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
