HF-9500M Airborne HF Radio System

The future of high frequency (HF)

Step into the future of tactical and mission-critical communication with the
HF-9500M, a next-generation radio system purpose-built for 2027 and beyond.
Engineered with multidomain operability and future-ready technology, the system
integrates cutting-edge advancements that deliver unmatched performance,
reliability and adaptability in rapidly evolving environments.

A complete nose-to-tail solution, the HF-9500M has a modern antenna coupler
line-replaceable unit (LRU) that tunes wire, shunt and probe antennas, a radio
control LRU to provide alternative means of operation and proper mounting LRUs
to secure the system to the aircraft platform.

The HF-9500M supports data transmission up to 48 kHz bandwidth, meeting
MIL-STD-188-110D standards, and includes a 39-tone waveform suite to provide
robust support for 2G and 3G Automatic Link Establishment (ALE), Fast Link Setup
(FLSU) and 4G ALE protocols. The system also incorporates ARINC 714 selective
calling (SELCAL) functionality, reducing crew workload, minimizing distractions
and enhancing the safety of flight.
