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. 

@jerryg123 - I wonder if Terri Hemmert is still working there?
@valinar - I spent the summer of '75 in St. Lou and listened to KSHE quite a bit. I wanted to invite Sweetmeat to a BBQ but never got around to it...
Houston stations, KILT AM (My introduction to the beginnings of the British Invasion thru Post-Woodstock/Pre-Donny and Marie), KLOL 101 FM “The Air Corps” (Aforementioned Post-Woodstock thru rehab “aka the aftermath of the late ‘70s into some indeterminate point-in-time involving the 1980s”), and KPFT Pacifica 90.1 (My intro to music genres beyond Top 40 Pop/AOR with emphasis on the Austin Scene)
