the modification of DAQ's was discussed.
for
(a) t yet supplied the basic DAQ equipments.
(b) have not yet received a definitive contract.
(c) e has been constructed.
(d) are in the process of designing the antenna
matching rens ormers. Several experimental models were shown.
Design and tests are not yet complete. They are not sure yet whether
it will be necessary to use two types of transformers to cover the
frequency range.
(e) Operating frequency range of the Navy Equipment will be
1.5 to 22 mcs.
(f) They hone to be able to use the DAQ goniometer as it stands.
(g) stated that delivery of the first complete system
to the Navy is anticipated in December 1951, followed by the delivery
of the second com Late system in January of 1952.
(h later made the statement that they hope. to have 50X1
one camp e e an enna array erected for the first time for tests in
about one month. (This conflicts with item (g) above).
(i) They are having difficulty procuring the aluminum for the
antennas.

3. The Agency's requirements were outlined as follows:
(a) Modification of DAQ's similar to the Navy Contract.
(b) Produce three complete systems as mentioned in (a) except
use a single DAQ for each pair of antenna arrays and provide circuitry
for bwitching to either the High Frequency Array or the Low Frequency
Array.

(c) The equipment must be transportable.
4. agreed to submit a technical proposal by mail in
the next few days which will define their approach to the problem and
state when delivery can be made and the total cost of the modification.
However, this was his verbal response at the time:
(a) The Agency will be required to procure the aluminum
for the antennas. A detailed list of material required is
addended to this memo.
(b) The Agency will be required to supply approximately
8000 feet of RG/24-U double coaxial cable.
(c) From the date of delivery of these above materials and
the three DAQ's, the first complete system could be delivered
in 60 days, the second and third systems could be delivered at
the end of 90 days.
(d) It will probably be necessary for the Agency to deliver
three extra goniometers of the type used in the DAQ.
(e) An undetermined number of co-axial switches will be
necessary.
S. It is the writer's opinion that their estimate on delivery may be
somewhat optimistic. The opinion is based on their apparent progress on
the Navy Contract and a survey of their Engineering facilities.
6. If the aluminum for the antennas is not available, stainless
steel might be substituted with a resulting increase in weight and cost.
