From East Moline, IL (Quad Cities USA):
Nighttime-
1320: Regional mess (WKBF bleed possible if skywave conditions are poor or nonexistent)
1330: KWLO Waterloo, IA mixed in heavily with other stations
1340: severe graveyard mess. I can occasionally still hear KROS Clinton, IA on top but just barely
1350: regional mess
1360: regional mess
1370: regional mess (KDTH Dubuque, IA nulls its signal towards me at night; is aimed north of DBQ instead)
1380: regional mess (KCII Washington, IA powers down quite a bit at night)
1390: regional mess (KCLN Clinton, IA still comes in on occasion; though it powers down to 91 watts at night)
1400: severe graveyard mess with WOC bleed under
1410: regional mess under WOC splatter
1420: WOC Davenport, IA (local)
1430: mix of unidentified stations under WOC splatter
1440: mix of unidentified stations with WOC bleed underneath
1450: severe graveyard mess
1460: mix of unidentified stations
1470: WMBD Peoria, IL and KWSL Sioux City, IA with an occasional appearance from KWAY Waverly, IA (in the event that the last one forgets to "power down" after sunset)
1480: mix of unidentified stations
1490: severe graveyard mess
1500: KSTP St. Paul, MN
1510: WLAC Nashville, TN (not nearly as strong as their I-A clear-channel counterpart from the Grand Ol' Opry on 650 kHz)
1520: Unsure (will need to look for KOKC (formerly KOMA) Oklahoma City, OK someday) Considering the deep null that WWKB Buffalo, NY throws out, I guess I can pretty much forget that one.
Note: WLAC on 1510 AM is a I-B clear-channel, shared with KGA Spokane, WA. WSM is a I-A clear channel which was once the only 650 on the AM dial at night and is now shared only with an Alaska clear (KENI Anchorage; a I-N clear-channel station) and many smaller stations with smaller signals like WNMT Nashwauk, MN and KGAB Orchard Valley, WY; both of which are well beyond 750 air miles from WSM; thus allowing them nighttime operation as well.
