I just wonder if someone can explain me something here..

Amplifying a signal will nessacerily make a imperfection to it, as all amplifiers I`m aware of does.
Never heard of a device wich boosts a signal without making a small amount of imperfection to it..
Stronger yes, but not as clean as before.

And as the range increases, the original signal will nessacerily be weaker.
How come is this amplified signal a better guide for the servo, than the original, when we add a imperfection to it?
Is it because of it`s reached base width (like compared to a signal on a frequency scanner), wich still is in a acceptable shape?

Would have been fun to see on a ozziloscope..

I`m only asking to learn about it, whats why I`m asking the way I do.

Underlining, my oppinion is just that, and based on couriosity alone. None of my "souspicious" questions are related to place any manufacturer where they won`t find themselves comfortable.. (!)
