Dan,
That looks like it should work fine.

Thank you, Don.
I think I have the Elecraft cable for the Keyline output/ACC2 as it
came with the cable pack that I purchased.
>From this lead, I would connect the RCA to the RCA amp port on the
ARB 704 interface as the buffer step between the transceiver and the
amplifier as is the case with my base station, correct?
Can you confirm that this will isolate the KX3 from the amp and not
cause any damage to either? Under normal/best case circumstances.
Does this look right?

Dan, The KX3 has a KEYINE OUT output which will key your amplifier. It
is on the ring contact of the ACC 2.5mm jack. See page 5 of the KX3
manual. When you add the KXPA100, there is a "black box" on the KX3 to
KXPA100 cable set which brings that KEYLINE signal out to an RCA jack.
See the KXPA100 manual. So if you have only the KX3 now, you will have
to build a cable which takes the ring contact of a 2.5mm stereo plug
out to an RCA plug which you would connect to your amplifier. The KX3
KEYLINE output is rated to accept up to 30 volts and up to 100ma. 73,
