The current daytime site has been the daytime site since 1980 when WAAY went from 5k to 50k. The night time site was distroyed when M.D. Smith the IV bulldosed it and put up a Smith StoreIt there. I worked at WAAY from 1984 to 85 and the 50k signal was massive. Well, they did sometimes run it at 60kw. Originally, they had a four tower array and changed to a three tower one long before I worked there. With four towers, the signal was stronger toward Chattanooga. I've always wondered what that pattern looked like.
When BlackCrow bought 1550 WLOR, the site was in bad shape and only running 1kw daytime only. They had to invest tons into it to get it back to 50kw, cut down all the trees around the towers etc.
