The last time I was in Portland (2012), 102.5 was a weak signal from K273AJ Elwood (Molalla area), with KAWZ/CSN programming. KZOK did make it on the last day I was in Portland, on the 3rd floor of the Gresham Hampton Inn. Tropo conditions were up, as I even heard KISM 92.9.
Here in Ellensburg, 102.5 is usually nothing, but a new translator has popped on in Selah (K273DK, // KTCR-980) that I get occasionally driving on Vantage Hwy...when the car's antenna actually works the way I want it to. 102.5 Selah is a waste of a channel, as 106.9 serves that area just fine. Maybe Stephens Media will eventually flip 106.9 to another format, as it is relayed from one of KHHK's HD subchannels. Yakima needs an Adult Contemporary station - or classic country.
KZOK Seattle and KRAO Colfax have been heard via tropo or scatter.
