John,
I haven't read all the replies yet. I'm sure you will get a variety of
responses, such as mine.
About 40 years ago when color TV's were more expensive, my neighborhood
got a momentary hit in the power, and it came back with a voltage spike
that took out too many TV's to count. To prevent that from happening to
my ham gear, I made a box with multiple outlets all switched by one
relay that locks up through it's own contacts. I have momentary push
button switches to operate, or release, the relay. Should the power
take a momentary hit, the relay drops and opens the AC line to my
equipment. If the power comes back with a voltage spike, my equipment
doesn't see it. (This may result in a discussion about MOV's) I have a
100 watt station.
I prefer to float a battery across my 12 volt line to allow me to
properly shut down my equipment should the power go out. I have had
several qso's with people who use 12 V battery power exclusively. Some
live where there is no power grid.
Also, I have a UPS that powers a lamp at my operating position so that I
can see to power down my equipment. I hope to eliminate this with a
good 12 Volt LED lamp when I find one.

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?
My apologies if this has been previously discussed. Please do provide a
link if it has.
