Does anyone know where WKRP was on the AM dial?

1530 AM

I don't mean to offend those who don't like old threads resurrected, but I thought it worthy to chime in when one of my coworkers, a WKRP fan, was wearing a shirt with the WKRP logo and the 1530 frequency. (I found this thread by entering the number 1530 into the search thread option, by the way, since I was unsure whether the frequency was ever discussed on this thread.)
