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.

loved this weeks video
what if we made a radio that could float
this was a enjoyable episode!
hi from Texas
we need that radio in the store!
This is interesting! I enjoyed this topic
I can’t help thinking about the threads with the computers in them. They could be woven into clothes and track your health. My grandpa checks his health through his watch, but having clothing right over the part of the body that needs examination and getting the i formation real time to transfer for medical treatment would be awesome. Is the technology currently ready to be wireless with those threads in such an application?
I think the way the radio works is cool
This is interesting and neat to learn about
WOW!!!! I LOVE DR. BILLINGS LIVE!!! THE WAY THE TUNED RADIO WORKS IS SO COOL!!! XD
What would i need to make a small simple radio?
this one is the best
Not R-51 with the gold bars, haha!
This video was awesome!
The radio was very cool!
The computer chip in a thread was neat.
i love science live when was the first radio tuned
Can’t wait for Smart Clothes to come out!
This is interesting news.
I wonder how much thought was put for the radios? I LOVE YOU SCIENCE LIVE! 😀
Wow this was a really cool video
I though it was interesting that someone made a computer chip that is shaped like a thread.
the blue monster galaxy is a very cool topic.
thank you Acellus for this science live I loved learning about the different frequencies.
If they pit that little computer in clothes what could it do?
I want a computer shirt.
This is amazing! Blessed to be able to watch these
when was the first radio made??
I think it was by an Italian inventor in 1895
great lesson! hope the next one is just as good!
I always found it interesting when i saw the fisrt radio i wonder how they make such a thing back then
Hey! I was just wondering, what year was the first Science Live?
I didn’t know that is how WIFI was invented/created, how cool!
You guys need a baking class!!
I liked learning about radio and wifi.
Thanks so much for the video the radio fact is very cool!
omg this so cool to learn about
radios are much more complex than they seem.
I love science live
It would be so cool having a phone made of fabric, I wonder all the kinds of things they could make with this thread.
science live is my favorite
who made the first radio?
How did the Blue Monster Galaxy get it’s name?
This was so cool!
I love learning new things from these videos!
How many trials and errors did it take to make the radio.
This is so cool about the radio!
I thoght it would be boring but it was really cool
Listening to Dr John talk about the computers inside or woven into the fabric was sensational to think about. I wouldn’t have imagined that we as a people could think of such revolutionary ideas.
Also loved the tuned radio. 😂
It’s interesting John O’Sullivan’s fail experiment to listen to distorted radio waves from black holes was used years later to help create wifi.
Hello From Mississippi, working without much electricity.
I love science live so much
very good science live today
I use internet with my laptop when I do school.
This is really cool!
The new theory about dark stars seems so exciting!
with the thread computer chip how is it powered
I would love if the radio kit got to be in the Acellus store.
Amazing episode loved the tuned radio, can’t wait for next week.
This episode was really fun!

what are transistors?
How did John Sullivan’s equations help Wi-Fi work?
Dr. Thobias is so funny!
How cool but when is the first rodeo made
I really liked the pirates!
Comment
My mom tells me you can’t believe everything you see on the internet all the time. My smart phone didn’t do so well with the toilet so I definitely won’t try the washing machine. Maybe if it had that new thread technology. Well if fishing line could do that I would be a better fisherman.
i really think this cool cant wait to learn more
HEYYYY FROM CALIFORNIA 🎀😊🤨🦋🥳😀🤩😎
science live is my favorite part of school!!!!!!
I love science lives!
Thanks for making science fun.

Hello, thank you for another amazing video!
My phone has been in the washer before and it was okay
Thank you for letting us be able to watch science live Dr. Billings!!
what was the first radio made from? Was it loud?
What would happen if a radio station tuned on to the wrong frequency? Is it a common thing or does it rarely ever happen? I learned that the first radio transmission was done in the 1870’s. I always thought it was done later.
I really enjoyed the functioning process of the tuned radio!
I love the idea of being able to buy the parts and assemble a radio!
Does the Wi-Fi go through our bodies?
This was a good show.
is that thread water proof?
Great episode, never thought I’d be interested in radios!
