Hi guys

i'm facing a little problem with my vu+ ultimo

i am using vti 4.1 image and i haven't tried yet any other but i will if needed.

the problem is that when i turn on the receiver it gets the signal fine but then i change to other satellite position and it gets no signal, even if i get back to my initial sat position it stills get no signal.

after moving to other position ive made a service searching and it gets the channels back, but if i move to other sat it loses it again.

is this happening to anyone else?
is there a reason for this?

thank you in advance for your help
