[OZAPRS] FW: VK3CV-1 site monitoring with Site Alert

[Richard Hoskin]

Hi All,
 
Last weekend I installed a prototype of Warren's (VK3BYD) Site Alert at
VK3CV-1. (We are currently testing and proving the units.)

Site Alert monitors several parameters at remote (digi) repeater sites
such as "in shack" temperature, backup battery voltage, digipeater
transmissions and mains power failure alerts. If there is a mains power
failure then Site Alert will notify the site owner via APRS Messaging
and
place an alert icon on the map. If the backup batteries voltage falls
below a preset level Site Alert will disable the Digipeaters transmitter
until the voltage increases to an operational level.

Data from the monitored Site Alert items is fed in to the APRS network
using the TLM format (see APRS spec for more details) and can be logged
using the UI-History/Telemetry utility that comes with UI-View32 ver
1.80
or later, or via FindU using the following URLS:

Note you need to remove the word wrap from the URLs above.
