1940 Radio and Television
January
- Included Foto-Craft Magazine
Television Query - "I was just at the NY World's Fair ... why
aren't these new televisions advertised?"
Photographing Television Images !!
If you like photography (like I do), then you will find this article
fascinating. At least someone was taking screen pictures in those
first days of broadcast TV ..... If we could only find a stash of them in a New
York attic somewhere!
May - Still Included Foto-Craft Magazine
(But not for long!)
Television Audience Sees City Through Plane's
Eyes! FIRST PUBLIC DEMONSTRATION of
television being broadcast from an airplane equipped with a camera and
miniaturized transmitting equipment !! The test was conducted jointly by
RCA, NBC and United Airlines. The transmitter weighed 65 pounds and
delivered 6 watts output. Onan and Sons, of Minneapolis, Minn., designed
the 110 volt, single phase, 4,000 watt power plant. The cameras used the
'new' iconoscopes, which were 'considerably' more sensitive than the standard
pick-up tubes. The demonstration was "astounding", and pointed
the way to TV-controlled airplanes of the future. Approximately 10,000
people watching a total of 2,000 pre-war television sets in the vicinity of
Schenectady, Albany and Troy (New York) saw this historical telecast. May
1940 -- amazing.
July - (No more Foto-Craft Magazine!)
RCA's new projection tube, which can deliver 4-1/2 x 6 foot pictures, was
demonstrated for RCA stockholders. The actual size on the face of the
kinescope was 2.4 by 3.2 inches, and required 56,000 volts to operate the
tube! The picture was magnified 22.5 times with the aid of a 16"
diameter concave mirror. The image was projected a total of 20 feet, and
observers called the picture 'excellent' !!
Announcement that NBC would be the first to broadcast the National
Republican Convention, beginning on June 24, 1940. NBC estimated a total
audience of 40,000 viewers, based on the belief that 8 to 10 persons would watch
each available pre-war set in the relay extending from Springfield, Mass., to
Philadelphia, New Hope, and other points in Pennsylvania now being served by
NBC's W2XBS New York transmitter. The Philly to NYC relay was to be made
over the new coaxial cable installed by Bell Telephone Labs and the American
Telephone and Telegraph (AT&T) Company. Although the cable was capable
of handling hundreds of simultaneous phone conversations, it would only be able
to handle one single TV program signal!
