Well how about 103.1?
93.3 is a bad choice for a LPFM Station
Not sure how much better that would be considering KKCY is on 103.1 on top the Sutter Buttes (albiet, not a ton of power but still).
The FM band in Sacramento is truly an interesting one. With the thermal inversion layer in the summer, close proximity to San Francisco FM's (Mt. Beacon) and then you have signals in the North Valley with very little to block all these signals; it's an uphill battle.
