fixed Unable to communicate with wingman in P-51D Channel map instant action dogfight missions (BF-109, FW190, etc)

[RightYouAreKen]

In these 2v2 dogfight instant action missions for the Mustang on the Channel map, I think the radio isn't set up with the correct presets to communicate with your wingman.  As a result, he just flys in formation with you until he gets shot down by the enemy fighters.  It would be nice if he could be commanded to do his part.  I manually edited the missions on my old machine to make the radio work, but I found in a new fresh DCS install on my new machine the missions are broken in this regard.  I guess I'll manually fix them again, but it would be nice if they were fixed out of the box.
