Czechoslovakia
Czechoslovakian spy radio sets
 
During the Cold War, Czechoslovakia, or Czecho-Slovakia, 1 was a federal state behind the Iron Curtain. It was part of the Warsaw Pact and had two major secret services, both of which had strong ties with the Russian KGB: the Státní Bezpečnost (StB), which was the secret state police, and the Zpravodajská Správa Generálního Štábu (ZS GŠ), the military intelligence agency. In addition, there was Správa 1 (Government Dept. 1), the secret intelligence agency. The main task of these three organisations was national and foreign espionage (more...).

In most West European countries, the Czechoslovak embassy acted as the cover for their covert espionage activities. Apart from the ambassador and a handful of assistents, one way or another all embassy personnel worked for the StB or the ZS GŠ, often under the cover of being a diplomat, a cultural attaché or a press attaché. Intelligence gathered by those 'diplomats' was reported to the so-called Resident, who would pass it on to Control at headquarters in Prague.

It is little known that the StB and ZS GŠ were also active outside Europe, in countries such as Australia, the US, Congo, Angola and Iraque. Czechoslovakia was for many years the only Warsaw Pact state with an embassy in Australia, for example, as a result of which they were even carrying out operations on behalf of the Russian KGB. In many cases, clandestine short-wave transmitters, or spy radio sets, were used to pass coded messages onto Control in Czechoslovakia. Below are some examples of such equipment some of which was re-discovered by Crypto Museum in 2015.
 
  1. Following the fall of the Berlin wall in 1989 and the subsequent collapse of the Soviet Union in 1991, the state of Czechoslovakia was peacefully dissolved into the Czech Republic and Slovakia on 1 January 1993.

Source
In July 2015, Crypto Museum received a large donation from a 'former user' of equipment and related documentation, of a variety of spy radio sets and other covert equipment that was used by the intelligence agencies of the former Czechoslovakia. Although all covert equipment was thought to have been destroyed, some devices have miraculously escaped demolition.
 
Names
Although most spy radio equipment has been given a model number and/or a codename, some of the covert equipment of the former Czechoslovakia has so far been unidentified. For this reason we have 'invented' codenames for some of the equipment, often based on the primary target for which the device was used.
 
Users
Apart from the StB, the radio sets were also used by certain departments of the Czechoslovakian Ministry of Internal Affairs, such as Správa 1 - Rozviedka 1 (department 1 - espionage) and Správa 2 - Kontrarozviedka (counter-espionage). Most radio sets and related equipment were developed and built at Správa 6 - Spojovacia Technika 1 (communication technology).

As it is often difficult to determine whether the equipment was deployed by the StB, the ZS GŠ or Správa 1 (the actual Secret Intelligence Agency), we will commonly refer to all of them here as StB, although we are aware of the fact that this might actually be incorrect in some cases.
 
  1. In this context Správa refers to a Department of the Czechoslovakian Government.

Known Czechoslovakian equipment
  1. This name is not correct, but is suggested by us, as the device does not have a project name or number. It will be used as a nickname until the true identity of this device is discovered.

Known project numbers
Most devices that were developed by Správa 6, were given a project number starting with 'TI'. The table below shows the currently known numbers as found on the equipment in our collection as well as on the Wireless for the Warrior website [2].
