WKZO (590 kHz) is a commercial AM radio station in Kalamazoo, Michigan. It is owned by Midwest Communications, Inc., and airs a talk radio format. The studios and offices are on West Main Street in Kalamazoo. WKZO's transmitter is a four-tower array on McKinley Street at 21st Street North in Cooper Township, Michigan. The station operates at 5,000 watts, using a non-directional antenna by day. Due to its location near the bottom of the AM dial, as well as its transmitter power and West Michigan's mostly flat land (with near-perfect ground conductivity), its daytime signal reaches much of the southwestern Lower Peninsula, with Grade B coverage as far east as Lansing, as far south as South Bend and as far north as Mount Pleasant. But at night, to protect other stations on AM 590, WKZO switches to a directional antenna, with power fed to all four towers. Much of the nighttime signal is directed north, concentrating it in the Kalamazoo and Grand Rapids areas. WKZO programming is also on a 200-watt FM translator, 106.9 W295CL, heard in Kalamazoo and adjacent communities. Programming Since late December 2021, weekday mornings have begun with an hour of America in The Morning at 5:00, followed by a four-hour morning show hosted by Ken Lanphear. Late mornings feature "Michigan's Big Show" with Michael Patrick Shiels. The rest of the schedule is made up of nationally syndicated shows, including The Dan Bongino Show live from noon to 3 p.m.; Markley, Van Camp & Robbins; The Mark Levin Show live from 6 to 9 p.m.; The Ben Shapiro Show; and Coast to Coast AM with George Noory. Weekends include shows on money, health, real estate, law, auto repair, home repair, travel, gardening and bird watching. Some shows are paid brokered programming. Weekend syndicated hosts include Clark Howard, Kim Komando and Bill Handel. WKZO is also part of the Michigan News Network and carries world and national news from CBS Radio News.
