It was far from a legendary brand in Seattle. It occupied what is the 106.9 dial position, then as now licensed to Bremerton WA. At that time it was transmitted from a tower on Gold Mt., which served areas near Puget Sound quite well but did not get into prime areas away from the water so much. KHIT entered an already overcrowded Top 40 field in lat 1984 that included KUBE, KPLZ, KNBQ, KRKO AM, KTAC AM, KJR AM, KING AM at least. They did not prosper under this format, and eventually jumped aboard the next big thing (New Age music) as KNUA in 1987. It is now KRWM (the worm.) If my memeory serves, and it doesn't always, this station was originally KBRO, then KWWA, then KHIT, then KNUA, then KKNW, then finally KRWM.
Now I actually worked for the original KHIT in 1984 (in Walla Walla, WA) and was working there when our strapped owner sold those calls for $35,000. Our PD was none too thrilled to lose 40 year old heritage calls one day. We became KAFR (America's Fun Radio)- just awful calls back when those meant something. Multiple ownerships later, and that station now houses some legendary Seattle calls, KXRX.
