[QUOTE="nopfusch, post: 136314, member: 195487"] [color=black]Hi to all interested,[/color] [color=black]unfortunately, not all manufacturers state the tuner specification in full either on their sales pamphlet or in the manual. In the latter you find the specification in question under Tuner. I attach three samples. But the support sections of various manufacturers should give an answer about that vital parameter of a receiver, if that spec’ is missing. I contacted in the UK a company to enquire about the input sensitivity of the tuner of a product and received promptly the answer. [/color] [color=black]The manufacturer state usually a range, e.g. -25dBm to -65dBm. Reason: if a receiver receives a very strong signal, you see nothing. If you in center of a strong footprint with a big dish, the tuner 'blacks-out', I have been told. I have seen it on TV sets (terrestrial reception) but not on satellite receivers. Therefore -25dBm. The other limit is of course for us of more interest. But we cannot verify if [i]that[/i] receiver really handles a weak signal of -xxdBm.
