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 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.
