Yep. And two of those are Jacksonville. 600 and 690. The locals are 730, 910, 950, 1250, 1340, 1390, and 1450.
Three other stations are either off-air or much weaker (810, 980, 1480). Only 950 and 1250 don’t have an FM translator paired with it.
Charleston is one of the worst AM markets in the nation. Maybe 2-3% of the radio listenership goes to AM now. And most of it goes to 1250 WTMA.
