So far I have 530 to 780...
From outside of Duluth, MN, between 2327 and 0000 local time Friday night, using Radio Shack's answer to the GE Superradio...
530 - RVCI (Turks & Caicos, c. 2100 mi!, 100 kW?), weak, vs. another station, presumed CIAO Brampton, ON
540 - CBW (Watrous, SK, 682 mi, 50 kW), very loud
550 - WSAU (Wausau, WI, 186 mi, 20 kW), moderate strength. This station uses more power during the night than it does during day hours.
560 - WEBC, local
570 - WNAX (Yankton, SD, 362 mi, 5 kW), moderate strength, almost no interference
580 - Presumed WKTY (La Crosse, WI, 216 mi, 740w), strong, vs. sth else peaking to NW
590 - Sports, weak, probably KXSP Omaha (419 mi, 5 kW) with others
600 - Country music to W, "After Midnite", KSJB, Jamestown, ND (303 mi, 5 kW) vs. talk
610 - KDAL, local
620 - CKRM (Regina, SK, 614 mi, 10 kW) fairly strong vs. Mike Savage show, almost certainly WTMJ (Milwaukee, WI, 349 mi, 10 kW)
630 - WDGY (Hudson, WI, 134 mi, 2.5 kW) - strong!
640 - Mix of stations, including presumed WOI Ames, IA
650 - WSM (Nashville, TN, 796 mi, 50 kW) vs. something else to the NW (probably fringe station WNMT Nashwauk)
660 - WFAN (New York, NY, 1005 mi, 50 kW), fairly strong, but with bad IBOC hash
670 - WSCR (Chicago, IL, 393 mi, 50 kW), strong but not as strong as usual, possible IBOC noise?
680 - KFEQ (St. Joseph, MO, 495 mi, 5 kW) vs. presumed WOGO (Hallie, WI, 137 mi, 500w) vs. IBOC hash and others
690 - CINF (Montreal, PQ, 894 mi, 50 kW), weak under IBOC hash
700 - WLW (Cincinatti, OH, 650 mi, 50 kW), very strong
710 - WDSM (local)
720 - WGN (Chicago, IL, 390 mi, 50 kW), strong
730 - Mix - Country music, presumed CKDM (Dauphin, MB, 470 mi, 5 kW), French talk, presumed CKAC (Montreal, PQ, 879 mi, 50 kW), vs. talkers
740 - CHWO (Toronto, ON, 645 mi, 50 kW), strong
750 - WSB (Atlanta, GA, 986 mi, 50 kW), weak tonight
760 - WJR (Detroit, MI, 548 mi, 50 kW), strong as usual
770 - WABC (New York, NY, 992 mi, 50 kW), strong, but with IBOC hash
That's all so far. Will do more soon.
