Low noise floor

Francesco Di Giovanni


I have upgraded my Airspy HF+ Dual Port and Airspy HF+  Discovery to firmware to version 3.0.7.

Since then I have an  “improbable” low noise floor.

I suspect the frequency calibration file of both devices are now corrupted.

Both devices were connected to the pc when the firmware upgrade was done.

I have reinstalled SDR# and SDR Console v3, but it seems to me nothing changes.


There is a way to recreate a new calibration file?
