New Paths for the Short Waves
by no means been exhausted was demonstrated recently by. two important events, one of these being the decision of the Navy Department to seek the cooperation of American Radio Relay League amateurs in an investigation of short waves during manceuvers of the Pacific Fleet this summer; the other, the announcement of John L. Reinartz's theory of daylight transmission.
WHAT THE AMATEURS ARE DOING
IN ORDER to carry out the navy experiments successfully, F. H. Schnell, traffic manager of the American Radio Relay League who has been given a seven months' leave of absence by the League, will conduct tests with amateurs in many countries. His work will serve as one more important link between American amateurs and transmitting operators in other parts of the world, and he will, at the same time, demonstrate under official supervision what short waves can do. His experience as traffic manager of the A. R. R. L. has given him a wide acquaintance among amateurs which the Navy believed would be of great service in the short wave tests and so it called him in active service in the Department with the rank of lieutenant.
It is significant that following closely upon the first international amateur congress, the
U. S. S. Seattle is now steaming in Pacific waters equipped, among other apparatus, with a typical amateur radio transmitter and receiver. This first amateur type station to be installed on a Navy ship will have the call nrrl. One may imagine the interest and enthusiasm in which amateurs in Australasia, the Philippine Islands, China, Japan, South America, and probably Europe and Africa will listen for this special Navy station, pleased with the thought that the communication they have helped to build has been recognized bv the United States Navv.

SEATTLE
EXPERIMENTS
THE amateurs who intend to listen for nrrl, no matter whether they are located in this or foreign countries, must be prepared to tune-in on a number of different wavelengths, for the tests are to cover several bands of short waves. At night, the main set at nrrl will transmit on 54.4 meters while in daylight it will shift to 27.2 meters. There will also be transmitters functioning on 20, 40. and 80 meters.
If it is found that the low power amateur stations employing less than one kilowatt are just as efficient as regards the distance covered and dependability of operation, it may be seen very readilv that their use would mean
