What is a potential danger of automatic transceiver switching during a DSC call?

The concern regarding automatic transceiver switching during a DSC (Digital Selective Calling) call primarily revolves around the potential for the transceiver to be switched out of the designated marine bands or for the frequency to not match the required operational frequencies. In maritime communications, using the correct frequency and being within the designated marine bands is crucial for ensuring that distress messages and other safety communications can be successfully transmitted and received by other vessels and shore stations.

If the transceiver switches to a frequency that is not aligned with marine communication protocols, it could result in a failure to communicate distress or emergency situations effectively. This would not only compromise the vessel's safety but could also endanger other vessels relying on proper communication to coordinate their responses. Thus, the correct functioning of the DSC system, which includes maintaining proper frequencies and bands, is vital to marine safety operations.
