[Elecraft] Case for XG2

[Don Wilhelm]

  Dave,

My first (untested) opinion.
I don't think tape will get the shielding job done adequately.  I have 
had problems with leakage on some low level generators I have built 
through the power connections.  I would believe a die-cast enclosure 
with as few penetrations as practical is one of the few answers - 
another answer is an enclosure fabricated of PC board and a soldered on 
cover with a feed-thru bypass cap for the power.  Take a look at one of 
Wes Hayward's low level generators on page  7.18 of Experimental Methods 
in RF Design.

Levels in the -130 to -140 dBm range are VERY low, and even a small 
amount of leakage getting into the receiver under test will cause skewed 
readings.

73,
Don W3FPR
