Yes, John, you do need a separate ACC lead wired as quoted by Gary as 
follows....
--- --- --- --- --- --- --- --- --- --- 8< --- --- --- --- --- ---
You need to use the DE-15 AUX I/O connector to interface with the XV144.
The auxbus line is needed for addressing and control of the transverter
(using its ADR setting and the XV's DIP switches). And the KEYOUT-LP
line is needed to place the XV into transmit mode, in the same way as
the 8R line does for the K2. So you'll need to make a cable like this:


XV DB9      K3 DB15

Pin            Pin

1 ground        5
6 auxbus        2
8 XVTR ON       7
9 PTT          10
--- --- --- --- --- --- --- --- --- --- 8< --- --- --- --- --- ---

My K3 settings for the XV144 are as follows...

KXV3     nor
XV1 ON   yES
XV1 RF   144
XV1 IF   28
XV1 PWR  L1.50
XV1 OFS  -0.89 (Yours may need to differ)
XV1 ADR  trn1

I hope that helps.
