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.

KPFA, KPFB in Berkeley, KFCF in Fresno- the later reached my adolescent home town in Tulare Co, and Tuesday night was  Maximum Rock and Roll in the early 80's
Growing up in Seattle, my first listening was to KAYO, an AM country station.  My parents liked country music and it's what I first started listening to. 

Then I discovered pop and rock and KJR AM, and then KISW for "heavier" rock and KZOK for "album oriented rock" (as well as crazy stuff like Dr. Demento).  Later, many of the KISW DJs left and went to KXRX, which was a great station while it lasted. 

In the 90s (not exactly my youth anymore), there was KNDD and all the "alternative" bands like Nirvana, Soundgarden, Pearl Jam, Janes Addiction, and so much more.  When alternative started to transition away from the "grunge" sound, I lost interest and "mellowed out" to KMTT (The Mountain) which played " Adult Album Alternative". 

I grew tired of that and for many years stopped listening to radio for the most part when most radio stations were taken over by "personalities" that were all talk and no music. 

These days I listen to KNKX while working.  NPR news in the morning and afternoon and great jazz and blues the rest of the time and a good signal.
KCAC 1010 AM Phoenix, "The Joint That Gives You The Heaviest Hits", a daylight hour only underground radio station. Frequently broadcast alerts ("Bad brown acid" at the concert, "Don’t come bustable, or you’re likely to be burned") and was non-commercial, free-form radio. Later morphed to KDKB FM, "Flagship station of the Dwight Karma Broadcasting Network" (the one and only Dwight Karma station!). Had some really good times there on-air (and off) with DJs "Toad Hall", "The Amoeba", William Edward Compton (aka "BS Bill") and a few other pals.
CHOM Montreal in the mid 70s.The very best DJs, music and commentary.They were ahead of the game.When up and coming bands were touring there, they usually had the frontman(woman) interviewed live before the gig...
Growing up in L.A.in the 60's and 70's- it was all about KHJ, KLOS (Smith here), KMET.  Those were the days when the DJ's were into the music, not just talk radio where they gave opinions.  I moved to my mother's home town (Albuquerque, NM) after I got discharged from the USMC in 1980.  The now defunct KQEO, and now KZRR still play on my tuner.  Ed FM is playing right now.  
WTIX New Orleans...they were the first to use the term "Top 40"
KAAY Little Rock...50kw blasting at 1090 AM and pretty much covering the South at night
KHJ Boss Radio Los Angeles...the greatest Top 40 station ever with some of the best Jocks in the Country
WRAS, the 100k watt student-run radio station of GSU in Atlanta. Now it's just another useless NPR outlet here, duplicating the one at 90.1, WABE, formerly the classical station. Used to love listening to "My Word" on WABE on Saturdays as I was baking the breads for dinner service at Carbo's Cafe in 1980, a British game show of considerable philological depth and great wit.
Los Angeles area radio stations I listened to:

KHJ - Top 40 AM early 70s
KMET (aka “The Mighty MET”) - FM Album oriented rock mid 70s to early 80s
KROQ - FM Alternative rock late 70s to mid 80s
CKLW-Kid
WDRQ

WRIF-Teen
WABX
WLLZ
W4

WJZZ-College/Young Adult
WDET
WQRS

Currently listen to mostly sports/talk radio WXYT
Thanks to all for your replies.  Good to hear the history of your thoughts and the stations and on air people that helped to create those thoughts (and likely, feelings).  All but one of your posts were on point and great to hear/read. 
Only one poor response from a person's first post.

Up until the time I was 14 (which was in 1970), it was KILT AM (610) in Houston. They played all the pop/rock. 

After I discovered FM, it was KLOL (101.1) in Houston. There was a disc jockey in the evenings named Crash, with a deep laid-back voice, who introduced me to lots of bands I'd have never discovered otherwise.

In the mid-to-late 70's I was in the Air Force, stationed in Austin, and my radio was tuned to KLBJ (93.7) which played a great mix of all genres.
Seattle in the 1960's Top40 era had two great radio stations.
KJR-950 and KOL-1300 had wonderful personalities that featured great rock&roll music.

You will never experience that magic time again. 
WUSF FM, Tampa FL.  
Spent my teen years in St. Pete, where one of my favorite things was listening to “the Underground Railroad” Saturday night at midnight.

In stereo. The show opened with the sound of a steam train chuff-chuffing from left to right in my headphones and the DJ would announce 📣 you’re listening to the Underground Railroad and, being FM, would play entire albums, ten minute songs, long jams like nothing you’d hear outside of a record store.

I first heard John Mayall, Brian Auger’s Oblivion Express, Savoy Brown’s Hellbound Train, The True Story of the SS Titanic by Jamie someone or another, 

” it was midnight on the sea the band was playing nearer my God to thee, fare thee well Titanic fare thee well, they wouldn’t take Jack Johnson on board they said this ship don’t haul no coal, fare thee well Titanic, fare the well.”

Broad-based musical tastes were reinforced by my brother’s collection of things like Tangerine Dream, Moody Blues, Rolling Stones, Genesis, ELP, and more, also heard on WUSF.

The college used to hold Sat night festivals on the riverfront at its Tampa campus which were fun.

good times.  Thanks for asking the question.
Tidewater Virginia area early to late 70s -
WGH FM classical
WOWI FM Progressive rock
WNOR FM More crunch, less nuance to their rock
WMYK FM A mixture of WOWI & WNOR that
replaced the former when it changed formats.
Cleveland Ohio early 80s
WMMS-FM The only game in town
Are you kidding? James Gabbert, K101, 100,000 watts in 1970 stereo extravaganza. His radio broadcasts on Friday nights were entirely for audiophiles like us, the best engineered recordings, trains coming through your listening stage, incredible, so so memorable!!

Mostly college and/or public radio stations for me:

WRAS - Atlanta (Georgia State) 
KUT - Austin (Univ of TX)
WDET - Detroit (Wayne State)
KBAC - Santa Fe ("Radio Free Santa Fe")
WFCF - St Augustine (Flagler College)

I've seen CKLW in Detroit & Windsor, Canada mentioned frequently. Many years ago at SXSW, they showed a documentary about that station called: "Radio Revolution - The Rise and Fall of the Big 8." It was excellent and I highly recommend it (you don't have to be from Detroit to enjoy this one). Hopefully it is still in print. 

WKBW Buffalo, NY. Tommy Shannon was the top DJ. They always had the top hits of the day 50's and 60's as soon as they were released.
CKLW "The Big 8" out of Windsor,Ontario with a transistor radio,
upon acquiring my first fm tuner, WABX, WRIF (may have been WXYZ at the time) and later WWWW (W4) all out of Detroit. It was a great time for fm radio. WRIF and CKLW are still operating to this day.CKLW is now am800, talk and news.
WMMR 1969-1972. T. Morgan, David Dye, Luke O'Reilly, Steve Martarano, Michael Tearson
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.
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. 
KUNM in Albuquerque—my cousin Paul was the station manager in the mid to late 70s, and he had really eclectic tastes. 
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;

I lived in Iowa City and was able to pick up WLS.  I had a table radio for when I was awake and a small transister radio that I listened to in bed.  Really looked forward to the top 3 phone requests and actually called in when my parents would let me. 
I may mispell their names but there was Art Roberts, Larry Lujack, Dick Biondi, and others I am forgeting.  I also listened to KIOA in Des Moines and KAAY in Little Rock, but loved WLS the best. 

In living in Iowa City and Madison, Wi. I traveled to many places for business including Chicago, NYC, Copenhagen and many others but Chicago had my heart.  It didn't hurt that a friend had a furnished, unused condo in Lake Point Tower near the top that he let me use.  Because of it being the prime of my earning career, I/we ate at the best of Chicago at the time and attended music and theater shows.  I believe that my young attachment to WLS was the beginning of my love of Chicago.  I was also attached to the famous/best Greek restaurants.....oh, the good old days. 

I suppose that my Mother's love for the Cubs had influence on me.  I have no idea how the Cubs became her tems, but she did not watch any other MLB games, just the Cubs.  Like most Cub fans, she loved them win or lose. 


 
Art Roberts on WLS and his 3 Most Requested Songs in Chicago was every night listening for me. Heard my first Beatles music there. Sleeping out on the porch all summer with my AM radio trying to get Art or Tommy Shannon from Buffalo, WOWO in Ft Wayne, or Wonderful WYNO. It wasn't long after that I scrapped together enough paper route money to buy a Sony R/R and recorded all of my favorites from a mic taped to that same radio.
Before FM radio up here in Alberta, it was 630ched AM radio, then K97 FM, then 103 The Bear FM.  I lived in Eastern Canada for a few years it was Q107 FM out of Toronto. When I was able to screw the svr6 cable tv line into my AKAI stereo tuner in the 80's I use to get US stations from Washington and Montana etc, which was a bonus, my first taste of "commercial free" music. 
In Des Moines, IA Beaker Street (Little Rock?) in the 60’s/70’s and KFMG starting around 1970 until I moved to Los Angeles in 1977.

In LA it was usually KROQ (Rodney on the ROQ) and later on added a Reggae show hosted by Roger Stevens (sp?).

I recall picking up Beaker Street (car radio) as far North as Minnepolis starting around midnight when attending concerts in the area.

CFNY 102.1 - The Spirit of RADIO
First started as a pirate radio station broadcasting from a boat on lake Ontario. Then moved to a little house/shack in Brampton Ontario... and onwards from there. Was the best damn alternative to EVERYTHING station.
I grew up in the suburbs of NY. The station,  if I remember correctly was WNEW FM. Allison Steel was referred to as the Night Bird. She came on around 11PM nightly. She had a sultry voice that just drew you in!  Her program was so orchestrated  that she would almost literary take you away.  All of her songs blended into a theme. One  song seemed to take you right into the next so smoothly. Not like so many  other DJ's that would put you into a frame of mind and then on the next song  rip you totally out of where you were. This all w/o the fanfare of the funny cigarettes.  Going back almost fifty years. Robert TN
Mid-late 60’s…WPOP & WDRC both AM stations in Hartford CT. As a youngster at the time, the many DJ personalities also added color & drama to the listening experience. One example here. http://www.wdrcobg.com/griffin.html
What seemed absolutely scandalous to the teenaged me is just so ho-hum.

Then to FM!!!!!!!! WPLR in New Haven. Coincidentally, have a 50 year old city bus cardboard advertising placard (fluorescent orange w/black script) that hangs on my garage wall:
“WPLR 99 rock - up your FM dial…”

Sweet memories!
WRPI; Troy NY 1970s
WNEW; NYC 1980s - 1990s
WFUV;  Bronx NY  1980s - 2020
WBGO; Newark NJ 1980s - 2020

Scott Muni, Dave Herman and Dennis Elsas were some of my favorite DJs

Pete Fornatale's "Mixed Bag" and Vin Scelsa's "Idiot's Delight" Saturday evening shows on WFUV were always popular in my circles of friends.

In NYC, it was WNCN, an all-classical station that competed with WQXR.
In those days, you could listen to the Met Opera on Saturday afternoon via WQXR, hear a full opera recording that evening on WNCN, and hear a recorded opera on Sunday evening on WQXR. Both stations had a policy of playing only complete works. After WNCN died, WQXR started avoiding vocal music except for the Met broadcasts and began to play individual movements from symphonies. End of a Golden Age of NYC radio.
Away at school in the 4th grade in the mountains of Virginia from 1957-1961, we had limited radio reception.  I had a cream-colored Zenith radio that was about 8" high and 12" wide and about 3-4 inches wide. I looked at a bunch of pics of old Zenith radios and did not see one that looked like it.  

Anyway, since my grades were good, I was able to do study hall in the dorms, and used to listen at very low volume to WOWO, Ft. Wayne, Indiana, which was the only station back then that came in clearly for any length of time.

Later, back home near Williamsburg, we had WGH radio, which was for teens at night with a great disc jockey named Roger Clark.  This was in the early 1960's--the birth of great music. Then I went to college and we had WCHL.

I know it is a terrible thing today, but back then WCHL used to sign-off with an a capella version of Dixie performed by the glee club that was the best version of the song I have ever heard.  It was truly mesmerizing.

I contacted them a few years ago--WCHL is still there--but of course they had no idea what I was talking about and of course all copies of that version were long gone.  Sad, but times change, I guess...
Back in the mid to late 70's there was a radio station in Columbus Ohio called Stereo Rock 92. Their competitor was QFM 96 that still thrives today. Rock 92 had something called "Midnight And Other Beast". Every Friday night at midnight they would critique a complete album. Remember,, back in those days there was an explosion of new rock artist and mainstays releasing album after album rapid fire.. So at midnight they would explain the album in detail, introduce all the members and what high lights we should listen for during the first half of the album. After side one was played the disc jockey would do the same thing for side 2. No commercials, just music... really cool. 
Boston stations - 
WMEX - AM in the 60's - top 40 hits
WBCN - FM after that for rock  - Peter Wolf (early DJ)
Charles Laquidara - legendary
WFMU 101.1 Freeform radio from Upsala College, NJ
WNEW 102.7 Scott Muni and company in NYC, Progressive Rock
WBAI     99.5 Pacifica Radio in NYC
WRVR  106.7 Jazz radio in NYC until 1980
WNCN  104.3 Classical Music format until 1980 
WCVF     600 carrier current AM radio at SUC Fredonia, NY

Radio in NYC was really lively and interesting in my youth, from around 1969 until about 1979 or so…and then it just died. It became lifeless and soulless as the “professional” radio programmers took over. There are a few good stations today, WNYC, WQXR, and WBGO, but the rest are unlistenable.
WTSR, Trenton State Radio. They had a great Reggae night where I discovered tons of bands I, to this day, never would know.
In Boston, MA: WBZ AM, WBCN for rock, WJIB for easy listening to go to sleep to, WCRB Classical Radio Boston, WRKO for pop.  This all dates back to the 60s and 70s because I am old as f***.
