Airspy HF+ Discovery

The Airspy HF+ Discovery sets a new standard in terms of reception performance with extra pre-selectors for all the supported bands and a New DSP Core to optimize the gain distribution and the filtering parameters in real-time and dig deeper in the noise.

The signal path includes very high dynamic range data converters along with high performance passive mixers with an excellent Polyphase Harmonic Rejection structure. The included band-tracking pre-selectors eliminate unwanted interference and preserve the dynamic range of the receiver. With its world class strong signal handling capability and incredibly Low Noise, the HF+ Discovery is the ideal companion for All your High Performance Receive Scenarios.

Both the architecture and level of integration achieved in this design allow us to bring top performance reception at a very affordable price. All the major SDR software is supported.

Unrivalled Noise Reduction Processing

We spent a lot of time understanding RF noise, its structure, and how it interacts with legitimate signals. Today, we have one of the most flexible and acoustically pleasant noise reduction algorithms of the market. The applications range from high-fidelity hiss removal for Broadcast FM signals, to unburying weak SSB signals from the noise floor. Our algorithm doesn’t kill the highs to give you a false impression of loudness, yet it doesn’t have the typical high tone artefacts that plague popular noise reduction algorithms like LMS and Spectral Subtraction.

Here’s a very weak SSB signal in the 40m band, with and without our Digital Noise Reduction. Check by yourself!
