The mage can hijack an extant radio signal, transmitting her own words on it and replacing the original transmission.
While this spell gives the caster the ability to replace one signal with another, it doesn’t convey the skill or talent needed to fake a specific transmission. That requires Skills appropriate to the transmission, which could be Expression, Subterfuge and even Science.
The Storyteller decides what roll needs to be made to devise a convincing transmission.
