1. The disturbances of 17 June 1953.
The events of 17 June 1953 in VEB Funkwerk Koepeniok followed a pattora already
familiar in other large Berlin works. The following points alone seem worthy
of record*
a. On 17 June, the following were elected to a strike committees
Dr. Bernhard Vinzelberg
Dr. Rudolf Kaiser
Erich Trippmaoher
Kurt Booker
Siegfried Berger
Hama-Joaohim toeffelbein.
be Arrest of these men was threatened by the SSD (State Security Service) on
18 Juno. Sections of the works thereupon threatened further strike action
and the SSD desisted, merely making various people sign-statements that
there had been no arrests. Kaiser, Vinzelberg, Berger and Booker were then
arrested on 20 June 1953, Booker was released after two days. Drs. Kaiser
and Vinzelberg were released on 11 July 1953, but Siegfried Berger was still
under arrest on 20 July 1953. Loeffelbein was dismissed from the works.
Drs. Kaiser and Vinzelberg have also been forbidden to enter the Funkwork
again.1
o. Several workers who had been prominent in the strikes were hidden, by their
colleagues for several days to avoid arrest,.
The strikers were very disappointed that the West had unoon4itionally rs.
turned Otto Nusohke, East German Deputy Minister President, who wag pushed
over the boundary into West Berlin during the disturbances. They Would
have liked to have seen him exchanged for somebody like Walter Lingo# kid-
napped from West Berlin in July 1952.2

e. It was noted in the works that Wilhelm Grimm held back from the demonstrations
of 17 Jame. He was, however, forced to march with the strikers.
f. Feeling in the works in early July was still turbulent. Everyone was hoping
that Berlin would be one city again.
2. Personalities*
a. Erich Huettmann, radio development specialist, left the works for the Aero-
logisches Observatorium Lindenberg in June 1953. He will be concerned there
with radiosonde work..
b. Hubert Preissner has left the works for the West.
Administrative changes.
The Funkwerk Koepenick is now no longer subordinate to the Ministry of Posts and
Telecommunications. It has been transferred to the Main Administration for Radio
and Telecommunications of the Ministry of General Engineering, Berlin W 1,
Leipzigerstrasse 5-7. (Tel. 22-02-01) (Hr Radio and Fexzimeldeteobhik, Ministerium
NO Allgemeine Masohinenbau). Head of the new HP is Hero of Labor Adolf Hegemann,
former director of RFT Fernmeldewark Arnstadt (1952).
4. Radar development.
The Kollisionsschutzgeraet (anti-collision equipment) - the only radar equip-
ment being developed by Funkwerk Kopenick is now taking final form. Draw-
ings for series production are now being made. It is not"kmorrn where series
production will take place. It has been noticed, however, that representa~+
tives of the Sachsenwerk Radeberg have several times visited the Fuakwerk
to take measurements of various parts of this equipment.
b. The PRF (Impulsfolgefrequenz) of the Kollisionsschutzgeraet is 1000 cps*
c. In its final form, the paraboloid reflector is not vertically moveable.
It can only rotate in a horizontal plane. Its normal rotation rate is 24
revolutions per minute.
d.. The apparatus has a single display tube, marked with non-linear polar
coordinates. The distance represented by the spacing between'
etween' the edge
of the tube and the first ring is 30 sea miles. Thp distance represent-
ed by the spacing of each of the two next rings is also 30 sea mileq:

6. Fuukwrerk Koepeni ckt s very long wave receiver (Laengstwrellenempfaenger) .
This receiver (ZAFT task K2-91)has four frequency ranges. The lower frequency
range, from 15 kes up, is for use at sea; transmissions of interest to seamen,
such as time signals, can then be picked up on this range. This apparatus has
the type number Lea-10.
7. Wilhelm Grimm+s work.
No great progress has been made with Grimnts navigational system work, as no
firm orders have reached the Funkwerk from the State Planning Commission, The
Funkwerk was told by this Commission earlier that the Decca system, rather than
any other, was to be built, starting this year, but no further detailed orders
have come through*
8, East German tube list.
The Funkwerk Koepenick recently received from Dr. Alfred Schiller of Werk "HF"
a list of tubes available in East Germany and some notes on those which were
not to be used because they were not available. The list was divided into three
categories:
25X1
25X1
Funkleitfeuer (radio control beacon) and Fun.kfeuer (radio beacon).
a. Funkleitfeuer and Funkfeuer are recognised German terms for ce#btain forms of
Ji/F equIpmen . They are not Funkwark Koepenick code names.
Funkleitfeuer (ZAFT tast K2-33) was planned to have a power of about 100
watts. 14o-more work is being done on it at the moment.
Funkfeuer (ZAFT task K2-34) has a power of about 100 watts also. One unit
has been-installed at a point near Mukran, which is 5 kms southwest of
Sassnitz on Ruegen Island. It is aligned so as to radiate along the channel
to Sassnitz harbor mole.. The angle of 244.5? has been mentioned in caul
ne6ti cn-v+rith this installation, but it is not known what this angle repre-
sents. The range of this apparatus is understood in Funkwerk Koepenick
to be 15 sea miles. It is not yet known on what frequency it operates,

a. Tubes which should preferably be used in any new equipment.
b. Tubes whose use may temporarily be permitted in new equipment.

9. New Funkwerk telephone directory,
A new telephone directory has just been issued. As part of the policy of *watch-
fulness" (against spies and saboteurs), this has been made an aocountable 'Confid-
ential document, to be locked in a safe at night. 4r

This appears to be the bearing of Mukran from Sassnitz.
This is typical of present policy. Further examples are: oon;plete lack of any
East Berlin public telephone directory; suppression of all addresses from the
latest East Berlin Humboldt University calendar; refusal of the authorities to
issue a new Academy of Sciences telephone directory,
