What really struck me as strange is that there seem to be no fewer than
five FCC licenses for stations on 105.3 in California with the calls
KITS-FM.

Do an FM Search on the FCC's website, on 105.3 in California, and you will
see KITS, KITS-FM1, KITS-FM2, KITS-FM3, and KITS-FM4 on 105.3.

KITS is San Francisco, FM1 is Walnut Creek, FM2 is Pleasanton, FM3 is
San Francisco, and FM4 is Antioch. All owned by Infinity...

Can someone explain this? I've never seen it before.

On-channel boosters.
