[amsat-bb] HDSDR & SatPC32

I'm trying to get HDSDR, which is connected via CAT & Omni Rig to my KX3, to then be controlled by SatPC32 via DDE. In the Options menu of HDSDR I selected DDE to HDSDR and selected SatPC32. The result was a green connected message and smiley face so I assumed all would work. However when I select a satellite on SatPC32 nothing what so ever changes on the KX3. Am I trying to do something that is impossible with the KX3?
