[QUOTE="vma, post: 994734, member: 256592"] Hi, When I mentioned corroded F-connectors, I was referring to the end that attaches to the LNB. Corrosion can sometimes cause weird effects, like filtering some frequencies. Other possible causes might include: - Defective LNB - Interference (should however be present on the other LNB’s, too) I am sure that this is not coming from the satellite itself: the noise floor has to be similar than the remaining frequency band, but it isn’t. Best thing to do is to a) check connector and cable and b) replace LNB. Regards, vma [/QUOTE]
