Default UPS in series?

You're not going to extend your runtime near as much as you might think.
If
you had an UPS with a clean enough pseudo-sine waveform to even get the
next
one in line to power up stably (and you have to get into some very very
good
ones to do that, they basically have to be generator rated), then you
have
to deal with the issue of the other UPS'es in the chain not being 100%
efficient, so you lose a lot of what you would have gotten from that
first
unit in the line. This of course follows up the chain.


Doesn't the UPS just pass along the input to the output as long as it's ok
power?
So I don't see the loss. The second UPS just passes along the output of
the
first UPS.

On the internet, nobody knows you're a jerk.


Ron, No!

There power is checked to be sure it is 60cyc, close to 120 and steadies and
it is filtered. Read the papers that came with it. Remember, you get what
you pay for. I like "Minuteman".

For your radio the way I do it is run them off a 12v car battery with a
charger hooded to them. I can "take" the charger off if I hear Norse or just
when I am DXing. If the power goes off they will still run for hours if you
have a good battery and you can shut down the radios you don't have to have.

ALWAYS HAVE A GOOD GROUND ROD GROUND for the radios and antennas!
