It carries a mix of classical music and NPR news-talk programming, running a schedule similar to what MPR ran before its 1991 split into a two-channel network.
WGGL attracted a fairly loyal following, although it served a very small market; there were just barely enough listeners for it to be viable as a standalone NPR station.
For some time, MPR still maintained a studio at Michigan Tech's campus in Houghton, producing a few hours per week of local programming.
As of 2021, there is no studio space in Houghton and all programming is fed over satellite or from MPR to the station's transmitter site outside of town.
The station's midday classical music block was cut down to 12 noon to 2 p.m., and new offerings included On Point with Tom Ashbrook, two hours of BBC Newshour, and Talk of the Nation, in addition to the already-running Morning Edition, All Things Considered, Fresh Air, and Marketplace.
