I’ve just completed reviewing the new Airspy SDR receiver and can tell you that it’s a very good little receiver that I’m sure will prove very popular. You can see full details in the next Radio User magazine.
Coverage is 24MHz to 1800MHz with no gaps and a 10MHz tuning bandwidth. The Airspy also uses a 12-bit ADC to give greater dynamic range. In addition to being a very competent receiver, there’s a SpyVerter on the way that will extend coverage down to the HF bands.
Although the Airspy demands a lot of USB bandwidth to run at 10MSPS, it can also be run at 2.5MSPS on older PCs but with slightly reduced S:N radio.
The following recording shows the difference by alternating between 10 seconds at 10MSPS followed by 10 seconds at 2.5MSPS.
