The propagation has been good lately.
If I'm not mistaken:
2187.5 kHz is intended for DSC calling for distress and safety communications.
2177.0 kHz is intended for DSC calling for routine ship-ship communications.
2189.5 kHz is intended for DSC calling for routine ship-shore communications.
However very few seems to follow this, and no coast station seems to be watching DSC on 2189.5 kHz.
More oddballs to the collection.
