A serious thunderstorm somewhat counted / 2016-06-23

Last night a serious lightning storm passed and it got counted, but clearly with the same problems in counting as seen before in counting thunderstorms from the shed while radio activity causes a lot higher counts. Looking at the graphs for thunderstorms counted from the attic before I was active on HF radio there is quite a difference in numbers.

I think I want the lightning strikes counter back up in the attic but with a low-pass filter somehow to filter out false counts from amateur radio traffic.
