Top 40 KIIS-FM has a full time simulcast Class A station licensed to Rosamond, 105.5 KVVS, about 50 miles away. Alternative Rock KYSR has a full time simulcast Class A station licensed to Tehachapi, 103.1 KSRY, about 60 miles away. From what I've read, the only thing these two stations do is play their own legal I.D.s at the top of the hour, which you don't hear on the main stations in Los Angeles. They don't run their own spots for Antelope Valley or High Desert advertisers. It's all Los Angeles commercials.
I know what the theory is. A sliver of Los Angeles County is part of the Antelope Valley and High Desert. Even if it gets KIIS and KYSR an extra .1 or .2 in the Los Angeles ratings, it still helps those stations look good.
About half of KVVS's signal hits Los Angeles County, although the tower is in Kern County. KSRY's tower is even further north in Kern County. Maybe a quarter of KSRY's signal falls on Los Angeles County. I don't know of any other large markets that have simulcast stations so far from the population center, hoping a handful of listeners will boost its main signal's ratings.
