We have some Ubiquity NanoStation5. With kamikaze 8.09 we must set this in /etc/modules.d/50-madwifi:

ath_ahb countrycode=203 outdoor=1

I try upgrade to 8.09.1 and I get error

In https://dev.openwrt.org/ticket/5316 is

But this not work for me. After some searching I found this line in /lib/wifi/madwifi.sh

echo "$country" > /proc/sys/dev/$device/countrycode

So solution for me (203 is Czech republic) is not set countrycode but country:

uci set wireless.wifi0.country=203                                                                                   
uci set wireless.wifi0.outdoor=1

And

sysctl dev.wifi0.countrycode

is now show the right value.

In documentation (http://kamikaze.openwrt.org/docs/openwrt.html) is

but letter specification is not working for me, so is error in documenation?

This solution works also for me, I use a Wl-500gp v1 with Atheros CM9 and running also 8.09.1.

I set my country code (528, the Netherlands) and channel 12 en 13 became available.
Yesterday I tried to change the country code on 8.09 but it didn't worked.

Thanks for posting your findings!

how do I use uci?
in telnet?

i have found it out: /sbin/uci ;-)

works!
but why does the entries in the web-config do not apply?
