Nope, the UHF option wont work..i just started over an AAR mission i've found on the forum. I set via the mission builder the correct freq for the tanker. Then i followed and doubled checked the pre AAR check list. I am doing everything right in my prospective still no response from the tanker. I just don't get it. So i ended up practicing the AAR just by maneuvering under the tanker...:S
