Back when KXA was the home of "Old Gold 77", it wouldn't last much longer... from Wikipedia
Formerly, the station had the callsign KXA and had a classical music format. It was in a big battle with KING-FM 98.1 and KUOW-FM 94.9, which both on FM were doing the same format. In the late 1970s and early 1980s, the station aired an oldies format and was known as "Old Gold 77 KXA". The station dumped oldies and flipped to a simulcast of country station KRPM-FM (now KBKS-FM) and changed call letters to KRPM. The station would change call letters to KULL in 1991, but maintained the country format. In a format swap in 1995 with AM 1090, the station received the call letters KNWX and the talk format. The station would acquire the current call letters KTTH in 2003.
