Looks good, Steve,
I did something similar a number of years ago. I put a low power DEMI
xverter in a pair of K2s but ended up with a birdie that was pretty
loud near 145.1 MHz where we had our microwave calling frequencies. I
ended up removing the xverter and put it in a different enclosure along
with band switching to select up to six different transverter bands all
selectable from the keyboard of our logging program. It was great for
home station use, but having 144 built in to the K2 box is a nice
feature for roving.
With our transverter idea, we bypassed the K2 PA circuits and used a
lower power takeoff point for TX. It drove the transverter just fine.
As I recall, we had a switch on the K2 to select the low power takeoff
mode.
I hope to work you some more on your roving trips. I missed last summer
due to an extended illness, and only recently have I been well enough to
be active with hamming again.

For a while now I've been working on a project to install a low power 2 metre transverter
inside an Elecraft K2, in order to use it as an IF transceiver with transverters for the
microwave bands. I got it done this summer and used it on 10 GHz during the ARRL 10 GHz
and Up Contest, as a "plug-and-play" replacement for one of my aging FT-290Rs.
I have just finished writing this project up, as it may be of interest to other
microwavers. The description is at

Happy reading!
