Hi Guys,

Great product and tutorial spot on.  It is a wonderful plane, one of my favorites to date, really puts the flying aspect back in the game.  However I am a problem when I start from cold and dark, and get all the engines going and radios on. I go to change the radio frequencies (both com and nav) and they are stuck I click the adjust buttons and all I hear is clicking, also atc goes out.  The weirdest thing is when I tune ground or the tower the com radios adjust themselves to that frequency, but I can't hear or communicate. Is there something in the startup procedures I am doing wrong? Thanks again and what a great airplane as well as tutorial.

I had to asign a key to the master avionics. I have the same problem but after a toggle of the master avionics key it all works ok.
