Calgary's big station on 1060, CKMX, left the air last summer, which has left this frequency much more wide open.
KFOY, a Nevada station that goes to just 500 watts at night, is the station I hear most now on 1060. Also, KBGN in Idaho sometimes stays on after dark, even though it's not supposed to.
Whatever conditions made this possible on Wednesday night continue, as I heard KYW again for a few minutes around 0740 UTC last night as well.
