1. The planned extension ttz VEB Funkwerk Koepenick has begun, The work Will
cost about 1,900,000 DM East. Work has also began along Strarsse 230 On
the construction of a wall 2.5 meters high, which will probably surround
the plant area when completed,.
2. The adnistrative organization of the plant is also being changed. The
present artmental names will be replaced by new Kostenstellen (Accounting
Department numbers Part of the Technical Design Section Teehnisehe
Pro jektierung) (TP) will be moved in the next few weeks. Eventually, this
entire branch of the Koepenick plant will be moved from tte present site
and placed under another administration, VEB Funkaniagena This new VEB is
to be under the direction of Hubert Coenenx. a returnee from the USSR; Hens
Drechsler,, and''ahnke (fnu) s are. to be among those transferred to the new
VEB
Radar
a. On 12 January 19531 two Russians from the SKK,, in civilian clothing,,
visited the marks. They were particularly interested in the radar,.
UHF transmitters,: and navigation equipment. They did not ask any
questions, but immediately after their visit, an order was issued
that a fundamental change was to be made in the radar set It was
understood in the department that it had been decided to make the
aerial moveable in a vertical plane, No new written development
proposals, describing the change were available by 20 January 1953.
In the meanwhile, the aerial already developed had been mounted on
a 30 m tower on the grounds of the plant, and was being calibrated
on nearby landmarks.

10. Branch Works
While the Wendenschloss Strasse plant is the main development plant, production
is concentrated at the Funkwerk Koepenick VEB,. Werk II, Berlin-Oberschoeneweide,
Edisonstrasse,.The building is at the corder of Wilhelminenhofstrasse, in the
former Admos Allgemeines Deutsches Metallwerk, G.m.b.H. buildings. Edisonstrasse
is a continuation of Brueckenstrasse. The works is headed by Ing. Hans-Joachim
Schidlowski' a returnee from the USSR. (He returned from the USSR a considerable
