Subject: DRSI BOARD AND RFI

I recently had a conversation with DRSI, and in the course of things
the subject of RFI came up.  Here is some information you may find 
interesting and useful: The board is NOT GROUNDED THRU THE MOTHERBOARD,
BUT THRU THE METAL BRACKET.  (signal and electrical returns are, of course,
thru the motherboard, but not the connecting cable shield ground.)  This
is done to keep stray RF on the shield from being conducted inside the
computer case.  Those of you who don't always insert the little screw
may find that making a firm connection between the mounting bracket and
the case, and having the screws in the cover in place and tight, may
reduce or eliminate RF getting into the DRSI board and affecting the 
computer.  This also may reduce RF coming OUT of the computer, also.
