opening, Dec. 15, as indicative of what may be expected during 1925. Radio listeners who are opposed to children’s programs and bed time stories should tune' in WOC some evening at 7 p m. and listen to Miss Val McLaughlin, the WOC “sandman” It’s an even money bet that the charming voice of this young lady will win you over and make you a regular listener. WOCs new station, combined with some excellent talent, has been giving the radio fans some wonderful

programs during the past several weeks. —.'.l ECEIVING conditions have W improved greatly during the ■ past week. Distant stations have been coming in with excellent volume and there has been very little from static. Thursday and Saturday evenings were ideal and both evenings were blessed with excellent programs The outstanding event on last week’s programs was the Victor program broadcast by WHAF, WCAE, WGR and several other eastern stations. John McCormack, world renowned tenor, and Madame Borl, famous operatic star, made their radio debut on this program, and, according to the letters, telegrams and cards received by the Victor Company, they were heard in almost every part of the United States and Canada. Similar concerts presenting stars of the opera and concert world, will be given every other Thursday evening. These programs, combined with the Brunswick Hour of Music, which go on the air every Tuesday evening, will provide the radio listener with the best music obtainable. If you enjoy real dance music dial WTAM on 390 meters any Saturday evening and listen to Ev Jones and his WTAM orchestra. It is hard to find a better group of entertainers anywhere on your dials. When a man leaves prison he needs all the aid possible to help him back into society. Radio has proved a valuable- asset in the case of Harry M. Snodgrass, known to thousands of listeners through station WOS. Many gifts have been sent to him and his family on the eve of bis departure from confinement. It is the writer's belief that Snodgrass will prove himself worthy of all that radio fans have done for him.

~ PATENTS 1 Bu Timex Special WASHINGTON, Jan. B.—Three patents on radio Inventions were granted by the United States Patent Office during the past week. A brief description of each of these Inventions follows: RADIO GAME (1.520,082), Invented by Commander Wiliam R. Purnell of the United States Navy. The radio game invented by Commander Purnell is somewhat on the order of tiddle-de-winks. A tour-wire antenna, mounted on small masts, is provided with chips haring hooks on them. The chips are tossed, or snapped, with the object being to hook them on the antenna. Each wire of the antenna has a certain value and a chip hooked on it gives a certain score to the player. VARIABLE CONDENSER (1,520,329), Invented by C. S. Cherpeck of Chicago, 111. One of the main objects of this invention Is the provision of a variable condenser especially adapted for radio work, provided with means whereby the capacity of the same may be varied through quite a wide range, and which variation shall be manually controlled so as to enable the operator to make very delicate adjustments for proper tuning and variation of wrve lengths. CONDENSER .AND HOLDER THEREFOR (1,520,027), Invented by A. Atwater Kent of Ardmore, Pa., and assigned to the Atwater Kent Manufacturing Cofnpnay. This invention provides a condenser unit or structure having terminal strips communicating with the different armatures or plates of the condenser and extending longitudinally of the unit exteriorly there to and then transversely. (Copyright, 1924, by Stevenson Radio Syndicate.) WIRELESS SAVES. LIVES Crew of Ship Saved After Call for Help. \ WASHINGTON, Jan. B.—An instance of where radio saved the lives of the crew of a vessel, has just been reported by the Lighthouse Service. George K. Martin, mate of Pollock Rip Light Vessel No. 110, on the afternoon of Nev. 17 received distress from the schooner Rebecca G. Whelden, which was pounding over the broken part of Pollock Rip. The mate sent out a wireless call for help and this was answered by the steamer A. L. Kent, and the crew was rescued at 5:25 p. m. hy the vessel. The schooner was lost, but it was probably through the alertness and prompt action of the mate that the crew was saved. DX Causes Blow-Up R. B. Bourne, an amateur of West Hartford, Conn., was so excited wuen he heard another “ham” from New Zealand'that he put on all the power-he could to maintain communication and soon found himself sitting on the floor with his entire set a wreckage around him.

END TO SPARK STATIONS URGED Interference Is Given as Reason for Move.' Bu Timet Special WASHINGTON, Jan. B.—Abandonment of spark transmitters by amateur radio stations because of interference to broadcast reception is urged by the Department of Commerce in new regulations governing their operation which have just been issued to all radio supervisors. The new regulations, which specify future wave lengths for amateur stations, also compel them to observe silent periods between 8 and 10:30 p. m. daily and during church services on Sunday whenever they tend to interfere with broadcast reception. New wave lengths to be used by amateurs are 150 to 200 meters, 75 to 85.7 meters, 37.5 to 42.8 meters, 18.7 to 214 meters and 4.69 to 5.35 meters. There being no further need for
