('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 />
