8 Quiet Skies Project and IYA 1.Conduct “Be an Interference Detective” Activity in your museum, school, scout meeting AM Radio Scavenger Hunt of any interior space. Can be “Try it at Home”, or guided activity.  Limited to AM Frequencies. How Can You Get Involved?

9 2.Measure RFI in your communities using Laptop and Xirrus widget  Download free widget and install.  Measure RFI from wireless hotspots!

10 3.Borrow Quiet Skies Kits:  Sensitive instrument which detects RFI at MHz (scientifically interesting).  Loan Program: 20 units in the US, each unit forwarded to locations throughout IYA.
