Ken,
There is something strange going on. Does the XV432 stay in the receive
state when you remove the RCA plug from the KEYIN jack on the XV432?
You have two things to work with - both the KX3 and the XV432, and both
should be set up properly.
If you are wanting to use the KEYOUT from the KX3, then you will have to
configure the XV432 as non-Elecraft. That means a jumper on JP7 and
*no* jumper on JP8. You will also have to have all 4 dip switches set to
OFF. The XV432 will be active when the power switch is on.
If you have a sufficiently high resistance at the XV432 KEYIN jack, the
transverter should be in the receive state, and it should go to transmit
when the KX3 is set to transmit.
You can still set the XVn menus in the KX3 to the proper frequency,
drive level, etc. so the KX3 shows the XV432 output frequency when you
switch the XV432 on.
That is the easiest setup.
Are you certain you have plugged the 2.5mm ACC2 plug in all the way?
Give it that extra push to fully seat it.

I'm trying to complete the alignment and setup on my newly completed
XV432. I'm going to use it with my KX3.
I made a cable so the KX3 can key the XV432 to transmit. RCA phono
plug at the XV432 and a 2.5mm stereo plug for ACC2 on the KX3. Center
pin on the phono plug connects to the RING on the stereo plug.
Whenever I connect the two units together with the cable the XV432 go
into transmit. If I unplug it from the KX3 it goes back into receive.
I checked that only the RING and ground are connected at the stereo
plug. I have checked for shorts (ring/center pin to ground) and
continuity (from ground to ground and RING to center pin) many times
and everything is OK.
With the cable plugged in to the KX3 I measure infinite resistance
(open circuit) across the phono plug.
The RING terminal is not affected by ACC2 IO menu settings.
My understanding is that the keyline goes low during transmit,
according to the KX3 manual. It's not low when I check it on receive,
but it still keys the transverter when I connect the two of them
together. I think I've covered all possibilities, but they aren't
working together the way they should.
Anybody have any ideas. I'd appreciate any help.
Thanks and 73,
