about three days. The individual parts of the unit were placed he follows:
The transmitter and receiver and one indicator unit in the map room, the
second indicator left of the helmsmants stand on the bridge and the antenna
on the upper deck on the rt side. The antenna, a plain-cat-a).uminum
reflector, about 1.5 m w out 40 cm high, was mounted on a triple
braced mast, 14 meters a . Since the Meddo set had been
insufficiently tested i numerous defects were found during
the first experiments a S1JND. Although improvements on the
set would have been of for the experiments, all modifications
were left for the planned seoon lion of the Meddo set. Most faults
were the result of poor quality tubes.
2. The experiments were hampered by the fact that the STRALSWtD was immovable
in the careening. basin and could not be warped to Salzhaff because oil
escaped through the sleeve of the propeller. The ship was loaded at the
bow and the sleeve was dismantled from inside. It was found that the pure
rubber sleeve had been installed w any supporting material. The
repairs were completed on 3 Septemb54 and, after a 72-hour test run,
the sleeve was to be installed. In the careening basin, the experiments
with the Meddo set were seriously handicapped by numerous close targets
and by the very small angle of sight to the open sea. Perfect results
were obtained during the tests up to a distance of 9 nautical miles.'Ir
3. In early September, three development engineers and one projecting engineer
were alternately stationed aboard the ship. For the test run, the ministry
had ojecting Engineer Scheuer (fnu) and the development

No basic development errors but, a ceepe fer tie failures, only mechanical
defects were noticed during omperte a ar October. All defects

again delayed by repeated dismantling of the capstan and repairwork
of the gears. The sailing date on 23 October 1954 was not yet finely

board and controlled the activities there. In a conference held in
October 1954 by representatives of the departments TEA (Technical
Development Antennas), TET.(Technical Development Decimeter and Centimeter
Units), TKM (Technical Construction Measuring Instruments) and TKK (Technical
Construction Miniature Instruments), it was decided that in 1955 two sets
with one indicator,each were to be built in the original shape as measuring
control models. From the valiable results obtained in the experiments it
was concluded that it would be of essential importance to make the length
of the transmitting impulses adjustableuand that, in addition to some basic
constructional modifications, an automatic control of the set would be
required in order to obtain better scanning at a close range.

8. Since long overhauling work was required to repair the clutch, the Meddo set
was dismantled from the STRALSUND and installed in the WISMAR, a 3,000-ton
freighter, in late.November. On 21 November, the WISMAR left for Riga with
Lingenfelder, Munte and Scheuer aboard. By 3 December, Funkwerk Koepenick
had received only insignificant daily reports from these engineers. On the
return trip the WISMAR was allegedly to call at several Baltic and Fast
Prussian harbors.
9. The 1955 research and production plan for the further development of the
PIeddo set was published in late August. Two indicators were to be developed,
one of them specially for long ranges and the other one for average use.
Both indicators were to be equpped with 12" picture tubes which were allegedly
already being produced by the Plant for Telecommunications. In order to
reduce the size of the Meddo set, only miniature tubes were to be used
in the future for the indicator unit. A new transmitter unit with ad$ustable
impulse length was also to be designed.

plant had to wait for the testing data obtained aboard the ships, in order
to evaluate them for the new development specifications to be prepared
by the Projecting Department.
12. In any case, the indicator unit was to be converted to miniature tubes.
These tubes were much better than the types
of the former Oktal series. In spite of all efforts involved, the produetion 25X1
of the pertinent small structural parts was behind schedule and hampered
the development of a smaller Meddo set. Some slight improvements were achielred
with the resistances. Funkwerk Koepenick received models of high 25X1
capacity borc~reated mass-type resistances. Satisfactory results were
obtained in experiments with those small resistances.
13. The TET (Technical Development Decimeter and Centimeter Units) Department
of Funkwerk Koepenick was ordered to develop a reflection measuring
instrument. The order was probably given by the Ministry of Interior.
Additional development orders were received for a rectangular wade generator

the high voltage transformer for the magnetron failed because of flashovers

The fault could be eliminated by the development engineers and the instrument
operated perfectly again. The most distant target measured was allegedly
about 28 nautical miles any. An entioludder unit (sic) installed for
experimental purposes failed during the teats. Screen photography allegedly
indicated that this switching system had proved to be successful. The
coast line and rain clouds could easily be identified.
In bad weather the boat sonetimes navigated
only with the help of the Lieddo set. Even in day time, buoys and ships
were sometimes noticed much earlier on the screen than visually. A pilot

(Seeroijister) would be used for the new indicator unit. The construction
of the second Indicator was probably cancelled for financial reasons. The
new set was to be designed with an impulse lenCth adjustable from 0.05 to
1.0 microseconds. In early October, the first 12" picture tube arrived at
F inkwerk Koepenick. The race type tubes were installed alre's y in Rembrandt
type television sets and provided with a different layer they were to be
used for the improved version of the hedge set. The model tube was tested
for focusing and deflecting ciaaoterietice. In early November, the slant
for Teleoonaunioaticros delivered new picture tubes with various thbkaesees
of layer and color components developed by Mrc. Thurley(fnu) . Some of these
tubes seemed to be better than the ones previously received. They were
being further developed.
11. The departure of Dr Erich Sahnettloeiffel in late September 1954, caused a
noticeable decrease in the over-all projecting and planning activities
for the further development of the Jieddo not. In addition to this, the
