What a Ham I am (part 7) - Ham Radio, where are you?

 



It's been a while since I've posted on this subject--Ham Radio.

In the early days, ham radio had been the cutting edge of tech and worldwide communications. Hearing a voice or a signal on the other side of the planet seemed like a miracle.

But the times are changing, especially with the ubiquitous cell phones and the internet. And during these times, ham radio with its old demands of morse code and passing tests to operate seems to be on the outs.



Or is it?


Yet, the hobby is alive and well for over 100 years with over 750,000 licensed operators in America.



When cell towers go down and power is out, ham radio can still get through with messages on emergency power. And the thrill of making contact with evolving innovations still draws many to the hobby.

There is an annual exercise to prepared for a worst-case disaster scenario. It's called Field Day, coming up every fourth weekend of June: Field Day - ARRL

Also, amateur radio operators convene throughout the year:  Hamfests and conventions

Ham radio operators are a fraternity/sorority. In my area, the local club, CPREG, Cloud Peak Radio and Electronics Group: Join Our Ham Radio Club Today!

Meanwhile...

Keep Calm
and
Ham Radio
On

Space (part 5) - Perseverance

 


Perseverance!

Its definition according to Merriam-Webster:

continued effort to do or achieve something despite difficulties, failure, or opposition : the action or condition or an instance of persevering : STEADFASTNESS

These qualities capture the essence of the latest NASA mission to Mars.  Thomas Zurbuchen, the associate administrator of the agency's Science Mission Directorate, explained:

"Yes, it's curiosity that pulls us out there, but it's perseverance that does not let us give up." 

Perseverance was chosen from its naming contest for students K-12.  The winning essay was written by seventh grader Alex Mather. For the full story:  What's in a name: Why NASA chose 'Perseverance' for its next Mars rover

And for an overview of this latest mission: Mars Perseverance Mission Overview

Perseverance was launched, July 30, 2020, in the midst of the COVID-19 crisis, another testament to its name:



February 18, 2021, Perseverance successfully landed on Mars, a shown in this animation:


Yea!

Modern marvels of technology recorded the actual landing:




And what a magnificent view!

Check out Mastcam-Z's First 360-Degree Panorama:



Thus Perseverance joins her four sister rovers: Sojourner, Spirit and Opportunity,  and Curiosity.

So the Maritain Chronicles continue as we persevere!

Tech (part 1) - The Gospel and Tech

Gospel/wikipedia.com
Twitter is one of the popular networks in social media. It can connect us to countless people across the world. Through it, we can quickly share information. And that can be vital during disasters.

Tweets can also divide us, incite mob rule to pile on a hapless twitterer of an unpopular opinion. And it's so easy to snipe from the anonymity of a keyboard.

Likewise, the words and action of public figures can divide us. As we approach Easter, we have a perfect example of that, 2000 years ago.  That is Jesus, of course. And the mob had Him crucified. Only He did not stay dead. That's why we celebrate Easter.

How Jesus divided people is recorded in the Gospels. And there is a good booklet (in pdf format) describing this, provided via the modern marvels of computers and hyperlinks:  The Cross Divides Men

The Gospel and 21st century tech 

If you are reading this blog, it is a marvel of our social media, like blogging. And I most likely tweeted the link you are reading, or posted it on Facebook, or you googled it on your browser.

How would the Gospel be told via twitter in our times? Below is a video embedded from YouTube (another modern marvel) showing that:



So in the 21st century, tweets and posts with hyperlinks can quickly spread the Gospels across the world.

The Gospel and 1st century tech 

During the first Easter, the tech of the times also prepared the world to spread the Gospel.

Alexander the Great conquered the known world and made Greek the universal language of its time. They also translated the Jewish Torah (Old Testament) into Greek, known as the Septuagint.

Later the Romans conquered most of the known world.  They built roads, brought law and order, and peace and security to most of its denizens, known as the Pax Romana.

The New Testament was written mostly in Greek, the universal language of the known world. And the apostles like St. Paul, spreading the Gospel, traveled down the Roman roads in the relative safety provided by the Pax Romana,

So these military and technological feats paved the way to spread the Gospel.

[Reference:  Preparation of the World for Christianity ]

The Great Commission

So to this day, the disciples followed one of Jesus' last commands before leaving this earth, using the tech of the times-whether the 1st or the 21st century:

Then Jesus came to them and said, 
“All authority in heaven and on earth 
has been given to me. 

Therefore go and make disciples of all nations, 
baptizing them in the name 
of the Father and of the Son and of the Holy Spirit, 
and teaching them to obey 
everything I have commanded you. 

And surely I am with you always, 
to the very end of the age.”

Matthew 28:18-20 (NIV)

So on this note begins another thread - Tech.

From 20 centuries of tech of the times, may readers continue to receive the blessing this Easter.

Signs of the Times (Part 7) - Leap Second - the new Y2K?

Wikipedia/Leap Second - June 30, 2012

Remember 1999?  

You must be an old timer then.  :)  It was last century. Actually last millennium. Back then, we were all bracing for the dreaded ...

Y2K - the year 2000

For some, it was the End of the World. And for grins, here are some of those predictions of Armageddon, nuclear holocaust, the End Times:  10 Failed Doomsday Predictions (2009)

Side note:  It's interesting when Jesus spoke of the End Times while on earth, He said He didn't know the date. Only the Father in Heaven knew the day and the hour.  (reference: Matthew 24)  Amazing how many people claim to know more about this than Jesus!

Back to Y2K, 2000 years after Jesus ...

For others, Y2K meant the Millennium Bug (which could have meant the end of the world). Our computers, which we have become so dependent upon for everything it seems, were not ready to handle the roll over from December 31, 1999 to January 1, 2000. [reference: Y2K bug from Encyclopaedia Britannica]

This clip, a parody on the cartoon Godzilla, expresses the concern, humorously.



Time marched on. And there were glitches as the calendar rolled from 1999 to 2000. But  we survived. Since we are still here, the end of the world didn't happen ... yet.  :)

Next scare ...

December 21, 2012 - End of the World 

At least according to the Mayans. Or so they say. [reference: The Mayan Calendar - predicting the end of the world?]

And the Mayan calendar spawned this disaster movie - 20122012 | Sony Pictures

Yet, there were skeptics that it was just another day:



We're still here. And there is an explanation for that: Mayan Calendar And The End-Of-The-World Explained

Now, in the coming week we are facing a ...

Mini-Y2K, the Leap second - midnight, June 30, 2015 

To adjust our standardized clocks, a second will be added to our year. An extra second should be no biggie.  Again, it's the old we-are-so-dependent-upon-computers thing.  This extra second could really screw us up:  Leap second on June 30 will be 'mini-Y2K'

The dreaded leap second, coming this June 30, is explained here:



But this has happened 25 times since 1972 and the last time was 2012,  which caused computer problems. Yet, we survived the 2012 leap second and the Mayan calendar scare.  It wasn't the End of World ... yet ;)

See you on July 1 ... Lord willing ...

Timing is everything in this world of hi-tech, which is just another one of the ....
