Original Report 3/28: CBS Modern AC “Sophie 103.7” KSCF San Diego is on the verge of a format change to “Energy 103.7”

The company has applied for a call letter change to KEGY for the station. Additionally, a protected website at Energy1037.cbslocal.com and a blank Twitter account @Energy1037SD are in place.

Energy1037.com was registered anonymously on December 1 along with Z1037.com, 1037KHits.com, and NewsRadio1037.com.

In the February PPM’s 103.7 registered a 2.2 share well behind Clear Channel Hot AC “Star 94.1” KMYI’s 5.4. A flip to something CHR oriented as the Energy name would appear to indicate would place it in more direct competition with Clear Channel’s market leading “Channel 93.3” KHTS and Local Media of San Diego’s Rhythmic CHR “Z90.3” XHITZ.
