Equipment Description

Regulations require that all equipment be powered while the vessel is underway.
SSB Radiotelephone
For ship-ship and ship-station radio communications in the MF/HF band (1.6 to 26.175
MHz), the main communications modes are;
• Voice communications (J3E) via the handset
• DSC communications (J2B) by the MF/HF
• Telex communications by the NBDP terminal (J2B)
DSC
DSC function is incorporated in SSB Radiotelephone. Below are its DSC main func-
tions.
• Distress alert: Transmit the distress alert via the SSB Radiotelephone.
• Watches DSC distress and safety frequencies. The MF/HF DSC receives distress
alert from vessel in distress and all ships message (safety and urgent message)
from ship or coast station.
• All Ships Call: For urgent situation on own ship (for example, request for medical
assistance).
• Individual Call: Place a call to a specific ship or coast station.
NBDP terminal unit
The NBDP terminal unit provides Telex communications with coast station over the
MF/HF band via the SSB radiotelephone. Furthermore, it can receive MSI (Maritime
Safety Information) messages via the SSB radiotelephone (Scan reception).
Note: Note: NBDP terminal unit is not incorporated in the dual Inmarsat C type radio
rack console.
Inmarsat-C Mobile Earth Station
Provides distress and general telex communications for mobile and fixed terrestrial
subscribers in the Inmarsat-C communications network. Telex messages are pro-
cessed by what is known as store-and-forward telex. A telex message transmitted by
you arrives at a coast station where it is stored temporarily and then delivered to the
subscriber specified. (Full duplex communications are not possible.)
