Broadcasting (Oct 1931-Dec 1932)

WHEN YOU MEASURE COVERAGE ♦ ♦ ♦ don't forget percentage modulation m Field-intensity data are basic in determining coverage, but they aren't the whole story by any means. Percentage modulation is just as important a factor in pumping more power through your listeners' loud-speakers. m Consider that an increase in percentage modulation from 50% to 100% will increase the loudspeaker power by four times. Yet the field intensity of the carrier remains the same. That is why the Federal Radio Commission demands that you modulate at high percentage. ■ But remember that unless you exercise extreme care your high-percentage modulation will be accompanied by serious distortion. Even in properly designed transmitters a wrong value of grid bias, for example, may cause trouble. ■ You can check on the performance of your transmitter at high-percentage modulation by means of a General Radio modulation meter. It not only measures accurately your percentage modulation, but it shows up distortion due to asymmetrical modulation of the carrier. The General Radio modulation meter is coupled to the transmitter-output circuit, its operation is in no way influenced by transmitter changes. Let us tell you more about the General Radio modulation meter. Write us for literature.

The court soon is expected to render its decision on the appeals of WIBO and WPCC, Chicago, from the Radio Commission's decision ordering their deletion, which raises the question of property rights and the legality of the Commission's quota system. Also ready for decision is the appeal of KGEF, Los Angeles, deleted by the Commission because of the broadcasts of Rev. Robert P. Shuler, which raises the question of free speech on the air. The court on Sept. 16 granted the petitions of KOIL, Council Bluffs-Omaha, and of WAAW and WOW, Omaha for a stay order restraining the Commission from making effective its decision authorizing KICK to remove from Red Oak to Carter Lake, la., a suburb of Omaha. All three stations, through counsel Paul M. Segal and George S. Smith, appealed from the decision, rendered Sept. 13, on the ground that they would be adversely affected and that it violated the law and Commission regulations. Numerous other routine actions on pending cases have been taken by the court. Oral arguments on the appeals of WNJ, Newark, N. J., and WMBA, Newport, R. I., both of which were ordered deleted by the Commission, have been set for Oct. 3. Both stations also were granted extensions for filing briefs. In the high power case, involving appeals of WGN and WMAQ, WLW Adds Noted Stars To Its Dramatic Staff FOR ITS WINTER radio drama series, WLW, Cincinnati, has added four noted stage and radio stars to its staff following a series of auditions conducted in New York by Richard Nicholls, program director. At the same time, WLW announced the addition to its staff of Jeff Sparks, who comes from the New York studios of NBC, where he announced such programs as "Death Valley Days" and the A. & P. "Our Daily Food" periods. The new dramatic staff additions are Anne Seymour, well known on Broadway; Gladys Thornton, who has been heard on NBC and CBS and with the Theater Guild and Dramatic League; Clifford CarsonJones, who will play leading roles and who has been heard on the radio as well as with Broadway companies, and Maurice Franklin, who has played leading roles in the "True Story Hour," "Rise of the Goldbergs" and other features. WLW also announced that Gene and Glenn have been signed for a daily series over WLW and WTAM, sponsored by Standard Oil Co. of Ohio. Chicago, WJZ, New York, and KGO, Oakland, Cal., from the 50 kw. grants under General Order 42, as amended, the court granted all applicants until Oct. 11 to file briefs. The Commission was granted a 30-day extension to Oct. 29 for filing its brief in the appeal of WOQ, Kansas City, from the order deleting it. WLOE, Boston, was granted until Nov. 15 for filing its brief. d.'.7 Aiis> A>jtyJii*sl>j CAMBRIDGE A, MASSACHUSETTS We say "Yes Ma'am" to our Cooks Women cooks prepare the food for the Hotel Lexington restaurants. That's why it's so delicious and wholesome. And Lexington restaurant prices, like its room rates, are sensible — 35c for breakfast, 65c for luncheon and $1.00 for dinner in the main dining room. $3 a day and up for Lexington rooms — $4 and up for two persons.
