This frequency is a black hole for me here in MI. Nothing to hear day or night. Of the 40 or so stations on this freq, none are in MI or the neighboring states of OH, IN, IL.
Looks like all the stations on 900 go to 500 wats or less (mostly a lot less) at night. Will keep an eye (ear) on this freq as the Winter nighttime skip season develops...
who knows, something may pop up.
