Sounds like you're in the same "place" I was in a couple weeks ago, setting up my FTA system. I'm at 84.19 W in Ohio, probably not too far from your longitude in Michigan. So I wanted to use AMC9 too but there wasn't much if anything on it then (I've since seen the NBC thing myself but couldn't tell you if it was on then).
I ended up using AMC-3 at 87 W. If you're setting up a motor, first get the motor pointing true south at its reference position (0 degrees). Then select AMC-3 in the Antenna Setup screen and move down to "Positioner Setting" and set it to USALS. Press OK and enter your exact coordinates. The 87 for AMC-3 should be left alone (only tweak that as a last resort once you get some kind of quality signal). Select "move", then "store" the location (last menu item) and exit to the previous screen. Move through the available transponders until you get one that looks busy on lyngsat (or verified from somebody here). Now you may have to tweak the dish/lnb to get some quality reading.
If not setting up a motor, then just point the dish at AMC-3's true azimuth from your spot and ignore the USALS stuff above.
