One FM frequency I never did either.
102.1 in Yakima is a strong KPQ Wenatchee, WA. Operates on Mission Ridge with 35KW and has a classic rock format. "The Quake". I've heard them everywhere, as far west as Hoodsport on the Olympic Peninsula, and used to also hear them in Seattle a lot.
In Seattle, I also used to hear KSWW Montesano (now Ocean Shores) WA with AC music. "Sunny 102.1".
Stations caught via E-Skip on this frequency. KPQ is tough to null when I am working skip, but I have heard bits of skip pulling through during big openings in Yakima. The 3 logs were all made in the Seattle area, where 102.1 is a lot more open.
KTRA Farmington, NM (7/29/2007 from Seattle WA - Country, actually my first skip catch ever. And on accident - was looking for KSWW)
KPRI San Diego, CA (7/8/2009 from Seattle WA - Adult Album Alternative, now Air 1)
KSMT Breckenridge, CO (7/18/2012 from Seattle WA - Adult Album Alternative)
