1957
neral - A visit was made to thel
Connecticut on 25 October 1957 with respect to matters pertaining
to the subject contracts. Present were:
measurements., it does not appear to be the cas9, especially when a ground
terminal is missing. The company agreed to repair all equipment., make all
Receivers Serial No.
2. Faulty Equipment - The following RS-3-1/series equipment was returned
to the contractor for repair:
RR/A-11 No. 922A Dial mechanism - Faulty boards
RR/A-11 No. 926A Dial mechanism
RR/A-11 No. 923A Poor sensitivity
RR/B-11 No. 921B Poor sensitivity
RR/B-11 No. 922B Band Switch on HF position.
E)K
25X1
25X1
Transmitters Serial No. Defect
RT/A-11 No. 921A Contact broken off T/R Switch
RT/A-11 No. 917A Intermittent loading Switch
RT/B-11 No. 919B Low Output - Missing Ground Terminal
RT/B-11 No. 926B No Power Output
In fairness too it should be noted that Receivers serial NoSs. 923A 25X1
and 921B,had new switches installed by the laboratory and the sensitivity
may have been impaired by the mechanical switch installation. It was found
that unit No. 923A had aWIF board improperly seated and unit No. 921B required
alignment. Both units were restored to a nominal 7 microvolt AM sensitivity
and accepted for further laboratory checks. With respect to the other defects
there was nothing that 0 engineers could say. Although the company 25X1
maintained that all equipment was completely checked prior to shipment., and
their engineering notebooks did have pages of individual receiver and transmitter

necessary tests, and re-deliver by air express in about a week.
3. Dial Mechanism - We've had considerable difficulty with the dial
tape drive mechanism and several modifications have been made in an attempt
to improve reliability. comment on the latest tape drive mechanism
failure was believed due to the dial tape being a fraction of an inch too long.
4. RP-11 Power Supplies - 1 RP-11 Power Supply (Serial No. 919P) was
returned to the contractor. The need for redesign of the 1.25 volt filament
supply to provide a minimum of 1.1 volts when the AC source is equal to the
low end of any taps was explained. The unit was set up and measurements made
in order to check the accuracy of test equipment. The filament
voltage measured .9 which agrees with laboratory measurements.
admitted that she knew the filament voltage could not fall below
statement to this effect is written in the Instruction Book). The company
asked for time to study the problem and would phone their findings.
5. Personnel - is a new employee at=::~ and my
talks with him were very encouraging. He will head up the engineering
department. is an elderly man, confined to a wheel chair., but
it is felt that he will provide senior engineering supervision that has
long been lacking at
6. Capacitor ~ has been designing experimental capacitors
with a Teflon di4electric. A one mil thickness of Teflon between plates
increases the capacity by a factor of four and provides a 1000 volt
breakdown voltage. (If I remember correctly it takes 25,000 volts to
break down 1 inch of dry air). And of course since capacity varied
inverselqy as the plate separation., reducing the plate separation by one
half doubles the capacity. Thus it is possible to design very compact
high capacity variable condensers,which is what we needfor miniaturized
agent equipment. 0 would like to visit 0 in the near future and
the undersigned suggested that he bring sample variable condensers.
