Skadi, the First Transceiver
John Lawton, an electrical engineer and pilot, was employed by the Cornell Aeronautical Laboratory in Buffalo, NY, USA. In his spare time, he did voluntary work as a ski patroller at a nearby ski area.
Together with a colleague, he invented and patented the first transceiver. It was named the Skadi (nicknamed "Hot Dog") an operated at a frequency of 2.275 kHz.
The word Skadi comes from the old Norse word Skaði, variant Skade. This female is often referred to as the goddess
of skis; she traveled on skis, carried a bow, and hunted.
She was the daughter of the giant Thiazi, and married Ullr, the god of skis.
