The Isaacs DMR Repeater is OPERATIONAL.
CRARC has a DMR repeater on Isaacs ridge. DMR, or Digital Mobile Radio, is a commercial international open standard digital radio platform. Following multiple PA failures, the old Motorola DR3000 has been removed from service and replaced by a Tait TB8100 with an MMDVM providing the digital side of things. CRARC’s repeater is linked to the Australian DMR+ network.
Before transmitting, you need to register for a global DMR ID. This is a unique, global identifier which identifies your transmitter. You only need one ID unless you plan to transmit from multiple radios at the same time. The same ID can also be used on any of the DMR networks. Registration for an ID is free and easy. Information can be found at the RadioID website.
