HF voice broadcasts may be terminated if longer than the available broadcast period. This will most likely occur during the hurricane season when supplementary advisories are broadcast in addition to the routine forecasts. Carrier frequencies are shown.  HF voice broadcasts use a synthesized voice "Iron Mike" and use USB mode. ITU channel numbers as follows: 4426 kHz (#424), 6501 kHz (#601), 8764 kHz (#816), 13089 kHz (#1205), 17314 kHz (#1625). Note that stations share common frequencies.
