Narrative:

There is a problem with backup frequencys at san juan cerap. There was a stuck microphone on frequency 118.15. All sectors at san juan cerap were open and there was not a backup frequency available to use for the sector. The only backup frequency that san juan has is 124.22 but this frequency is unidirectional and can only be used safely on 1 out of the 4 sectors of the center. This poses a serious safety risk to the flying public; because the controller is left with no out in an event that a correction needs to be made or if an aircraft declares an emergency.
