For me is important check the room temperatue and also the PA heatsink, but temperature sensor are necessary. Also necessary is an A/D converter and the inject this signal in an USB adapter for read data on Linux. > SWR/Antenna - Bird and others make inline wattmeters that have voltage > outputs, but if you're using commercial grade antenna components on your > repeater, it has been shown that antenna systems rarely fail. > This point of failure is important especially in thunderstorm season, just for understand if the rpt don't appear to answer for a line problem or because the antenna is broken...but finally, at this point is not important known if the antenna is broken... > UPS: There are daemons that can be run on Linux that will monitor > certain brands of UPS if the UPS has such a feature built in.
