I work with the SACTA everyday. If you have any practical questions, I may help, but I am not a technician, just an ATC whith basic software/hardware knowledge.

PD. By the way, I like the system. We have two nights ago changed (at the same time in the whole country besides Canary Islands !) from version 3.4 to 3.5, and there were some local problems, but worked well.
