Telephone and Transmission Installations
1. The wire circuit-connected and carrier frequency telephone technology is
a field of endeavor in which the Tesla enterprises are most heavily
engaged. The results achieved thus far in technology and quality (es
ly durability and susceptibility to trouble) are scarcely inferior to those50Xl-HUM
in the West. In contrast to the Yugoslav communications industry, which
works almost exclusively with foreign licenses, by far the largest number
of Czechoslovak products are based on domestic developments.
2. The export quota in the field of telecommunications installations is very
high, and in the current year it has risen to approximately three times
the amount of the previous year's exports. First place among the principal
purchasers is taken, naturally, by the Soviet Bloc nations., followed by
the markets in South America and in the Near East. The chief customer is
the USSR, to which semiautomatic communications installations are delivered
for the national network. But Czechoslovak cowlunications technology is 50X1-HUM
also beginning to penetrate several West European markets

3. For the wire-circuit communications technology, a fully transistorized
amplifier mounting, U 2 CZ 54000, was produced, which is empolyed in
loaded, if desired two and four-wire cable communications connections.
In all, the mounting contains 12 two-wire and 24 four-wire amplifiers
with all the necessary auxiliary equipment.
4. Another newly developed product is very interesting. It is the carrier-
frequency communications apparatus for short distances, Tesla KNK 6
(photograph #1), which is provided with transistors and for the most
part is finished in printed-circuit technique. With this piece of
equipment a distance up to 23 kilometers can be spanned without inter-
mediate amplifiers. A detailed description and technical parametric
representation are contained in Attachment I.
5. The Tesla VDM 12 high-frequency telemetering apparatus is now in
serial production. It is built for energy-supply installations, to
transmit measuring and control information through high-tension
circuits within a frequency range of 40-300 kilocycles. Description
and data on this apparatus are contained in Attachment II.
6. The Tesla JVT2 single-side-band-transmission high-frequency telephone
apparatus is likewise intended for interlock-circuit telephony. It
also operates in the range from 40-300 kilocycles. Data and description
of this apparatus are contained in Attachment III.
7. The "normal" Teals, program for communications equipment is presented
in the printed material of Attachment IV.
8. There are no new developments in the teletype sector to be reported.
only the Dalibor 302__tape-type teleprinter, which was constructed in
accordance-with CCITT norms and which is already widely distributed,
underwent several improvements electrically and electromechanically.
This, piece of equipment works with the 5-unit code and can be empolyed
by all types of enterprises. The following are the most important
curreetly applicable data on this tape-type teleprinter:
Telegraphy speed, normal: 50 band.
Telegraphy speed, maximum: 400 signals per minute.
Keyboard: According to CCITT
Alphabet: International, No. 2.
9. Among pieces of communications equipment in the broader sense are
included the duplex, voice-frequency and dispatcher apparatuses,
which have received unusually broad distribution in Czechoslovakia.
In even the smallest artisan shop, at least one duplex apparatus for
communication between workshop and office (or residence) can be found.
Consequently the supply of such apparatus on the Czechoslovak market
Is very extensive and versatile, and the techniques employed, as well
as the construction of the individual parts, are very advanced. In
large enterprises the dispatcher apparatuses in many cases are connected
with equipment for control of operations, for telemetering, and the
like. An example of this is given in the dispatcher apparatus for mines
which is described in Attachment V.
Construction of Transmitters
10. In the construction of transmitters (and likewise in the commercial
receiver technology) Tesla is carrying on its former production
program without alterations. In some cases small changes in wiring
and/or-the modernization of the tube or transistor sch me were carried
out.

11. The III TO 010/005 television frequency-gap (test) oscillator, with
100-watt picture and 50-watt sound capacity for Bands I and II, which
is designated as a new product, is only a modification of a type
previously available which was expanded to include remote control and
fully automatic operation. Band IV/V ultra-high-frequency transmitters
are already under development, but in fall 1961 it was not established
whether these transmitters would be equipped with (imported) klystrons
or with tetrodes manufactured in Czechoslovakia.
12. The currently valid list of transmitters, commercial receivers, and
measuring and control panels for sale can be found in the Tesla printed
material in Attachment VI.
13. On the Tesla MT ll mobile radio-range apparatus, the parabolic mirror
is now manufactured frown a ` very ight p 1ast3c of a foamy nature, and
the reflecting mirror surfaces are damped with Al metal.
50X1-HUM
14. As for export activities in transmitter tubes, it could only be learned
from Kovo employees that the export figures (especially for ultra-short-
wave transmitters) for 1961 were more than twice as large as those for
1960. However the figures themselves were not given.
Radio, Television and Tape Recording Equipment
15. In radio technology, with the increase in the production of transistors,
the transistorized small receiving sets (photogrppy #3 and Attachment
VIII) have moved strongly to the fore. The T 61 portable set can be
delivered in a model with two short-wave ranges 20-50 meters, 50-75
meters). It is surprising that a transistorized cable receiver, 314-B.,
is found in the Tesla program. It is also equipped with a medium-
wave and two short-wave ranges.
16. The prize radio set of this year's season can be considered to be the
model 532 A (photograph #1+), with four wave ranges (ultra-short-wave, v-..
short-wave, medium-wave and long-wave), 6 tubes and 7 AM/10 FM circuits.
17. The preference for the short-wave sector is striking, and production
in this area is being very extensively favored by the Czechoslovak
receiver industry. A very strong interest in short-wave reception can
be observed even in the listening public in Czechoslovakia. The short-
wave range of these sets, which in some cases is divided into two bands,
extends (according to the model being used) from approximately 17 meters
to approximately 75 meters. As for Stereo equipment, only a single
model, the "Stereophonic", with a simple record player, has appeared.
For a long time there has been no particular interest in Czechoslovakia
in stereo reproduction (with 2-channel NF- amplifier).
18. The production figures for television sets at present are about 350,000
sets per year. In number of types available, the 1+3-centimeter and 53-
centimeter receiving sets are approximately equal, but in fabrication
and sales the l+3-centimeter sets at present are far out ahead, as they
have been in the past. With respect to technical convenience and also
automatic tuning, the Czechoslovak television sets are approximately at
the level reached last year in the German Federal Republic. The receivers
are built according to OIR (Organization Internationale de Radiodiffusion)
standards with 12 channels and, for export, according to the CCIR stand-
ards with 10 channels. There are no television receivers with ultra-
high-frequency parts or prepared for ultra-high-frequency yet in
Czechoslovakia, but Testa has an ultra-high-frequency channel selector
under development at present.

19. Large combination sets, because of the very high price, have no sales
prospects. Consequently there is only a single model, the Musikschrank
4307 A, which contains a radio receiver, a 53-centimeter television
set and a tape recorder. The electrical and mechanical construction
of the radio and television receivers as well as the tape recorders
can be described as very strong. Externally the sets make a tasteful
impression, and the conventional cabinet forms prevail among the radio
and television sets. Brief technical data on the sets can be obtained
from Attachment IX.
2,r-). The some pamphlet contains the technical parameters of the tape recorders,
in which there is great interest in Czechoslovakia and which are being
offered for sale this year in several models. The most interesting of
these is the "Start" transistorized double-edged variable-width set
(photograph #5) for a tape speed of 4.76 centimeters per second. A
4-sound-track ANP 212 for 9-53 and 4.76 centimeters per second with
a good frequency range (50 cycles to 15,000 or 7,000 cycles) went into
series production in summer 1961. The "Sonet Duo" tape recorder (photo-
graph #6) was intentionally kept simple in construction and fittings so
that it could be offered at as low a price as possible. Attachment X
contains a brief description of this new development.
For broadcasting use by industrial enterprises, a low-frequency amplifier,
type A 2 K (photograph #7), was created, which is manufactured in three
models, for 10, 20, and 40 watts. The amplifier has 7 inputs and operates
within a frequency range of 40 cycles to 15 kilocycles. Depending upon
the model they use, the frequency range can be corrected continuously
or up to a certain, fixed frequency limit. Output voltages are 100 and
1.55 volts.
22. A stereo 2-channel low-frequency amplifier with an output of 2 x 2.5
watts, is offered as another innovation. This is intended for playing
records at home.
Electronic Measuring- Instrument
23. The selection of electronic measuring instruments offered was unusually
extensive. However, it is difficult to identify actual innovations in
,this field, since frequently, with only a small alteration of the measuring
range or a minor alteration in the tube set-up, the same instrument is
brought on to the market as an "innovation". The photographs assembled
in Attachment 11 show such measuring instruments, which 11;ere developed
in 1960 or 1961 but are now actually in serial production and can be
delivered immediately.
24. In electrical and mechanical construction, as well as in quality, there
are no differences between the Tesla measuring instruments and the
corresponding instruments produced in the West. As compared with 1960,
the export of measuring instruments during the past year is said to have
increased by approximately 25%.
25. Tesla manufactures a 15-channel magnetic-tape instrument, which was
originally developed for the Czechoslovak aircraft-safety service, but
more recently several units have been exported. The instrument records
14 information sound tracks and one time trace on a 16-millimeter tape.

High-Vacuum Technology
26. The Tesla vacuum-technology working group rlPv'2 oped a high-vacuum
resistance apparatus, the TVN 600 T.I. for the mass damping of metallic
and non-metallic objects whereby universal dampi.,C is achieved through
a rotary or planetary movement of e o jects around the electrodes.
This apparatus is shown in photograph #8. Several units have already
been sold. A maximum of 3 months for notice of delivery has been men-
tioned. The most important data on the new damping instrument follows:
Maximum damping surface 1.25 m2
Container, diameter 60 cm
Container, capacity 300 1
Electrode heating 100 200 400 800 A
32 16 8 4 V
High-tension discharge 10 kV at 150 MA,
Diffusion Vacuum pump TVD 1000 1200 l/s at 10 mm Hg
Final vacuum better than 10-5 mm Hg
Rotation Vacuum pump TVR 25 28 m3 at 760 mm Hg
Final Vacuum better than 8.10-3 mm Hg
Time for evacuation of the empty and clean apparatus: approximately
15 minutes up to 5.10-5 Iran of mercury
Power consumption of the instrument
10 kw
Weight
800 kg
27. Another new development was the TVP 300 vacuum furnace, which is
intended for soldering materials which are difficult to solder.
28. Approximately 95% of all the condensors, resistors and potentiometers
used in Czechoslovakia by the low-voltage current, communications and
electronics industries come from the Tesla component parts factory in
Lanskroun.
29. The production program of the factory is contained in the general
catalogue in Attachment Xi. A supplement (Attachment 11]) appeared in
1961. The latest component parts developments are described in the
"technical reports" of Attachment XIII.
30. Construction) calibration, tolerance ratings and conditions of testing
of all component parts are in accordance with international agreements.
The products from Lanskroun are regarded by the industry as reliable
and in accordance with tolerances. All normal types in the normal
price-ranges can be delivered at ones even in large amounts, from the
distributing warehouses.
50X1-HUM
31. Development in the component parts field is moving in the direction of
miniaturization and sub-miniaturization. Indeed, in contrast to last
year, unquestionably quite remarkable progress has been achieved in
this field, but Tesla is still quite a distance behind the smallest
measurements achieved in the Western countries especially 50X1-HUM
if higher dielectric strength and larger loads are required of the
very small component parts.

32. A short summary of what has been achieved in the field of minature
parts is provided on page one of Attachment XI.- As for other parts,
development is running its normal course. Quality and technical
parameters are no better and no worse than those of the Western
products.

What is still missing, however, are electronic elements for the
assembling of regulating and control instruments. The development
and manufacture of such structural elements are to begin as soon as
the required large number of transistors are made available to the
industry. This point can be expected to be reached approximately in
the summer or fall of next year. Then they will finally get to work
on the development of elements for digital measuring, controlling and
regulating technology.
