9 9 Quiet Skies Project and IYA Two Flavors: 1. Be an Interference Detective : AM Radio Scavenger Hunt of any interior space. Can be “Try it at Home”, or guided activity.  Limited to AM Frequencies.

10 10 Quiet Skies Project and IYA 2. Quiet Skies Kits:  Contain sensitive instrument which can detect RFI at Frequency range of 800- 1700 MHz ( scientifically interesting).  Loan program. 500 units x 10-20 locations throughout IYA.  Measurements reported to NRAO data base resulting in… the radio version of…
