Maintenance Bottelary 20200929
Paul ZS1V and Jan ZS1VDV did some maintenance on site. This was the 3rd attempt to go to site. The previous attempts failed due to a GSM failure on site preventing de-arming of the alarm. Last night a remote was used to de-arm the alarm. For a few while the alarm did scream inside the hut (an unpleasant experience that is not recommended).
Left for site: 16:30
The WiFi based site internet link device firmware was updated and the link reconfigured. The Multimode Digital UHF repeater and VHF DSTAR repeaters are back consequently back online.
Some power maintenance was done and monitoring equipment installed.
The Allstar link node was installed. It is currently running on 433.500 MHz simplex. This node is linked to the WCRWG hub node, which has a permanently linked node to the Gifberg 145.7375 repeater. Once testing is complete, the link node radio will be switched to link to the Hawequa 438.800 UHF repeater, bringing Gifberg onto the main link network.
Some general network maintenance was completed.
The weather on site was foul and the wind made the walk out with equipment in the dark treacherous.
Home and unpacked 20:30.
