First off, idiot. This is Usenet, so do not change the follow ups to
email, retard.

Which, in a digital realm, gets rejected.

Which, in a digital system, gets rejected. When is this going to
sink in, dude?

My gain dial works from around 40% all the way up to the full 100%
of the 12dB gain it is capable of.

You are talking apples and oranges now.

I am not surprised. You can't even get Usenet right.

Oh well. Should have bought a name brand then, I would guess.

You probably don't know how to cut a simple F-fitting.

You are lost. Your cable company is the only folks that can test
the power of their feed. You more likely had problems with your
terminations.

You ain't real bright. The cable modem requires a strong signal or
it will fail.

Again. I suspect the cable you were using.

It apparently matters not, eh?

I say that you are talking about over the air signals and piped
signals. Again... apples and oranges. Nothing you stated
definitively proved that you had too strong a signal in the coax. How
can you have such flawed logic?
