"There has been no change to the ASTRA 2D transmissions. Possible cause could be an incremental level of adjacent satellite interference, because of additional transponders being operated at adjacent orbital positions. Repointing the concerned antenna's could be a solution."

I'm not sure that this reply is credible.  I'm no expert but I thought that the only adjacent satellite was Eurobird 1 at 28.5 ?  If Astra mean that there are recently increased levels on that (or on transponders on the Astra cluster) then a) they should know about it and b) dish pointing is so critical for Astra 2D that I would have thought that realignment away from Eurobird would not be possible without losing Astra. ?  Furthermore, would increasing dish size not amplify the problem of interference.  Please comment Nigel.
