DIY Freesat follow up
 

Earlier this year I started a couple of threads concerning my venture
into Freesat and putting together an HTPC.

All has gone very well and for a couple of months we have been
receiving Freesat via the 60 cms dish and the HTPC running WMC with no
problems except for the occasional picture break-up on BBC2 HD. Have
tried retuning the channel a couple of times but still get the
occasional problem.

Is there any reason why just this particular channel would cause
difficulties?

Most likely the dish alignments a shade marginal..

Or if your that far north you ought to have a Zone Two dish its a bit
larger..

Alignment is something for me to look at - I just thought that if it
was a case of alignment that more than the one station would be
causing problems.

Located on the coast in south Devon and I was under the impression
that 60 cms was a zone 2 size, but I could easily be wrong.

We notice no problem, but perhaps it is on a busier transponder than BBC1
HD.

Use the 'wet tea cloth' method for DIY alignment.

Small dish OK there.

Not the case as some sats are in -slightly- different positions.

Normally the dish would have sufficient "pickup gain" to "see" them but
if its just on edge as it were..

I understood that BBC2 HD was on the Astra 1N (28.2°E) satellite,
together with the majority of the other BBC, ITV and Channel 4/5
stations.

The dish is a Primesat 60 cms, which is not a sky minidish type.

I used Java Jive's excellent alignment tool together with a good
compass and a meter but I would be more than happy to try the 'wet tea
cloth' method if you would expound a little.

Small dish OK there.

Is it likely that a larger dish eg 80 cms be of benefit in this case?

A related issue is that of CCI from another satellite. Slight
misalignment often shows up as a mysteriously poor BER on one or more
muxes, and it turns out that signals from a sat a few degs away is to blame.

Exacerbated by the fact that an LNB offset from the prime focus will
exhibit some astigmatism, or whatever the RF equivalent is called.
