I didn't think of these cases - they make sense.
I have added an option to set the bandwidth in the I/O configuration

But honestly I think it shouldn't make a difference and the code

Hi,
And as an addition, when trying to adjust the gain, I get these messages on
the console output:
Invalid LNA gain requested: 3.48, setting to LNA_MAX (6dB)
Probably gqrx or gr-osmosdr treats the gain as a continuous value even
though on the LMS it's not, there is only a few discrete
Hi,
I played a bit more, and I found that checking the iq balance option makes
things worse, not better. Maybe the real huge center DC peak is too much?
The blind IQ estimation doesn't always works, there is no magic solution.
One of the case where it fails is if you're tuned to the center
Probably gqrx or gr-osmosdr treats the gain as a continuous value even though
on the LMS it's not, there is only a few discrete value.
They should be harmless warnings.
Yep, just wanted to mention it

The hackrf module for example has a special value of 0.0 for the
set_bandwidth call that basically mean auto-set.
When you change the sample_rate it goes to automatic unless you
manually set a specific bandwidth.
