Well, now wait a second, guys.
I see everyone's point here. But according to the FCC, the Tennessee station is WKRP-LP, while we have WKRP-TV. It's my understanding of the issue that they're separate classes.
I know some of you point to call letter confusion. Look at Dallas which has KDFW (started as CBS, now Fox), KDFI (had been indy since '81 as KTWS - changed to KDFI in '83, bought by Fox in '95), and KFWD (originally Telemundo in the 90s, indy since 2002). I never heard a complaint about the call letters there.
