ERT

Using Google Image, I think I finally figured out that this sticker is from ERT which, until the government shut it down in 2013, was Greece's state-owned public radio and television company. 

Here's a video of people milling around in front of an ERT building followed by someone being interviewed.  Perhaps these are some of the employees who were laid off en masse protesting their firing?

Mystery Sticker - Big Dog 94.5

Can anyone identify this sticker?  94.5 KRUF in Shreveport, Louisiana used to be known as "Big Dog" but I can't positively say this is their decal.

Radio Contact

Radio Contact is a Contemporary Hit station based in Brussels, Belgium.

I'm not sure the above sticker is actually from Radio Contact.  I received it with a pack of other European radio decals and someone wrote "Francois" on the back.  Radio Contact started broadcasting in 1980 which might explain the number on the sticker.  Anybody know?

More unique magnets and stickers from New York City's longtime Freeform station WFMU.  Other decals from what Rolling Stone magazine named as the "Best Radio Station in the Country" four years running (1991-1994) can be found by typing "WFMU" in the search box. 

This is the first of 36 trading cards documenting some of the (in)famous events in WFMU history.  Highlights include DJ Glen Jones' world record breaking broadcast of 100 hours and 42 seconds and the mid-1990s sale of the station from a bankrupt Upsala College to a group of WFMU DJs and volunteers.  The cards come in a nice little boxed set which is still available at Crapola Central.

The coupon on the back of this sticker dates it to 2002 when KXOA had moved to 93.7 FM.  At that time they carried a "Hot Talk" format including Howard Stern in the morning and Classic Hard Rock on weekends.  They would later change their entire branding around Stern, becoming "Howard 93.7"
