Hi,

So the payload length will be based on HT20 vs HT40, but also the
spectral scan FFT config. You can specify how many samples to take
each time and whether to gather them "short" or "not short" time
interval.

So fiddle around with the number of samples in the FFT config and
you'll see different sized payloads.

Since Felix has just posted the spectral scan FFT format, we may as
well post the radar FFT format. :)
