[Elecraft] K2/100 RS-232 Noise

[Don Wilhelm]

David,

It is usually best to fan-fold the cable so it entirely tucks up into 
the corner at the top of the control board - and do the same thing with 
the speaker cable.  Removing the right side panel to dress the cable is 
the easiest way to accomplish the feat.

Keep the cables as far away from the KSB2 board as possible.

73,
