[Elecraft] KX3 + XV432

[Don Wilhelm]

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.

73,
