Hi all, I've just updated the driver changes needed to extract radar (and later, spectral scan) frames via radiotap. I've also uploaded some code that creates a BPF interface, compiles a suitable filter to just extract PHY errors, and do basic frame decoding. It's all here: http://wiki.freebsd.org/dev/ath(4)/RadarFFT I haven't yet documented the FFT format. If you have an AR9130 or later NIC, longer radar pulses come with an FFT. I'd really appreciate some help writing some visualisation tools. If I start getting some open source visualisation tools written, I'll put some more time into getting the FFT and spectral scan code/documentation opened up. thanks! Adrian
