Airspy HF+ Discovery

A 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. 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 at a very affordable price.

Airspy R2, VHF UHF RX

The Airspy R2 for VHF and UHF offers a low-IF architecture based on Rafael Micro R820T2 and a high quality oversampling 12bit A/D converter. In oversampling mode, the Airspy R2 applies analog RF and IF filtering to the signal path and increases the resolution to up to 16-bit using software decimation.

Airspy Mini, VHF UHF RX

Very similar to the Airspy R2, but in an even smaller form factor.

  • go2signals support
  • Small, versatile
  • No external power
  • USB interface
  • No IQ imbalance
