Very interesting signal indeed. I watched it on my scope until it
disappeared right on the dot of 1:00 AM CST.
Just went off of as if someone flicked a switch. Over three hours it
slowly drifted up and then down in frequency several megahertz from
what seems to be the center at 229.560.
It recently came back on again at 10:00 CDT AM on 229.5465 MHz and
is drifting slowly up the band again.
