What were the radio stations of your youth that helped you on your music/audio journey?


I am older so my radio stations of influence were in their prime during the British invasion and many, many American singers and groups.  
The stations I listen to the most were WLS out of Chicago, KIOA out of Des Moines, KAAY out of Little Rock, Arkansas and KOMA  out of Oklahama.  When I was in the Air Froce I had a few stations near the main base I was stationed at outside of Rapid City, S.D.  
Of course systems and better and better systems and FM became the dominate source for broadcast/online music.  I did learn much of what I liked and eventually purchased through early radio listening.
I still listen to radio mainly for Jazz stations and NPR news.

CFNY FM in Toronto... 

Mind you this before they were bought and then radically changed their programming to sound like every other radio station.

Great in the 70-80's timeline.
KISW-FM 99.9, seattle- progressive rock station that veered amazingly far into frothy pop. this was back in the glory days of album-oriented rock and they would play the whole album. it was where i first heard the rick wakeman album, "rhapsodies" [very late-70s cheesy synths].
KING-FM 98.1, seattle- back in the 70s a "progressive" classical and jazz station, at night they’d play jazz. it is where i was first exposed to Canadian bandleader rob mcconnell.
KLAY-FM 106.1, tacoma- a progressive/new-wave station where i first heard those kinds of tunes, where i first heard punk, late 70s.
KNBR-680AM- san francisco, late 70s then a progressive news station, where i first heard left-wing politics. i heard this station via atmospheric "skip" for the first time.
KSL-AM 1160, back in the 70s the originator of a late night call-in talk show called "Nightcaps" hosted by herb jepko. very laid-back informal format, adult in a very calm way. reasoned discourse. i miss it.
