AIRSPY SPYVERTER R2 REVIEW
The Spyverter R2 is an amazing instrument. Never has fifty dollars gone so far. After getting all of the settings dialed in, I found that it is the most quiet HF receiver I have ever used. You can lower the noise floor to a faint whisper, while still being able to receive signals at  60+dB SNR. It truly compliments the ninety nine dollar AIRSPY Mini.

AIRSPY SPYVERTER R2 HF UPCONVERTER

That is one heck of an HF monitoring station for one hundred fifty dollars and some wire. Those days of listening to a heavy static noise floor are virtually over. The performance of the Spyverter R2 upconverter speaks for itself.

AIRSPY is the king of selectivity. (adjacent frequency strong station rejection) As seen in the first part of the video, a ham radio operator is upset because the big AM station is bleeding over on to his conversation on a nearby frequency. As also seen in the video, the AIRSPY / SPYVERTER places a brick wall between what you are listening to and the stations on adjacent frequencies. There is little or no bleed-over from nearby radio traffic.

A Broadcast AM Reject / High Pass Filter is required when using AIRSPY / Spyverter with a random length wire antenna. ($17) As seen in the picture above, that is the little black box that is connected to the Spyverter. Without this filter, local AM broadcast radio stations bleed-over on to the entire HF spectrum.

CONCLUSION
Make sure that you order a SPYVERTER R2 (second edition) from airspy.us. There have been reports that certain outlets are selling Spyverter first edition, while advertising the product as Spyverter R2. The Spyverter R2 is better than the Spyverter first edition.


WARNING
Do not install your Spyverter backwards. I have read some reports that suggest installing the Spyverter backwards will damage the device. You must install the Spyverter with the USB power connection facing the SDR radio, as seen in the picture below.

AIRSPY SPYVERTER R2 REVIEW

PERSONAL TIPS
AIRSPY SDR radios tend to run plenty warm. With that stated, I power my Spyverter R2 with a quality USB cable that is plugged in to a USB port on the computer. My rationale being, since the AIRSPY SDR already gets plenty warm, I do not want to make it any warmer by having to supply Bias Tee voltage to the Spyverter R2 upconverter.
My AIRSPY receiver is cooled by a two inch CPU fan that also plugs in to a USB port.


WARNING
When the Spyverter R2 is being powered by it's USB input, make sure that the Bias Tee function is unchecked / disabled in the SDR radio software. I  suspect that the Spyverter could be damaged if USB and Bias Tee power were activated at the same time.
