RKOR

RKOR was (is?) a Contemporary music station located in Granollers, Spain. They have no official website and I'm pretty sure they are no longer in operation. I did find a YouTube clip with a few RKOR jingles though. The guitar on the sticker is in the shape of Catalonia which is an autonomous region within Spain where Granollers (as well as Barcelona) is located. The red and yellow stripes resemble the Catalonian flag.
