merchant-ship broadcast system (MERCAST)
A maritime shore-to-ship broadcast system in which the ocean areas are divided into primary broadcast areas each covered by a high-powered shore radio station that broadcasts simultaneously on one medium frequency (MF) and one or more high frequencies (HF) for routing messages to ocean-going ships. Note: In some instances, coast stations may repeat the messages. [From Weik '89]
