If I load the ath_pci module with these arguments:
{{{modprobe ath_pci xchanmode=0 outdoor=1 countrycode=348}}}
and I issue this command:
{{{/usr/local/bin/wlanconfig ath0 create wlandev wifi0 wlanmode adhoc}}}
then wlanconfig shows this output:

I live in Hungary, and these channels are not correct in my country. The
right channels are:
for 5ghz mode: 5180, 5200, 5220, 5240, 5260, 5280, 5300, 5320, 5745, 5765,
5785, 5805;
The wrong channels that wlanconfig shows are working well, but the right
channels not.
I don't know the atheros card type, but lspci -vvv shows the follow:

If you need it I can search you the type of the card.
The same hardware works good (FCC channels) with Mikrotik OS.
I tried the "modprobe ath_pci" command, and it's variation
(xchanmode,outdoor). The result is the same.
How can I set the correct channel list with this driver?

Comment:
The problem you describe most probably is related to the regdomain of the
card you're using. I'd guess that the regdomain is set to 0, which makes
the HAL fall back on some pseudo world-roaming mode. You will either need
to get a card with proper regdomain setting in EEPROM, or you'll need to
change the EEPROM of your card (warning: this will void warranty and
chances are that you will render your card useless - you're totally on
your own with that procedure, don't even think of complaining if anything
goes wrong - you've been warned :)).
The summary of this ticket also mentioned an adhoc leak which isn't
detailed in the problem description. If that is still a problem, please
open a new ticket for that issue.
I'm closing this ticket for now, since the problem you see doesn't seem to
be a real bug in the driver. If you find out that it's a real bug feel
free to reopen this ticket and add further description about it. Thanks.
