The Transmitter and studio was in a small green building left of Cow Key Marina (right of the towers and the old Drive in). The AM transmitter (and the old FM transmitter from the 80's) was downstairs along with the AM (WKIZ) FM (WEOW - before it was sold in the 90's). There was also a production room. Upstairs was management sales offices. The FM would 100K in the 80's and the transmitter site and tower was at the landfill (along with 102.5 and 107.9).
On a side note. I do recall that the 60-75 watt STA was on the condition the we did not interfere with WTOP, and I think we did. If that is the case, all towers will need to be proofed and repaired to assume operations which might not be cost effective.
