KXOA

The KXOA call letters in Sacramento, California have a history going back to 1945.  They started out at 1490 AM and has appeared at different dial positions with various formats on both the AM and FM dial through 2004.

KXOA "The Arrow" (All Rock and Roll Oldies) was a Classic Hits station from 1994 to 1998.

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"
The frequency is currently Adult Hits KQJK "Jack FM" licensed to Roseville, CA
