TWiRT 824 - Silicon Carbide: AM’s New Horsepower
Friday, October 30, 2026 at 8:14AM
What happens when transistor technology proven in electric vehicles finds a new home in an AM transmitter? You get a fresh approach to making RF power—with less wasted energy, less heat, and a remarkably smaller footprint.
On this episode of This Week in Radio Tech, Rich Redmond, President and CEO of Broadcast Electronics, and Tim Hardy, Senior RF Engineer, join us to explore the silicon carbide MOSFET technology behind BE’s new AMX transmitter series.
But the conversation goes well beyond the transistors. Rich shares what he saw in Broadcast Electronics that inspired him to become an owner. And we explore the partnership behind a dependable product: What does an engineer need from his CEO to do his best work—and what does the CEO need from the engineer to turn a promising design into equipment broadcasters can trust?
We also look at the possibilities for putting more of the transmitter site inside the transmitter itself: audio processing, HLS stream reception, a built-in receiver with streaming for remote listening, and potentially software-based EAS as FCC rules permit. Rich discusses how this approach could extend across AM and forthcoming FM products, reducing the space, equipment, and heat load needed to keep a station on the air.
Join us for a conversation about better transmitters, thoughtful engineering, and the people helping shape the next chapter of Broadcast Electronics—on This Week in Radio Tech!
