¼ Note: DSC distress calls generated by this radio are limited to the
same range restrictions that apply to regular VHF transmissions. The
vessel sending a distress can only rely upon DSC if within range of a
GMDSS Coast Radio Station. Typical VHF range may be about 20NM,
though this varies greatly depending upon installation, antenna
type, meteorological conditions, etc.
