(a) (1) All flight termination system activation switches; (2) All intermediate equipment, linkages, and software; (3) Any auxiliary stations; (4) Each command transmitter and transmitting antenna; and (5) All support equipment that is critical for reliable operation, such as power, communications, and air conditioning systems. (b) (c) (d) (e) (f) (g) (1) Low transmitter power; (2) Center frequency shift; (3) Out of tolerance tone frequency; (4) Out of tolerance message timing; (5) Loss of communication between central control and transmitter site; (6) Central control commanded status and site status disagree; (7) Transmitter site fails to respond to a configuration or radiation order within a specified period of time; and (8) For a tone-based system, tone deviation and tone imbalance. (h) (i) (1) The radio frequency signal and radiated power density that each command destruct system needs to activate during flight; (2) The 12-dB power density margin required by section D417.9(d) of appendix D of this part under nominal conditions; and (3) A 6-dB power density margin under worst-case conditions. (j) (k) (1) Transmit signals that are compatible with any command destruct system's radio frequency receiving system of section D417.25 and command receiver decoder of section D417.29 of appendix D of this part; (2) Ensure that all arm and destruct commands transmitted to a flight termination system have priority over any other commands transmitted; (3) Employ an authorized radio carr
