News Briefs
Uhf on All TV's Now Law
President Kennedy has signed into law a bill that requires all manufacturers
of television receivers to equip their sets with a uhf tuner. This will mean that
all TV sets will be capable of receiving the uhf channels 14 through 82 as well
as the vhf 2 through 13.
The bill gives the FCC authority to require that all sets sold across state lines
be equipped for both vhf and uhf, and to set minimum performance specs for the uhf
tuners. The commission says it will allow a reasonable transition period to give
manufacturers time to get the necessary changes incorporated into their forthcoming
sets.
H-Bomb Communications Interruption Slight
Despite a lot of talk to the contrary, the miles-high megaton H-bomb blast by
the US in the skies over the Pacific blotted out radio reception for only a period
of minutes. Scientists feared a long disruption caused by the explosion temporarily
destroying the reflecting layer in the ionosphere that makes long distance communications
over the miles of the Pacific possible.
TV Repairman Collects For Unusual Job Hazard
Television repairman T. R. McDonald, of Sacramento, Calif., was awarded $75 by
the court for chicken pox picked up on the job. Repairman McDonald had sued a Sacramento
customer who refused to pay him a bill of $165 which he claimed for medical expenses
and lost time after he caught chicken pox from the 4-year-old daughter of the customer.
Satellite Broadcasts Not for the Home
Space-satellite television broadcasts direct to the homes of peoples of the world,
are not practical at this time, FCC Commissioner Craven told University of Washington's
School of Communications.
"There are many problems to be solved," said Commissioner Craven, "before such
a space-satellite broadcast system can be established on a permanent basis." Among
the things the commissioner mentioned were the problems of language, time differences,
technical difficulties in lifting and maintaining the high-powered transmitters
required, economics, spectrum allocation standards and, most important, cost. He
also pointed out that important events which people all over the world would wish
to see do not occur too often. Space flights occur only occasionally, the Olympic
Games once every 4 years, and British coronations even less frequently than that.
Russians Plan Sputnik TV Relay
On the heels of an actual operating Telstar satellite launched successfully by
the US, word comes from the Soviet Union of its intention to launch TV relay satellites
of its own in the near future. The Russians say the Sputniks will be used instead
of coaxial cable to link Moscow TV broadcasts with other parts of the country.
Brief Briefs
Patent No. 3,033,714 has been issued to the Sony Corp. for a
semiconductor device called the "Esaki diode," or tunnel diode.
Transistorized ignition will be optional on Ford Motor Co.'s
trucks in 1963, if present plans are carried out. The new system is expected to
increase spark plug life from 10,000 to 50,000 miles and point life to 100,000 miles.
