Hi wireless,

I am trying to get spectral scan working on the AR9462 in my acer c720.

As per: 
http://freebsd.1045724.x6.nabble.com/spectral-scan-now-works-on-ar93xx-and-later-chips-td6057123.html

I built a kernel with:
     options ATH_ENABLE_RADIOTAP_VENDOR_EXT
         options ATH_DIAGAPI

Based on:
http://freebsd-wireless.freebsd.narkive.com/94wkUBBj/howto-tinkering-with-spectral-scan
and discussions with Adrian on irc I built and ran:
        tools/tools/ath/athspectral
        and
        https://github.com/erikarn/ath_radar_stuff

        # sysctl dev.ath.0.monpass=0xff
        # athspectral -i wlan0 get
        # athspectral -i wlan0 start
        # fft_eval ar9280 if wlan0 

Which gives ony gives me output like:

I am expecting output similar to:
