Re: Low noise floor
David J Taylor
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?

For frequency calibration see:
I would try with SDR# in the first instance.
You did cold-boot the devices after updating?
You did use the correct firmware for the two devices (BB or CD variants)?
