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.

    Learning about how wifi came about is so interesting. I think it’s something I often don’t appreciate enough. I also think it’s very interesting. That new technologies are being made for people who need them specifically it’s something that I really enjoy studying and learning more about. I think this technology could help people who are not able to speak and hear like some of us able to it would be so nice to be able to communicate better. That’s why I love learning about ASL because it helps me communicate with deaf people.
