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.

very interesting SL, love learning about radios.
The science live is very informative!
So cool how they made their own radio! Might make one for myself… 🙂
Hehe I love the butterflies! R51 is R51 XD
Thanks for the Live! This was another good one. 🙂
this is very cool to learn!!
I really enjoyed learning about the radios and “computer threads”
yeah when was the very very first radio made I wonder? 🤔
I like the idea of adding the radio to the gold store. I say do it!
Y’all are so funny thank you for everything thank you
In the live it talked about a computer thread wire in a computer and the thread wire was on the computer. So then it also talked about a thread being in a computer and the thread being in the computer on.
I find it cool what they called WI FI before they named it WI FI.
I got snow here! I loved sitting cozy inside while watching science live.
I would like to have that kit in the store
This is so interesting cant wait for next weeks!!
I’ve never enjoyed a Science Live so much!
im going to trying my a radio. This was very interesting.
Thank you so much for sharing!!
It’s really interesting how Wi-Fi was originally I triple e 802.11 and how there was really no explanation for the name that they chose.
I still use my radio to listen to music and sports games
Radios are amazing
A “do-it-yourself” radio kit sounds like a fun project!! 🙂
I look forward to science live
i like the wi-fi part.
Yes I want to build it (the radio)
Thanks for a great lesson
I didn’t know that wifi worked like that!
Dr. Tobias, do you think the scientist in Australia could have made his black hole technology better with Wi-Fi?
I like the computer line thing.
Communication and entertainment is always going to continue to grow. Look how far it’s come since our grandparents were teenagers? Back then they only had newspapers and telegraphs. Then came the landline and radio. Now we have the Internet an instant messaging. Thankful to all the inventors who help us communicate and listen to music today.
This video was awesome!
Wow! The radio is so cool and I think it would be fun to make one. Y’all should definitely add it to the store.
It was so funny when he said “Inventioneers, assemble!!!” then he got sunglasses XD. And so unexpected the Wellerman sea shanty
Dr. Billings, can there be other stations on the R51 radio box, so we can listen to actual radio?
Its cool how much technology has up graded. Whats also cool is how they ran the cord over with a truck and they were still able to use it.
I thought it was cool that a thread has computer chips on it and can be used on new computers.
I can’t imagine what we could make with that micro chip string stuff
Always love learning new stuff from these Awesome videos. Thank you for always making these so interesting and I always Learn something new
Thank Acellus. Never knew how the radio was made.
Never knew how radio was created. Thanks Acellus.
Science just keeps getting better and better. I wonder how the next generation will listen to music and talk radio?
Science live is the best thing out of the school year so far I love it 🙂
It’s crazy how smart some people are, how do they come up with that stuff!
Tobias’s jokes lol. watching from SC!!
Hi from Buffalo NY!
Science Live is so cool!
I believe thats how science should be. We learn more and more as we go. Science should continue to get more and more in-depth as we develop better and better technology. So radio was huge back then, but now we have wifi and satellite.
I find it cool that WI FI had a lot of problems when it first came out.
I think it was cool to see them make a homemade radio.
Cool never thought that radios were so complicated hahah
That computer thread is awesome. I need a shirt made with that.
How did humans even discover radio waves if they aren’t visible?
The amount of time scientists fail at their experiments and keep going like Marcony shows that they are more determined than most people to keep going after their dreams. The cable breaking in the ocean and his first tower being destroyed by a storm and still going is a great story of perseverance.
Watching from ohio
When was the first radio made?
1895! By Guglielmo Marconi
The first radio was made in 1895 by Guglielmo Marconi . Although in 1893 Nikola Tesla demonstrated the first wireless transmission.
This is so cool! I love science live
Science live is so cool!
Tuned radios are so cool! I love science live
I love this episode! My mom use to use radios all the time!
I love Acellus
The first radio was made in 1895.
thank you 😊 ❤️
The tuned raiding is a very cool subject. I love live lessons!
yay I love these
How expensive would “smart clothing” be?
i love listening to the radio
I think that its cool that computers can be in our clothes
Me too they are so fun
I think the way the tuned radio works is very interesting.
that is cool when was the first school built.
that’s cool how that the spark appeared on the second ring with a gap after the circuit produced the spark
Ok I love this
Can’t wait for next weeks live!
me toooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This episode was amazing!
I loved this episode.
Thank you for making Acellus.
LOVEEE THE SCIENCE LIVEEE
Wow having a brain technology implant would really help a lot of people would it be a chip and implanted during surgery? Some people really go above and beyond to study things learning more about the black holes would be interesting yet scary because you have to go to space. Yes wifi has really changed over the years.
Agreed, it helped me larn so much!
I liked learning about the computer threads and all of their potential uses.
Wow making transistors really small could really help make a lot of things. Computer processes are going to get a lot more interesting now that’s really cool.
This is so fun
I love Dr Billings
I thought it was amazing!
So excited to watch Science Live this week !!! The Acellus team is amazing !!! Best program ever !!!
Awesome video!! The amount of things we can’t see, but matter, is astounding!
I love these science lives they are always so interesting!
I love acellus it’s so diff
Thanks Acellus!
I like when the person unboxed the toilet paper holder, and when they built the radio, and when they sing
I love Dr Billings 🙂
I think that it would be very useful to have actual smart fishing line
who created that thread?
How loud would the tuned radio be?
r 51 is so funny 🙂
thanks for the science live
loving it, cant wait for next Wednesdays science live.
I feel everyone should know about the different tuned radios
I love science live

i love science
the singing was my favorite bit I think we need to hear more of it pleaseeeee
Cool. Radios to Wi-Fi.
Are any of you guys going to acellus world this year I might be going please reply back to me and maybe we can become friends
Dr. Tobias, that’s funny; nowadays we get frustrated if a page for program doesn’t load within seconds.
Its crazy how much telephones have changed since the first device!
Dr. John, could you put a computer game on your clothes so you could play games anytime, anywhere?
i love sience live computers are awsome i build a pc
It’s incredible that computers have tubes inside of them.😁
I learn new things every week! Thank you
Black holes are intresting and scary at the same time.
David and Caleb are so funny! I want to see more of them in future Science Lives.
The pirate scenes were my favorite.
Black holes are intresting and scary at the same time

I never knew how the radio was created. So cool!
I love science live. I hope they do one on trains.
This was easier for me to understand than last week. I liked it!
cant wait to have led clothes!
acellus has truly saved my academic career
that’s so amazing!!! I want to learn more about that :>
Dr. Billings, 100%…I want to earn that radio, so I can listen to all R51 channels! 😂
Love this as always 💕
Acellus is so awesome
Happy to be here today.
Supper cool coming from Chicago
Dr. Tobias, do you think the scientist in Australia could have made his black hole technology better with Wi-Fi?
I love warching these, I look forward to it every week! And I love reading coments.
radio waves were so amazing.
Would love to have a radio kit!
Computer thread is blowing our minds here!
Dr. John, it’s strange, but I always wanted an LED shirt…and it’s almost come true. 😂
LOVE SCIENCE LIVE❤️❤️❤️!!! Hope to see more videos like this one.
Great science live! From Wisconsin.
hello from Columbia, MO!
My favorite part of science live is the technology spotlight with Dr. John. Talking from Mississippi
I love r51 he is so funny’
I didn’t know that WI-FI had so many problems when it first came out.
That was amazing! I loved learning about Marconi, and how to tune a radio! Would David and Caleb be able to do a demonstration on how to build a radio from scratch using household objects?
What would the purpose of smart clothes even be since we already have smartphones?
I also really liked the jokes Mr Tobias said
I am really enjoying the Science Lives. Thank you
thank you for the science lab today I enjoyed it!
Hello, from Alabama! Radios are so interesting😋
i like watching science live
watching from georgia
r 51 actually has a sense of humor, very cool
I am really excited about the pilots course. I really hope you can get it done by June so I can take it before graduation. Please hurry!
Oh! Congratulations! Your gonna be graduating😁
Hello from FL!
Loved this week’s Science Live, good work Acellus team
It’s very interesting how wifi was made and perfected. I love how Tobias kept saying right with that accent.
Thank you guys so much for taking your time to make this Science Live, I love learning new things about everything.
Hello! I really enjoyed this episode!
great episode love these they get better and better so cool
Science live is cool
This was a good episode!! Thank you science live
If we complete the aviation course are we ready for in air lessons?
A computer in a thread is really cool.
The Morse code is cool.
The proteges and the ventioneers are very funny.
the creation of WIFI turned out to be very useful over the years.
Its impressive how they manufacture such small things like that electronics cable.
Love these every week!
Having a computer on your shirt is crazy!!
I hope we have the ability to make a matrix soon, so every person can have their own personal matrix without interfering with each other
We can’t make portals bro
I love this science live
Another very interesting episode. I really enjoyed it, thank you!
Where would the radios be manufactured?
I think they might be manufactured on the Acellus store platform where you buy with your gold coins.
I wonder if the worlds technology we know disappeared over night if we’d be able to recreate what already was invented perhaps better or a different variation of it.
Science live teaches me about so much. Thank you for helping me
Thank you for this week’s science live!
I love this!!!
I like the Abraham Lincoln quote about the internet.Very funny
This is an amazing video.
The science live is always incredible. Can’t wait to see more kids from all around the world join this program.
I learned so much about radio waves, thank you science Live.
This is very interseting, and fun to watch!
It’s funny how we use technology everyday and don’t consider how it works.
Thanks for sharing the interesting information
The possibilities of having a computer processor in such a compact form could serve very useful in the near future. I also find it really cool that the Wi-Fi we all use today is made from black hole technology.
science live is awesome
This live was amazing!
Hello from South Carolina
Hello from Texas, Thanks.
Very interesting episode of Science live!
Wow a whole computer in a thread is so cool!
Wow! This science live was super facinating! r-51 was funny to!.. as always. 🙂
