Quoting from a Y107 aircheck posted on Soundcloud: “From April 1996 through December 1999, Y107 was “Southern California’s Modern Rock”. Y107 was a synchronized trimulcast of KLYY Arcadia, KSYY Fallbrook, and KVYY Ventura, with each signal at 107.1 MHz.”
This is a sample of Y107 from the KLYY signal, recorded just a little over three weeks before a change to a Spanish Hits format.
