Hi Sergey, > You should be a wizard to reveal hw protocol without touching hw :)

So far -The RF filter is controlled by the GPIO pins on the AR928x wifi chip via some kind of serial protocol. -The functions responsible for the filter are ath_hal_hsr_init(), called once on initialisation, ath_hal_hsr_disable() and ath_hal_hsr_enable() on channel change. There is an ath_hal_hsr_get_lock_status() that does not seem to be used. -There seems to be no filter tuning after it has been setup on channel change. Reverse engineering this unreadable MIPS assembly mess will take some time... anyone willing to help? Does it make sense to open a ticket to track the issue or is this mailing list ok?
