Ok, I'll try to use high TC and to wait for the result
Before I've being refering in my mind to Stoianm's videotutorial, where he after the mission start mooves in couple of minutes to hydrostation and detects the target-ship immediately
So may be he made some cuts of his moovie or some other "producer's tricks" in order to safe time, who knows
Anyway, thank you, Trevally, and do not bother with this issue anymore - not worth of it
The tutorial is working - and that's fine!
