but from following the weather a bit I've started noticing that it gets worse on the nice sunny days.

In terms of "thermal effects," could this be a thermal expansion effect that impacts your aerial's alignment?

Hamish.

I forget the correct term for it and apologies if its already been talked about but is your gear on different elevations? say 100m or more difference? People do get issues with thermal pockets of warmer or colder air, as RF passes through these thermal layers and voodoo magic(tm) sometimes happens.
