 You can also use the airspy command line tools to diagnose if you are suffering from dropped samples in your airspy.  In the following console screenshot, I'm using **airspy_rx** to test receiving and recording airspy samples at 10 MHz sample rate.  In the first run, the airspy is plugged into a USB 3 hub that isn't able to deliver the full sample rate and it's dropping ~23,000 samples every second for an average of 9.9767 MSPS sample rate.

 How do you fix this?  Try plugging your airspy into each of your USB ports to see which port(s) can provide the full sample rate.  Consider purchasing a powered external USB hub.  Other users have had success with a dedicated add-in PCI card with USB interfaces.  If your computer is too slow/old, that may also be the problem.  Finally, if you can't resolve it with any of these options, reduce the sample rate from 10 MHz to a lower supported sample rate.
