I can live with trimming the motor up. The only question I have left is why the right return seems to be stronger than the left return. I say this because the usable range seems to be greater on the right.
I have attached pictures on the install. Some are fuzzy....sorry. I was thinking that maybe the brass drain plug is bouncing back a signal. Would this explain the solid line that you can see in the screen shots just left of center? If so, could this cause the rest of the signal to be diminished resulting in less range on the left side?
I can live with the current results....but I would liek to perfect it if possible.
