full set of three songs. The station identified itself as \u201cThe Bear,\u201d but curiously gave an FM frequency, not one on the AM dial.<\/p>\n

An internet search the next day confirmed that \u201cthe Bear<\/a>\u201d is indeed an active rock formatted station located in Merced, California. Its logo features 105.7 FM prominently, with the 1660 AM frequency tucked in the corner. Yet, the AM signal is actually the primary one \u2013 the FM is a 250 watt repeater (translator) station.<\/p>\n

Here\u2019s a quick aircheck of the Bear\u2019s station ID, during a break in the syndicated hard rock \u201cLoudwire\u201d program.<\/p><\/blockquote>\nhttps:\/\/www.radiosurvivor.com\/wp-content\/uploads\/2021\/01\/The-Bear-Merced-CA-ID-2020.10.14_01.mp3<\/a><\/audio>\n

Now, AM stations have been permitted to get FM translators for a few years now as part of the FCC\u2019s\u00a0so-called \u201cAM revitalization\u201d initiative<\/a>. But mostly I\u2019ve heard sports and news\/talk stations get repeated on FM.<\/p>\n

I filed away this experience in memory, but kind of considered it a one-off. That was until my recent vacation in the\u00a0Wallowa Mountains<\/a> of Northeastern Oregon. Stowed away and social distancing in a mountainside cabin with limited internet and no cable, I spent quite a bit of time scanning the AM and shortwave bands in search of interesting sounds.
