NAVTEX MSI broadcasts are received using which mode?

NAVTEX uses the SITOR modulation for Maritime Safety Information transmissions, and receivers can handle two modes: SITOR-B, which provides forward error correction, and SITOR-A, which implements ARQ (automatic repeat request). Because MSI broadcasts may be received reliably in either mode depending on the equipment and conditions, the best answer is the one that recognizes both SITOR-B and ARQ as valid receiving modes. This reflects how NAVTEX can be decoded with FEC alone or with ARQ-based retransmission support to ensure data integrity.
