About Us

Welcome to the Southern California Repeater and Remote Base Association (SCRRBA) website!  We are a volunteer organization providing coordination of a number of heavily utilized amateur radio frequency bands in Southern California.  SCRRBA is a member of the National Frequency Coordinators' Council (NFCC).

Our Goal

To provide frequency coordination and achieve solutions to problems on the 29, 51, 420, 902, 1240MHz, and microwave frequency amateur bands in the Southern California area.  SCRRBA has provided frequency coordination of these activities since 1970.  We actively participate in the numerous Federal Communications Commission rule making proceedings pertinent to our activities.

SCRRBA maintains over 2,400 frequency coordination records.  These data represent the activities of approximately 600 relay type amateur radio systems constructed by our members.  Most of these systems operate on the UHF (420MHz) and higher amateur frequency bands.
