A Picnic Table, Two Watts, and a Binaural Recording of an Irish Forest
Parks on the Air pairs a transmitter with a location, and EI3LH's write-up from County Kilkenny is a good demonstration of why that combination is more interesting than either half. Twenty-seven contacts from a Millennium Forest, four countries on roughly two watts from an uncharged battery, and binaural birdsong from the evening park.
