NDR

NDR (Norddeutscher Rundfunk) is a public radio and television broadcaster based in Hamburg, Germany.

NDR1 Niedersachen is a local station broadcasting to the state of Lower Saxony and based in Hanover.  They were playing Oldies from the Bay City Rollers, Cliff Richard and Roy Orbison when listening live while making this post.

NDR1 Welle Nord broadcasts from Schleswig-Holstein, the northernmost state in Germany. 

NDR1 Radio MV is a local station for Mecklenburg-Vorpommern.

NDR2 plays contemporary music for a younger audience.  I heard Mr. Probz, The Avener and John Waite while typing this post.

N3 is a television channel presented in cooperation with Radio Bremen.

NDR4 was the News arm of the network and has been renamed NDR Info.

Not sure what Radio 3 or NDR3 is (or was) but the violin indicates it may have carried a Classical music format.  ORB was Ostdeutscher Rundfunk Brandenburg (East German Broadcasting Brandenburg) while SFB was Sender Freies Berlin (Radio Free Berlin.)  SFB and ORB merged in 2003 to form Rundfunk Berlin-Brandenburg.

NJOY plays commercial-free music aimed at listeners under 30.  This branch of NDR began broadcasting in 1994.

KMET

94.7 KMET (K METromedia) was a hugely successful Progressive/Album Rock station in Los Angeles, California from 1974 to 1987.  Pioneering programmer Tom Donahue brought his free form rock concept from KMPX in San Francisco and KPCC in Pasadena and, along with PD Shadoe Stevens and a host of legendary DJs, turned KMET into one of the most influential rock stations in the country.  By the 1980s, corporate interests, radio consultants, tighter playlists and staff turnover spelled the end of "The Mighty Met" and they flipped to a New Age format as "The Wave" KTWV in 1987.

WXTU

WXTU is a Country station in Philadelphia, Pennsylvania.  According to their Wikipedia page, WXTU is the most listened to Country station in the United States based on listener cume.  They have carried the same format since flipping from Urban Contemporary in 1984.

WOVI

89.5 FM WOVI broadcasts from Novi High School in Novi, Michigan.  The 100-watt station went on the air in September, 1978.

WLRT

1250 AM WLRT (W Lexington's Real Talk) is a News/Talk station licensed to Nicholasville, Kentucky.

KXOK

St. Louis, Missouri's KXOK began broadcasting in 1938 at 1250 on the AM dial.  Two years later they moved down to 630 AM where they would remain for over five decades.  KXOK pioneered the Top-40 format in the early 1950s and at one point was one of the five most listened to stations in the country (along with another St. Louis station KMOX.)  From all accounts, KXOK was a beloved station for a certain generation of listener and has been described as St. Louis' American Graffiti.  Tribute sites can be found here, here and here. 
The above sticker probably dates to one of KXOK's post-1975 format changes which included Talk, Oldies and News.  630 AM is currently KYFI, part of BBN's network of Religious stations.

WHLC

FM 104.5 WHLC (W HighLands Cashiers) plays Easy Listening music including "songs from the '50s through today, movie tunes and popular easy rock tunes interpreted as instrumentals."  They went on the air in 1993 and are licensed to Highlands, South Carolina.

A 1988 sticker from Rock station "Lazer 103" WLZR in Milwaukee, Wisconsin which existed from 1987 until 2005.  102.9 FM is currently WHQG "The Hog" and plays a wider variety of Rock than WLZR's younger-skewing Pure Rock format.

WDAY AM & FM

 Fargo's AM 970 WDAY is North Dakota's oldest radio station, having gone on the air in 1922.  They currently carry a News/Talk format.

WDAY FM "Y94" is a Top-40 station in Fargo, ND.  They are no longer co-owned with WDAY AM.

WKNH

A t-shirt and beer koozie from 91.3 FM WKNH in (W) Keene, New Hampshire.  The station is run by students at Keene State College and went on the air in 1971.

The koozie mentions the Keene Pumpkin Festival which is held annually in mid to late October and has set (and re-set) the world record for most lit jack-o-lanterns.  This year's festival got a little out of hand as crowds set fires, flipped cars, smashed beer bottles and rioted into the night.
