Hi, Bob:

The first thing I see is that mountain in the signal path.

I don't know if it's the weather (heat) that is causing this or the stations having xmtr problems.
Temperature inversion can affect the signals on their way to your location, by keeping them from bending down by refraction toward your location after crossing the peak. Is it worse during the day?

The affect can vary according to the frequency of the channel.

What antenna are you using and where is it located?

Are you using a preamp?

Any trees in the signal path?
