First thanks for this beautiful image. I have VU+ Ultimo 4K and I updated it to 3.0.9 by USB then by addon panel online. It has a twin FCC tuner and one single DVBS2 tuner for blind scan only. I disconnected all cables from FCC tuner and I made a blind scan on single tuner. All available transponders found and also channels are showing perfectly. But when I change cable from single tuner and connect it to twin FCC tuner (after turning off receiver completely by removing power socket and with its LED off), and then I configure FCC tuner setup correctly in the setting menu (I changed single tuner to no connected), some transponders have no signal (0) but some of others have (Full HD). When I connect the cable back to the single tuner (with proper configuration in the setting menu), I can see those channels correctly. I think my tuners are OK, but why this is happening??
