Tuned Radio
January 28, 2026 • EPISODE 295
How do radios tune in to specific stations? In this episode of Science LIVE, Dr. Roger Billings explores the tuned radio—how circuits are adjusted to select particular frequencies so we can hear one station clearly among many. Learn why tuning is essential for radio reception and how the first wireless radio signal crossed the Atlantic Ocean, launching a new era of global communication.

Older electronics use to be so much bigger than they are now.
How do scientists figure out what is important to study/work on/pursue?
No questions or comments! I enjoyed this episode a lot!
My Mom loves the radio!
Love this! Can’t wait for next week.
Wow! I live so close to Colegate Uni. I will definitely research that more!
i love Dr billings
WiFi just bieng named something completely unrelated to the company will never not be funny.
Thank you Dr. B for another great Science Live!
science is so cool!!
i love science live
Caleb and david are so funny
Think if we didn’t have Wi-Fi or even a radio. Why does Tesla get a lot of the credit for this though.
Learning about the radio is interesting
This was a good science live video can’t wait for the next
what a great episode for us to learn
I am glad to be here today 👍
I Loved this love it was cool!
Wonderful video! Radios are so cool.
you guys the best
The opening joke is my fav part!
I think all of this WiFi is interfering with migration patterns and is overall harmful to the world with it’s EMFs.
What was the biggest challenge in early radio communication.
It is very interesting to learn about the black hole and how its gravity is so compact that it prevents anything from escaping it including light!
This is great I love Dr Billings, I love learning about how these are basically made!
Cool episode!!! Can’t wait till next weeks!!!!
How do you build a robot?
I. Love science live
How many coils can a radio like that one have?
Who came up with the name for Wi-Fi? Also, I love radios so much! The fact that a black hole could eat so much is so cool to me but also kind of scary at the same time. The Culpits ocsilator is so cool I searched it up and it is a type of radio and electronic board.
I think it’s cool how you can use a radio through sound waves or Wi-Fi.
Crazy how people figured out these telegraph things, I would’ve never guessed!
I loved the Wellermen song!
I liked learning about the radio and coils.
this was very interesting
Can’t wait for next week’s video
Black holes are so cool but terrifying at the same time.
This was a interesting video
Interesting to learn that the term Wifi was a random term they came up with. Also interesting to learn how radio waves work.
I love these videos!
Enjoyed hearing about the early days of Wi-Fi connection and how the name came from pretty much nothing with no actual meaning.
I really enjoyed learning about the tuned radio!
Did the S in Morse code mean anything?
i would love to see that pls put it in there pls by the was pls meends pleses
I love this episode! My dad used to be on the radio!
Cool video! Can’t wait for the next one
I loved the joke about Abraham Lincoln and the internet!

i love dr billings.
learning about the tuned radio was very interesting.
The thread computer was super cool!
I found the part about the World’s First Camera was most interesting.
That story about the black hole research contributing to the wifi research was really interesting!
Blue monster galaxy ? that’s new on my terms i will do my research thanks Mr. Joseph
Science is awesome!!
If they make smart clothing with the thread would it be very comfortable?
It’s insane that a transistor can be as small as a thread.
What?! I didn’t know you could a computer in a thread!
It’s crazy that a transistor can be as small as a thread.
How they made the first radio was so cool and fun to learn about! Thanks for another great episode!
Enjoyed learning about this.
looking forward to another episode of science live
The string chip is so cool!
I love science live and learning sbout the radio and the blue monster Galaxies lol.

Hello I luv to learn about the radio and luv science live it’s great to learn so much about science.
Nice history lesson on radios and WIFI.
I would like to learn more about Blue Monster galaxies.
It was very interesting to learn about the new technology of putting a whole computer/computer chip inside a thread, how flexible this is, and how this thread could be weaved into textiles to make smart clothes.
I enjoyed learning about how the work of the Australian engineer John Sullivan in the 1970s helped in the process of inventing Wi-Fi in the 1990s.
Learning about Guglielmo Marconi and how he invented a radio wave-based wireless telegraph system was very interesting as well.
My favorite part is the computer thread
Radio waves are cool
That radio is cool!
I LOVE BLACKHOLES
Learning about the radio was really interesting.

was the James web telescope ever fixed
i learn so much watching science live! i never heard of Samuel Morse or Gugliemlo Macroni before.
Tuned Radio is soooo interesting 📻☢️📡🎙🍢
Is the new thin computer chip used in servers?
How do different channels on radio opperate without interference?
loved this science live and learning about the turn radio.
Really enjoyed this episode
I think smart gloves would be really cool! And I loved r 51s radio and his winter butterfly.
How does a safety pin, a piece of pencil lead, and a razor blade create enough wavelength for it to create a radio?
intresting idea with using the wires instead of a chip for brain implants
Learning about how the radio was invented was really something that I never thought that I would enjoy, but I really did. Also, learning about how Wi-Fi was created, and the small little rolls of computer data was really interesting to me. I may even try to create my own simple radio from scratch, just to see how hard it really was. Thank you Dr. Billings for all the time and effort you put into this!
Enjoyed learning about radio waves
A VR glove would be awesome!
We lost our wifi in the ice storm.
Always love these videos!
Yay my favorite video!
