If you are more confident that the method is inaccurate when it is operating then it being low spread is indication that it is not operating. A TV that shows a static image that flickers when you kick it more likely is recieving actual feed than one that doesn't flicker when punched.
If you have multiple TVs that all flicker at the same time it is likely that the cause was the weather rather than the broadcast
Can you clarify what youre talking about without using the terms method, operating and spread.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
