Here in Wood Dale, IL in the near NW suburb of Chicago:
Daytime: WNDZ with solid signal since March 16, 1987 when they first signed on on this frequency
Nightime: WSB usualy all alone
DX/RETRO: prior to WNDZ taking over the frequency I managed a daytime reception of WRIK (Brookport, IL). I also once heard WSB during daytime during winter. As for the Spanish speaking station it is most likely Caracas, Venezuela, which was heard on many occasions in the past. Back in 1980's Radio Sandino from Managua, Nicaragua was a frequent log. Another foreign station that was heard in the Chicago area was Radio Trujillo from La Ceiba, Honduras. I have 2 Canadians logged on 750, CKGB (Timmins, ON) and CJWW (Saskatoon, SK). On the domestic front the DX includes KSEO (Durant, OK), KMMJ (Grand ISland, NE), KJEL (Lebanon, MO) and WPDX (Clarksburg, WV)
