pixelating on locals

[Patricio71]

Hi all, I've been using a (US) dish 500 here in Northern Mexico, only 60 miles south of the border for several years. Recently during the heat of the day I get serious pixelating or no receptiona at all on ONLY MY LOCALS. Everything else is fine. After sundown things settle down and the problem disappears. Only the locals are affected. Anybody know anything?

Your LNBF is heating up during the day and is causing what is called LNB Drift. You need a new LNBF.
