Conducted as an experiment by pioneer amateur radio operators, these messages, which were originated by citizens in Los Angeles, were sent to a station in Denver which relayed them to young Corwin in Jefferson City. He in turn passed them on to a station in Albany, New York, from whence they were forwarded to their destinations in Hartford, Connecticut. He repeated the experiment in more dramatic fashion ten days later, conducting the first successful two-way transcontinental relay whereby a message was started from the east coast, relayed to the west coast, and an answer received back on the east coast within a span of eighty minutes.
