Hi Per,

I guess I changed to much to find the bug by looking at the diff.
My motivation was to rewrite the driver, understand what's going on inside.

I've seen that spurs at 24MHz and there are also mirror images form
FM-radio, but it did not raise my suspicion until now. I'm wordering if
I disabled a filter or something.

To get to 1.9 GHz, you need to adjust the PLL charge pump register if
the PLL doesn't lock.
