Graham,
     I don't know if the P3 can be interfaced easily with the KX3, but 
what I have been telling folk who want a good spectrum display for their 
KX3 is to use NaP3 and a good quality sound card.

     Elecraft was really smart by making the I & Q data available 
directly on the side of the radio. What that means is that all you need 
to do is run these two channels into the input of your sound card and 
run the software. You will now have a fully integrated display with your 
KX3 at a very reasonable cost.

     One of the reasons I bought the KX3 was my inference that I could 
do this. and, I was correct. NaP3 is a subset of the Flexradio PowerSDR 
software and is quite good. This allows you to use either the radioss 
audio or sound card's audio using the capabilities of the software. 
Which is best? Both. There are some advantages to each and I love them 
equally. My new sound card was $150 from Sweatwater delivered. I have an 
EMU by Creative labs, but that is a little temperamental on my Win7 64 
system, but it was only $100.

     You can make a P3 function with a KX3, I assume. But it is going to 
require some engineering and surgery. I think I would go with the 
simplest first as a trial. You might just want to stay with that 
configuration. Right now, there are at least 5 of us using the easy way 
and all seem happy.

73,
