Exhibits New Reshuffled

after the last Secret Communications 2 event

held between

12 November 2016 and 14 January 2017

Such an occasion is a favourable moment for some form of reshuffling artefacts, as well as focussing on never before dealt with subjects, and displaying some interesting devices differently. 



A view from the perspective of new visitor, towards the main exhibition venue

On the left-hand side we see a gathering of GEMA/Siemens radar modules, mainly dedicated to Jagdschloss; but it has to be noticed, that such devices had been operated in most GEMA radar systems.



Viewing it from the opposite side

The transmitter in front was once  was part of a Jagdschloss radar system.



Turning my observation around

The top shelf shows a replica of a so-called Hülsmeyer receiver of about 1904.



Walking a bit towards the first exhibition room

On the left, the X-Gerät a test module once operated in conjunction with off-shore Seetakt systems. Next to it, below the so-call R-Gerät, the universal medium- and high voltage power supply to all GEMA systems, including those modified by Siemens.

The dark-blue/grey box on the left-hand side is the Nachtfee (FuG 136) console.



On the left-hand side the Gemse receiver, part of the FuG 25a I.F.F. system, in this context being part of the Nachtfee operational chain



Focussing at the aircraft related systems

On the right-hand side the simulated, hypothetical, Nachtfee aircraft display. It works like it most likely once should have done so. Albeit, we bridge information over a distance of 3 metres, instead of 250 à 300 km.



On the right-hand side a better vision of the simulated aircraft system looks like. Next of it we notice a reconstruction of a FuG 25a aircraft substitute, but functional. On the right-hand side a better vision on, as to how the simulated aircraft system might functioned. Next of it left we notice a reconstruction of a FuG 25a aircraft substitute, but functional.



This 'Funktisch' originates from a Siebel 204 aircraft; a (longer) distance small passenger airplane.

It took me decades to obtain it.

A curious story is about it.

In October 2015, I have already had in my hands somewhere in France; but it proved not to be possible to obtain it; among the desired devices was also an EBL 3F receiver.

However, two weeks ago I bought first an EBL 3F and discovered that it for 100% must have been the same receiver which I have had in my hands before. The second device the according FBG2 tuning selector, also this device I had in my hands once. I contacted the seller and he confirmed my suspicions.



It is our desire to implement the new devices within the existing FuG 10P (FuG 10 + EZ 6), with the blind-landing gear just obtained. And partly controlling it from the Siebel 204 'Funktisch' 



This corner shows a blind-landing beacon upon which aircraft once could approach the landing strip accurately. Left of it, a blind-landing test set (PSU0-B). I have seen once a demonstration, where the various parameters of FuBl can be demonstrated. That is where we are currently going for, Deo volente, of course



Tonschreiber b (TonS b), on display



Looking at it from a different position



Underneath left the quite rare PNG 2, power supply. This power supply could supply FuG II and III and some other gear, at choice. For it on the right-hand side of it, is, a cover-disk which can be rotated for the various set under consideration




The left-hand side of my favourable 'Rariteiten Cabinet'



Viewing a part of the 'Army' (Heer) display

The white card in front of one of the Feld Fu sets actually is a description or registration card, fixed by a cord kept at the case of an artefact. The application of a cord was a most successful 'Invention' as when visitors have left, we find most apparatus with visible cards standing in front or just next to it. When taking photos, the brief information is instantly attached as well.



The 100 WS with attached dummy-load, standing on top of a power supply, made on behalf of the Norwegian post war services. It had been designed and manufactured in Germany; it is perfectly matching to their future application



Fu 5 mounting on the right-hand side, being reshuffled as to get a better vision on it



This corner shows partially, on top how the set looks like from the front side, below what is visible inside the case



Turning the camera around, and viewing the centre of my favourite 'rarity cabinet'



Looking at it differently



Turning our attention on to the 'telephone corner'



Viewing it from alternative angle



This display constitutes a unique theme: "carrier telephony". We would like to demonstrate as to how two separate telephone signals can pass through a single pair of wires, without  mutual interference

Don't think this is crude technique! As to give you a brief idea what it is about: Consider two point locations A en B

Imagine: from A → B A sends in USB, whilst the post B → A sending in LSB. The carrier oscillators also functioning in synchronous detection, providing a quite good LF speech signal.

Our plans: facilitating at some points in the rooms 'field telephone' sets, linking them through the Tfb system and handling the different connections by means of a so-called 'Klappenschrank' acting as an exchange centre. All, Deo volente, of course.



In the centre a genuine Tfb power supply, but with stabilised 12 dc

No way, a lot of commitment is waiting for us.

Who would like to volunteer, bringing this project to a good end?



 Turning our attention towards different techniques



Taking a different position

The blue shining in the rear of the S 406 S U-boat transmitter might originate from reflection, because Perspex is a clear material.



Looking at a 'Hütte Peiler D/F receiver', with attached gonimeter

The two masts left and right are genuine Adcock masts, it should be a number of 4, but in the 1970s I obtained, from Denmark, only two masts. It, never mind, shows a tiny bit what it is about.



After a long time, the Radio Suite Case Station being on display again; but shown in a more favourable setting



 Viewing the mainly naval equipment

Please notice the blue reflection in the glass window in the rear, here originates the form of reflections from! Definitely originating from the different light-temperatures with which our digital camera has to cope with.



Without comments



Camera has been turn slightly around



The radar-signal-search DF corner

From right to left:

NAXOS FuG 350Zc; EO 281; Korfu RX latest version with plug-in modules. In our case covering the S-Band; both Samos and Fanö VHF - UHF search receivers. Both radar signal search corner



The Telefunken T8, Magnetophon project, but is still causing headaches 



Before leaving this room, viewing the 'army (Heer)' corner again



This side of the room hosting the Berlin- and Würzburg radar systems



Too many devices to be explained, in particular



What do you recognise?



Against the rear wall on the left FuG 101a to the right Liechtenstein SN2, but the two lower antennas being demounted for safety reasons



In front left K 12 Siemens gyro system, genuinely adapted for application within a mini submarine type Seehund (Typ 127). This gear was once captured from a boat laying on shore at the territory of the Dutch "Hoogovens", once part of the: 'Festung IJmuiden'



 Find out yourself 



The 9 + 1 channels UHF carrier telephony set, known as Rudolf, DMG 3aG



Hagenuk corner, showing Ha5K39b including power supply and, in the centre, a Ha15K42



AN/APS 15A among Philips gear

In Germany also known as: Meddow Gerät



In front the Zeitdrucker  38, likely measuring the nuzzle velocity of gun barrels



 Our WT 40 rig, providing  6  FSK telex channels over the single bandwidth of a regular telephone voice channel



On the left the FuG 102a display dismantled, as to show it beautiful construction, on the right-hand side the gyro platform of a V 1



Turned the camera around, viewing the Würzburg Fu SE 62 D set-up




Taking a closer look at the FuG 102a parts



Returning to the main hall again



The dual Siemens Geheimschreiber T 52d setup

We may suppose at least - this is not a common set up.



Viewing it slightly differently




The Lo70KL40 rig, in the background the Körting KST, the German version of the HRO receiver



Closing today with another highlight
