Airspy R2 sets a new level of performance in the reception of the VHF and UHF bands thanks to its low-IF architecture, high quality ADC and state of the art DSP.
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.
For a more complete list of supported software, check the download page.
- Windows Vista, 7, 8, 8.1 and 10 (For Windows XP, please contact the airspy team)

My R2 Micro USB connector very delicate and it falls out, i wish that connector would be a little deeper so the Micros USB locks in. just a slight bump and or tap the plug comes out. Now the R2 Receiver is Fantastic. been using it on 6 meters a lot.
Thank you for the interesting product (Airspy R2 + Spywerter). Now it is possible to compare them with RSPdx.
My old SDR constantly lost USB connection to my computer and kept crashing the software I was using. This SDR doesn't have that problem and the bandwidth is also much larger which is nice
Soso - Updated review
After my previuos review due of troubles with the micro USB connector and high noise level,
Itead kindly sent me a replacement of the Airspy R2.
Now the bad contacts with the micro Usb port disappeared and the noise floor is almost as the Airspy HF+ Discovery.
I also ordered the Airspy Spyverter to expand the frequency coverage.
Now I am very satisfied of the radio.
Thank you Itead for the top customer service, definitely a five star product!

The Airspy R2 arrived rather quickly from Itead. My other two Airspy receivers (Airspy HF+ and Airspy HF+ Discovery) I have bought from Astroradio in Spain but they never answered when I asked for the availability of the R2 .
The noise is higher than the other 2 Airspy HF+ receivers tuned on same frequency.
But what makes me angry is its fragile and unreliable micro USB connector!
Every time I touch the receiver 50% of time it looses the connection with the pc.
I have tried with different new cables but they can't solve the issue. Why Airspy don't adopts the USB C connector? It is not much bigger than micro USB. The R2 Mini with its male USB A connector would have been the best choice...

Thank you for your email.Everything has been ok.
I was expecting a long wait for this item but it arrived rather quickly considering. Now to wait for the R3 to appear ..... 😉
Performance is outstanding. Soldering quality not so good.
I had to buy a new unit as the old unit miniUSB port solderpoints failed.
Great product and good service
