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?
