Good move #ARRL #hamradio

Thanks, ARRL, for leading the charge to offer electronic voting to League members. 

I hope the effort expands to section elections.

I had a conversation with an election clerk about offering this in government elections. There's a lot of dots to connect, as you know and the QST article revealed, to make it real. 

NOW, if we could do something to approve voter apathy!!

It's disappointing to defend and support the Constitution when less than half of the registered voters  care enough to vote. 

Maybe, electronic elections will help that, too.

#Carrington Event impact to #hamradio

 From the Amateur Radio Newsline on MeWE:

**A “Perfect Coronal Mass Ejection” Could Be a Nightmare**


A new study in the research journal Space Weather considers what might happen if a worst-case coronal mass ejection (CME) hit Earth — a “perfect solar storm,” if you will.


In 2014, Bruce Tsurutani of Jet Propulsion Laboratory (JPL) and Gurbax Lakhina of the Indian Institute of Geomagnetism introduced the “perfect CME.” It could create a magnetic storm with intensity up to the saturation limit, a value greater than the Carrington Event of 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 “extreme levels of flare and interplanetary CME (ICME) shock-accelerated particle radiation,” they said. The event would follow an initial CME that would “clear the path in front of it, allowing the storm cloud to hit Earth with maximum force.”


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.


The CME’s 12-hour travel time would allow little margin for preparation. The CME would hit Earth’s 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.


More recent research led by physicist Dan Welling of the University of Texas at Arlington took a fresh look at Tsurutani and Lakhina’s “perfect CME,” and given improvements in spaceweather modeling, he was able to reach new conclusions.


Welling’s 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 °. “[Our results] exceed values observed during many past extreme events, including the March 1989 storm that brought down the Hydro-Québec power grid in eastern Canada, the May 1921 railroad storm, and the Carrington Event itself,” Welling summarized.


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


Other research has indicated that phenomena such as the Carrington Event may not be as rare as once thought. A much weaker magnetic storm brought down the Canadian Hydro‐Québec system in 1989.


Scientists believe a perfect CME will happen someday. As Welling et al conclude, “Further exploring and preparing for such extreme activity is important to mitigate spaceweather-related catastrophes.”


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

Count this as worse than an ice storm and hurricane combined. Your car won’t start. Your radio won’t work. The electricity is out. That’s ok. Your microwave and refrigerator are fried and you can’t get In Amazon to order another. 

Primitive. Your life just became primitive.

Peggy's Chat #hamradio #Caribbean



One of the best nets on Ham Radio is Peggy's Chat.


Each Saturday morning at 7 a.m. Central Time (1200 Z), listeners can hear Peggy, VP2MP accept checkins from ALL over the world on the CDARIN ... the Caribbean Digital Amateur Radio International Network.  

Occasionally, the Sunflower Net will connect but otherwise users should log on to Echolink 532301 and Allstar 431421, as well as DMR, Fusion, Dstar, and Hamshack Hotline.

Come meet new friends and enjoy old ones on Peggy's Chat.

Everyone! Talk about #hamradio #ARRL

 Everyone talks about the weather but no one does anything about it.

You saw the Tweet:

#ARRL Public Information Officers, Coordinators, and many other member-volunteers help keep amateur radio and ARRL in the news. #hamradio buff.ly/3zoAFHS 

You have friends, neighbors, countrymen willing to lend you their ears.  

Get your "elevator speech" ready.  You have 30 seconds to tell them about your relationship with the Best Hobby on the Planet.

Sometimes folks on 7.200 mHz need to experience Wouff Hong #hamradio #ARRL


 
... because if they did, perhaps they might come away with an understanding of what ham radio is all about.
 
It seems that folks all over the planet are all about antinominanism ...  there's NO law that applies to them (in the strongest sense).

The Author is keenly aware of the Constitution from the Declaration of Independence through to the amendments, especially the first and 14th.
 
Yet, without the Law telling us what we can and can not do, we are no better than anarchy.  
 
Wouff Hong Certificate As a recent inductee to the Royal Order of the Wouff Hong, it was an apparent effort to restore understanding  of what the founders of the amateur radio hobby sought to have understood about the civility of the BEST hobby on the Planet.  

The folks at HamHoliday must be commended, along with the American Radio Relay League, for supplying this clear understanding what the tradition of amateur radio includes as understanding this hobby of ours.

Our Hobby, like our Constitution, will continue to last for more decades when  Citizens and Hams understand the promises of both.
