[Elecraft] KIO2 outside of K2

[Steven Pituch]

Hi all,
I noticed that the KIO2 option uses a standard conversion chip like the
Maxim 232, but does not use optoisolators.  I guess the optoislators would
not help when the KIO2 is inside the radio close to the other circuits.  I
also noted that the KIO2 can generate noise. Has anyone ever considered
using the KIO2 with optoisolators added outside of the K2 chassis?  My
limited experience with my homebrew interface for a Kenwood CAT says that it
would be much easier to eliminate the interference, and since the cable to
the computer is outside the radio, the RS232 interface being outside the
radio would not be much of an inconvienience.  Just a thought.

Steve, W2MY
