French experts plan radio tests ten miles aloft

The characteristics of wireless waves ten miles aloft are to be tested by French scientists. Aeronautical experts of the French army have arranged to send up a small balloon which will carry with it a very light radio set that will automatically send out signals. From a like set, signals will be sent at the same time from the ground. The signals from both sources will be carefully recorded and studied. From the experiment it is hoped to obtain information regarding the effect of atmospheric conditions on wireless waves that will aid both aviation and wireless. — Telegraph & Telephone Age.
