VHF DSC alerting may be the sole means of Distress alerting.
HF or MF DSC may satisfy the equipment requirement.
HF SSB with 2182 kHz automatic alarm generator may satisfy the equipment requirement.
7R-5A2:

7R-5A3:
All passenger vessels must have what additional equipment?
Aircraft Transceiver with 121.5 MHz
Inmarsat-B terminal
Inmarsat-C terminal
MF-HF SSB Transceiver
7R-5A4:
Within a single sea area, what is the primary reason GMDSS imposes carriage requirements for different radio subsystems?
Each subsystem has a specific purpose and capabilities that generally cannot be duplicated by other subsystems.
Redundancy in duplicating all operational functions in the event of a system failure.
Different radio systems may be used by the various authorities.
The ability to communicate in all modes with any of the shore stations.
7R-5A5:
If operating within Ocean Area A1, and outside of NAVTEX coverage, a GMDSS-equipped vessel must carry?
Equipment capable of reception of Maritime Safety Information by the Inmarsat enhanced group call system, or HF NBDP.

Equipment capable of maintaining a continuous DSC watch on 2187.5 kHz.
7R-5A6:
What is the equipment carriage requirement for survival craft under GMDSS?
All of these
At least three approved two-way VHF radiotelephones on every passenger ship and cargo ships of 500 gross tons and upwards.
At least two approved two-way VHF radiotelephones on every cargo ship between 300-500 gross tons.
At least one radar transponder must be carried on every cargo ship of 300-500 gross tons and two transponders (one for each side) of every passenger ship and every cargo ship of 500 gross tons and upward.
