Oh, the eastern part of Washington state is the bomb for MW DXing. I filled multiple log pages in the past with things from Canada all the way down to Mexico.
Agreed. In the mid-to-late 1980's I was getting some Chicago stations (not common here, even in good years), and possibly a station from NYC, from Cheney, WA, when I took my GE SR1 there on a weekender. Anything east of the Mississippi was a rarity back then unless you had really, really good equipment. I had done a lot of MW DXing as a kid but by the time the 80s hit I was discovering loops and nulling techniques... At Cheney all I had was the SR1, though.
The time I mentioned upthread where I DXed east of the mountains was Sept. 2012, to Chelan. I didn't get fantastic catches but some good ones, mainly stronger regionals that are blocked out west of the Cascade range. 700 kHz had KXLX and the ESPN station in Salt Lake City. Here west of the Cascades, KXLX is a tough catch because of 710 splatter, and I think I've only gotten the SLC station once or twice total.
I don't get down to the ocean very often. Next time I go my PR-D4W is definitely going with me, though. Along with my kites.
PS -- SWL should be great for Asia in the mornings. Even the ham bands, if you're into that.
