Hello all:
            I�ve been browsing the web looking for information/schematics on
building a CI-V level converter/interface to use to control my Icom rigs. In
my travels, I�ve uncovered several circuits, some simply a handful of
components that can supposedly fit inside the hood of a DB-9 connector,
others considerably more elaborate, based on IC chips. Who of you have built
any of these, and what are the pros/cons of each design? Are there any
interface designs that utilize USB rather than a standard serial connection?
What about functionality? Do all of these designs support completely the
Icom CI-V format, or do some of these simpler ones fall short? Any
information from experienced builders of these interfaces would be greatly
appreciated.

Tnx es 73. de
