The dependable VHF/UHF Radio for your projects

Airspy R2 sets a new level of performance in the reception of the VHF and UHF bands thanks to its low-IF architecture based on Rafael Micro R820T2 (or R860) and a high quality Oversampling 12-bit ADC and a state of the art DSP resulting in up to 16-bit resolution at narrow band channels.

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 the software decimation. The net result is Spectacular Performance!

The coverage can be extended to the HF bands via the SpyVerter up-converter companion.

The Airspy R2, like its predecessor is 100% compatible with all the existing software including the de facto scanning standard SDR#, but also a number of popular software defined radio applications such as SDR-Radio, HDSDR, GQRX and GNU Radio.
