[QUOTE="pjgregory, post: 514694, member: 288654"] Hi All I fully agree with the idea that the BBC should offer subscriptions to people outside the UK who want to recieve BBC1,2 etc, but I fear that this will not happen any time soon. It all seems to be related to sports rights. The BBC buys rights for the UK only, which is why they are doing everthing possible to limit coverage. In the mean time - back to the big dishes. [B]Analoguesat[/B] mentioned trying to measure the signal from Astra 2D with a spectrum analyser. This is currently below the noise floor of my Spectrum Analyser with the existing dish and LBM. I have had one idea which is to look at the signal strength of Channel 4 at intervals during the day. As I said, I lose this in the evening, so I should be able to work out what is the minimum S/N ratio for lock with my existing dish. If my 2.4m IRTE dish gave the specified 46db gain (which I very much doubt), then I could work how much extra gain, and hence how big a dish I would need to get Channel 4 all day long. Channel 4 is on Astra 2A North Beam Tp24 at 12.168GHz. According to the reception map from Astra, I should be able to get all of the 2A North beam signals with a 1.2m dish - but here I am having problems with my 2.4m dish! Could it be that the 10cm misalignment due to the warpinging is reducing the effective size to below that of a 1.2m dish? So these are the two questions 1. Has anyone measured misshapen dishes and worked out just how much gain you can lose?. 2. Has anyone measured how much weaker Astra2D is compared with Astra 2A north beam in any location near me? If I can get answers to these questions, then I can start to assess the dish size needed for 2D reception. PJG [/QUOTE]
