K-FROG can't be thrilled with the change, especially since they've claimed they are upgrading their signal into Orange County (read spent $$$). BUT they were NEVER considered by advertisers to be anything other than a station serving the Inland Empire.
Despite being mentioned here, I see no recent modifications or CPs
EDIT: I just looked at the coverage maps from Radio-Locator and they're almost identical. The two signals 93.9 and 105.1 have around the same power, too (18kw).
KMZT´s antenna is much closer to the ground on Wilson, resulting in some considerable shadowing. KZLA is the bbetter signal
