Abstract
IN World Radio for April 15 there is an interesting account of a motor tour by R. M. Bell in the United States with a portable receiving set. As good highways connect all parts of the country, the 3000-mile trip from the Atlantic seaboard to Los Angeles can be made quite easily. The tour brought within daylight range most of the American stations. In Chicago the 25 local stations made it difficult to hear outside stations. Doubtless the same difficulty arises in New York, which has 43 local stations. Near Chicago, a relay from Poznan came through in excellent volume. There are nine television stations at present ‘on the air’. Chicago uses 45 lines per picture and 15 pictures per second, New York uses 60 lines and 20 pictures per second. In Los Angeles, the 17 local broadcast stations, several of which are ‘on the air’ for 24 hours daily, made reception from other cities practically impossible, but a number of international relays from abroad were heard from them. The B.B.C. orchestra was heard as distinctly as it is in London. When passing through the Japanese and Mexican portion of the city, the street resounded with a speech from Berlin. In Tennessee, near Nashville, Los Angeles, 1775 miles to the west, and New York, 775 miles to the east, could be heard easily on the portable receiver. The writer mentions that Los Angeles (KFI), Dallas (WFAA), and Cincinnati (WLW) transmitted splendidly. In daytime they could be heard at a distance of 300 miles in good volume, and at night at distances of more than 1000 miles. When he got back to Pennsylvania, he heard at 7 A.M. the toasts given at the Lindbergh banquet at Tokyo (9 P.M. in Japan) being relayed from the local networks.
