KAJM-FM (Sunny 104.3) Phoenix

Sierra H Multimedia has launched Sunny 104.3 in Phoenix, flipping Urban-formatted KAJM-FM (Mega 104.3) to a Soft AC format branded as "Relaxing Favorites." Effective immediately, Sunny 104.3 replaces the former Mega 104.3, introducing a mix of pop and AC hits spanning four decades. The station is targeting at-work listeners with a presentation centered on familiar songs and an upbeat, feel-good approach.

The playlist includes artists such as Adele, Celine Dion, Michael Bolton, Bruno Mars, Whitney Houston, Phil Collins, Ed Sheeran, Elton John, Chicago and Air Supply.

As part of the format change, the Mega 104.3 brand has moved to 99.3 FM. Sierra H Multimedia said the station will continue its existing programming and on-air personalities at the new dial position.

"It's a Sunny day, and we're proud to introduce a new destination for at-work listening and Relaxing Favorites for the Valley of the Sun," said Content Director Eric Rosado. He described the station as filling a gap in the market with familiar hits presented in a "Soft Adult Contemporary" format designed to resonate with Phoenix listeners.

Sierra H Multimedia Owner Ken Brentlinger said the launch expands the company's portfolio to three stations and adds what he called a proven format aimed at both listeners and advertisers.

Sunny 104.3 is now available across the Phoenix metro area on 104.3 FM, while Mega 104.3 can be heard on 99.3 FM.
