If I recall, there were some articles at the end of last year written about how CBS wanted the radio and TV sides to have more "synergy" having personalities show up on both platforms, cross promotion, etc. At the time the CFO of CBS Radio was promoted to COO of CBS Local Media, overseeing both CBS local TV and radio.
Here, we do see the KTVT weather folks do weather on KRLD.
However, CBS-owned KRLD-FM has a mid-morning show hosted by the NBC O&O KXAS sports anchor. Various KRLD-FM hosts seem to appear on KXAS' Sunday night program and not on KTVT's. Last week, KTVT's sports anchor was on as a guest during Norm's AM drive show on KTCK while the Musers were away (and Babe even mentioned "when I was listening yesterday to the show..." indicating he listens to KTCK and not sibling KRLD-FM).
It's kind of curious there is a total separation between KTVT and KRLD-FM
