IDEC operates two closed UHF Amateur Repeaters. Repeater "Tango" is the primary at 449.580- Repeater "Sierra" is the secondary at 446.720- People interested in joining are welcome to listen to the net.
During a disaster or critical incident in which IDEC personnel are mobilized, it is both permissible and encouraged that licensed amateur radio operators (irrespective of IDEC membership) utilize City of Irvine ham radio repeaters to communicate urgent matters, or pertinent and brief questions that may arise, when other forms of communications (e.g. cellular/landline phones) are compromised or may not be readily available. In these instances, it is preferred the Tango frequency be utilized.
