Any one help me this

Reduce your power level to 18-19dBm.

I doubt reducing power on such a long distance link would help all that much.

You doubt?

Not only does his link look miss-aligned, but he also has posted (in another topic) a much higher noise floor. Yes, he might be able to optimize his link a bit more if he were to drop TX power, but I think there are other issues present that will effect the link more substantially then dropping TX power at this time…

Here is the Mimosa manual about optimizing TX power and some of the benefits of doing so, just for information to other reading this Topic.
