I am trying to help a friend with his FT-817. He is trying to hook up
a keyer to the unit. The manual shows a picture of the proper hookup for
a straight key/keyer and for a set of paddles, to use the internal keyer.
The straight key/key hookup shows a 2-conductor plug and the paddle
hookup shows a 3-conductor plug. All this makes sense and the keyer
cable was wired to a 2-conductor cable. However, it doesn't work. The
keyer keys other units just fine.

But if you go to the instructions for enabling the CW mode it specifically
says "3-conductor plug" in the section for a straight key/keyer. This
conflicts with the hookup diagrams. Which one is correct? Should he be
really using a 3-conductor plug for all hookups? If so, where should
the wiring go?

I have not had access to the FT-817 yet so I don't really know if
my friend is setting it up correctly, but I am still curious about the
discrepency in the instruction manual. It may be that he just didn't
set it up right and this is a non-issue.

Any help?
