From south Overland Park, Kansas:
Day: A very weak KSIS - 1 kW non-directional in Sedalia, Missouri.
Critical Hours: KSIS, KLOH - 9.38 kW 2-tower directional in Pipestone, Minnesota, KGTO - 1 kW non-directional in Tulsa, Oklahoma, WDZ - 1 kW non-directional in Decatur, Illinois.
Night: 100 kW XEG in Monterey, Mexico can dominate at times or completely disappear. They are often at their strongest in the 2.0 hours right before morning critical hours. My real "prize log" at night was WLIP - 250 w non-directional in Kenosha, Wisconsin earlier this summer at 4:30am CDT, just before critical hours.. About 60-70% of the time 1050 kHz sounds like a "graveyard channel" at night from my location.
