On August 14, 2002, stations KIDO and KFXD exchanged call signs, with AM 580 becoming KIDO, and AM 630 assigned the KFXD call letters by the Federal Communications Commission (FCC). Although for the general listening public this resulted in the two familiar call signs appearing on new dial positions, the FCC generally traces station identities by individual facilities rather than call signs. Thus, it was noted at the time that "As far as the FCC is concerned, this was not a frequency change at all. KIDO on 580 is the same station that used to be KFXD on 580 - the only thing that changed were the call letters. Likewise for KFXD on 630; it is the same station that was KIDO-630."
