Funny you mention Charleston - 660 is sort of like what 730 WLTQ was like when it was finally donated by then-Clear Channel. A 5kw good daytime signal but very limited at night but better than 660’s daytime only. If I recall they had listeners in Charlotte too.Yup. 660 used to be a powerhouse daytime at 50kw. I’d hear them in the Charleston area as WLFJ. They had listeners in Columbia also.
Forgot to note - 660 and 1440 are diplexed at the original 1440 site behind Ingles at White Horse and Saluda Lake since they built a subdivision on the old WESC site several years ago. One of my favorite radio sites of all time is the 1440 one.
