Thanks Mike - very helpful responses.
I just spent a part of a pleasant pre Thanksgiving morning looking at transmitter locations, and suddenly things became clear. All the stations we have trouble with are transmitted from towers in the Cascade foothills (Tiger Mountain). We are halfway down on the west side of Phinney Ridge, a 400’ high north/south lateral moraine.
KEXP, a terrific music station, transmits line of sight to us from a tower on Queen Anne Hill. I’m gonna redouble my uncompressed transmission campaign! (Highly recommended streaming, I know a lot of folks listen to it internationally).
KNKX, jazz and news, has their primary transmitter on Tiger Mountain. They have a small secondary transmitter south, across the Puget Sound, which we pick up, but it is only 18,000 watts and a ways a way.
KUOW, public radio news, have a huge 100,000 transmitter on Capitol Hill - not line of sight, but I think it just blasts out so strongly it is always a good signal.
KZOK, classic rock, Tiger Mountain, bad.
KING, classical, Tiger Mountain, bad.
I think I probably just stay the course with the ST-2. I might just bite the bullet and recognize streaming is smart here for the tough stations.
Still can’t believe how listenable this NAT3 is! My wife and I just enjoyed listening to it last night by the fire.
