Is KFRC actually using Breakthrough, or were you just suggesting it? I've listened to their stream several times, and I haven't heard any jingles on there except for a simple “KFRC San Francisco” at the top of the hour, which was not JAM.
Is that the “You” package – Wasn't KFRC one of the stations that piloted “You” the first time round. In which case it's using resings of a package which is itself a resing of its package.
The “You” package was used by around 70% of the Jack stations in the country, including Canada. I've heard that package through some of the montages I have listened to.
