The departure is part of restructuring at Journal Broadcast Group of Boise's radio stations, according to vice president and general manager Marie McGlynn.
Some of Mac's duties will be handled by recently hired radio station manager/general sales manager Roy Williams. Others — including the 3 p.m. to 7 p.m. weekday "afternoon drive" slot — have been taken over by Variety Rock 105.1 FM program director Jim Allen.
Mac has been a staple for around a decade at K-Hits. He has worked at other Treasure Valley stations including KFXD-AM, KGEM-AM and KQFC-FM. His voice is instantly recognizable to fans of Boise State basketball. He's the P.A. announcer at games, where he's known for a signature traveling-violation proclamation: "Wwwwwwaaaaaaallllllking."
Mac was unavailable for comment. His phone number is not accepting calls.
