Heya,

So my Skybox F3 was full and couldn't take anymore channels so I reuploaded a TV_PROG via the lan tool like I've done before without issues, but now when I scan in channels they list twice under the same frequency but one for vertical and one for horizontal! :(

I checked the LNB setting and it's set to Universal 9750-10650 which is what my other one is set to. So I'm a bit confused whats happening?


Thanks

Isn't this a typical symptom of using a circular polarized LNB for a linear transmission? I stand open to correction....

Hmm well unless someone swapped it out in the night the LNB is linear. :D
 
My F3 has started showing a few odd quirks as well.

After scanning 42E & pressing ok to access the channel list it defaults to the all satellites channel list. This is the only bird it does this on.
 
Clutching at straws - how about the skew being out by 45°? Unlikely considering you're motorized, and that would cause you all sorts of other problems (poor reception across the board for one).... I have a few Megasat single LNBs (I forget the exact model) where to set a skew of zero you have to turn it 45° to the left so that the cable ends up pointing out in a half-past-four direction (looking at the LNB from behind).
 
Some Icecrypt and Fortec Star (FSUKVN) LNBs exhibit that odd characteristic >> Well documented here.
 
Maybe it is not switching the voltage between 13 and 18, or vice versa. That would mean that when the box thinks it is scanning horizontal it is in fact scanning vertical, which would give 2 copies of the same channel.

Yes, but in that case would it not be missing half the channels?
