Radio waves high flyers, Washington, D.C., Oct. 1. Experiments conducted by H.W. Wellex at the radio station of the Carnegie Institution have proven that radio waves travel a distance of 80 miles heavenword before they are reflected back to earth. Traveling like lightning as they ascend in to the ionosphere the radio impulses have to be measured in 10,000ths of second to accurately check the height reached before they return to the radio set
