The CNHF1 radio

The original KNL radio is rack mountable and requires an included HF antenna (powered by a transformer), a cellular antenna, and a GPS antenna for location tracking. We’ve built our radio to serve a number of use cases, all while being simple, secure, and reliable to operate.

Software defined radio

The CNHF1 is a software defined radio, which makes remote configurations and updates possible. Our software CNHF waveform has cutting-edge features such as cognitive spectrum usage and wide Band ALE with thousands of simultaneously listened calling channels.

HF for Data Communications

Our R&D has greatly improved the speed and reliability of HF for data communications, giving each radio a two-way connection range of up to 10,000 kilometres.

Global access

Each radio can act both as a base station (when in cellular range), and as an endpoint (when out at sea). The result is unmatched reliability and global access.
