Decoding SITOR-B transmissions from NMO Coast Guard Honolulu with various warnings to sailors such as 2 20 meter tress floating in the Coral Sea and the ship Sea Shell missing with it's last known position as 03.43.94N 105.36.41E. And the M/V Vespucci towing 10 8100 Meter long cables, some type of seismic survey.
Pretty interesting radio reading.
