 Cincinnati Public Radio was not interested in retaining ownership of WVXU's "repeater" stations outside Ohio and sold the station to Midwestern in March 2006.After the sale was closed the following May, its call letters were changed to WRGZ and it began repeating WATZ.WRGZ allows WATZ's programming to be heard in areas where the 99.3 FM signal is not heard clearly, as far north as Cheboygan and into the eastern Upper Peninsula.
