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 R860 and a high quality Oversampling 12bit ADC and state of the art DSP.

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.
