CORA is an OPEN Repeater Association that is FREE to all Licensed Amateur Radio Operators

CORA boasts a footprint of repeaters that covers San Diego’s East County with linked repeaters in the UHF and VHF spectrum. CORA has been provided with a Talk Group on the Western States DMR system.

With the broad coverage and multiple repeaters linked together, there are numerous points where extraneous signals can make their way into the system. Some interference issues have been traced to folks using crossband repeaters, Allstar nodes and other experimental points of access. While experimentation is always encouraged with this hobby, we ask that all stations access the networked repeaters directly through the repeaters and the Echolink node that we have all worked so hard to fine tune for signals that are as clear as possible. Thank you for your understanding.

Here are the details for the CORA analog and P25 repeaters.
