Radiophone Communications Record
On 3 June 1929 the first two-way, radiophone communication took place over the skies of the Packard Proving Grounds in Utica, (now Shelby Township, Michigan). Heretofore, gasoline powered aircraft caused too much electromagnetic interference for the weak voice signal to be heard over the static. Only a strong Morse code signal could be heard. As diesel engines neither have spark plugs, nor spark plug wiring the EM static was greatly reduced and allowed voice communication to be used. The two-way ground to plane voice communication was witnessed by the U.S. Department of Commerce.Applications
