The institute at Kuchino (N 55-45, E 37-58) was officially named Military Unit 568 K, and had the function of developing g~ud building direction finders and other equipment for rad io ooatral. It was placed under Military, Unit 568 of the (B in Moscow on MsJ.a ra Lu??yvnka ulitea, which controlled radio communications. The institute in Kuc ino W M located on the eastern shore of the Pekhorka River. It consisted pf b o groups of buildings which were situated on both sides of the railroad line to Gorkiy? A third building was erected in 1950 - 1951, beoauoe of the lack of space in Area I and Area II, and because of the wish to est,-blteh a production program independent of the plant in Balashikha (i 55049..X 37-57). In April 1952, engineers and mechanics were already workir in Are* III, even though it was not yet completed. The people of the vill. tge called Area II the radio t d a tation. There vas no increase in perSOE el V03-Le the Germans worke the institute. 2. According to Colonel Paramonov (fnu), Military Unit 568 existed during the -war, supposedly in Kuchino. Near Areas I isn 27, there were the remains of old aerial installations. An old undergrounA cable mu. three kilometers north from Area I to a former short wave dipole installation, apparently destroyed by bombs. Immediately adjacent to Area IT, there were the concrete foundations and ground aerials of old antenna towers; the building still showed the insulators for antenna lead-ins. 3. Big and important jobs which required spect*3 unusually large machines were performed by a factory in Balashikha.

No visitors were allowed in Area II. It was difficult to obtain modern components, such as crystal diodes, although even the Germans knew that they were made by Dr. Schloemilch in Fryazino. When the proposal was made to Colonel Paramonov to obtain the urgently needed detectors from that factory in Pryazino, he had great misgivings as to how he could justify his knowledge that the factory produces the detectors, the more so since the Fryazino factory was also not to be informed about the production of the Kuchino institute. 4. Krug Direction Finder The main job of the German engineers employed in Area II until summer 1950 was the construction of a giant direction finder. The project was known under the Soviet designation Krug, that is, circle. The purpose of the equipment was the direction-finding of stations in the 2 - 20 megacycle range. The antenna installation could also be used for the audio direction finding method, known as Wullenwrever, as well as for the visual direction finding method known as Brommy. For both methods., various c sutra-and difference c i compensators., The computers., antenna could also for the radiation furnished. of beams. knew that the be 5. On orders of the Army, an installation of the Krug type was erected in Germany by the Telefunken firm during the war; it operated only in sectors in the directions of knglsnd and Denmark. When Soviet Colonel.Blinderman was informed of this:-, ibttalfttion''..af`ter. the ; -~::;Jaa.,sum ad;; yeretl?of the, designers and ordered the Oberspreewerk (08W), Berlin, to design and develop a similar apparatus. Dr. Karl Steimel, director of the OSW at that time, entrusted Dr. Paul Kotowski with the designing of the direction finder; under him worked Dr. Erich Rheinhold Paul Schuettloeffel on the development of the antenna. His testing ground was the old antenna testing ground near the Beelitz radio station. In October 1946, the design of the direction finder was completed; some parts and apparatus were already built or were under construction. Soviet Lieutenant Colonel Khazin supervised the work. 6. On 22 October 1946, the whole staff was brought to Moscow. From there, Dr. Kotawski, Dr. Schuettloeffel, and Mr.a grad; the engineers Mr. Fegert (fnu), Mr. Hubert t PreRehbock issner,~Mr.sOertel (fnu), and Mr. Riedel (fhu); and the designers Mr. Oertel (not engineer Oertel), Mr. Krueger (fnu), and possibly two or three more, were transferred to Gorkiy. The head of the laboratory, Mr. Braendle (fhu), a Swiss, was not transferred. On 31 December 1946, Dr. Schuettloeffel, Rehbock, and Preissner were ordered to join Military Unit 568 in Moscow. They arrived at Planernaya near Khimki and were billeted in Novogorsk, a simmer resort with 104 quarters (dacha) for ministers and other high officials. There the three Germans had to write various reports about the Krug direction finder. On 5 May 1947, they were transferred to Kuchino. 7. In August 1947, the chief engineer of the institute at Kuchino, Vasilev (fhu) called a meeting to discuss the Krug direction finder, at which the three above-named German engineers and 12-15 Soviet engineers or officers in civilian clothes participated. Lieutenant Colonel Khazin spoke about the erection of a giant direction finder, as ordered by Colonel Blinderman. All data supplied by the Germans as well as their own reports were available. The purpose was to make sure that there would be no mistakes in the design, as the size of the installation demanded much time and money. After a discussion, it was resolved to build the installation according to the original designs of the OSW. A Soviet engineer, who appeared to have a good knowledge S-S-C-R-1-T Approved For Release 2008/03/18: CIA-RDP80-00810A007200860003-8 Approved For Release 2008/03/18: CIA-RDP80-0081 OA007200860003-8 -3- in building antennas, proposed to erect an antenna known as the Faltdipole antenna instead of a cage antenna (Reusenantenna). The proposal was rejected; likewise a proposal made by Colonel Paramonov, who suggested the erection of several small direction finders in place of a large one. The Germans did not participate in the discussion. At the first meeting, the German engineers were told to make a detailed report about the number of engineers, technicians, mechanics, and laborers needed and time required. They asked for approximately 100 men for a period of three months. Their report was based on the OSW/Berlin plan, according to which the installation was to be completed in three months with 30 men employed. The Germans, however, were allowed only three Soviet technicians. 8. The installation consisted of 1e0 antennas, equally distributed around a circle with a 60 meter radius. On a concentric circle with a 55.5 meter radius, a reflector, consisting of numerous vertical single wires, was erected. In order to operate the wide frequency range, wide band antennas were built as vertical cage antennas, ending at the bottom in a point. The base resistance of the individual antennas amounted to approximately 70 ohms. According to earlier calculations by Telefunken, the antennas were to have a counterpoise for the widening of the band width which would act as a capacitance and. which was to be connected through a resistance to the center of the grid. Dr. ScUNCODEDffet had started tests in Beelitz in 1946, to determine the most favorable size of this counterpoise capacitance, but the results of his measurements were not yet known when he was deported to the USSR. He, therefore, applied for a testing area in which he could continue his tests, but this request was denied because of the lack of time and space. 9. The antennas were built and tested by Soviet engineers without consulting the German engineers, but on the basis of the German data. The Germans did not see the antennas before they were erected. When an antenna measuring apparatus was sent from 08W to Kuchino, the Soviet officers refused to accept it, because they said the accuracy of measurement was poor. The apparatus operated according to the substitution method. The Soviet engineers, however, to the surprise of the Germans, used a 30 meter-long test line, which con- sisted of a 30 meter-long boardwalk, covered with sheet iron, over which a measuring wire was stretched at such a distance that a surge impedance of 70 ohms resulted. The Soviet engineers, then, proceeded along the test line with a portable tube voltmeter to find the maximum and minimum voltages. Thus, they demonstrated how they were able to help themselves, even though the method was unusual. The antenna reflector was connected with a ground network, which reached the center of the installation and was electrically connected with the ground water. Forty coaxial cables connected the bases of the forty antennas with the centrally located broadcasting station. 10. The compensator combined twelve antennas bearing toward the transmitter into two groups; they were used to determine the direction of the transmitter. The compensator compensated for the difference of the transit times caused by the circular arrangement of the antennas in special transit time circuits. The transit time circuits were designed in such a way that the transit times were compensated when the waves came in at a 30 degree vertical angle of incidence. 11. The audio direction finding compensator had already been constructed in ON, designed after a Telefunken model. Fifty percent of the parts were completed and sent to Kuchino. There, the compensator was constructed in Area I according to the data and designs of the German engineers. The rotor was continuously variable from 0 - 360 degrees. It was repolished in Balashikha, then electrically examined and balanced by Preissner, and subsequently taken away by a truck. A sum and difference computer was of a primitive mechanical. design, but electrically usable for the wave band of 3 to 10 megacycles and was shipped from OSW to Kuchino. Preissner expanded the range from 2 to 20 megacycles and mechanically redesigned the sum and difference computer.

The rotor of the compensator for visual direction finding was a switch, which could be switched in steps of nine degrees. This compensator was also designed in OSK, but only a few mechanical parts were completed. The con- struction was examined by the Soviet engineers and altered with the coopera- tion of the German engineers. The production was the same as the one of the audio direction finding compensator. An electrical breadboard layout of the sum and difference computer for visual direction finding was built in ON before the Germ engineers were xwwv~e& to the USSR and was shipped to them afterwards. This apparatus apparently was intentionally misconstructed; Preissner, then constructed five usable ones. 13. For audio direction finding, two captured receivers of the loeln type were used in laboratory tests; later, the Soviet engineers procured another com- mercial short-wave receiver which was larger in size and had less sensitiri and image suppression than the JCoeln type. Receivers for audio direction finding were no developed in no. or a visual receiver, a two-channel receiver was needed and the procurownt of a Watson Watt receiver was discussed. Both channels would have to show the seams amplifying factor and the ssmde transit time. At the output of the receiver was a Braun tube, the deflection plates of which were connected to both channels. If the received signal does not come in precisely from the front, but obliquely, the difference of phase of both signals causes a rotation of the line on the screen, which shows the bearing. If the angle is larger than 4.5 degrees, the compensator is switched up nine degrees. 14. Engineer Rehbock continued the research begun in Ofil on the individual parts of the receiver in summer 1947. Later on, Xhazin took over the technical testing research of these parts and transferred the tests to his own laboratory in Area I. He also ordered the removal of the Soviet engineer employed by Rehbock, to his laboratory. Rehbock, therefore, had only to work out analytical tests and supervise Xhazin's doctor's dissertation. X azin came less and less to Area II and finally stayed away altogether. The German engineers knew nothing about the completion of the visual direction finding receiver. Braun tubes with luminous screens were proposed for far direction finding of short- time impulses. 15. In July and August 1947, Dr. Schuettloeffel and engineer Preissner were ordered to inspect with Colonel Blindernm and Lieutenant Colonel Ehazin,a site proposed by Military Unit 568. The site was located approximately 15 kilometers north .of Moscow. Dr. Schuettloeffel rejected the site, because the ground was not level and was covered with trees which could not be removed. A few weeks later, the German engineers were ordered to inspect a site approximately 33 kilometers east of Moscow near the Moscow-Gorkiy railroad track. Dr. Schuettloeffel found this site more satisfactory, but he expressed some doubts, because of the short distance to the track. However, before Military Unit 568 had made a decision, the Air Force had seized the place.. Rhazin said. 16. Subsequently, a third area, approximately 25 kilometers north of Moscow, was inspected and found satisfactory. On the way, the engineers came to a road guarded by military sentries. When they turned into another road leading north, their car and their papers were again examined. Fifteen minutes after they had proceeded once more, they reached a forest, closed in by a board fence which they had to by-pass on the east side. After another 20 minute drive, they reached an open field which was the site to be inspected. When the interpreter was asked about the purpose of the military guards, the engineers were told that this was the summer residence of Stalin. Two weeks later, the two German engineers and a Soviet engineer returned to measure the earth conductivity, the slope of the ground, and the distance to the nearest trees. The German engineers were convinced that the antenna was installed on that site. 25X1 25X1 Approved For Release 2008/03/18: CIA-RDP80-00810A007200860003-8 Approved For Release 2008/03/18: CIA-RDP80-0081 OA007200860003-8 -5- 17. In summer 1951, Preissner, 'while taking a walk, accidentally discovered a complete giant direction-finding installation approximately three kilometers southeast of Area U. This installation had never been mentioned by the Soviets. From a distance of 100 meters behind a fence, Preissner could see the cage antenna the reflector, and a small house with a pointed roof, 8 x 6 meters in sire and ~ meters high. A newly filled up cable trench led from the installation to a little stone house, about 300 meters may., and f~rvm there to a transformer station located near Area II. A piece of a cable found near the cable trench had a diameter of about three centimeters, including the armor. It was a law tension, alternating current cable without a ground conductor; the wire pup was five *illimeters. The transformer station had a special 115 kilovolt tramsformer for the direction finder, which made the power supply station independent of the power supply from the town. The German engineers recalled that a bus with engineers from Area I had passed Area II several times heading for the transformer station. One day Dr. Schuettloeffel said to Colonel PIrownov, the head of Area Its "Colonel, we have wafted on the installation for several years, but we do not know that it works satisfactorily". To which Parumonov answereds "Yes, the installation works; however, we have only exact test readings from the Far last". To another question: "How about direction errors of American stations at different seasons?", Paramonov said: "There seem to be small direction errors in different seasons, but I have no exact information". Portable Direction Yiz:ders 18. After the German engineers had completed their work on the Xrug direction finder, they repeatedly asked, Colonel Zhelesov for repatriation. When Zhelesov finally called on them, he did not mention their release, but declared that he had a new and interesting assig m ant for them. They were asked to look for unknown radio cosammications in the wave range between three centimeters and 500 centi- meters within cities. The Germans declared imwediately that, because of the quasi-optical behavior of these waves, it would be almost impossible to accomplish an exact direction finding, since buildings hinder transmission and direction finding errors would result through reflection. Zbelesov answered that he knew this, but that this was just what be wished the Germans to think over and come up',with,adequate suggi stiens~ 4 he,,returu~ed a. few days later, the German engineers reported that the aforementioned difficulties could be greatly eliminated through the application of as any portable direction finders as it is possible to use. After the determination of the appro imate position, the exact position can then be determinated by these portable direction finders. No mention was made about installing these apparatus in vehicles, nor were there any corresponding tests or installations performed. The German engineers were never consulted about audio receiving sets, receiving systems for the one centi- meter wave range, .or about the longest wave direction finding. 19. Following this meeting, Colonel Paramonov was directed to discuss with the German engineers the details concerning the construction of the necessary apparatus. The apparatus were then marked by the Soviets as follows: Tpe Wa DIZI2-1C 3cm-9cm DIMI2-1D 9cm-50 cm PAID 1 50 cm - 100 as ACID 2 100 cm - 200 an P14D 3 200 cm - 500 can These designations were also engraved on the front data plates. The antennas of all five apparatus were developed by Dr. Schuettloeffel and the receivers for the DIZI 2 - 1 C and DFZI 2 - 1 D by Preissner. The receivers for P1(D 1 to PHD 3 had not been completed when the Germsan engineers left in April 1952, since the Soviets had constructed those receivers designed by Rehbock in such a way that they were unusable.

Colonel Paramanov also charged Pre issuer with the supervision of the con- struction of the DZZI 2 apparatus. For that p~c~-pose, a supervising con- structor and two assistant constructors were assigned to him. These cone structors were employed only for the construction of certain parts and they had no knowledge of the construction of the satire appatratus; they also had only little experience in precise mechanical work, 1444 gitbriiatfaj gsiir racks directly from plait of gear-vheel transmissions. A workshop furnished with two lathes and two drilling machinesr as well as five mechanics was provided for them. The parabolic reflectors were srmutlactursd is )alash"cna. A large one meter radius reflector was made by a foreign plait, astp~e the salver coating of several individual parts. The UVI 2 - 1 C and UrII 2 - 1 D were constructed to be used as laboratory standards and as acceytence standards; the designs for their reproduction were an hand, In October 1951, a list of materials required for the production of ten to twenty apparatus was prepared, but the German engineers never learned whether the materials were actually delivered or not. 21. In October and Iotnemober 1951, two or three Soviet engineers of Military Unit 568 took over the two DIRSI apparatus, For that purpose, a one meter radius parabolic reflector was moounted an a roof an Ares II; the transmitter stood inside the building. The Soviet engineers ' tested the direction finding accuracy from a one kilometer and two kilometers distnace; they also made tests from the woods, They declared that the sensitivity of the apparatus was too low and demanded to knots w y no beterodyne receivers were built, to which the Germans answered that they had no order to do no. In about mid- 1951, Soviet interest in portable direction fin ors declined, because they became more interested in relay stations. Description of that M&A .. 1 C sad - 11 22. The receivers of the hl)'LT apparatus are sdjuated for the reception of un- modulated, amplitude dated, frequency modulated, and keyed transmitters. A vibrator with approximately 350 cycles prdvid d, after rectification, for the reception of uzaandulscted and frequency modulated carriers. Amplitude modulated transmitters can by heard through headphones. A 1.2 to 1.8 milli- volt input voltage is necessary for the full, goals reading of the indicator instruments. The threewstegs loxeregwency amplifier had a transformer input and supplied an amplification of appJnmcimitely 10000. The emplifier was built as a rack-mounted equipment end, therefore, could be used for both apparatus. It was equipped with miniature tubes and in the output stage with two commercial battery tubes. A 1.5 volt dry?cell battery and a 120 volt anode battery operated continuously from six to eight hours. The reception of vertically as well as horizontally polarized waves vas accomplished by rotating the electromagnetic horn aadthe dipole heads. The =1 2 - 1 D apparatus had two interchangeable dipole heals fOr the 9 to 20 1p to 25 centimeter wave ranges. The receiver of this apparatus weighed 16 to 20 kilograms, and the stand, including the parabolic reflector, apps- imately 40 kilograms For shipping, the apparatus could be taken apart and packed in a protective cover- ing of brown, watertight canvas. It was also planmded to ceouflags the reflector while it was in operation with a nont?transpsrent synthetic sheet; such a covering, however, 'test not obtainable. Description of the N 1, 2 23. The receivers of the direction finders PlO 1, 2, and. 3 were set up for amplitude and frequency modulation. The sensitivity of the FIID 3 receiver was several microvolts; the other two receivers had not yet been tested. The reception could be heard by oenas of radio or telephone lines; the field intensity was registered by an instrument. A six.-volt storage battery and a 300 volt anode battery supplied the power, and supposedly weighed approximately 30 kilogram. The input and oscillator circuits of the apparatus P1* 1 were resonance Approved For Release 2008/03/18: CIA-RDP80-0081 OA007200860003-8 Approved For Release 2008/03/18: CIA-RDP80-0081 OA007200860003-8 cavities and had an intermediate frequency of apprao~l tely 100 megacycles after the first heterodyning, and 10.6 megacycles after the second. M 2 had 50 megacycles after the first heterodyning and 10.6 megacycles after the second. Two dipoles at a 45 degree angle with the horizontal were used as direction finder antennas, with a spacing of 0.60 meter, one meter, and approximately two meters for all three apparatus. The antenna system, could be used in either of two vat's s maxima= or minima readings. The antenna for the NO 1 was provided with a reflector screen which was behind the dipoles. The identification of signals fi the side was srde possible with the other two apparatus by a lengthening of the conducting cable to om of the dipoles. To camouflage the installation daring the operation period, as requested, it was planned to install the antenna for the $0 1 in a large plywood box of approximately 100 x 60 x 35 csntiassters. po practical solution, hoverer, for camouflaging the other apparatus could be fauns. Mg MISI&M 2h. Iron the beginning of 1950 until the end of 1951, the German engineers worked an the development of three very high frequency radio stations and they named them relay station 1], 2, and 3. The Soviet designation losmat was given to relay station Ia. 1. The Gsrman engineers aid not build smell transmitters without receiver aerials. Relay ataOOLS loo. 1 25. =arly in 1950, Colonel Psrasmonov ordered Dr. Aahusttloeffel to design a wide. band dipole antenna which could be sewed into the clothes of a person. At first no reason was given to him, but after repeated inquiries he received a small two- W radio set,which vu similar to a cartridge pouch and could be fastened to a belt. Is vY also cautioned not to mention this development even to his German colleajgves; later, >arer, they too worked on the project. This dipole antenna, developed by Dr. 8ahuettloefflel, was designed as a double Y antenna, in order to attain the necessary band width. The upper parts of the Y reached from the back of the belt to the shoulders, the lender parts of the V reached into the pants. Prsissner had. also developed a small three-coil transformer. At first, the Soviets had used only a single dipole without a three-coil transformer. The new construction of the antenna increased the range radius of the station. The Soviets called the prototype of this apparatus garnet I, a later model with higher power, met B. The Germans were left in ignorance about Soviet production and further designs. 26. The Kmat apparatus could be tuned into a stables frequency between 87 and 103 megacycles. The transmitter vas quartz-stabilised; that is, an eight megacycle quartz crystal vas excited with the third harmonic, and this frequency was doubled in two stages so that a final frequency of approximately 96 cycles resulted. The output trams'iision of the Xammt I was approximately 40 mdllt. watts, and of the iamet B, approximately 130 mi.lliwatte. The receiver had an aperiodic first stage, a superregenerative rectifier, and two lore-frequency stages. The receiving tubes were miniature tubes which had an approximate eight millimeter radius and a 35 millimeter length, but were without a base. The transmitting tubes of the grommet B were miniature tubes with an 18 millimeter radius and a 55 millimeter length, but with a base. The microphone, having an approximate 22 millimeter radius, could be fastened to the coat; the earphones, made as flat-type crystal receivers, could be worn under the coat, on the shoulder near the ear. The apparatus, built to fit the body, was 150 milli- meters wide, 70 millimeters high, and 35 millimeters deep. Connected to it and attached to the belt were, to the right, an anode battery, and to the left a storage battery. Both batteries were 70 millimeters wide. All parts were covered with an uniformly colored cauvse The sewed-in antenna could be con- nected with the transmitter by news of a double.pole plug.

While Dr. Schuettloeffel wee engaged in the development of a dipole antenna for the Koaet, engineer Rehbock received an order front an engineer of Area I to develop a portable transceiver. It appeared that this apparatus had already been worked on in Area I. Rehbock received such concrete data, that, after a few calculations, be could begin with the development and construction of the portable not. While working on it, he vas told that his set should be able to receive the signal of the Komet and should transmit it amplified to an adjacent frequency. The order was urgent. The receiver vas a superregenerative receiver and was more sensitive than the one of the Komet; its frequency range was 87 - 103 megacycles. The output power of the transmitter was approximately three watts; the distance between the transmdtting and receiving frequency vas 6.5 megacycles. Since the receiver and the transmitter were to operate on the same antenna, it vas necessary to develop a transceiver filter. The power egeipment, a six volt storage battery and a 300 volt anode battery, together with the apparatus was placed in an ordinary suitcase covered with a canvas. It was 60 x 45 x20 centimeters in use. The transmitter automatically out in when a receiving signal enema in which made special handling unnecessary. Depending on the demands, the apparatus could operate continuously for approximately three hours. It vas originally intended to use a built in box- antenna which was designed by Dr. Schuettlosffel. But because of its in. sufficient radiation property, a telescopic antenna was used later. It was also possible to connect it with a car antenna. Relay Station No. 3 28. While Rehboek was still working on relay station No. 2, he received a new order to build relay station No. 3. This station vex to have a supersensitive receiver and a powerful transmitter and was to be supplied by the power network. The frequency range vu to be the same as that of the two other relay stations. The heterodyne receiver operated with an intermediate frequency of 10.6 mega- cycles and with frequency modulation. The input sensitivity was not tested. The transmitting power amounted to approximately ten watts. It was also possible to connect the station to a public circuit. A vertical half-wave dipole served as an antenna, its lower patt was built as a seal connection to the dipole. 29. In November and December 1951, the Soviets tested the relay stations. Relay Station No. 1 was placed in Area I. A truck with relay station No. 2 circled around outside of Area II, in which the antenna of relay station No. 2 was mounted on its main building. The tests supposedly showed that ranges of five and ten kilometers were achieved. Miscellaneous 30. According to Captain Cherkasow, one building in Area II was used as a prison. The German engineers repeatedly noticed that a truck, similar to a German police truck, would stop in front of that building. In summer 1951, packages marked Military Unit 533 or 522 were unloaded from such a truck. During summer 1950 or 1951, the German engineers heard the sound of German records coming from the building. When soon after, Cherkasov asked then if they knew a Dr. Splechtna they guessed that their colleague was put into this building. The Germans were of the opinion that those prisoners whom they never saw, were sent to different working places every day. Splechtna, who was set free at the beginning of 1953/195, confirmed their opinion. Re also told then that the head of the Military Unit, known by the nicknaame 'The Iron One", was dismissed and was reduced from his rank of major general. Splechtna saw him working as a laborer in the Marfino concentration camp. Re said that the general was not kept as a prisoner, he could live outside the coup, but his work was very hard and humiliating. Other inmates of the camp,, for instance., would call to him: "Comrade Major General, fetch me the battery". After the fall of Beriya, several of the other Soviets, such as Dobrosyanskiy and Ihazin, were arrested.

Kacherin and ICazarinov had special identification cards to enter Area I. The German engineem were kept very much to them- selves, even within Area II. After they arrived in Xuchino on 5 )by 1947, they were allowed to begin to work only after their working places in the main building were so arranged that they could have no insight into the working places of the Soviets; they started to work on 1 July 1947. From spring until fall 1948, they worked in two rooms in their own quarters; from fall 1948 until spring 1950, they worked in a plywood shelter; and sub- sequently until their departure, in a house that was completely separated from all other buildings by a board fence. 32. The Soviet officers, as their chiefs, were reserved and carried on no private conversations. The opinion of the German engineers 1with respect to their professional kmo 'ledge, iris almost41vI's accepted, but they werenever praised. Only Colonel Paremnov would speak with them about private matters after he had discussed technical problems with them. The people of the town, in so far as they did not belong to the Military Unit, sought to contact the Germans, but they were not allowed to enter the German quarters. The German engineers, however, accepted invitations to the Soviet bows., but without the knowledge of the camp authorities. When the Soviet people found out that the Germs had been forced to cams to Ihichino, they becems more con- fident and showed their symgethy openly. During the visit of a Soviet driver from a macaroni factory, he abed a German engineer to repair his broadcast receiver, especially the short-waave parts. When the German told him that he too had difficulties in getting a static-free short-wave recep- tion, the driver told him to listen at 0300 hours on short-wave when the British radio could be heard relatively well and static-free in the Russian language 33. $ Military Unit 568)Xoscow, Malaya Lasby ka.
