If you have an AR9160 or later, the radar detection FFT enable bit is set, so for long chirp looking pulses that match the radar detect thresholds, you should see larger PHY error frames - those have radar FFT data. It's kind of, but not quite, spectral scan - which is a feature starting with the

Alex, I'm really new in the ath9k code. May you give at least soure-code-related key words about that? What should I look for in the code to get raw FFT? Then, what may you point a reference about what procedure should be performed in mathlab to decoded it? thanks On 30 May 2012 07:25, Alex

Hi, It's easy to get raw FFT data from the card, but then some cryptoanalytic work should be done in MathLab. Actualy I'm busy (lazy) man... will wait for open information which Adrian promised. :) I beleave the open source community can implement these features better than MicroTik did it. Best
