So Bill was 'wright' again. ;-) Perfectly possible to get some of the
Astra 28 group but not all, if the dish is off alignment.

I think *all* bets would be off if the dish was out of alignment. ;-)

It's also not knowing what you can get away with.

Quite, something I learned very quickly whilst installing 10 satellite
systems. The first one took 'some time' to understand / get right then
after that I couldn't see why it took so long the first time. ;-)

On the dish bracket,
each degree marking is about 1mm apart. And the setting I got was 22.7.
With the pointer being about 2mm wide.

Yeah, great. ;-(

I sort of assumed with a 1 metre dish it would be pretty tolerant. Find
any one of the Astra group and the others would be OK. But not so -
obviously.

With a single LNB you only get a few degrees of latitude and I think
they are ~6 degrees apart ... so you could easily be 'off tune' for
some of the group if you were focused on one of the outliers (and
worse if you were on the edge of the window in the wrong direction on
one of the outliers).

Like using a torch with a very tight beam to try to light up your
whole back garden from the back door.

Multi Satellite is a fun step up from single Sat and both over
terrestrial DTV and that is the same from ATV. ;-)

The shame is (often old) people paying to have their new DTV 'set up'
when in many cases you just plug it in and follow the onscreen prompts
and it does it all for you (unlike the old ATV where you had to
manually tune each button and the video etc). ;-)
