Secret Communications 2
12 and 19 November and 3 December 2016, and 14 January 2017

Following the success of the exhibition Secret Communications, back in the winter of 2013, Crypto Museum has once again teamed up with the Foundation for German Communication in Duivendrecht (near Amsterdam, Netherlands) for the exhibition Secret Communications 2. This exclusive exhibiton will be open to the general public the following Saturdays:
 
  • Saturday 12 November 2016
  • Saturday 19 November 2016
  • Saturday 3 December 2016
  • Saturday 14 January 2017
On these days, we will be open from 10:00 to 17:00 and admission is free. Furthermore, coffee, tea and sandwiches will be available free of charge. We will be showing an exciting collection of cipher machines and spy radio sets, some of which have never been on public display before. Check the overview below to see what we have selected for you. Large groups may apply for a visit outside the regular opening days and times. Contact Arthur Bauer to make arrangements.

12 & 19 November & 3 December 2016 - Kloosterstraat 23-25 Duivendrecht - Netherlands

 
Cipher machines
Like in 2013, we will be showing an exciting collection of rare cipher machines, some of which have never been exhibited in a private collection before. How about the British Typex Mark 23 shown below? It was used during WWII by the British Army for messages at the highest level and has five coding wheels and two printers. Strangely, it is still considered classified in the UK today.

Another exciting new cipher machine in our collection is NOREEN, a one-time tape device that was developed shortly after WWII as a solid-state alternative to the wartime ROCKEX. The machine is unbreakable as it uses a noise-generated key tape that is at least as long as the message itself. But unlike other machines in its class, it uses a very uncommon 6-level punched paper tape...

And of course we will be showing the usual suspects, such as the famous German ENIGMA cipher machine and some of its rare family members. After all, what would a crypto exhibition be without them? The ENIGMA was used by the German Army during WWII and was thought to be unbreakable. Yet it was broken at large scale by the Allied Codebreakers of Bletchley Park.


 
Spy radio sets
Apart from cipher machines, we will be showing a nice collection of spy radio sets and their accessories. On this occasion will be focussing on the history of the secret Dutch Stay-Behind Organisation O&I and the equipment they used during the 46 years of their existence, from the very first three-piece valve-based set, to the last fully digital automatic one with built-in crypto.

The Philips/NSF ZO-47 spy radio set, developed in 1947

Some of these items have been kindly given on loan by other museums, such as the first and only Dutch spy radio set ZO-47 shown above. It is probably the only surviving example of this radio set. Another example is the FFS-7 below, which will be shown in its original cache container. The latter has kindly been given on loan by the dutch ham radio museum Jan Corver.

The FSS-7 (SP-15) spy radio set in its original container

Apart from highlights of the former O&I network, we will also be showing a selection of rare spy radio sets from former Eastern Block countries like Czechoslovakia, Yugoslavia 1 and Hungary. Some of these have only been recovered recently and have never been on public display before.

Czechoslivakian SIRIUS spy radio set, used during the Cold War

 
  1. Stricktly speaking, Yugoslavia was not an Eastern Block country during the Cold War, as it was not part of the Warsaw Pact. Although it was a communist country, it was neutral and was never part of the USSR either.

Super Enigma
People interested in the history and function of the Enigma Machine will no doubt have come across the 'super enigma' built by Tatjana van Vark in 2003. Under the name Cryptograph, Tatjana has provided a beautiful example of how art and technology can go hand in hand. If you want to see this machine 'in the flesh', now is your chance. For the first time, Tatjana will be demonstrating the Cryptograph on the following opening days of our exhibition:
 
  • Saturday 12 November 2016
  • Saturday 3 December 2016

Impressions
Saturday 12 November 2016
Saturday 12 November 2016 was the first opening day of Secret Communications 2. When the doors opened at 10:00, some people were already cueing up at the entrance. We had visitors from France, Denmark, the USA, the UK, Belgium, Germany and, of course the Netherlands. Below are a few photographs of this day that were made by our German friend Karsten Hansky. THANKS!

Wednesday 16 November 2016
For large groups it is possible to arrange for a visit outside regular opening hours. Wednesday 16 November 2016 was such a day that was scheduled especially for a group of 30+ students of Amsterdam University. And they didn't come empty handed as the photograph below illustrates...

Entirely in style: a large cake with the image of the Lorenz SZ-42 (still our our wish list)

 
Saturday 3 December 2016
The last opening day of 2016, on 3 December, was an great success. Some people were already queing up when the doors opened at 10 o'clock. In total, we counted just under 200 visitors this day, which makes it the most successful one so far. Luckily, Jan and Marjan Rijnders were present to help us out. Thanks! Below is a nice selection of photographs that were made by Gerard Vos.

The doors have just opened but we already have a full house
