Hi Scott,

Thanks for the pointer. However, this code is still using the HAL 
(calling ath_hal_radar_wait). This function is probably waiting the 
required 60s (Channel Availability Check Time, as described in ETSI EN 
301 893 v1.2.3). However, there is also the "In Service Monitoring", 
which i can't find in this source file.

Basically, I was searching for some interrupt that is generated when a 
radar is detected. It seems that the OpenHAL has such stuff however. In 
the current madwifi, it seems one can filter (ath_hal_setrxfilter) on 
HAL_RX_FILTER_PHYRADAR and check it with HAL_PHYERR_RADAR in 
ds->ds_rxstat.rs_phyerr & 0x1f (according to madwifi-old).

What would be needed is someone with a radar simulator to check all this....

Best regards,
Benoit
