Radio Broadcast theory when he leaves as operator on Donald MacMillan's Bowdoin on June 15th of this year. Extensive experiments are to be carried on with daylight transmission on 20 meters while the ship is in polar waters. Mr. Reinartz as operator, has been appointed to the place held by Donald Mix aboard this ship on the previous voyage. Mr. Mix is also a member of the American Radio Relay League. Both those appointments show beyond question the value placed on amateur talents. For a number of years American amateurs worked with all of their might to send their signals across the Atlantic ocean. Their final success marked the real beginning of international amateur communication for it was not until that time that the future possibilities of low power and short waves were fully realised. Their next task was so to perfect their instruments and method of operation that they could exchange messages at will with private individuals in various foreign countries. Immediately that two-way communication was established between amateurs on opposite sides of the ocean, interest of operators in this country reached a high state of enthusiasm and amateurs began to spring up here and there in countries where they had never been heard of before, until now they may be found dotting almost every part of the world. Three or four years ago American amateurs kept before them constantly a wall map of the United States, while now in these same radio shacks may be found world maps and globes. With one kilowatt of power and a barrel of enthusiasm, amateurs threaten to conquer the three obstacles to radio communication, time, space, and daylight, using short waves that once nobody tnought were of value.

Note the wall map of the world, dotted with colored pins, showing the various parts of the world in which 6 awt has been heard. Ten years ago, distance records such as these would have been considered an absolute impossibility
