Sure, but a system like that would most likely require multiple independent variables to trigger - it there is no broadcast from Kremlin, if there is no broadcast from the military command, if all the satellites are offline or if they are broadcasting an all out launch sequence, AND the buzzer is off....then trigger the system. It wouldn't be just one radio station.
