- DIY mystery box will wow your friends by hinting at what the ionosphere is up to
Mirko Pavleski built a DIY device that measures ambient RF energy across the shortwave band, which can be used to determine propagation conditions in the ionosphere. The device uses an Arduino Nano R3 and a CA3089 chip to translate raw RF signals into data. This information can be useful for shortwave radio enthusiasts.
