[Elecraft] Help on wiring up a XV144 to a KX3 (or KX2)

[Don Wilhelm]

Paul,

What I said refers to the KX3 only.   For the KX2, there is only a 
single TRRS jack instead of the KX3 ACC2 jack which is TRS.  So the 
wiring for the KX2 is different than what I specified.

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.
