Can anyone Mod a Midland 75-822 40 Ch. Radio?

Hello World: I have brought this radio to Iraq with me and I am not picking anything up with it. I have a very large antenna that I hooked it to and still nothing.(approx. 12' tall) If anyone knows of ways I can get more channels or what frequencies I can pick up random chatter on, in the Baghdad area I would be very appreciative. Also This is an American version of this radio and I am brand new to this. It has CB ch. 1-40 and NOAA Ch. 0-9. Is there maybe some type of amplifier/repeater I can get? Thank you in advance..
