Here in Wood Dale, IL in the near NW suburb of Chicago:
Daytime: local TIS's from Palatine, Skokie or Lisle are possible at my location depending on the loop antenna orientation.
Nighttime: WTOU most likely
DX/RETRO: WJDM used to rule the frequency. They are now WWRU, but not longer very common. KXTR (Kansas City, KS) used to be an interesting catch with classical music programming before switching to sports and changing calls to KWOD. Also heard KXOL (Brigham City, UT), KRZI (ex-KAXY - Waco, TX), WFNA (Charlotte, NC). WMIB (Marco Island, FL) logged thanks to a specially arranged DX test in 2001, but also heard with new calls WCNZ. In 1999 WD2X experimental station in Cincinnati, OH was received in the Chicago area. Have been trying for WGIT Casanovas, Puerto Rico, but no luck yet. Another target is KBRE Merced, CA but it's probably not very likely to be heard in Chicago area.
