I must admit to have suspected cloud cover, atmospheric pressure and CTs of affecting hum at one stage or another- but recent clear skies and steady weather front has left hum on permanent idle drone.Noticeable mainly at night. No breaks- only a slight modulation if a second or so. This is 'Basic Hum mode' and definitely doesn't mean a clear bill of health over the other issues as they could be actually switching hum off (rather than on), by various means.[ie: as in low freq coding]. All the same , a useful observation for your particular area M&J .- I'm south central England. Great to see REALLY clear skies, for once. Makes it obvious what the layered CT flumes are doing... Colours look really bright too!
