How did radio call signs evolve?

Paging name

The Paging name is the identification of a mobile or stationary radio station in the radio operation of the authorities and organizations with security tasks (BOS). Station names in international radio traffic, on the other hand, are called call signs.

Fire brigade in Germany

Digital BOS radio

In the digital BOS radio, each end device receives a unique operational-tactical address (OPTA), which is also transmitted to all receiving devices.[14] This means that the radio call names are supplemented by a display on the radio set.


The OPTA is awarded according to a nationwide uniform scheme for police and non-police BOS and consists of 24 digits that can be filled with numbers, letters or spaces. A distinction is made between the birth OPTA and the alias OPTA. Both are identical at the beginning and contain:

  • at positions 1 and 2: federal / federal state (e.g. "BU" for "federal", "SH" for "Schleswig-Holstein")
  • at positions 3–5: authority and organization identification (e.g. "POL" for "police", "FW␣" for "fire brigade")
  • at positions 6 to 8: regional allocation (city and district) (based on the vehicle registration number)

From position 9 the birth OPTA contains a unique sequence of digits and is permanently set. The alias OPTA can be freely defined within the rules and differs depending on the type of organization. It contains:

  • at positions 9 to 13: local assignment
  • at positions 14 to 21: function assignment (e.g. vehicle type, function, task)
  • at positions 22 and 23: order code (with the same location and function)
  • at position 24: addition


Since the radio call names in digital BOS radio are partly based on the OPTA, there are usually changes to the call names compared to the analog BOS radio (for example for the non-police BOS in the Instructions for the implementation of the OPTA guideline in North Rhine-Westphalia).[15] The organization passwords of the nickname (e.g. for the fire brigade "Florian", for the German Red Cross "Rotkreuz") are not part of the OPTA and are taken from the analog 4m band nickname system.

Example of radio call name formation based on the OPTA (same local assignment):

  • Radio call name in the digital system: "Florian Erkrath 01/42/2" ("Florian Erkrath zero-one two-forty-two two")

or (according to the regulation depending on the federal state)

  • Call name in the digital system: "Florian Erkrath 01 HLF20 ​​2" ("Florian Erkrath zero-one HLF twenty two")
  • associated alias OPTA:

Example of radio call name formation based on the OPTA (changed local assignment):

  • Call name in the analog system: "Florian Sauerland 9/41/1" ("Florian Sauerland nine forty-one one")
  • Radio call name in the digital system: "Florian Bestwig 03 LF 1" ("Florian Bestwig zero-three LF one")
  • associated alias OPTA:

Analog BOS radio

In the analog BOS radio, the radio call names differ between the control center radio (4m range) and the emergency station radio (2m range).

Control center radio

The control center radio covers the entire district.

  • Call name in the analog system: "Florian Erkrath 01/42/2" ("Florian Erkrath zero-one two-forty-two two")

or (depending on the regulations of the federal state)

  • Call name in the digital system: "Florian Erkrath 01 HLF20 ​​2" ("Florian Erkrath zero-one HLF twenty two")

In the 4m area, two channels were available for the fire brigade in each district. One was the general control center channel and the second was used as a guide channel for large-scale operations or major events. The control center is not integrated in the control channel itself. In their place, the main contact person is the operations management and the operations management maintains the connection to the control center.[16]

Operation site radio

The 2m range is only used on the scene because the range is very small. The range can be extended with relay points.

  • Call name in the analog system: e.g. B. Florentine Krüssau group leader

The location identifier and function are important here, and if the function exists several times, then also the serial number z. B. Florentine Krüssau Attack Troop 1 or 2.

The location identifier can be omitted if all units on the canal belong to the same location or a direct definition is made in a deployment section.

Conversion from analog to digital BOS radio

The analog BOS radio is (largely) replaced by the new digital BOS radio. The old system will remain active until all fire brigade units have been converted to the new system. This means that the radio control centers work with two systems. It is possible to connect both systems by conference call so that fire brigades in the analog system can talk to those in the digital system and vice versa.


Since a uniform radio network for the BOS is currently only being set up in Austria, the individual organizations currently need to show relatively little consideration to one another.

Common names in organizations are:

Ambulance service

Every vehicle in the rescue service has a radio number. The first digit stands for the federal state (1 = Burgenland, 2 = Vienna, 3 = Lower Austria, 4 = Upper Austria, 5 = Styria, 6 = Tyrol, 7 = Carinthia, 8 = Salzburg, 9 = Vorarlberg) and is preceded by a point or followed by a hyphen. Then, depending on the federal state, there is a 3 to 5-digit vehicle number, which can also indicate the district office assigned to the vehicle. The individual offices are called with the place name and the control centers either with “control center”, “control center” + place name or “state control center” (Styria). (In Lower Austria, 144 Notruf NÖ is called with the code name "Leo". LEO is derived from the state patron Leopold.) In Burgenland, the LSZ Burgenland control center is called. LSZ is derived from the state security center. Similar to the NR 144. The LSZ handles all rescue and fire services. So z. B. in Salzburg called a vehicle with 208. The wagon number is 8.208, but the first digit is neglected within the federal state. In Styria, it is common to call vehicles with the name of their local or district office and the vehicle number (e.g. "Leoben 12").

Lower Austrian offices that have a 3 in the fourth position of the radio code are often offices of the Arbeiter Samariter Bund. (For example, the ASB department Pöchlarn has the radio code 3-62 / 3xx).

Example of the number identification in Upper Austria: 4.1551 (4 = federal state, 15 = district (in this case Steyr Stadt), 5 = local office, 1 = vehicle)

fire Department

While the place name is an integral part of the radio call name in the local fire brigade, the number of the respective unit is used in the disaster relief service.

The place or number is preceded by a short form of the name of the vehicle. For example, there are:

  • Tank or TLF for tank tender
  • Armor or RF for rescue vehicle
  • Setup delete or RLF for fire fighting vehicle
  • Pump, KLF or LF for small fire engines or fire trucks
  • Head, DL or "Hub" for turntable ladder or lifting platform
  • Crane or KF for crane vehicle
  • Command, KDO or KDOF for command vehicle
  • MTF for personnel carriers
  • Anton,Berta,Caesar, or 1st, 2nd, 3rd etc. for the first, second, third handheld radio

Call names in Salzburg

In Salzburg, the fire brigade radio always addresses the vehicles with the "tactical designation" and the "place name", similar to those in Styria and Burgenland. B. "Tank Elixhausen" for the tank fire engine or "Rüst St. Johann" for the rescue vehicle. If there are several vehicles of the same class in one place, they are numbered consecutively, e.g. B. "Tank 1 Saalfelden" or "Pump 2 Bischofshofen". The permanently manned radio station is the LAWZ (state alarm and warning center) with its seat at the state fire brigade association in Salzburg. In contrast to other federal states, there is no integrated control center in Salzburg.

There are also five district alarm and warning centers (BAWZ), which are activated in the event of major incidents and manned by appropriately trained dispatchers. Your radio call name is "Florian" plus the name of the district z. B. "Florian Pinzgau" for the Zell am See district. Other fixed stations in the fire stations are called with "Florian" and the respective place name. These are only manned in the event of a local emergency.

Radio call names in Burgenland

In Burgenland, the fire brigade radio always addresses the vehicles with the "tactical name" and the "place name", similar to Styria. z. B. "Tank Podersdorf" for the tank fire engine or "Rust Podersdorf" for the rescue vehicle. The permanently manned radio station is the LSZ (State Security Center) in Eisenstadt, which also handles all rescue operations. Fixed stations in the fire stations are called with "Florian" and the place name. These are only manned in the event of an emergency.

Call names in Lower Austria

Permanently manned radio stations, which are usually district alarm and warning centers (BAWZ), are designated with "Florian" and the place name, e.g. B. "Florian Baden" for the BAWZ of the Baden district. Not permanently manned stations, such as the individual fire brigades, are included fire Department plus Place name called, e.g. B. "Hainburg Fire Brigade". Mobile radio control centers are also designated with "Florian" and the number of the respective district where the control center is stationed. "Florian 14" is the mobile radio control center for the Mödling district. The state warning center (LWZ) is also addressed as "Florian Niederösterreich".

The radio call names of the individual vehicles and the handheld radios are made up of the Radio call sign and the Place names together. Another vehicle in a category is also designated with 2, 3, .... For example “Pump Schlag”, “Anton Hirtenberg” or “Tank2 Zwettl”.

Radio call names in Styria

Radio call signs in Styria are basically composed of the radio call name (tactical designation) and the name of the fire brigade. Permanently manned radio stations are with Florian + area name (the area florian stations) or Florian Styria (the state control center) called. For vehicle radios in Styria, the Vehicle type and the Fire department name used e.g. B. "RLF Stainz" or "LF-B Wetzelsdorf". A fixed station that is occupied occasionally (in a fire station) is called Fire department + place name. A handheld radio in every fire brigade has the radio call sign Operations management + place name. The radio call signs for each additional handheld radio in the fire brigade are Alpha + place name (for the first handheld radio), Berta + place name (for the second), etc.

However, these handheld radios can also be used after the fire service tactical use + place name be called. Examples for this are:

  • Operations leader + place name
  • Pilot + place name
  • Respirator + place name

Individuals are called with rank + surname, e.g. B. Fire Chief Maier

Radio call names in Tyrol

In Tyrol, fire service radio for vehicles is always that Radio call sign or. Tactical designation and the Fire department name used e.g. B. "TLF Fritzens" or "SRF Hall". If there are other vehicles of a category in a fire brigade, an additional 1, 2, 3, ... will be placed behind them. For example "LF-1 Wattens" or "TLF-2 Schwaz" A fixed station (in the fire station) is called "Florian + place name". Handheld radios come with Function + place name called, e.g. B. "Operations Management Kufstein" or "Commander Telfs".

Due to a new Tyrolean Rescue Service Act, all rescue service operators must be dispatched and alerted by the Tyrol control center. Therefore, new, cross-organizational radio call names were required, which are structured as follows:[22] RD / 14/115 where RD stands for the rescue service gGmbH, 14 describes the vehicle type (11: NEF, 12: REF, 13: RTW, 14: MZF, 15: KTW, 16: GKTW, ...) and 115 is a consecutive number . The whole number must be used in radiotelephony ("rescue fourteen-one-fifteen").

Call names in Vorarlberg

All rescue and fire service operations in Vorarlberg are handled by the rescue and fire brigade control center (RFL). Both organizations are alerted by means of digital message receivers. That is why the fire brigade centers that are called "Florian and place names" are not manned all the time, but only after the alarm has been raised. The vehicles are then called with the respective place name and tactical designation (e.g. Rankweil Tank1, or Altach LF).
