Just dump the NF calibration results (sysctl dev.ath.X.hal.debug=3D0x8) and crank it up to say, 2 to 5 seconds (sysctl hw.ath.longcal=3D5). Let's see what the NF results are like. I have a nasty feeling that the AR9280 series NICs report some rather high NF values. The values themselves aren't actually raw NF dBm, they're just a dB value - but the fact that it's so high is likely a symptom of the overall problem (which is likely that the signal levels are all configured wrong when faced with interference.)
