Well, the lights started flickering again. In attached, CB 1 & 3 are a signal unit - tandem I think is the term. I removed them, cleaned all the contacts and checked all the wiring connections and all are fine. After that, no flickering for a few weeks. Now it started again this week. Connections are still tight.

No other devices are flickering. Wind doesn't make any difference, so it sounds to me like it's in the CB 1& 3 circuit. The ceiling light/fan in slot #8 doesn't flicker, nor do any lamps plugged into receptacles.

Any other ideas what might be the problem before I go out and buy a new CB?

Thanks fellers!
