From East Moline, IL (Quad Cities USA):
Nighttime-
1530: WCKY Cincinnati, OH (before west coast sunset anyway)
1540: mix of KXEL Waterloo, IA and another station, possibly ZNS-1 Nassau, Bahamas
1550: Unsure (mix of stations)
1560: WQEW New York (before west coast sunset anyway)
1570: mix of stations
1580: Formerly CBJ Chicoutimi, QC before it moved to FM only broadcasting. As of the past three years or so, CKDO Oshawa, ON. Mix of other stations is possible on some nights as well. Also, as I stated on the "daytime" thread of 1530-1700 AM, we used to have a local station in Davenport, Iowa, KFQC, on 1580 AM and it originally started out as a daytime-only station but later added a low-power nighttime signal as well. Upon going fulltime, the night signal of KFQC was also audible in my neighborhood along with co-channel interference from CBJ. However, the night signal of KFQC was quite weak. Unfortunately, I can't seem to find any online records of the now-defunct KFQC but my guesses are their daytime signal was anywhere from 250 watts to 1000 watts and the nighttime signal was probably well below 250 watts, thus making it a Class D station in today's radio world. Transmitter was located somewhere in North-Central Davenport.
1590: regional mix
1600: regional mix (KGYM Cedar Rapids, IA nulls its signal to the east (towards me) at night and is harder to hear after dark)
1610: CHHA Toronto, ON or CJWI Montreal, QC (the only licensed stations on this channel in North America)
1620: mix of stations
1630: KCJJ Iowa City, IA
1640: WKSH Sussex, WI (Milwaukee)
1650: KCNZ Cedar Falls, IA
1660: mix of KQWB West Fargo, ND (Fargo) and WQLR Kalamazoo, MI
1670: WTDY Madison, WI
1680: New local TIS station from Iowa DOT (see the "day" thread of 1530-1700 AM)
1690: WVON Berwyn, IL
1700: KBGG Des Moines, IA
