[Elecraft] Plexiglas case for K2

[Ron D'Eau Claire]

I'd like to pass along an off-reflector comment Wayne made to me after I
wrote that there probably wouldn't be any RFI issues:

He wrote:

"Uh.... don't I wish  :)

Without the case, you'll see significantly more leakage radiation both 
out of and into the box. It varies a lot, but the box really helps, for 
everything below Microwave frequencies. Those can sneak in sideways.

But at QRP levels and in isolated situations, he'd be perfectly OK."

So there you have the "word" from the man himself about operating with the
plastic covers. Of course, the standards (and needs) of RF shielding have
grown considerably since I ran half a kilowatt on 20 meters using a rig
built on a sheet of masonite <G>. So has the sensitivity to RF energy of the
stuff we have in our homes and shacks. Back then I'd never dreamed that a CW
QSO might be interrupted briefly by the "krick, krick, krick, brrrrr..." of
the data from my cell phone updating the local cell tower sneaking into the
K2 audio channel. 

Personally, I wouldn't hesitate to fire it up QRP when it's being displayed
for people although I'd keep the metal covers on it for normal operation in
the shack.

It IS a beautiful display job, worth of recognition! And, from what I can
see of the boards, a build worthy of being displayed!

Doug,

  They belong at the top of Elecraft's gallery.

 I thought only of using glue to make a plexiglass
enclosure for my chess set (so that the cats don't
spoil it).  I have the pieces cut - now I'll try
to use screws as you seem to have.  Thanks.
