[Elecraft] Non-Elecraft Transverter use with the K2

[K8RS]

VHF/UHF enthusiast,
          I would like to hear from anyone who has used their K2 with a
non-Elecraft transverter.  How did you do it?   Did you use J13?  Has anyone
tried DownEast Microwave's TIK2 board?
           I have a DEM 903 MHz transverter that I want to hook up to my K2.
The J13 female header looks like the spot to use, but how does the DEM TIK2
work there?   Especially, since the revision B boards have already taken 8T
off J13.
           Scott from Elecraft is looking at the DEM TIK2 documentation for
application.
                   Thanks,
                               Roger K8RS
