KOSF is an FM radio station broadcasting at 103.7 MHz. The station is licensed to San Francisco, CA and is part of that radio market. The station broadcasts Classic Hits music programming and goes by the name "iHeart80s @ 103.7" on the air with the slogan "80s Music for San Francisco Bay Area". KOSF is owned by iHeartMedia.

On April 8, 2011 the station flipped from classic rock as "103.7 The Band" to oldies as "Oldies 103.7." The move was likely affected by the recent change of 102.1 from classical to classic rock.

Listener Comments and Reviews

Add more Soul,Motown,Disco and Pop with the Rock hits. You guys sound too much like KUZX 102.1 (The Fox) If you going play the greatest hits you play what was in the Top 40 in the 60's & 70 with some the 80's not just rock. KRTH L.A. and WCBS in N.Y.C are good examples. If people want to hear Classic Rock they have KUZX and KSAN. There should be one that plays Classic Top 40.

What happened to The Band??? We loved this station... Then when listening this past week..Wow back to the same old crap that all the other radio stations deliver...We loved Pink Floyd, Zepplin, Bad Company The Bee Geez...Really??? Yea you sound like KOIT....Just another radion station down the tubes.....

I agree I loved The Band, and now, "NO", know it is not classic rock. I am done, not listening any more!!!! unless you bring back the original format!!!!!
By: Kim Sims on April 9, 2011

I really liked the Band's format. This moldy oldie approach is tired and way too common. I guess it's back to KFOG for me.
By: Tom Johnson on April 16, 2011

The band always had something worth listening to unlike many other stations that play one good song every three overplayed regulars. rip will be missed
By: The Band always made me happy on April 19, 2011

This new format radio station is the best!!!!!!!!! I love you play a wide list of artist. I really love the mixture of rock and roll, soul from Wilson Picket, Bee Gees, Rolling Stones, The Contours?, it just good music all across the board. There is no other station like this. No one wants to play the 60's music anymore. And this is great music. Keep it up!!!
By: Cassandra on May 15, 2011

I think the current format is awesome. I have not heard a song I don't like. Keep It as is. YOU ARE ROCKING TO THE GOODIES.

Come on ... SF is so in need of good radio stations. The Band was often pretty good ... at least playing some tunes that pushed the edges a little. Now you've gone safe and syrupy. Why not push it even a little more ... play some more alternative rock of the 60's, 70's, & 80's ... ? I bet you'd have an audience.
By: Nicole Barens on May 24, 2011

Love, love, love this station and line-up...there are no other stations like you in the bay area This station finally got my husband to stop listening to talk radio and hes' much calmer now...the oldies always make a person feel good...thanks!!!

From reading the comments sounds like you ruffled some feathers on a change over. Anyway, I just started listening to you guys and have found the format a little more varied than the other stations around the area. What I have seen with these changeovers is for the first few months the music selection is generally very wide and contains songs that haven't been played for a long time on the radio. However after this initial period what seems to be the rule is they settle down into the same 100 songs that every other station has been playing for years and make them incredibly boring. My suggestion (and hope) is to truly look for variety in the artists that you feature. Steve Miller did more than the three songs the other stations have played to death, so have all the other artists and these are songs that we who grew up during this period, listened to. For example Simon and Garfunkle "My Little Town", Old Friends" great songs that were popular back then but unheard of today on pop radio. How about the "girl groups" of the early sixties, The Ronnets (OK so I can't spell)The Shirells, the Chiffons? What about some "Blue Eyed Soul" the Righteous Brothers did more than You've lost that loving feeling, which has been played to death. This list could go on including music from the late sixties, and may other genere. I could go on however my point here is if you really want to be a viable station that people actually talk about you need to open up your library and play the songs that were popular during the "60's, 70"s and 80's" that the other guys are missing. I'm listening and hoping you don't turn into the corporate "LA said this is our list and thats what we'll play" station, if you do you will lose people in droves. In the meantime I am enjoying your programing and hope my words don't fall on deaf ears. Ya need a program director? Thanks, Mark

I love this station, I work early in the morning so I'm on the road before 5a.m., and love cruising to your music, takes me way back and think about the great times I had when I hear a song... Keep on Rockin!
By: Tina Colon on September 1, 2011

I finally found I station I enjoy (other than 96.5) so please please don't take it off. I'm a baby boomer and especially enjoy the songs of the 60s. Thank you!

Listeners of oldies 103.7 write the station and ask them to add more rhythmic (urban Leaning)oldies to their music mix having one station that will play fleetwood mac, earth wind and fire, eagles, commodores etc. on one station.

You have no idea how long I've longed for a station that plays the music I grew up with....Gawd it sounds soooooo good. I don't know how to thank them, but God bless 'em!!!!!!!
By: Kenice Cozens on January 6, 2012

I have enjoyed this station and the music, especially driving to and from work. However, I am very unhappy with the new "Don Blue in the Morning". Too much chatter and advertisements. I also think the "blooper" calls are mean spirited and not amusing. Some of the recipients sound devastated. This is much the same format he had on previous stations years ago. I will look for another station from 6:00am-10:00am and then listen to 103.7 the rest of the time- too bad

Use KOOL 94.5 in Phoenix as model for you music programming. Their a top rated station and music variety is excellent. They are the best Oldies/Classic Hits stations. KRTH(K-Earth 101 in L.A is pretty good and WCBS(CBS 101.1 FM) in has a wide rang of music too.

Hello. 50 years ago this summer Warner Bros. released our record, "Mill Valley" by Miss Abrams and the Strawberry Point School Third Grade Class. It became an international hit and we appeared in Rolling Stone (we were 18 year-old Annie Liebowitz's first assignment) Life Magazine, Newsweek, on the Smothers Brothers show, and on many of the local radio stations. Francis Ford Coppola shot the music video which is on YouTube. So it would be great to have you play the record, and perhaps do a nostalgia piece on the record's 50th anniversary! Here's what Ben Fong-Torres wrote about it: "The way Miss Abrams and her Strawberry Point School 3rd Grade Class sang about it, Mill Valley was paradise on earth – especially when so much of the earth, in 1970, was in chaos, with a war overseas and battles within our own borders. But listening to this school teacher and her children rhapsodize about their home town, “where life feels very fine and free,” allowed listeners to escape, if only for a moment—or three. That’s what the best pop music has always been about, and that’s what makes “Mill Valley,” both the tune and the town, timeless." -Ben Fong-Torres Thanks so much, Rita Abrams
