The Knobby Repeater site near Brisbane Queensland.
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.

Hi everyone, D-Star is going well with interest winding up for many reasons. I’d just like to say a big thanks to Waratah for his work on this site. Waratah is back, new VK4 callsign and all ….. Welcome back your great contributions have been sorely missed.

Recently and over the last couple of years I have caught up with Steve Wood VK4SM and its great to see the D-Star work that has been acheived in Central Queensland. I was up again only a few months ago and there are some great multi mode systems , particularily Mt Archer in Rockhampton, works really well on D-Star and DMR and the site on the mountain, simply stunning.

Does anyone have any news, articles or photos for the site, whats your favorite D-star setup , best contact ( must be photo on screen) for the site,
