operates two translators, mainly to provide clear service of the station to lakeshore cities with varying terrain blocking reception of the main signal, and to address interference in farther portions of the market by former sister station WGN-TV from Chicago, which also broadcasts its digital signal on UHF channel 19. Two additional transmitters in the southern part of the market, officially classed as WXMI digital repeaters, serve the direct Kalamazoo area on channel 30 from the tower of WGVU-TV's Kalamazoo satellite WGVK, along with a second repeater licensed to Battle Creek on channel 17 transmitting from the city's south side; all four translators carry WXMI and its subchannel services, and all map via PSIP to channel 17. As of 2021, WXSP-CD also carries 17.1 in the ATSC 3.0 format. This means it is possible for a television or receiver in the Grand Rapids market receiving an over-the-air signal to map out up to six different WXMI signals in its channel map. W42CB channel 42 completed a flash-cut to digital-only broadcasting in November 2010. W52DB on analog channel 52 was replaced by a digital signal on channel 17 in December 2010. In late June 2011, W52DB calls became W17DF-D. In mid-March, 2019, W17DF-D moved from channel 17 to channel 18. References WXMI TV Channel 17 (June 13, 2005). Michigan's Radio and TV Broadcast Guide.
