This is going way out there what happens if you turn your radio 90 degrees. Last month I had a client who was installed wrong. Tower was Horizontal and guys setup the radio vertical but it worked and they did not know any better. I got checking the tower later and saw the client was -79 at the tower. I called them in Chewed them out for installing wrong and sent them back. They followed my orders and the signal at the tower dropped to -59 I turned down the radio and stabilized it at -69. I was happy. Next day the customer called and said could we come back and fixed what we had changed. I started them doing pings and they were terrible. So I drove out to the house. Messed with it for 1/2 hour. Climbed to the radio turned it back to the Wrong Polarity and set the power back and the speed and pings were perfect. I came back to the office walked in the door and there was my installers standing there waiting for an apology. I smiled, shrugged my shoulders and yelled "G et back to work" Moral to the story if it's a very close install sometimes it is too close and you need to make the radio work harder on a wrong polarity.

It looks like the sun is shining and 65 degrees in Salem. Sun beating on that metal surface can cause heat waves to rise in front of the antenna causing scintillation. Sometimes this stuff is black magic and moving a CPE a couple feet one way or another can make a world of difference. No trees or branches in the Fresnel zone waving in the breeze? I'd try adjusting the tilt as suggested, them putting a pipe section in the J mount and moving it up 2.5' or so. Hope you figure it out. Let the list know.
