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.

Bartok Radio, Hungary. The most educational classical music station I ever ran across with fantastic sound quality and content. I grew up on it. Thumbs up for the Huns! ;
Now it's available as internet radio as well... sound quality not the same, but you can get the content and maybe pick up some Hungarian along the way;
KUNM in Albuquerque—my cousin Paul was the station manager in the mid to late 70s, and he had really eclectic tastes. 
WBCN Boson.  Peter Wolf had the night shift.  Great station.  If I recall correctly, they were the first to play U2 here in the states. 
Then in the UK listening first to Radio Luxembourg and then the pirate radio stations - Radio London and Radio Caroline - all on my 'tranny' (transistor radio) on Medium Wave of course. 

Also BBC Radio 1 and the late great John Peel from 1967 until his untimely death in 2004.

It wasn't only the stations but also the disc jockeys that influenced musical taste so much - and for me the more bizarre normally the better! 

These days in CO a mix of local stations mainly in the car.
