Hi Tao, I don't know anything about the kernel wireless drivers. But I do know something about RF communications, and based on that I would say "probably not". I would be extremely surprised if it were possible to see frames transmitted on channel 2 when the radio is tuned to channel 1. Traffic on channel 2 could interfere with and corrupt traffic on channel 1, but that doesn't mean you can successfully decode the frames. Cheers, Henry
