40 Miles northwest of downtown Chicago....
Days: Usually blank. Sometimes a whiff of WVCY from Oshkosh, WI (between Milwaukee and Green Bay). Only 250 watts, but aimed in my direction. Even so, my location is normally just out of range.
Nights: Up until about six months ago, 690 was usually a weak WQNO from New Orleans. For about the last several months, however, they've been missing. The channel subsequently has been pretty quietat night. Although CKGM sometimes sneaks in. (The CKGM call letters have been at various frequencies around the Montreal radio dial down through the years. My last memory of them was on 990 with oldies,)
Retro/Other location: 690 has been home to some legendary top 40 stations. WAPE, WVOK, and most notably (for me), WTIX, WVOK (Birmingham) sometimes made it in here to the Chicago area before signoff at sunset. WTIX was rare here, but occasionally doable. I never heard WAPE here at home.
CBF from Montreal dominated the channel at night, (CBF was 50kw non-directional. The current incarnation of CKGM is 50kw, but with a major mull to the east and south).
Meanwhile, here at home, KGGF from Coffeyville, KS used to be common around sunset on day power/pattern. But it's been quite a few years since I;ve heard them.
At our beach location near Pensacola, WQNO does quite well with a good day signal at 9,100watts ND. Comparable signal to what WTIX was, Night is a different story. WQNO's night signal is 1kw directed mostly east-west. WTIX had a similar night pattern, but at 5kw. WQNO is 2,1 at night and the difference is very noticeable. R. Progreso from Cuba trashes WQNO.
E, WVOK, and most notably for me
