I made up a star rating system here. RX location is Beecher, IL. 2-story home at about 6ft HAAT. Sangean HDR-1 with small dual-whip dipole on a 4' cable (old RadioShack pocket antenna device for TV+FM). AM is with Sangean's external loop.

I am only listing HD stations for which I get consistent analog reception.
