ES128 to/from VHF DSC via NMEA

[Chuck - Raymarine - Moderator]

Bill,

Outside of a distress call, DSC position reports must be polled for. Your VHF radio will be directed to send a position polling request to another vessel/station whose MMSI is known to you. The receiving vessel/station's VHF radio will then alert and provide the operator with an option to accept or reject the DSC position polling request. If accepted, the polled vessel/station's VHF radio will then transmit the its coordinates to the polling vessel/station's VHF radio. It is recommended that your review the corresponding portion of your third party VHF radio owner's manual for detailed instructions.
