    Airspy HF+ Discovery SDR

    0 out of 5

    Building on the field-proven Airspy HF+ architecture, we designed the Most Refined HF/VHF SDR with world class performance in the smallest form factor.


    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. Check the download page.
