Using demo and I am able to bring up ATIS by putting frequency into my com radio, but then when I try to use the hotkeys, I get no response. Is it not ctrl,shift, and 0 on the keypad after you have set the frequency into the com radio? This is on my addition of FSX.
The default hotkey bindings are the numbers in the top row, not numeric keypad.
But you can reassign hotkeys if you like to.
