Wow. Kolorful KOL's mighty transmitter once hummed and crackled from a ship cocked over there, but did you know Fisher Communications once had its flour mills on Harbor Island? (Bet they wish they had a few flour mills to fall back on at the moment) Check that out at HistoryLink.
Here are more arcana from one of our favorite radio sites: Jose Fritz's Arcane Radio Trivia:
In the 90’s, the Port began expanding their shipping operations as they "containerized" the port. This expansion on Harbor Island encroached on and eventually occupied by the transmitter and tower facilities. In the summer of 2001, the Port came to an agreement with KKOL to abandon the Harbor Island transmitter facility hence the Coastal Ranger install... It was to be temporary, An application was filed with the FCC for a new 50,000 Watt replacement facility about 15 miles south of the Harbor Island site. In 2003 a pier fire nearly took them out again.
