Over the past year or so I have been in the process of replacing all of the battery backup systems at sites with brand new UPS units.  The previous battery backup consisted of a large tractor battery and an interter typically used for photovoltaic systems.  These systems worked well but the batteries were fairly bulky and starting to age.  In addition, the inverters were starting to fail one by one.  The new UPS units likely will not have nearly as much runtime but it will be more than enough for the remote control to call and alert me of a power outage.  Eventually I would like to have long term backup power for each site (including the transmitters).

Apparently our neighbor at the site had suffered a lightning strike and was off the air at the time.  Our gear was unaffected.

Reid and I had intended to completely re-wire this site today but did not have time on this visit due to the unexpected emergency repairs in Gillette.  At least getting the new UPS installed is a start…

Battery from old backup system–Note the bulges on the side!

New UPS installed in the rack

Meter readings at zero…These guys are definitely off the air.
Glad it isn’t my transmitter!
