Tait TB8100 VHF repeater

Located at The Knobby west of Brisbane in Queensland VK4RBX is a VHF multimode repeater that supports DSTAR. This repeater has recently been removed from site to be upgraded with the latest MMDVM hardware. Shown in the pictures is the STM32 -DVM board from repeater builder in North America. This repeater is currently running under test and will be installed back at site over the next few days. The default reflector will be DCS014_B.

Reflector linking using DTMF tones is a quick and easy way to link up to reflectors. Use DTMF shortcuts to link to different reflectors. For example DTMF *23c to link to reflector REF023C. Or try DTMF D14B for DCS014B.
