BREAKING NEWS
The 9671 HF Radio Family is a next-generation high frequency (HF) communication solution developed to provide secure, long-range, and electronically resilient communications in modern operational environments. Operating within the 1.6–30 MHz HF band, the system leverages ionospheric propagation to enable beyond-line-of-sight communication over hundreds or even thousands of kilometers without reliance on satellite infrastructure.
Operational Purpose and Role
The primary mission of the 9671 HF Radio Family is to ensure secure and uninterrupted long-range communications at both tactical and strategic levels. In scenarios where satellite communications may be denied, degraded, or disrupted, HF systems serve as a critical alternative backbone for command and control continuity.
Typical mission profiles include:
Doctrine and Concept of Operations
Within a modern network-centric warfare doctrine, HF communication represents a resilient communication layer complementing SATCOM and V/UHF systems.
The 9671 HF system functions as:
Its 3G ALE (Third Generation Automatic Link Establishment) and Automatic Channel Selection (ACS) capabilities enable automatic selection of optimal frequencies based on ionospheric conditions, reducing operator workload and improving link reliability.
System Architecture
The 9671 HF Radio Family is built on a Software Defined Radio (SDR) architecture, allowing flexibility and future scalability. Through software updates, the system can support new waveforms, updated encryption modules, and evolving NATO standards.
Core architectural components include:
Electronic Protection and Survivability
Modern battlefields expose communication systems to jamming, interception, and electronic attack. The 9671 HF Radio Family incorporates multiple layers of protection:
In frequency hopping mode, encrypted voice and data transmission significantly reduce the probability of interception and jamming effectiveness.
Performance and Communication Process
HF performance is inherently dependent on ionospheric conditions. The 9671 system mitigates environmental variability through adaptive mechanisms and precise frequency control:
With 3G ALE, the link establishment process is automated: the system scans available frequencies, evaluates link quality, selects the optimal channel, and initiates secure communication.
Integration and Ecosystem
The system is designed for integration with military command and control systems, tactical data networks, and fixed communication infrastructures. NATO STANAG compliance ensures interoperability with allied forces.
Configurations
This modular structure allows deployment from coastal stations to blue-water naval platforms.
