Paul,
Your wiring from the KX3 ACC2 jack to the XV144 DE-9 connector is not
correct.
The ACC2 shield should wire to XV Control pin 1 - this is ground for the
XV144.
The ACC2 ring should wire to XV Control pin 9 - This is the KEYIN to the
XV144.
The ACC2 tip should wire to XV Control pin 6 - This is the AUXBUS signal
to the XV144. The KX3 ACC2 IO menu parameter must be set to TRN CTRL.
I have some questions about the level of this signal - the KX3 outputs a
3 volt logic level and the XV144 is expecting a 5 volt logic level. You
can try it direct (I have never tried it). If things do not work
properly, you will have to insert a bi-directional level conversion in
the path.
Actually the XV144 will work fine without the AUXBUS connection, but you
do need the KEYIN signal. Configure the XV144 for a non-Elecraft
transceiver and with the KEYIN connection, all will work fine.
Set all the DIP switches to OFF - those switches only respond to the
Power On the XV from the transverter. That signal is only available
from the K2 and K2, it is not available from the KX3.

I would like to connect these two and am following the guidance in Fred Cady’s
KX Line manual page 239 and details in the XV Owners Manual.
Wiring/connectivity is;
- KX3/KX2 RF out (28 MHz via BNC) connected to XV144 Tx In/IF1 port (single
port for RX/TX).
- KX3 ACC2 connected to XV144 CONTROL DB9 port
KX3 transverter 6 is configured
XV144 configured to be transverter 6 via instructions on page 5 of XV Owners
Manual (i.e as if the XV is connected to a K3 using the wiring outlined above.
Can someone confirm that this is the wiring I should;
- KX3 ACC2 TIP wired to pin 3 of XV CONTROL
- KX3 ACC2 SHIELD wired to pin 5 of XV CONTROL
