SY-5000 is Telefunken's name for a military digital data communication system for use by the European stay-behind organizations . It was code-named Harpoon . The German and American designation was FS-5000 (Feldstation or field station ), in Dutch it was known as AZO-90 ( Automatic ZendOntvanger 1990 ).

The SY-5000 can be operated on shortwave in the frequency range 2 to 29.999 MHz in 1 kHz steps. The maximum output power of the S-5000 transmitter module is approx. 30 W PEP. The integrated antenna tuner enables end - fed long-wire antennas of different lengths to be adapted . The SR-5000 memory module controls the entire system and contains the microprocessor with the EPROM which contains the operating software, as well as other peripheral components. It is used to enter the transmission and reception frequencies as well as to store and encrypt up to 10 texts and at the same time enables the decoding and display of received texts.

It was developed by AEG-Telefunken in the early 1980s . After completion in 1985, the system was gradually ready for use until 1990/91. FS-5000 units were stationed not only in continental Europe (NATO countries and e.g. Switzerland), but also on the British Isles, which are assumed to be the contact point for governments in exile in an emergency, and in the USA.

The briefcase-sized SY-5000 consists of a maximum of seven individual units in aluminum housings, which were put together modularly. The receiver can also be operated independently with a 14.4 V nickel-cadmium battery . The components are protected against vibration, moisture, etc. The system works with fast encrypted data transmission, no longer in Morse code as was common in the past. A message with approx. 60 characters was transmitted in less than 1 s and thus made it much more difficult for the enemy radio reconnaissance to find the bearings.

The successor model is the HRM-7000 from Telefunken, introduced in 1997 , a common predecessor model is the PRM-4150 from Racal . According to official information, the stay-behind organizations were dissolved by 1992. Some of the devices were characterized obsolete modified and referred to as "FS-5000M", in Germany for example in the remote scouts the armed forces continue to be used for training purposes in particular, until it gradually replaced HRM 7000 and were finally taken out through the.
