This past weekend was the Amateur Radio Field Day around the world. Here on Maui, they set up in a cow pasture near Hookipa Beach overlooking the ocean. Once a year, the local group join others and run tests for 24 hours. They contact other radio operators across the globe.

For those of you who don't know what HAM radio is, amateur radio operators use a layer of the Earth’s atmosphere as a mirror for radio waves. Marconi invented it. It is a way to communicate with people when all other communication devices don't work, like cell phones, internet, house phones.
When I was a kid, my Grandpa Don would come home from work and spend hours trying to "dial in" to other operators around the world. He had a desk set up in the living/dining room with a number of radios on this big table. He used a microphone to speak and had to listen hard for a voice. I remember watching him and hearing the scratchy voices of people from distant lands. It was like magic.
A very fond memory every time I drive past the cow pasture.
Thanks for Listening.
