Awesome!

Hmm.. I suspect this may be because you use scan command. Scanning
uses channel list which is programmed with legacy modes a and g
(implying 20Mhz). Perhaps that's the limiting factor now. Using other
(wider) modes breaks scan from what I remember but it might be worth
checking out if it impacts fft bin sizes.
