('LIGHT of utilities radio continues to worsen. Requests<br />

continue to pour in for additional frequency<br />

.allocations. Co- channel arrangements have been the<br />

only answer to requests in the 30 -50 MC and 152 -160<br />

bands. Consideration is now being given to a Split<br />

Channel proposal, but the FCC has warned that even<br />

if a solution is found to problems of engineering,<br />

frequency coordination and operation there is no<br />

assurance that the new channels made available by<br />

Split Channel operation will be allocated to the service<br />

to which the original channel was allocated.<br />

ENGINEERING SHORTAGE can be minimized, says<br />

Brig. General David Sarnoff, by instituting a three<br />

point program: 1. That atomic reactors be constructed<br />

on selected college campuses. 2. That the<br />

nation's youth be polled to determine why so few<br />

take up scientific careers. 3. That industry and Gov -<br />

ernment eooperate in establishing a "National Educational<br />

Reserve" made up of teachers drawn from<br />

industry.<br />

COLOR <strong>TELE</strong>VISION<br />

THIS MONTH will be crucial for color TV. With<br />

the programming problem solved, at least to a large<br />

extent, by WNBQ's all -color operation in Chicago<br />

the one remaining obstacle -receiver price -gets industry<br />

attention. RCA is expected to announce a<br />

sharp reduction, possibly to $495.00, but a better<br />

guess would be $595.00. The marketing technique<br />

that was so successful in introducing B & W -first<br />

getting the sets into local taverns and other public<br />

places -will be pushed in the next few months for<br />

color.<br />

At the same time GE announces that they will be<br />

marketing a color TV receiver in the last half of<br />

this year. Though technical details are being withheld<br />

it is certain the receiver will use a 3 -gun aperture<br />

mask tube with a chassis designed by GE.<br />

MILITARY CONTRACTS<br />

ALL MANUFACTURERS qualified to engage in defense<br />

production are being urged to get their names<br />

in the Register of Plan Mobilization Producers,<br />

-which is compiled by the Government as part of<br />

-their emergency industrial mobilization plans. Firms<br />

.are listed in the register by the military offices having<br />

mobilization planning responsibility for the<br />

items which these firms could produce in an emergency.<br />

Full details are contained in two booklets<br />

entitled, "Purchased Items and Purchasing Locations<br />

of the Department of Defense," and, "How to<br />

Sell to the Department of Defense," both available<br />

from the Central Military Procurement Information<br />

Office, The Pentagon, Washington, D. C. The Government<br />

is most anxious that all firms bring to their<br />

attention their ability to produce certain products.<br />

MATERIALS<br />

ULTRA -THIN copper strip in thicknesses of .00025<br />

in. will permit the design of greatly miniatureized<br />

transformers and other electronic components by<br />

the substitution of tape -wound wafer -type coils for<br />

the coils formerly made from magnet wire. The<br />

Air Force under -wrote the development of the new<br />

process. Small dimensions of the new copper strip<br />

is illustrated by the fact that 1 lb. of material will<br />

make 1,000 r -f television receiver coils. Use of wafer -<br />

coil also facilitates automatic production of components.<br />

JET TRACKER<br />

New electronic equivalent of the manually operated plotting board<br />

was designed by American Mach. b Fdry. Co. to handle high speed<br />

aircraft. Basically a PPI for trace -while -scan surveillance radar,<br />

unit shows aircraft as a coded symbol, and includes a velocity vector,<br />

a 3 -digit identifying number and added pertinent data.<br />
