2004-133 TINY TOT RADIATION INVESTIGATION
Project Engineer:
All of the tests have been completed-on this project. The report is
in process of being published.
2004-135 PROJECT TAILOR
Project Engineer:
AZrototype plug-in version of the 0.5 and 5.0 watt A-1 emission system
was tested. Tests indicated that the RF power output was not satis-
factory and the units were returned to the manufacturer.
2004-141 JOHNSON THUNDERBOLT LINEAR AMPLIFIER
Project Engineer:
This amplifier was tested to determine its suitability for FSK (teletype)
operation. Tests indicated that the unit was not rated. for continuous
duty and. would overheat if used continually. Emergency operation for
2 or 3 hours can be tolerated.
2004-142 ALERT RECEIVER.
Project Engineer
Tests have indicated that the sensitivity of this receiver is not as
good. as the manufacturer stated. It is, however, useable for the
purpose it was intended.. The report is in process of being published..
2007-1 RADIOLOGICAL SURVEY AND RADIATION DETECTION EQUIPMENT
Project Engineer:
The units stored at were tested for operational ability.
Three units were found inoperative and. they were repaired. A quarter-
ly report was prepared and forwarded to the Chief of Medical Staff.
Batteries and repair components were ordered in preparation for cali-
brating all units.
2007-20 KEYER FABRICATION AND RT-6 TRANSMITTER MODIFICATION 25X1A9a
Project Engineer:
The modification kit developed under this project is being assembled.
by an external contractor. Instructions for field installation have
been prepared.. Radiation tests were performed on the German manufactured.
Distler motor and. the U. S. manufactured. Reflectone PM-1 motor. Re-
sults of these tests showed that the radiation from the Distler motor
was consistently higher than the Reflectone. It was concluded, however,
that radiation from both motors produced noise of a nuisance value only.

Six kits have been completed and forwarded to SEB. Two kits completed
and. will be held by laboratory.
2007-33 EVEREADY ENERGIZER AND GULTON BATTERIES
Project Engineer:
0
The report on the Eveready Energizer batteries was forwarded this
month. The Gulton NiCad Battery report is held pending receipt of
photographs to complete the report.
2007-39 KX-3 (AS-4A TRANSMITDATA TERMINAL) RADIATION MEASUREMENTS
Project Engineer: 25X1A9a
Work will be resumed. sometime during the next reporting period.
2007-40 TRIX TAPE RECORDER EVALUATION
Project Engineer: 25X1A9a
Tests indicate that this device is useable if high distortion, wow and
flutter can be tolerated. The report is in process of being published.
2007-43 RF ATTENUATION 1v1EASUREMENTS ON PLASTIC AND CLOTH
Project Engineer:
Attenuation measurements of a specified piece of plastic (provided, by
SPS) varied from 0.1 db at 4 kmc to l_dbat 20 kmc'in the dry condition.
Attenuation varied from 0.4- db at 4 kmc to 1.2 db at 20 kmc in the wet
condition. Tests on the metallic cloth are being conducted.
2037 AGENT HIGH-SPEED COMMUNICATIONS SYSTEM, RS-16A 25X1A9a

A two-week training course was given on the theory of operation, care

URT 11 POWER SUPPLY INVESTIGATION
Project Engineer:
The preliminary investigation is complete. Tests indicated that the
transient reduction circuit designed by reduced.
the transient that was troublesome. This same circuit, however, re-
duced the B plus voltage by approximately 100 volts. We are seeking
a method to reduce the transient without reducing the B plus voltage.

2045 AUTOMATIC TAPE PRINTER, TP-
Project Engineer:
One TP-3 printer has been modified for use with the AS-3. Since this
unit is to be used in checking the AS-3 system, a speed control rheo-
stat and hash suppression circuitry was installed, although this
circuitry has not been optimized for operation over the full tempera-
ture range.
The sample motors scheduled for 31 December shipment have not been
received from the contractor. No additional motor checks or TP-3
fabrication was processed during this period.
2069 AGENT RADIO TRANSMITTER,RT-11P
Project Engineer: I 25X1A9a
Circuit modifications for the RT-11A and B transmitters and the
packaging of the 12-volt DC-to-DC converter have been completed.
Delay in delivery of the NiCad batteries held up construction of
the battery pack which is now scheduled for completion on 9 Jan.
The battery pack for the prototype unit will use Sonotone S-107
sealed 2.4 AH cells. This cell is approximately the same size as
the standard "D" flashlight cell. An analysis and appraisal of this
cell is now in process.
2089A HIGH-SPEED COMMUNICATIONS AND PROCESSING SYSTEM AS-4A
Project Engineer: 25X1A9a
The tests are complete on the Transmit Data Terminal. No compromising
interference was detected. The high noise level at the equipment site,
however, could have covered low level radiation. The report is in
process of being published.
M22 AGENT COMMUNICATIONS SYSTEM RS-13B AND RASE STATION CONVERTER 25X1A9a
Project Engineer:
Gears for the RT-13 tuning mechanism have been received. Layout
work is now being processed for this portion of the transmitter.
Radio interference tests have been made on the RP/DC-13B power supply.
Tests indicate that the interference level was acceptable. The re-
port is in process of being published.

Awaiting parts for Selective Calling System
21+7 RECORDER/REPRODUCER MAGNETIC TAPE CB-12
Project Engineer:
An analysis of the subject equipment was attempted. A number of
mechanical and electrical deficiencies became apparent and the tests
were discontinued. The equipment was returned to the manufacturer.
2510 VARIABLE FREQUENCY AUDIO OSCILTATOR IN-1
Project Engineer:
Evaluation of the IN-1 has been completed. Nine units are required.
Although the recent availability of a smaller frequency determining
potentiometer would make possible some reduction in size, it is be-
lieved that the size reduction achieved would not justify the cost
of redesign. Therefore, nine units based upon the present prototype
will be fabricated.
2512 TRANSISTORIZED CONVERTER FABRICATION, CV-2A
Project Engineer: 25X1A9a
The modified Stoddart capacitors required. for fabrication of ten
additional CV-2A Converters are on hand. The capacitors will be
checked, and. if satisfactory, the fabrication of additional converters
scheduled as soon as the workload permits.
2515
MODULATOR FOR TA--1A TRANSMITTER ADAPTER
Project Engineer:
The final report was delivered. to Design Unit this month.
2523 APERIODIC RECEIVER SYSTEM CS-21+
Project Engineer:
The CR-4 Receiver has been evaluated and. accepted. by SPS. Two
comments have been received as a result of the evaluation. One,
a guard. should be placed over the toggle of the AM-CW switch and
two, an inquiry concerning the noise associated with operation of
the threshold. control. Either a guard will be placed over the toggle
switch or the toggle reduced in height. The latter will be simpler
and. reduce the over-all height. This point will be rechecked for
suitability. The noisy threshold. control has been discussed-before
and the solution here is not as simple. Filtering or noise suppression

circuitry has the effect of making the control too "sluggish" to be
useable. Several approaches are envisioned as possible solutions;
however, all require more study and. development than current required.
dates permit. The sponsor, cognizant of this fact, decided to forego
this refinement until time is available for thorough investigation.
The fabrication of twenty units is progressing satisfactorily. There
will be a delay in delivery of the coax switches with 10 February now
indicated as the earliest expected. shipping date. However, all
additional work, including final testing, can be accomplished prior
to receipt of the switches. Switch installation will not require
more than 2-3 days.
Cabling and. mounting plates will be provided to permit five receivers
to be "flat packaged." for briefcase transport.
Although no additional work has been done during this period on the
remaining components of the CS-24 System, emphasis will now be placed
on the completion of the design and. testing of these units. Sample
Haliburton aluminum cases in two sizes have been obtained for pre-
liminary layout study.
Two additional aspects of CRJ operation will be examined during the
course of this program; namely, the characteristics of the receiver
when operated "wide open", that is, without restrictive filtering,
and determination of the useable upper frequency.
2525 TWT/CRYSTAL-VIDEO RECEIVER, CR-21
Project Engineer:
The instruction manual for the CR-21 Receiver has been distributed.
This project will be terminated as soon as all engineering drawings
are in order.
2526 PORTABLE ELECTRONIC KEYER, PROTOTYPES KE/A-9P and KE B 9P
Project Engineer: 25X1A9a
Both prototype keyers are expected to be ready for delivery early in
January. Upon acceptance of the prototypes, work will continue on
the fabrication of two additional units of each type.
