For this week's Overdrive Radio podcast, Mark Karnes tells the story behind the Cobra company's petition to the Federal Communications Commission some years back to allow the use of FM rather than just standard AM in CB Radios. With the petition granted in 2021, Cobra is now out with AM/FM dual-mode versions of all of its most-commonly-used models, joining some other makers, too.
Karnes, a vice president with Cedar Electronics, Cobra's parent company, notes the transition from AM-only radios to dual modes won't happen overnight. When more FM-capable radios are in play, though, he said, users will find better voice clarity over the air when used in FM mode on both ends.
