here in Oklahoma we new storms where coming so i got ready to watch the lighting detector i added on to my system. had it about two weeks before we have any lighting, as i watched the storm move in i got my first reading said 25 miles away, next 15 then 5 miles, then 1 mile as the storm rolled over head and lighting over head still read 1 instead of 0, it counted 187 , as it detected a flash it then blink off said interference not detecting, after a second it would then show listening, it would count a flash then go blink off showing interference and so on. anyone seen this happening before is this the norm. but the other thing i think is a flaw is when the storm moved off and out of area it still said 1 mile detection, miles never went back up moving away , at this point it still showing 1 mile as last detecting and listening as it should,
