Hello,Was just wondering if anyone else has this same situation, where Comm 1 VHF1 works fine, but after about 10 min into a flight it no longer works. Freq selection is somehow disabled-active or standby. Knobs rotate, but nothing else. Going to VHF2 works ok. I am using FSX win7 and latest build. I also notice it maybe where after I change views in virtual cockpit where it stops working. Any help is appreciated. The other thing is I keep getting ILS untunnable no matter what airport I fly into. I have latest navdach and am following procedures...thanks,Steve
