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.
