 At that time WGPA-FM used a sub-carrier to broadcast instrumental beautiful music from reel-to-reel tapes for playing over paging systems inside retail businesses.Eventually, that same beautiful music sound was airing on WGPA-FM.In 1973, when WGPA-AM and FM were sold by the Globe-Times to Holt Broadcasting, the new owners changed the FM call sign to WEZV, to reflect the FM's easy listening radio format, with the EZ in the call letters standing for "Easy" and the V representing "Valley" as in Lehigh Valley.
