In my previous bulletins i have mistake the design of the IF-UNIT
layout indicating a wrong position of the jumper to cut. This was
a cause of trouble to some OM's making this modify.
My particular thanks to F5NWK (Tanguy) wich have notice the mistake.

So I resend the correct modification with the correct layout.

FT-767GX MODIFICATION FOR 9600 BPS OPERATIONS
---------------------------------------------

- Remove the bottom cover of the FT-767

- Remove the bottom cover (8 screws: 4 underneath, 2 on each side)

- Locate the IF-UNIT board. Is the biggest one of the two cards.

- Once locate the components (jumper (A), resintances R39 (B) & R251 (C) and
  the connector P86 (D) connect the point (A) to the point (B) and the point
  (C) with the point (D).

Once you have make this simple modification you can connect yor TNC
to the DATA IN/OUT jack, to the rear of the FT-767 as follows.

             +------------+
stereo jack  |            |-----=---=--\
   3,5 mm    |            |-----=---=--/

                            |     |   +--- Data in (from tnc)
                            |     +--- data out (to tnc)
                            +--- ground


Well that's it.  You are now ready for 9600 bps operation on your
FT-767GX.  If you have problems, reply; I will try to answer your
questions or solve your problems about this modification.
