[QUOTE="M60, post: 933252, member: 376177"] What you have to also consider with these latest migrations this morning is, like all the other E28A ones, the co-channel H/V TP allocations degrades C/N and quality due to LNB crosstalk. Different LNB's will perform differently in this respect but would envisage it to have a clearly noticeable difference on the fringes. I'll do some C/N and quality measurements tonight across these new TP's to see what the improvement looks like here in the UK. I know previously anything close to 8dB C/N was considered good here on E28A, the C3 and C4 spot migrations saw C/N go up to 15.5dB on one of the TP's with the rest between 14 and 15dB. Will measure the 2G migrated TP's too as not checked those yet. [/QUOTE]
