Secret Communications
16, 23 and 30 November and 15 December 2013
 Read the review

In November 2013, Crypto Museum will be organizing a special exhibition focussing on Secret Communication. Many items will be on public display for the first time. For this event, Crypto Museum has teamed up with the Foundation for German Technology in Duivendrecht (Netherlands). The event will be open to the general public on three successive Saturdays.
 
In the three-day exibition, we will be showing a number of well-known spy radio sets, such as the famous British Type 3 Mark II (B2), the RS-6, as used by the CIA, and the German SP-15.

Furthermore, a number of less well-known and much rarer spy radio sets will be on diplay, such as the Finnish/Swedish Kyynel (shown in the image on the right) and the recently discovered FS-5000 that was used by NATO's clandestine stay-behind operations (Gladio). Some of the radio sets will be operational and there will be plenty of time for discussions with the curators.
  
Kyynel M-10X transceiver

Apart from spy radio sets, we will be showing and demonstrating a unique selection of cipher machines, ranging from wartime Enigma machines, through the 1950s and 60s, to modern day text encryptors and secure voice equipment. We even have Obama's current crypto phone!
 
The Enigma cipher machines never fail to attract the attention of the public. In this exhibition we will go a step further however. We will show a wide variety of different Enigma models, such as the Swiss Enigma K and the Commercial Enigma, including some of the rarest accessories, like the Schreibmax printer and the famous Enigma Uhr.

In addition to the Enigma machines, you will be able to see and touch some derivatives of the Enigma, such as the Swiss NEMA and the Russian Fialka, but also the rare TC-52 and TC-53, two Swiss machines developed in the 1950s by Dr. Edgar Gretener and the Swedish Boris Hagelin.
  
KL-51 (RACE) with open lid and expanded paper holder

Many of these machines have never been on public display in The Netherlands before, either because they were too rare or because they had not been declassified. A rather unique item in this respect is the machine shown in the image above. It is known as RACE and was used for many years by NATO. It was compatible with the Philips Aroflex and was also used by the US Army where it is known as the KL-51. See the list below for a more complete overview.

Review
Update 18 December 2013
The exhibition and the cooperation with the Foundation for German Technology was a great success. We had four official opening days for the general public and a closed scheduled one with students of the University of Amsterdam (UvA). The exhibition was preceeded by a closed meeting of the HELL collectors club (the HELL Meeting). In all, we had well over 400 visitors.

On each of the Saturdays we counted more than 100 visitors from all over the country and even from some of the neightbouring countries such as Germany and the UK. We were very pleased to see that the exhibition also attracted the attention from young people, which proves that cryptography is 'hot'.

On the very first official opening day, we had the honour of welcoming one of the members of the original Telefunken design team that created the FS-5000 spy radio set. He had made the long trip from München (Germany) to be reunited with 'his' radio. Although he was familiar with most aspects of the set and especially its batteries, he had never seen the control unit (DSU) before. The latter was developed at Telefunken in Backnang, whilst the radio itself came from Ulm.

Eye witness
On the last opening day, Sunday 15 December 2013, we were visited by Herman Schoemaker, a former radio instructor of the Dutch stay-behind organisation O&I (often referred to as Gladio) who recently graduated on this subject at the University of Utrecht. Herman was accompanied by two former colleagues who worked for the same organisation but had never met before. Herman worked for the Dutch stay-behind organisation O&I from around 1960 until its demise in 1992.

Herman Schoemaker (bottom right) and his two former colleagues had worked with all Dutch spy radio sets from the SP-15 onwards, including the Racal PRM-4150 (in the Netherlands known as DZO-81) and its successor the FS-5000 Harpoon (in The Netherlands known as AZO-90). They were able to provide many intersting details about the operational use of these radio sets.
