When you turn the dial to WAMU 88.5, you soon might not recognize the programming. D.C.’s local public radio affiliate is making some big changes.

Starting next year, The Kojo Nnamdi Show will halve its run time from two hours to one, airing from noon to 1 p.m. only. In a blog post penned by the host, Nnamdi frames the change as a good one. “The new one-hour Kojo Nnamdi Show will allow me and my production team to focus on what we do best: convening discussion on critical regional issues,” he writes.

The second hour of the show currently focuses on national issues, and according to Nnamdi, “WAMU is carefully considering options to air a national show that will enhance the station’s schedule.” The change takes place on January 25.

Nnamdi’s post says that the noon Politics Hour on Fridays will remain in place.

Afternoons aren’t the only time of day to see a shift. Host Diane Rehm, whose two-hour newsmagazine program is recorded at WAMU and syndicated across the country, will retire next year, The Post reports.

The 79-year-old’s show has run for nearly 40 years, and folks at WAMU told the Post that she will probably step down after the presidential election.

Plus, the Friday show Metro Connection is currently on hiatus. A post on WAMU says that, “The show is taking a break, while we rethink how to deliver the highest-quality sound-rich stories to your ears and eyes.”

And many of us already miss the friendly sound of traffic reporter Jerry Edwards, whose reports ended on November 13 amidst changes to morning programming.
