Elsewhere around Puget Sound, I like KBAI 930 for Progressive Talk. CBC Radio One 690/88.1/90.5, CBC Radio 2 105.7/92.1, KWLE 1340, KGRG 1330, KUGS 89.3 and occasionally, KSVR 91.7 around Skagit County. CFOX is OK.
I'm not into KISM because they're so predictable. The same bands playing the same narrow selection of their biggest hit songs (even KZOK and CFMI shake it up a bit with a few lost cuts and one hit wonders. Which KISM NEVER does.) As far as the JACK stations go, CKLG 96.9 is still the best (although I miss Larry & Willy.) CBUX still whips the pants off KPLU when it comes to their jazz programming (I think KPLU should monitor CBUX for things to add to their playlist they're overlooking - they're a GOLDMINE.)
KAFE doesn't really register because I'm not particularly an AC fan (even around the holidays I prefer KRWM for Christmas tunes over KAFE because KRWM has a better selection and a few surprises.)
