[Elecraft] [K2] : Laptop UPS

[Brett Howard]

Yea the ones that qualify have to say Efficiency Level IV on it (or
something like that).  Essentially some European group did a study and
stated that if you took the passive load of all the unregulated bricks that
are in Europe it would total up to one power plant or something like that...
I wasn't paying too close of attention as I usually just splat down the same
supply that I used prior unless I can find something cheaper.  In which case
I usually follow the app note and the demo board and all is well...  As for
the brick its just one more requirement that I have to make sure we get
taken care of and that we get the brick labeled properly for all the
regulatory garbage... :)  But yes California heard about this and was like
wow if we get rid of all those passive loads from bricks that are plugged
into products that are turned off we'll save all sorts of money.  That and
the power system in CA already seems a bit "fragile" at times....  Works for
me... Oregon makes quite a bit of money selling power to you guys!! :)

Oh, great.

Although as you point out it is possible to make a quiet switcher, it's 
also cheaper to make one that will wipe out everything for a 100-yard 
radius.  Let me tell you about this high-intensity lamp that I 
have...actually, it does have some value; it can be used as a noise 
generator to align the filters in my K2.

Now *every* piece of electrical junk will have one!
