Radio question

[sputnik monroe 102]

I'm making a mission where you can call for an airstrike via 0-0-1. The thing is I'd like that option hidden from the player until they destroy an Antiaircraft site. So my question is simply, how do you hide radio alpha, bravo etc until a later point in the mission?

Type of returned value:

Description:

   Set radio message (0, 0, map radio) to given text. Use "NULL" to disable radio slot.

Example:

0 setRadioMsg "null" to hide

0 setRadioMsg "your text" in a trigger or script to make it visible.
