Hi Janusz,
Without | grep radar as it doesn't match anything :

for 2.4Ghz
iw pnic_wlan info
Interface pnic_wlan
    ifindex 3
    wdev 0x1
    addr 20:7c:8f:7f:e1:c3
    ssid belette_lab
    type AP
    wiphy 0
    channel 6 (2437 MHz), width: 40 MHz, center1: 2447 MHz

without hostap:
 iw pnic_wlan info
Interface pnic_wlan
    ifindex 3
    wdev 0x1
    addr 20:7c:8f:7f:e1:c3
    type managed
    wiphy 0


Is there a specific patch for this to work properly?

many thanks

What show:
iw phyX info |grep radar?

I have:
radar detect widths: { 20 MHz (no HT), 20 MHz, 40 MHz }

What in your case?
Maybe you don't have patch for HT40?
Does DFS HT20 works correctly?

BR
Janusz
