Address all Communications: P.O. Box 437, DUNEDIN.

" Chatterbugs " Operators licensed by the American authorities have been warned that there must be no unnecessary chatter during communications. Failure to observe this rule earned a censure for a Pacific Coast ship captain. The skipper was in radio contact with another vessel about position and weather-and could not refrain from cursing the latter. His unlawful superfluous language was overheard. New Television Station The American radio industry has the opportunity, while British television is at a halt, to develop the "see and hear" sphere. The Federal Communications Commission has ruled that at this stage there must be no "frozen" standards in the industry and two new stations which will experiment on different lines have been licensed for Ohio and New York. A transmitting system in which the picture is composed of 30 frames per second, interlaced, will be used by the Ohio station. Tests will be conducted with 441 and 507 lines, as well as an intermediate number of lines. The New York broadcaster will transmit a picture of 15 to 30 frames, using 441 to 729 lines. Both stations will use 1 kw. aural and visual power and will cost approximately $100,000 each. Moscow is Loudest RV96 Moscow on 9.52 me. is the loudest station on the 31 metre band at the present time. On Sundays it is on the air between 4 and 5 p.m. with news in Russian and recorded music. Recordings of a children’s choir heard recently were particularly good. " Static-Less " Educational Broadcasts The first use of FM (frequency modulation) broadcast in the non-commercial educational field is proposed by the Board of Education of the San Francisco Unified School District as a result of its being granted a construction permit for a new station to operate on 42,100 kilocycles with 1 kilowatt power. The board intends to use radio for instructional, administrative, supervisory, and other functions in the local schools. Thirteen studios are planned for high schools and colleges in that area. They will be connected with the broadcast station by means of leased wires. In this manner it is expected that a greater number of teachers and pupils will be enabled to participate with less effort and expense of transportation. The broadcast programmes will cover nearly all of San Francisco as well as the East Bay area which includes the cities of Alameda, Oakland, Berkeley, El Cerrito and Richmond. The Board of Education, which is the governing body of the San Francisco Unified School District, has allocated $9,000 for the station, and an additional amount of $42,000 has been made available. Three other institutions were previously licensed to use AM (amplitude modulation) on the channels set aside for non-commercial educational purposes. They are the New York City Board of Education, the Cleveland Board of Education, and, more recently, the University of Kentucky.
