Section 23 of bill S. 6 as at present written opens the way for a station with inferior equipment to force a division of time with Government stations carrying on essential communication. This division of time on adjoining frequencies in the radio spectrum results in the sacrificing of the radio spectrum in the interests of poor equipment. Interference between radio stations in close proximity to each other either geographical or in the radio spectrum is properly a subject of regulation, and it is believed that authority should be given the commission to regulate such matters. This authority is given the commission in section 4 of the bill, and it is therefore recommended that section 23 be omitted. The Army is by existing law primarily responsible for communication with and within the Territory of Alaska and employs both radio and cable in its Alaskan communication system. The act establishing the Bureau of Aeronautics in the Department of Commerce authorizes the Department of Commerce to carry on certain radio communication in aid of airways. Airways are not being organized in Alaska and will doubtless be serviced by either the Army or the Department of Commerce. In view of these facts it is recommended that the following changes be made in section 28 of the bill so as to cover all governmental agencies authorized to carry on commercial communication: Page 34, line 3, and page 35, lines 7 and 8, strike out "Secretary of the Navy" and insert the word "President." Page 34, line 5, strike out the word "him" and insert the words. "head of the department or independent establishment having jurisdiction thereof." Page 34, lines 9 and 10, strike out the words "and under the control of the Navy Department." Page 34, line 16, strike out "ship and shore" and substitute the words "mobile stations" and "land stations". I submit to the committee a copy of the bill corrected to incorporate and make effective these recommendations. Senator DILL (presiding). The chairman stepped out for a moment and asked me to preside. Are there any other questions? Was there anything else you wanted to say to the committee, General? Major General GIBBS. I think not, sir. Senator DILL. General, have you a copy of that map you could leave so we could put it in the record? You can send down another if you want to. Major General GIBBS. I have here a map of our radio net covering the whole of the United States, and then you have that map of the Alaska system. You can have them both if you like. Senator DILL. I think we ought to have them in. Major COLES. We have some photographs of that Alaska map. Senator DILL. That would be fine, if you would furnish that. Major General GIBBS. And the figures of the business handled over these nets all appear in the annual report and in the House hearings of the Appropriations Committee. Senator DILL. You were going to furnish certain data for Senator Howell, also. Major General GIBBS. Yes, sir. (The Alaska map and the map of the radio net covering the United States, as well as the data requested by Senator Howell, are here printed in the record.) Cost data on operation of the Alaskan system with and without the services of the cable ship "Dellwood," and an estimate of the cost before and after the installation of radio to replace the existing cable. (a) Present cost of operation of complete system, including the cable (b) Cost of operation of entire system, exclusive of the cable ship (e) Cost of operation of complete system with all cable stations (9) Number of words transmitted per year over the present experimental radio circuits between Seattle, Ketchikan, and Seward.. $611, 552. 71 456, 777. 32 228, 388. 66 240, 388. 66 468, 777. 32 9, 968, 118 7, 696 Senator DILL (presiding). Will you come forward, Commander Craven? STATEMENT OF TUNIS A. M. CRAVEN, LIEUTENANT COMMANDER, UNITED STATES NAVY Senator DILL. Will you give your name and connection with the Navy, Commander Craven? Lieutenant Commander CRAVEN. Yes, sir. My name is Lieut. Commander Tunis A. M. Craven, United States Navy. At the present time I am attached to the Bureau of Engineering, in charge of the radio research and design section of that bureau, of the Navy Department. Senator DILL. What was your connection with the Radio Commission, and for how long? Lieutenant Commander CRAVEN. For about six months, from September, 1928, until March, 1929, I was technical adviser to the Federal Radio Commission on all matters, outside of broadcasting. Senator DILL. You say on all matters outside of broadcasting? Lieutenant Commander CRAVEN. Outside of broadcasting; yes, sir. I have here, sir, a brief sketch that the Federal Radio Commission had prepared of my previous service. I thought if you wanted that you could have that in the record. Senator DILL. You may insert that in the record, yes, without objection. (Sketch of Lieut. Commander Tunis A. M. Craven, United States Navy, prepared by the Federal Radio Commission, is here printed in the record, as follows:) BRIEF SKETCH OF LIEUT. COMMANDER TUNIS A. M.

Fellow of Institute of Radio Engineers. Senator DILL. Have you a statement prepared, Commander? Lieutenant Commander CRAVEN. Yesterday I was told, I think about 3 o'clock, that it was desired that I appear before the committee here to give an historical background of radio from an engineering point of view. I dictated certain phases. I do not know whether they are applicable or not. But some of these phases in here may be of interest. In 1912, radio in this country was applied principally to communications between ship and shore. There were a few highpowered transoceanic radio stations used for communication between this country and Europe and between the United States and its possessions. There were a few stations utilized for communications between points within the continental limits of the United States, principally on the Great Lakes and on the Atlantic and Pacific seaboards. The type of equipment used was the so-called spark apparatus and, in some cases, the arc type of transmitter was employed. The cost of the apparatus for transoceanic communication was very great; the cost of radio stations to communicate between points in the United States with any degree of reliability, while not as great as that for transoceanic communications, was too great to create large demand for the use of channels by business interests.
