CKIX

Licensed to St. John's, Newfoundland and Labrador, 99.1 FM CKIX carried a Country format from its launch in 1983 until 2002 when it flipped to CHR as "Hits FM". 
"No Flyers Please" seems to be an exclusively Canadian movement to reduce the amount of unsolicited junk mail.  This sticker was meant to be put on your mailbox to let the carrier know to throw away such advertising.  As an employee of the US Postal Service, I'm not sure this would work in the States.  It's my understanding that the carrier is required to deliver everything in their possession and it's up to the addressee to get off the mailing lists of these advertisers.

A "Hits FM" van turns into "Shit FM" circa 2002.
