The MMDVM VHF repeater has been installed at the Knobby site today. The equipment is the same Tait TB8100 base station together with a new MMDVM modem. DSTAR is shared with other modes on this repeater. The default reflector is currently set to REF023_C.
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.
Regional Queensland leading the way for Digital Voice
Central Queensland now has the best digital voice coverage in Australia while the big cities seem to be lagging behind. From helicopter lifts to access on quad bikes nothing is stopping us from moving into the future of digital voice. The DSTAR experience on our multimode repeaters is fantastic since upgrading from the Arduino Due MMDVM to the STM32 Nucleo MMDVM. The Pi STAR image has also been the most popular choice for setting up your own hotspot. The momentum has not stopped up here in the north with more and more amateur radio operators coming on-board and giving the digital modes a go! We are encouraging other clubs to follow our lead and start converting under utilised analog repeaters to digital voice repeaters. It truly is a lot of fun to build your own digital repeater from scratch. Check out the multiprotocol reflector at www.xlx028.org
Mark Kyle VK4KZK has been busy building a new 2m repeater for the Maleny site. VK4RDS 146.7375MHz -600KHz has now been kitted out with a MMDVM modem and a Pi-Star image. DSTAR P25, C4FM and DMR are supported on this new setup. The DSTAR only repeater remains unchanged on 438.550 MHz -5.2MHz. Mark has built in a few smarts to this setup such as remote power cycle and 3G modem connection for internet access. Sunshine coast radio amateurs can make use of well priced second hand VHF radios such as the Tait 9100 p25 radios easily found on ebay. Dont forget to try the new multimode reflector DCS389D. This special reflector allows operators in all the different digital voice modes to talk to each other. For example I can talk DSTAR to the other party that is on DMR. We are really starting to see some amazing progress in the DV space. These multimode reflectors are a step change in what you can achieve using digital voice modes. They allow all the different flavours of digital modes to talk to each other!
