This is one of the handiest features I know for FSX, the ability to just hit cc12050 to set your Comm2 to frequency 120.50. No clicking the frequency
knobs or messing around changing your view or pulling up 2D panels to click and hold the knobs. Just hitting the keys fast and easy and voila, the
frequencies are set.

But, this feature is only active when you have started an actual FSPassengers flight.

Is there any way to make this feature remain active when not in a started FSP flight?

I am quite certain this cannot be done. If it can be done, I don't know of anyone who has accomplished it.
