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.

My mom said when she was little the computers where really big. She was surprise to see that the computers are just a string.
How would one even just decide “you know what? Why don’t we just make a computer… but it’s thread” like how do you even come up with that idea in the first place 😮
The pirate skit was so funny! Radios are super interesting to me like how they’ve developed throughout the years.

haha, the start was funny! Great video, very interesting stuff this episode.
So if tuning a radio is basically picking one frequency out of a bunch, how does the radio actually block out all the other stations instead of mixing them together?
my mom said those stats about passing grades made her feel relieved
Enjoyed wednesdays video
