Radio Eavesdropping Banned by FCC
Under proposed new rules voted unanimously by the FCC, all types of electronic
snooping that depend on transmitting equipment would be outlawed. This ruling is
due to the increased practice of concealing small units which include a microphone
and radio transmitter in places where they can pick up private conversations, transmitting
the conversations to a receiver possibly as much as a mile away.
The reason for this apparently late action on the part of the FCC is that up
to a short time ago transmitting equipment was bulky and power-consuming. Thus attempts
to use a transmitter in eavesdropping were rare. Now miniature transmitters smaller
than a pack of cigarettes can operate for a month or two on a set of batteries,
sending out all conversations they pick up.
Largest Magnetic Memory Announced by RCA
A computer mass memory with a capacity of 5.4 billion characters has been announced
by RCA. Built up of a large number of magnetic cards 16 inches long by 4 1/2 inches
wide, the memory has a recovery speed of about 1/3 of a second for obtaining any
data from the large bank.
There are 64 magnetic bands on each card, carrying a total of 166,400 characters.
The cards are stacked in magazines of 256 cards and 16 magazines comprise a unit.
Up to 8 units can be used in a single system, giving the fantastic number of 5 1/2
billion characters approximately.
Number One Ham Dead
Irving Vermilya, who held the first, or one of the first, amateur licenses issued
by the United States Government, is dead at Mattapoisett, Mass., at the age of 73.
Although he held amateur license No.1, dating from 1912, the first license examinations
were given simultaneously in a number of places throughout the country, so actually
more than one license was marked No. 1.
Vermilya had been a transmitting amateur before receiving the license and was,
in fact, an active radio amateur enthusiast since 1901, when Marconi gave him a
small receiving set. He served in the Navy during World War I and was one of the
charter members of the American Radio Relay League. His call, 1ZE (later WIZE),
was heard throughout the world.
Space Students Prepare for Out-of-This-World Careers
Nearly 1,100 students in 131 colleges and universities will participate in postgraduate
training in space-related subjects. The program is sponsored by the National Aeronautics
and Space Administration, which supplies grants of $2,400 for each student for 12
months of training. If the student maintains a satisfactory record, he is assured
of 3 years of pre-doctoral studies.
According to NASA Administrator James E. Webb, "The pre-doctoral training program
is making excellent progress toward its major objective - helping to meet the nation's
future needs for highly trained scientists and engineers ... in space-related areas."
What's New
New Type Silicon Power Semiconductor - "Triac" - works like silicon
controlled rectifier but conducts in both directions to permit control of ac
power. Device has high trigger sensitivity, and replaces SCR or diode
back-to-back pairs. Photo shows press-fit and stud-mount versions of the new G-E
device with proposed symbol in background.
FM Wireless Microphone transmits to any 88-108-mc FM receiver up to 200 feet
away. One of the first type-approved under recent FCC ruling. Inset photo shows
midget size-smaller than a pack of cigarettes. Device, made by Kinematix, Iric.,
has three transistors, single mercury cell, built-in microphone.
