If you are a member of netc.com you can look at the history by clicking...
"Click here for data charts"
in the popups for each station.
I have one in my living room (GM-200/Pi) that hasn't been moved in almost 2 years so it should be real, historical data. My station history is currently listed for one year

.
Very cool easy to use stuff.
Membership is easy!!! and I (personally) like the fast and easy to understand data.
Buy a counter setup and get 1 year of free charts.
Or...
For $20 get em without a unit.
Your money funds these projects!!! We answer to noone but ourselves. I have no affiliation with any products, I'm fighting for my grandchildren's future!!!
