On February 28, 2003, the callsign was changed to KCDU, which flipped to Hot AC, and re-branded itself as "101.7 The Beach" with the slogan being "The Best Mix of the 80's, 90's and Today."

The station also began running the syndicated James McPhee Dream Doctor and John Tesh shows.

In the Fall of 2011, KCDU began transitioning to CHR, first by adopting its current slogan, then cutting out all of the 70s, 80s, and 90s music it had broadcast for years.

The Beach also moved its syndicated John Tesh Morning show to the new sister station B103.9FM (formerly Classical KBach).

On July 1, 2019, Mapleton Communications announced its intent to sell its remaining 37 stations to Stephens Media Group, marking its entry into California.
