History

The System is succeder of the „FS-5000M“ Tranceiver.[2] Telefunken developed HRM-7000 since 1994 and it is service at Bundeswehr since 1997.[3] The „HRM 7000 Manpack“ is specified for mobile use in combat situations. It is used in deployments abroad i.e. at KFOR. Because of its relability and lightweight it is used by the Kommando Spezialkräfte and Quick Reaction Forces / European Union Battlegroups.

Technology

The HRM-7000 system is a family of shortwave radios. The devices are designed to ensure fast connection setup worldwide and can handle both voice and data transmission. The HRM-7000 uses Automatic Link Establishment (ALE) to search for suitable connection frequencies and is therefore not susceptible to fluctuations ionospheric conditions and targeted interference.

The portable variant HRM 7000 has an output power of 30 Watt, which can be sufficient for worldwide data communication.[4] The vehicle version HRM 7400M, has an output power of 400 W thanks to the higher battery availability. Different operating modes are possible with the system. This includes encrypted data and Telephony. A connection can be established conventionally or with Automatic Link Establishment (ALE). The system automatically adjusts the transmission power in a range from 3 W to 30 W.

For a more universal and space-saving use, the antenna adapter is available separately. The terminal of the transceiver can also be operated remotely. The complete data transmission, operation and programming takes place from the PC, laptop, PDA (also wireless) via a standard interface. RACOM has had the system certified according to MIL-STD-810 E and VG 95332.
