Fred - What channels are you talking about? What sat? and what's your setup? Viewsats did not have channel losts reported, so I'm not sure I understand your question.
I am talking about some arabic channels on sat 61.5, it keeps saying "searching signals" on bunch of channels in 61.5 sat Nobody else is having this problem in viewsat ??
Have you rescanned that bird. Loading a new bin doesn't hurt (well unless it's that other receiver)! But I wouldn't hesitate loading it and rescanning that bird...
