Hi Ben,

As I'll be explaining in the next edition of the owner's manual, the 
XVTR ON signal is just a DC voltage that's present when the K3 is 
turned on. It doesn't turn on only when you're on transverter bands, 
and really should be called something else (like "Hey, I'm on!"). It 
behaves the same as the related pin on the K2's 9-pin connector.

If you need to use this pin on the K3 for TX INH, instead, you can 
still get a functionally equivalent "XVTR ON" signal by using the K3's 
switched 12 VDC (at the accessory output RCA jack). Just connect it to 
pin 9 of the transverter control port. You can use a series resistor, 
say 1 K, since very little current is required at the transverter to 
turn its MOSFET power switch on.

I'll be including full details for the K3 to transverter interface in 
the manual. Sorry for the delay.
