I was not aware that radio stations did transmitter site tours. It turns out that dozens of these have been videotapes and posted on Youtube. these range from the very historical lecture of the WLW-AM tour to the improvised cellphone video tour of 1230 WBLQ.Ther eis even a 5-part Voice of America Tour with great detail but poor audio.
I embedded a couple of my favorites below
90.7 KKU-FM (great view)
