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.

Works as advertised!

There was a bit of a steeper learning curve for me to get it to work with the RTL-SDR dongle but I figured it out and.., it works great. I will likely be purchasing at least one more as soon as my budget allows.

5 star service and product line

I really enjoy buying from ITEAD. Excellent service in all respects.

Richard Baker

This was a present and as yet not wired it up. Quite impressed with service and quality of item. I would suggest that rthe aerial in connector be marked on the case for those who are not familiar with these products.
Thanks for you tech/.

Not what I expected

I should have done more research. I thought that the Spyverter would add the missing 6-meter band to my Airspy Discover HF+. Apparently not... So I am still using an RTL SDR for 6 meters. I'll donate the Spyverter to a friend's ham club... I thought the Spyverter was a good buy at the sale price.

HF Airspy Mini + Spyverter + Random Long Wire

I wrote lots about the spyverter with the airspy mini to try and give a realistic experience containing logical tests and real life use experiences. Please take a looky here if you want to know more:

Good upconverter

Fast delivery. Upconverter works very well with Airspy R2 to provide HF frequency reception.

Purchased Airspy Discovery

after reading the reviews of the Airspy Discovery, I decided to use it instead of Spyverter.
now i have a Brand New Spyverter that i shall not be using. I wonder if i can return it for a refund?

Euicheol Jung
quick and works well

It was delivered to Korea quickly. And Works very well.


Cane quicly, works perfectly


It's all ok
