[Elecraft] K3 DSP board improvement(s)

[Ken Kopp]

Some may recall a problem with overheating / failure
of the audio IC on the DSP board when a mono plug
was plugged into the speaker jack, creating a short
on one side of the chip's output.  I'm aware of several
chip failures ... including mine ... due to this "operator
error".  

In conversation with Elecraft yesterday I learned that
the current DSP board has additional "land" on the
upper edge of the board that provides additional heat-
sinking for the audio chip.
