HI Yuri et All.
I think I have solved the 599-to-panorama.
Thanks to Yuri advice to turn ON the RIGSYNC tab in the SDC setup fields and after some more time spent in thinking HOWTO click-around
I have succeded to get it working with my combo: FT1000Field+COLIBRI_Nano ... ah of course the PC itself.
See the attached screen-crop.
Four main steps are needed:
1) activate RIGSYNC in the SDC SETUP,
2) activate one SYNC_CHANNEL and RIG_CONTROL1 with TCI CLIENT and name it COLIBRI (just in case one forgets...),
3) tick OMNIRIG CONTROL on the right, I hope you are using that interface to the CAT.
4) tick SEND-RST-599 to panorama in the GLOBAL SKIMMER SETUp,
and last activate the SPLIT on the TRX.
What happens : by clicking the 599-to-panorama it lets appear the square-brackets showing the PILE-UP limits and activating
the SPLIT button on the TRX activates the secondary VFO bar in the Colibri and it gets chained to the TRX_VFO_B.
Of course in the EESDR soft the VFO_B audio-mixer level must be set to any comfortable value to let hear the stations in the splitted part
and in the SETUP_SKIMMER UN_tick DECODE VFO_A and tick SEPARATE-WINDOWS-VFO A+B .
I hope this short notice will be of help to anyother who comes for the first time in such "complicated"

situation.
One last notice: after having replicated some times to be sure that such procedure works, now the SPILT function opens with a light-red shadow
on the right side ( ONLY IN 160MT,see on the left under ON4AWX call) and do not know how to get it away. Sure Yuri will know that.
