Repeaters

A variety of 2m, 70cm, and 6m repeaters are available. These repeaters cover areas from north of Proserpine down to south of Rockhampton, and out west to Clermont, Emerald, and the Central Highlands.

Many of the 2m and 70cm repeaters throughout the region are linked, and have both IRLP and Echolink available. We have also been experimenting with digital modes and are progressively updating the repeaters to suit.
