RADIO DIGEST ILLUSTRATED REPORT "YES" ON LAW (Continued from page 1) The agreement reached between Secretary of Commerce Hoover and Secretary Denby and their advisors has altered the bill so that it now carries a clause that army and naval Stations shall not require commercial licenses, that their wave lengths will be assigned by the President, but that when commercial traffic is handled rules and regulations designed to prevent interference with other Radio stations will be observed. In other words, governmental stations when transmitting other than official matter will use commercial wave lengths and comply with all regulations set down by the Secretary of Commerce. One feature of the Bill increases the membership of the advisory committee of the Secretary of Commerce from twelve to fifteen, including a representative of the treasury department, another from the shipping board, and an additional member who is not a governmental official. FLEWELLING CONTEST TWO WEEKS LONGER OWING to insistent demands from interested Flewelling circuit experimenters, the Flewelling prize contest under the auspices of Radio Digest will be open to contestants two weeks longer. This will make the contest close February 10 instead of January 27th. The prize awards will be announced in the March 3 issue instead of the February 24, to make allowance for the extension. The rules of the contest are given on page 2. Auto Gets Stuck; Radio to Rescue Stranded Quartet Uses Home-made Set to Relieve "Sting" of Misfortune i FLEWELLING PRIZE CONTEST RULES BOSTON, MASS. — A letter has been re ceived by Station WNAC, the Shepard Stores here, from a member of the Salisbury, N. C, Lodge No. 699 of Elks, telling how he heard the concert given by Boston Lodge of Elks on January 3, while on a trip from Salisbury to Lynchburg with his wife and another fellow Elk and wife. The party got stuck in the mud about eleven o'clock at night, ran into a ditch and broke an axle (they have some awful roads in some parts of the south), and five miles from the nearest town. The Salisbury Elk had a homemade Radio set in the car, so he decided to try for some music to while away the hours until daylight, when they could be able to foot their way to town for help. Erect Temporary Aerial They ran a one-wire, 25-feet aerial from a tree to a rail from a fence which they stuck in the mud in front of the car, working all the while in the rain. The highest part was not over eight feet from the ground. Tuning in slowly, they picked up WNAC, just then broadcasting the Elk's entertainment. "Never did I hear music that sounded so good, far out in the rain and lonely country," continues the writer. "We heard you acknowledge messages from Haverhill, Newburyport, Woburn and many other places. It gave me an idea to send a long distance phone call to Bost'on. "We walked for almost a mile to the nearest house where they had a rural telephone. The exchange operator tried for about an hour and although she got through to Boston, could not get the Shepard Stores, so I imagine you had all gone home." 1.

S. Scott, of this city, borrowed some current from WHK, the local broadcasting station of the Radiovox Company and sent a message that was received at Independence, Kansas, and Butte, Montana. Station WHK's wave length is 360 meters. Mr. Scott's set is located at his place of residence, about six hundred feet distant from the Radiovox station which had finished broadcasting, but had not shut off their generator and was still putting out a carrier wave. Mr. Scott tuned his receiving set to the station wave length and by tapping with his finger on the grid terminal of the tube, gave his official, amateur station call, 8BFL, asking to be notified of its reception. In due time, postal cards were received from amateur stations at Independence, Kansas, and Butte, Montana, stating signals were received QSA (loud). Mr. Scott was formerly a Radio operator with the Marconi company, and is now in the engineering department of the Ohio Bell Telephone company, at Cleveland. Mr. Scott is in charge of the Radio Engineering class at the Cleveland T. M. C. A., and is very active in Radio work in this city. Looking Ahead Final Appeal Brings Funds to Finish Construction Bills LONDON, Ont., Can. — Radio played its part in the opening here recently of the beautiful new Western Ontario War Memorial hospital for sick children. It was the ambition of the directors of the new institution to have it entirely free from liabilities by its opening date, but a few days before the scheduled opening it was discoveried that there were still several accounts outstanding which aggregated some few thousands of dollars. A day was selected when there were to be a number of large public meetings at various smaller Western Ontario centers and arrangements were made with a local broadcasting station and with amateur operators in the towns where the mass meetings were to be held, to broadcast a final appeal for funds. The next morning's mail brought all the additional funds that were required and quite a cash surplus. This was set aside in order to equip a Radio auditorium where the little patients may listen to concerts broadcast from local, Detroit and Toronto stations. POOKS E. T. Flewelling, Himself, will begin a series of exclusive articles on the circuit bearing his name in the next issue of the Digest. If you are having trouble with your Flewelling "flivver," read what the inventor has to say. It will be sure to help you. Remember Flewelling is writing exclusively for Radio Digest. Reinartz Questions and Answers will fill page 15 in the next, the February 3, issue. If you want a simple, sensitive and efficient regenerative set, build a Reinartz tuner from Radio Digest's articles on the subject. If you have one but can't get results, read the "Q. and A." page next week. For the Picture Fans. Ever heard Miss Jessie Koewing of WOR, the first woman announcer in the United States? Or the announcer on the other end of WJAX, Cleveland? They have furnished the Digest with pictures and satisfactory accounts of themselves and will appear on page five next week. Buy the February 3 issue and you can visualize two more mysterious announcers' voices. How to Construct and Operate a Crystal Detector Receiving Set will be told next issue by Arthur G. Mohaupt in the fifth chapter of his "A-B-C Lessons for Radio Beginners." Many fans stick to the crystal. Every crystal user or beginner should read Mr. Mohaupt's article. Lets on Balliet Was Unfortunately the Victim of a Train Wreck, and hence his long-promised series of beginners' articles has been delayed. But Mr. Balliet will leave the hospital soon. Just when he will be able to resume his work of writing the series is indefinite, but "looking ahead." Part II of the Radiophone Broadcasting Station Directory will appear in the February 3 or next issue. You would be surprised at the expense and work necessary to keep this feature up-to-the-minute for Radiophan readers of Radio Digest.

Here's Something New in Revivals WNAC Broadcasts Noonday and Sunday Sermons of Rev. Massee, Evangelist By F. XT. Eollingsworth BOSTON, MASS. — Up-to-date revival services are those being conducted at Tre-. mont Temple by Rev. Dr. J. C. Massee, a noted evangelist, whose sermons every noonday as well as Sunday mornings are being broadcast from the Shepard Stores Station WNAC, via a telephone-microphone connection between Tremont Temple and the broadcasting studio. Dr. Massee says that he has been informed by one of the Radio listeners, a prominent and wealthy business man whose name he refused to give, that the latter had been converted by Dr. Massee's preaching after listening in to it over a Radiophone. Contributions Mailed In Numerous letters have also come in from people who stay at home and listen in by Radio to the revival services, and many of them have contrained contributions. One letter was particularly appealing. It was from a crippled boy, who informed Dr. Massee that every day during the serivces he has been carried to the home of a neighbor to listen in over the Radiophone. He sent two dollars in his letter, a dollar of it to be devoted, he asked, toward helping some other crippled boy or girl to hear the services by Radio through the kindness of some neighbor who had a set. To Broadcast "Brimstone Corner" Arrangements have been made by Station WNAC to broadcast the services from Park Street Church, Boston. This is one of the most famous churches in Boston, located on the corner of Park and Tremont streets. The corner, from the character of the fiery sermons preached in years past, was long known as "Brimstone Corner." On the first and third Sundays in the month, services from Tremont Ternpie will be broadcast. With the broadcasting of the services from St. Paul's Cathedral every Sunday morning and Dr. Massee' s service at noonday, New England Radiophans and all within reach of WNAC are fortunate. Owing to the severe weather of the past few weeks, many have been prevented from attending church, but have had the services brought to their homes by Radio. Alabama Farmers Wake Up to Value of Broadcasts BIRMINGHAM, ALA. — The farmers of Alabama have commenced to make use of Radio. Throughout the state many farmers are availing themselves of the crop summaries and market reports now being broadcast by Station WST. Recently Roy C. Bishop, secretary of the Alabama Farm Bureau Federation, took advantage of an invitation of the Alabama Power Company's plant in pushing the membership drive of his association. This organization now numbers 7,000 in Alabama, and Mr. Bishop stated that by the use of Radio he expected to more than double the membership within a few weeks.
