In the last few days some of the frequencies used by Sky TV have changed their frequency settings.

They have changed their FEC from 2/3 to 5/6.

The frequencies affected include;
12207 V 27500 5/6

11914 H 27500  5/6

and

12148 H 27500 5/6

The FEC is the Forwards Error Correction,  and tries to eliminate errors and missed data during transmission, which results in picture breakup. By increasing the FEC (say from 2/3 to 5/6) then there is less allowance for errors, freeing up bandwidth on the frequency. With more bandwidth on the frequencies, this can allow more channels on that frequency.

BY doing this however, there is a reduction is signal level, and so some areas may see a loss of these Sky pay channels.
