SpyVerter R2 for Airspy

Model: IM150321001

Availability: In stock

The new high performance SpyVerter, extends the reception range down to DC for a gapless DC – 1.8GHz coverage with a superb 10MHz instantaneous view.


Product Description


SpyVerter R2 builds on top of the successful SpyVerter architecture and improves some of the key points of high performance HF reception. We designed the SpyVerter R2 to extend the coverage of the Airspy receiver series to the HF down to virtually DC with world class dynamic range, frequency stability and sensitivity to rival with high end analog designs at a very affordable price. You have no excuse to use low performance receivers that require more filtering than your entire shack, killing the signals of interest along the way!

The architecture is still based on our switched double balanced mixer that moves the entire HF spectrum to the VHF band between 120 MHz and 180 MHz. We replaced the LO generator with a programmable, low phase noise PLL with 0.5 PPM VCTCXO. The Voltage control of this VCTCXO allows fine calibration of the operating frequency at the factory.

The embedded microcontroller provides both the programming of the PLL (Si5351C) and the voltage control via its embedded DAC. Once the DAC is settled and the PLL is programmed, the microcontroller enters a deep sleep mode to eliminate any interference.

We also added a 10MHz reference input clock for professional usages where phase coherency is required.

When used with an Airspy receiver, the SpyVerter R2 can be powered from the integrated Bias-Tee, and only uses ~10mA of current (versus 47mA in the old design). This improves battery operation dramatically!

An extra USB power supply input is provided for compatibility with receivers like RTL-SDR.

Customer Reviews

As good as expected Review by Cédric Beuzit
Overall Rating
I just set 4 stars because I got to adjust a little bit the USB connector with the iron pen, but overall, great device (probably the best available upverter available currently) a great reseller (Posted on 6/8/2017)
Very nice - especially considering the price! Review by Benjamin
Really liking my Spyverter. Frequency accuracy is right-on. -0.05 PPM was required to be dead-on with WWV on 20 MHz. I don't notice any long-term drift once the unit is warmed up. That warm up takes a few minutes, maybe less. Performance seems quite good. I did some A/B comparisons against a Ham-it-up converter and a homebrew upconverter. The SpyVerter was a clear winner in both cases, especially on lack of drift and frequency accuracy.

For the price, you can't go wrong. (Posted on 11/24/2015)
