Cheers all, some good advice there, not looking forward to trying to improve the dish alignment.
Our pic breaks up far too easily, so thought I'd replace the LNB as a starting point, then move on to tweaking the dish.
Ive got one of those little satellite stength meters, but have read conflicting reports, some saying they work well for the whole job, some saying they get you in the ballpark, then use the one built into the sky box to fine tune.
Most the ones on ebay report to be a direct replacement for sky minidishes now, so should just be a case of getting the settings off the old one and applying to the new, swap the cables etc over, and away we go.
Be a few weeks off anyway, as there is a birds nest behind the dish at the mo, and Im not going to disturb the eggs.
The cheapie LNB meters work off IF Signal so the pretty much realtime but can be a bit hit and miss and all or nothing, the Sat receiver will show RSSI or Captured Data or a mixture of both so a slight movement in the Dish could give the reading a second or two later.
An old Analogue trick was to, once you've found your best signal, tape a 1p or 2p over the center of the LNB to reduce signal then go for maximum signal whilst tightening up the bolts etc.
And it may sound silly, but, dont forget take the coin off when youve finnished.
Chris.
