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 really liked when it talked about all the radio waved being sent and received. I especially liked when it talked about how you can’t believe everything you see on the internet!!
I think it’s amazing that a computer can fit in a strip!
I think it’d be cool to have a R-51 radio and you could have a choice whether you want it pre-made or you want to construct it yourself.
Is it going to be possible to use those thread computer to create better health measurements for medical patients?
Very interesting video!!!!!

Thank you for the scholarship!
My grandfather gave me his old radio and every now and then I turn it on and try to find a station that broadcasts music. Sometimes it’s hard to understand the stations and stuff because it’s so old, but it comes in handy for weather emergencies which is good.
That’s so cool having computer by a thread.
I’m going to make a foxhole radio
A computer in a string is absolutely crazy!! Also, I am so excited for the new course!! Please, put the R51 project in the Gold Store. Thank you for such a fun video!!
