Development Field II at Funkwerk Koepenick in 1955 included:
a. Multi-d' eetion sonic depth finder (Rundecholot). Ing. Willy Engel was
in a ge of the project. In December 19) Jig made eiperiments with 25X1
sweep generator with time delay to tong, ft transmitter unit. The
instrument operated on a frequency of 14 and was designed for
horizontal and vertical sounding up to a ante of 8 km. The major
_.problems which ed serious difficulties was the linear charging
of a condense period. The oscillator system of the
sounding devi sed cf four individual oscillators
arranged on a be extended and retracted from the
bottom of ships and rotated when in operation. All records on the project
were secret. Several days before Christmas 1954, a representative of
the Ministry of Interior visited Engel and checked the development status
of the sonic depth finder. He was unsatisfied with the slow progress
and demanded that the activities had to be accelerated and completed
by late 1955? In late December 1954, the project for which funds of
100,000 Eastmark had been planned for 1955 was allegedly cancelled by
another department of the Ministry of Interior.
b. Electronic sighting device also called fish detector. It was planned that
a preliminaryseries of three units be built and that the basic records
for the production be completed. Based on the results obtained in sea
tests, the instrument was to be improved and made ready for production.
c. Fischlupe_ The activities planned were the same as for
the det4cting device reported in paragraph lc above.
d. S6n&c depth finder for sh,llow waters. An operational model was to be
built.
e. Development of oscillators. The materials were to be tested for their
magnetostrictive properties and an output meter for the testing of the
oscillators was to be designed. It was also planned that tests be made
with Manifer oscillators.

%rojects.
a. Transfer of the . -ischlupe`" from development to ;,production.
b. Development of a light sounding device for small fast vessels of the

of I d i rection sonic cbpth finder was not considerel fja&1. This
c.nfusion was a result of different decisions made by the plaaaiia
on one hand and the financial departments and material super ow

De?eiopinent proje!. 'be handled b,,r the TEN L'dro-Acoustic Laboratory of
Development Field II at Funkwerk Koepenick in 1955 included:
a. Multi-direction sonic depth finder (Rundecholot). Ing. .silly Engel was
in charge of the project. In December 1954, he made ecperiments with
sweep generator with time delay to control the transmitter unit. The
instrument operated or, a frequency of .15 kcs and was designed for
horizontal and vertical sounding up to a distance of 8 km. The major
problems which Ircdicpd serious difficulties was the linear charging
of a condenser wi th In a 25 second period,. The oscillator system of the
sounding device was allegedly composed of four individual oscillators
arranged on a plane which were to be extended and retracted from the
bottom of ships and rotated when in operation., All records on the proje-
were secret. Several dajs 'before Christmas 1954, .a representative of
the :linistry of Interior vis?.ted Angel and checked the development status
of the sonic depth finder.. He was unsatisfied with the slow progress
and demanded that the activities had to be accelerated and completed
by late 1955.. In late December 1954, the project for which funds of
