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.

    Radios are fun to use. My aunt has a cool radio app on her phone.
    I also learned about morse code this week. When I was reading a book called My Zombie Goldfish. The characters were using morse code to send secret messages to each other.

    Roger Billings!!!! GUESS WHATTTT me and my father just spent this week piecing together a PC. I noticed alot of the stuff we were learning about with each component reminded me of your science lives. I’ve been listening to you talk about the components of a PC for years, so everything was easier to understand when I was taught how to build a functioning gaming PC. Long story short, I just want to say thank you for this amazing opportunity, AGAINN, its helped me in many ways and I’m appreciative that learning how to build a gaming PC was easier to comprehend because of your lives and your courses. THANK YOUU. You’ve taught me alot. 💞

    One thing I thought was very interesting was in 1874 a boy named guglielmo Marconi was very interested in electronics and physics at this time. Morse code was becoming very popular. Morse code was becoming very popular and in 1894 his mom bought a magazine about Heinrich Hertz and his experiences with circuits in Marconi was very interested. It sparked an idea from Marconi and he decided he was going to make a telegraph with no wires he managed to do so and created the first telegraph with no wires at the age of 21.
    I really enjoyed this video and can’t wait for more.
