WRAL and WRAZ will not grant you a waiver...period. They are independently owned by Capital Broadcasting, thus not held to the agreements that D* has with stations owned by the networks. Granting waivers simply isn't their best interest, as it reduces their negotiating power and takes advertising revenue out of their pockets.
That said, they both generate the absolute best local HD signal and you should have no troubel locking in on them with a decent OTA. You will be happier anyway as the OTA picture is noticably better than D*'s compressed signal.
I tried to ask the D CSR if this was a waist of time or not. She kept on stating we had to go the waiver route. I asked her if anyone has been granted a waiver from WRAL/WRAZ and she wouldn't answer the question.
I'll wait and catch up with these girls on HDNet
