Could also be 1600 WKZK out of North Augusta, South Carolina.

They play a black gospel format but will have some preaching and sorts inbetween. They almost never give their call sign but on the hour. They do run local commericials though which can be a tale if this is it or not.

I get them or WWRL out of New York on 1600 here. But I live in Leesville, SC which only puts me 35 miles from the WKZK transmitter.
