There is any firmware version to extend range under 2400 mhz for hamradio usage? wifi band 14 channel is full and amateur band near is empty .... ..

This is all included in the Atheros HAL and it's not open source (binary)...for this very purpose of operating on illegal bands. Not possible.
You could try looking at openhal, which is an open source rework of the Atheros HAL and is being integrated into MadWifi. It started life in OpenBSD but has moved over to Linux as well so it should be possible to add it to openwrt.
ok Thank's 13 cm Amateur band in region 1 (europe .ecc) start in 2300Mhz and end 2450mhz , this band for amateur radio is not illegal ... if there is any developer to contact atheros to release any info to perform this band for amateur use only ..
73 ik6ihg.
working in amateur band, with 802.11abg signal is probably illegal, because you cant transmit your callsign in any readable form. Also, 802.11abg spectrum is much wider than any other type of modulation used by ham's (SSB, CW, FM, RTTY etc), and I'am not sure, how is regulated 10-40Mhz wide abuse of ham resources.
Anyway, access point at 2312-2450Mhz (madwifi allow 2312-2732MHz), with TX power for example 50W, is interesting. Dont be surprised, when birds start falling from sky above you.

Couldn't you just make it your SSID?

hmm, this is not a bad idea at all...
Many 3rd party firmwares support extended frequency ranges already and because packet radio on lower bands is obsolet and mostly dead anyway, then it will make cheap and usable alternative for ham's.

Not much info but its a place to start looking
ok thank's , yes amateur call is located in SSID beacon and in italy experiment in wifi band for hamradio (20mhz large) is legal but very too much signal in wifi band is full !! .. now i have seen in dd-wrt firmware a keys for extendend range features ..
use madwifi and openhal by openwrt dd-wrt and maksat
set in wireless config option regdomain 0x49 and reboot
now you will get something like this
