Interrupted TV broadcast signal on both kqed and kqed plus

HELP PLEASE!!!! For the last two weeks my excellent signal reception (dish roof antenna) has suddenly become constant terrible and impossible to watch: "fail to receive" "no broadcast at this time" distorted pics, lines, dots, scattered sound bites. What is going on??? Problems at SUTRO broadcasting again? FYI-- channel 4 is constant "fail" and channel 65 is responding same as 9 only worse. Tonight July 3 I'm getting a solid fail for the last hour since 8:30pm.

Starting two weeks ago the local Foothills Amateur Radio Society was/is preparing for the Annual Amateur Radio Field Day. (Since over ten years ago, a close by ham operator using an extra strong signal was the source of our TV interference, I've tried to follow up through their organization but have no response yet.)

I'm on Vineyard Dr. in Los Altos and a sustaining kqed member. Jackie S******s
