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.
