History
WRTH-LP first went on the air as WEZG-LP on July 2, 2014, with a 24-hour mix of songs with "Abigail" as the subject matter. The station frequency, studios and operation were developed by Dave Solomon, a veteran of the radio business since 1979; having owned other radio stations and achieved ratings success as a program director & operations manager throughout the Carolinas (Greensboro, Raleigh, Myrtle Beach & others) for large radio groups like Clear Channel, Entercom, Cumulus and more. Solomon also was one of the creators and sole voice over talent for the SaveNetRadio Music Licensing Campaign, regarding licensing fees paid to SoundExchange, a performance rights organization. His political ads were broadcast on thousands of radio stations coast to coast and quoted in numerous national media. The Copyright Review Board proposed a huge rate increase, SaveNetRadio was victorious via Congress, in the passage of the Internet Radio Equality Act in July 2007. He also serves as the executive director for the Washington, DC advocacy group Low Power FM Advocacy Group (LPFM-FM), who files to protect the licensees of LPFM stations through multiple protective filing at the FCC.
