Soldiers at Army Service School in Colorado Springs, Colorado receive instruction in Radiotelegraphy. The instructions include teaching the Continental code using headphones and high frequency navy test buzzers. Students are seen at the table in the background, practicing special code work, formulating messages, and familiarizing themselves with traffic rules and calls. In the left corner, a group of men are conducting tests to identify faults. This image was taken by a photographer from Colorado College on September 3, 1918.
