High-Performance HF SDR for Critical Communications

FlexRadio’s CL-9300 Software Defined Radio is a next-generation, 100-watt wideband HF platform engineered for state and local government, emergency management agencies, public safety organizations, coastal and maritime stations, and MARS/SHARES operators who depend on reliable long-range communications. Built on a modern, open-architecture SDR core, the CL-9300 delivers exceptional receive sensitivity, ultra-low-phase-noise performance, and proven HF resilience for both voice and data operations. With up to 10 kHz transmit bandwidth and 1.2 MHz of instantaneous receive bandwidth, the CL-9300 supports advanced wideband monitoring, NAVTEX coastal operations, and robust long-haul communication even under challenging propagation conditions.

Designed for mission continuity and rapid deployment, the CL-9300 provides independent, simultaneously operating HF receivers, enabling real-time spectrum awareness and multi-channel monitoring from a single desktop system. An intuitive user interface, powerful DSP engine, and open IP-based control architecture give agencies and commercial users the flexibility to integrate the radio into existing workflows, build automated monitoring systems, or operate the radio remotely for distributed coverage.

For organizations requiring higher power or extended-range operations, the CL-9300 serves as the foundation for FlexRadio’s CLS-9301 high-power HF systems—offering seamless upgrade paths while maintaining the same control interfaces and operational simplicity.
