Task Order #3
AUTH: MR 104
JUST NEXT REV
Since the receipt of a fully executed copy of the referenced Task
Order in early Mety 1956, work has been progressi on the VEF Ferrite
Antenna project. In our proposal for this work
dated January 1956) Phase A was indicated to be of approximately four
(4) months duration. During the past week, a telephone call was received
from your office, inquiring into how we were progressing toward our
delivery schedule, and requesting that information on sensitivity, gain,
patterns, spurious response, and selectivity curves be included in our
study and report.
We feel it is desirable to indicate here, the schedules we are
working under and the scope of work we intend to pursue. The original
specifications on this work were very loose, essentially calling for
twenty (20) narrow band units, tunable over a calibrated spectrum of
50 to. 200 megacycles with a selectivity of approximately five (5)
megacycles. Since cadencing work, considerably more information than
was originally to be furnished has been verbally requested. While this
is desirable information, it is considerably beyond the scope of the
originally proposed work of Phase A. Also at the request of your office,
we have changed the dimensions of the carrying case, after completing
same, from 2" x 2" x 6" to 1 3/8" x 2 1/2e x 6". There was no specifi-
cation on the tuning mechanism, and we originally proposed the use of
a helipot dial which was entirely adequate for calibration purposes.
Your office now feels, however, that it does not produce the most desirable
package. We, therefore, constructed three variations of tuning
mechanisms and demonstrated these to your Project Engineer. Thus,
instead of getting a reaction on a more desirable configuration after
the delivery of the twenty (20) units, we have been making periodic
changes in accordance VMh your office's requests.

1. One tunable narrow band unit in 1 3/8" x 2 1/2" x 6" package
with micrometer tuner available for demonstration with frequency
calibration, but no other data on September 12, 1956. (A 2"
x 2" x 6" model with micrometer tuning is available at the
present time.)
2. Ten units in 1 3/8" x 2 1/2" x 6" package with micrometer
tuning with frequency calibration available for delivery on
October 8, 1956.
Nine tunable narrow band units in the 1 3/8" x 2 1/2" x 6"
package with micrometer tuning and frequency calibration available
for delivery on October 26, 1956.
August 31, 1956
In consideration of the above factors, we expect to accomplish the
following schedule for delivering the twenty'(20) narrow band and ten (10)
wide band units called for under Phase A:
4. One tunable narrow band unit in the 1 3/8" x 2 1/2" x 6"
package with micrometer tuning with frequency calibration,
sensitivity curve, selectivity curves, antenna gain curve,
and antenna patterns will be available by approximately December
1, 1956. Some of these measurements are dependent upon obtaining
the use of more adequate VHF antenna measuring facilities than
are available at our plant at the present time. Negotiations
are underway to obtain the use of a radio darkroom. The sensi-
tivity, selectivity, gain, and patterns will not be measured on
a continuous basis, but rather at selected frequencies in the
band 50 to 200 megacycles. If feasible, some measurements will
be made on spurious responses in the band 1 megacycle to 1000
megacycles, although it is not visualized as being within the
scope of Phase A (or Phase B) to make measurements of the
spurious response over the band 1 megacycle to 1000 megacycles.
5. Ten wide band units 1" x 1 1/2" x 6" available on October 26,
1956.
Although some of the additional information and changes, requested
verbally by your office at this time, was intended to be included in
Phase B, many of these changes are not within the scope of work we
proposed to undertake in either Phases A or B. For this reason, there is
some likelihood that additional costs above and beyond those provided
by the referenced Task Order will have to be made.
It is suggested that at the next progress review meeting we discuss
the consequences of this additional work on program schedules and costs.
