I also live on an island and we too have several outages a year (which
can last from seconds to days). Most are caused by branches blown down
by wind, hitting and breaking the power lines (it is slowly getting
better as Puget Sound Energy has proactively been trimming trees before
they break). I have four UPS devices in various parts of my house. The
shack and my home computers and DVRs are connected to 1000VA TrippLite
UPSs I bought at Costco several years ago and these also protect against
surges. I don't try to operate an amp when the power goes out, but have
run 100 watt radios barefoot for several minutes. The batteries in my
systems probably need replacing and when I do that I will try to silence
the darn beep that they make (I can tell when there is an outage without
hearing that noise). I will also look into setting up a 12V system like
you described.

In response to Stengrevics : To deal with a power line noise problem, someone
suggested I try an
uninterruptible power supply (UPS).? Does anyone have any experience doing
this?? If so, what UPS specifications are appropriate to handle the K3S?
For my Elecraft K3S/P3 I am using an Astron RS35M power supply which feeds a
West Mountain DC-to-Go with attached Radio Power Gate PG40S and RigRunner
4007U. My battery is a 79 amp hour AGM. I live on an island and at stormy
times of the year, we experience power losses and multiple short hits. This
combination has been quite satisfactory.
