Careful there - NorCal is repeater-input high, and repeater-output low, SoCal is the reverse. Dividing line is the Santa Maria River. There are valid arguments for each method... Makes it lots of fun for the guys in the middle ... they have to pick the frequencies carefully to avoid lockups and a system output capturing someone elses input. >Now... back to my face down on the table...
