Fourth Chicago Radio Show, Nov. 17-22 ( Continued from page 73) The fourth annual Chicago Radio Show is the official show of the Radio Manufacturers' Association, and it is expected dealers and jobbers from as far west as the Pacific coast will be on hand to make the acquaintance of the big men of the industry who will be present at this, the biggest radio show and gathering of manufacturers, dealers and jobbers ever held in the middle west. New York's 1926 Radio Show In Bigger Quarters The radio industry next year will have its annual New York show in the finest exposition palace in America, according to Maj. Herbert H. Frost, president of the Radio Manufacturers' Association. A lease has just been signed on the new Madison Square Garden and Exposition Hall, now nearing completion as the successor to the famous old Madison Square Garden. The radio show will occupy the entire two floors of the new structure. The larger exhibits will be displayed in the Grand Arena, 285 feet long and 110 feet wide. This floor is larger than the old Garden. The Exposition Hall, 376 feet long and 200 feet wide, built expressly for the housing of the largest trade shows, will also be used. This will make in all a total of about 102,000 square feet of exhibition space. The rental is the highest ever paid by a trade show. This tremendous space will be necessary because all the leading manufacturers are centering on this show, the industry being opposed to the holding or more than one show in each city each year. Heretofore there have been two shows annually in New York. Amateurs Help Minneapolis, Minn. — The Twin Cities Radio Club, a joint organization of transmitting radio amateurs of this city and St. Paul, served in a helpful capacity during the recent Twin Cities Radio Show, when, during the course of the show they handled over 700 messages from patrons of the show. These messages were started on their way to all parts of the United States via the medium of American Radio Relay League member stations. The Twin Cities club is allied with the League.
