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.

I learn something new each video
What was the concept of even making computers stem from?
wow it’s cool to see how far laptop’s have came
These are always so interesting!!!!!
Great science live as always, can’t wait for next week!
Are you gonna start making hydrogen computers, or phones?
how a radio works is very interesting
science is so cool!!!
oh wow he just dissapears lol, love the weekly videos.
i love science!
I like the proteges and their mini episodes!
How much computer string would you need to make a shirt.
r51 is so crazy and funny.
That’s really interesting—building your own radio system shows serious creativity and technical skill, especially being able to tune it yourself.
i cant believe how cool it is that the first wireless was made by a noble
r15 is funny
What an informative lesson. Having access to cell phones and computers is an instant form of communication, but watching this video really opens your eyes on how far we have come to get to this point. With Marconi’s invention of wireless telegraphy he was able to achieve the worlds first transatlantic transmission making it possible for people to transmit signals even from a ship. How interesting that because of people like Tesla, Hertz, and Marconi we are able to communicate so easily today.
I love listening to music on the radio. I’m glad it was invented.
What was the first tuned radieo.
It was nice to see the Inventioneers again.

Today was a good science live and hello from Ohio.
Dont believe everything you read on the internet, and how did someone come up with a radio.
I think science live is so cool! I’d like to know when the first radio was made?
I agree that you can’t believe everything you read on the internet.
the pirate skit was funny and R51 your nuts!!
It was so cool to learn about tuned radio.
you shouldt believe everything you read on the internet, when was the worlds first camera. That must have been a while ago.
i LOVE the R51 Radio
The pirate ship scene was so funny.
Ive started listening the the radio more. What a cool invention.

Well the thread end up in computers in the future?
how does that work if you both took each others radio signals?
I love the Ideas y’all came up with.
i love to listen to the radio cause i like the songs
i didnt know the radio was so advanced. The way they tuned it was awesome
I think its so cool with all the inventions and investments for the topic of wifi and the online part of the world. I couldnt even think of the concept of a computer being as small as a thread. Alexandra from Illinois.
I really like Acellus and I understand it so much better. It will be cool to have clothes that have technology made into them. Like a shirt with a screen on the sleeve where you can press buttons to call or search something.
i enjoyed the live video, just got back from a break and area 51 guy brings fun to the video, technology has come a long way from sat phones, telephones to celephones, radio is the same thing but my mom said she wishes we lived in the 80’s as this world is crazy.
I really love science live and I love what they teach me. Radios are so cool.
