Figure10.9.0 - Interfacing to VHF Radio
10.9.1 DSC Distress Call
During a Distress situation, a vessel that is equipped with a DSC VHF and connected to a GPS, has the capability to transmit a DSC Distress Call with GPS Position.
When the Standard Horizon VHF receives a DSC Distress Call, DSC/Position information of the vessel in Distress is transferred to the GPS chartplotter. The GPS chartplotter Logs the Distress call into the DSC DISTRESS LOG and also prompts the user to see the location of the Vessel in Distress and also allows for easy navigation to the vessel.
10.9.2 Position Request
STANDARD HORIZON VHF radios can transmit a DSC call to other equipped Vessels with a DSC VHF or request this radio transmit the GPS position. When this position is received the STANDARD HORIZON VHF radio sends the information to the GPS chartplotter which displays the GPS position of the vessel on the Chart page. This is a great feature for anyone wanting to know the position of another vessel for example you buddy that is catching fish, or finding the location of a person you are cruising with.
