en Northern Star Broadcasting

Northern Star Broadcasting (formerly known as Calibre Communications) was a radio broadcasting company which owned various radio stations in Michigan from 1998–2016, with offices in Cheboygan and Traverse City.^[1] Northern Star was owned by Reynolds Communications, ran by Del & Mary Reynolds.

At one time or another, Northern Star Broadcasting owned eleven stations in Northern Michigan (nine as of 2016) and previously fourteen additional stations in Michigan's Upper Peninsula, exiting Upper Peninsula markets in 2010 & 2011 after selling all but one repeater station to new owners, largely Sovereign Communications of Sault Ste. Marie, Michigan in February 2010.^[2] Despite the sales, Northern Star's stations in Cheboygan, Mackinaw City, and Indian River could still be heard in much of the Eastern Upper Peninsula.

In May 2016, and due to Northern Star vice president Mary Reynolds' health concerns, Reynolds Communications announced the sale of all but one of Northern Star's remaining radio stations to Black Diamond Broadcast Holdings (who previously owned WUPS in Harrison and WTWS in Houghton Lake) in a transaction worth $1,950,000, with WCKC in Cadillac instead being sold to Up North Radio (who own WCDY in McBain) for $180,000. Despite the sales of their remaining radio stations, Reynolds Communications will retain ownership of these stations' tower sites.^[3]
