How do Radios Work?

In the modern era, radio waves control everything. From the tunes in your car driving down the road to the police radio in the car that's pulling you over for not signaling your turn. These waves are undetectable and invisible to human senses but they make up the foundation of modern technology.

While the root of modern connected technologies may be radio waves, the underlying tech that makes radios possible is a rather simple concept to understand. Any person can make a simple radio in their home for a few bucks, which is part of the reason this foundational tech dates back to 1895.

I'm so smart that I didn't even crack the morse code and I went to the comments to check what it was. Get on my level NERDS

[jessicamessica]

"all you need to build your own radio is a battery a penny and .... a radio"

[lefconikiatisg]

I can finally use my Morse code skills:
"I'm concerned"
And it was a bit harder than I thought it would be because there were no spaces between the words

[grantmccollum]

.. -- -.-. --- -. -.-. . .-. -. . -.. (I'm concerned)

That was a cool way to end the video. My Morse code skills are rusty since I haven't used them in years when i used to be an amateur radio operator. Glad to know I can still decipher Morse LOL :-)

"I'm concerned" Thank you for a fun homeschool lesson! This was a great explanation, and my kids 12, 10, 8, and 6 really enjoyed the decoding!

Being a famer I have an electric fence and you could hear the ticking on my medium wave radio and much louder tick on my long wave band, it does not affect FM wave at all.

Me: Explain it to me like I'm 9.
(Watches video)
Me: Okay now explain that to me like I'm 5.

[jhunmichaelibanez]

Wow I actually understood the morse code. Training was worth it

“Im concerned”!!

[RameezLalloo]

that morse code translates roughly to "all hail supreme leader Kim jong un"

[imthedragonlord]

I never could comprehend how when Morse code was used people could tell the difference in where spaces are and when it loops

[minecraftgamer]

It was really helpful. I cnnot describe my felling when i finally understood the radio's working method.

Just hats off for understandable description.
😊

People also forget to put down that AM/FM portable radios are more reliable then electricity and internet if your cell phone don't work cause low battery or has no internet or electricity most of the modern ones can be powered by battery as well as solar power, crank, and most modern ones can charge phones act as light or even use a SOS beacon for getting attention .Good for on the go or tight situations and good way to get information quickly no matter where you are located and easier to operate. With so many different devices it makes it super easy to receive information and communication no matter where you are at and no matter what circumstance. Not only it paved way for information age but it also can save lives such as u know a pandemic ya see here.

You forgot to talk about the filters, without filters you will hear all the channels at the same time, to avoid that you must use a band pass filter

[Alexthebrokkie]

Thank a lot man, you probably worked a lot to get to this professional video .

[justaguyreal]

Incredible how fast radio waves travel instantly nearly at speed of light. Amazing drones can be real time flown in other side of planet. And that computer processes can computer all of that so fast as well. How do the processers computer so fast, AND how are they made or constructed to do so?

[chase_modugno]

Awesome video. Although, I'm still a little confused on how audio (or any media type) doesn't get distorted when "packaged" inside different sine wave lengths.

[ELBI_Ian]

IM CONCERNED

It's fun to learn the basics first before I get licensed.

[billbixby]

"A metal stick?"

Now i've heard it all.

Super great video sans the metal stick comment. 👍

[sqidybilly]

watching that part with the glitch effect and the beeping morse code is actually kinda creepy if your watching this at 2 in the morning, but great video, loved it

[rhealbutler]

I SOLVED IT!!!
