Australia’s Highest DSTAR Repeater is now operational
439.300MHz -5MHz VK4RBM B
The Blue Mountain repeater site is without any doubt Central
Queensland’s best amateur radio repeater location. Surrounded by
thick tropical rainforest slopes and standing at 1040m, this truly is
a remarkable site.
challenges, the main one being access. The answer
is the help of a Jet Ranger helicopter and some superb piloting skills.
the site. As we approached the site, the tower could be seen poking out above
the thick rainforest. The landing site is a small rocky area with
surrounded by trees, then we touched down, unloaded the gear, and the
APRS, 3G modem and solar regulator. The work was completed in
record time, and the chopper came and picked us up before the clouds
rolled back in.

The Blue Mountain DSTAR repeater is running on test, ready to be taken up to site. We are using APRS telemetry data to monitor and control the DSTAR repeater using the WX3in1 APRS modem. The analog inputs are being used to measure:
- Battery voltage
- Transmitter cooling fan current
- Raspberry Pi and DVRPTRv1 current
- DSTAR transmitter temperature.
As you may be aware our VK4RBY Black Mountain site was broken into a few months back and some gear was stolen. We are now backup and running on DCS028Q with a 70cm DSTAR repeater. Work is underway to install a 2m multimode repeater at this site in the coming months. Historic data usage shows we use about 1.5GB per month. We are testing a prepaid Optus simcard to provide internet access. The Optus deal is good value, $130 for 22GB with a 2 year expiry.
Alright, get your head out of the sand. Stop questioning why we should do one digital mode over the other. Multimode repeaters are here. It is with great excitement that we can announce the Mackay area multimode repeater is now operational. This really is a great achievement by all the volunteers who helped this get off the ground. We encourage all other clubs to follow a similar direction and put up a multimode repeater that can fulfil the needs of just about every digital voice mode there is. There really is no excuse to not put up a digital repeater. We have been mainly testing our repeater on DSTAR and P25, and by all reports it is working great. Our setup is using a Tait TB8100, and Odroid XU4, and MMDVM modem. We also have the added bonus of a DVRPTR v1 modem also connected to the Odroid CPU. The DVRPTR v1 runs a standalone 70cm repeater and our 2m frequency runs as a multimode repeater. The modes supported on our 2m repeater are DSTAR, P25, DMR, and YAESU C4FM.

This repeater is not linked to the closed DMR MARC system. The DMR side is using brandmeister network. This network supports most DMR radio’s and allows remote DMR hotspots such as dv4mini’s to connect to the 4805 reflector.
