I worked nights at WBMQ (then WKBX) in the late 70's and early 80's. I can tell you that the nighttime signal used to be awesome. I regularly got calls from as far away as Pensacola, FL and it generally covered from Charleston to Jacksonville. Too bad, but so goes the passage of time.
On a related note, I stopped by the old studio building on Oatland Island a few years ago - my first visit since I left the station in '82. The building is there, but has been abandoned for the move to the mainland. Not much had changed in the way of decor or equipment since I had last seen it 22 years earlier, other than an inch or so of dust that covered everything. It looked eerily like they just got up and left, and abandoned all of the studio equipment in place. I talked to Big Mac (a long time Savannah radio personality) a few weeks ago and he said he and Lyndy Brannon went to the old building to do a story for WSAV -TV on old Savannah radio and found the old building taken over by rats and snakes. Glad I didn't see any when I climbed through the bushes and had my nose pressed on the old, dusty control room window.
