Hi Jack,
With my limited knowledge from scratch building an rs232 interface, I
thought it might be better for the interface in the K2 to be outside the rig
for isolation purposes.  I thought the farther away it was from the xcvr the
better things might be.  However, you have shown me that I was talking about
a different type of problem with regard to the optoisolators.  My plans are:
1)to update my K2 #402, 2)add a KIO2, 3)do some digital QSOs with CAT
control, 4)eventually add the KPA100 inside the K2 enclosure, and eventually
5)remote the KPA100 and a KA100 in an EC2 enclosure.

Which brings up another question.  Is the remote KPA100 option approved by
Elecraft?  I see that people have done this, but I haven't found any actual
Elecraft documentation on it.

Steve, W2MY
