OKAY HERE'S ANOTHER FIX !!!
IN:eg for the SU-25
C:\Program Files (x86)\Eagle Dynamics\LockOn Flaming Cliffs 2\Config\Input\Aircrafts\su-25\keyboard
There is the file keyboard.lua that you are editing when you change keyboard commands in the options page in-game.
This does NOT have the Radio Commands, but you need to know this file, because you will have to check for conflicts later.
The file to change the RADIO COMMANDS is in:
C:\Program Files (x86)\Eagle Dynamics\LockOn Flaming Cliffs 2\Scripts\Input
and it's called: WingmenCommandPlane.lua
I used Notepad++ to find F1 - F12 and replace those keys to the Num1 - Num0 (F11=Space and F12-Num.)
BUT THEN: My game would not get past the "Pause/Break to start" and even though I reassigned the Pause Key in-game it still was not working.
WHAT I FOUND: The "Num." key that I had assigned in WingmenCommand.Plane.lua was conflicting with the default assignments for "Num." that the game was getting from the keyboard.lua in the above directory. I went in-game and cleared the remaining "Num." assignments.
The game runs, and I have the RADIO COMMANDS assigned where I need them for my configuration.
Super Happy About that one.
Hope this helps others who hate the F1 - F12 thing.
