1) Two (2) Passive Intercept Receiving Systems including Filters and Cali-
brator will be completed. The third system will not be completed.
2) Complete Spare Parts for two (2) systems is required. A quotation is to
be prepared to estimate additional funds required.
3) A revised quotation is to be prepared to estimate the cost of the design
of, construction of, and spare parts for Modification Kits for the inclu-
sion of CW reception capabilities for two (2) Systems. The revision is
necessary since additional design work will be required to achieve the
-35dbm minimum sensitivity desired.
4) Sales is to initiate a quotation number for a Study Program to improve
CW Detection in Crustal Video Receivers. This .aork is to be done at X
band with a goal of -45dbm minimum sensitivity. A breadboard model or
Sd6~ccr models and an engineering report will be deliverable. The study phase is
e ,e iar of to include :
Necsf br5P0 a) Improved Detector Mounts and Crystal Detectors
b) Improved Transistor Circuitry for CW Detection
c) RF Modulation and other new methods.
A second phase may include prototype models dependent upon the results of
with contract numbers of
the study phase.

5) The quotation for 250 Amplifier Units is to be revised as follows:
a) A firm quotation is to be submitted for Phase I of this program to
include ten (10) developmental units, environmental tests and an en-
gineering report. The system is to include
minimum sensitivity.
b) A budgetary estimate is to be submitted on Phase II which is to include
the production of a minimum of 170 to a maximum of 200 Amplifier Units.

6) The status of System No. 1 was reviewed with a trip to a where Systems
Tests are underway. The components, namely, helical antennas, filters
for Bands 5 and 6 and the modified "Grace Mount" crystal detector are to
be= catalog items, therefore, only control drawings will be submitted.
7) Future developement of the system was discussed. With the use of the
newly developed spiral antennas it was felt that an appreciable size re-

to determine the possible

use of this type of antenna and the company's interest in producing an-
tennas specifically for this system. The possibility of combining the pre-
sent Bands 1 and 2 and obtaining good performance as low as 50 megacycles
seems likely with the spiral model. This and developement of suitable an-
tennas above 40 KMc is of interest to the customer.
