Nope, I just found it strange and never heard it before on channel 16 till arriving near US waters. I'm used to calling and monitoring ch16 unless required to
monitor additional channels and haven't heard stations stating that they're using channel 16 before. I try to use the VHF by the book, as per the quoted extract above. Nowhere does it state to use the calling channel as part of the initial call. Perhaps it should, but it doesn't.
Obviously certain areas have specific requirements, as per below. Note the last paragraph specifically asks vessels to use channel 10 to discuss passing arrangements etc.
Perhaps the book should be rewritten to state the calling channel should be stated when calling channels other than ch16, or perhaps it should be rewritten to state the callers channel in all calls. Either way there's ambiguity that should be clarified for all users. As it currently reads, stating the channel when on ch16 isn't recommended.
Darwin VTS maintains a continuous listening watch on channels 16 (Distress,
Safety and Calling) and 10 (primary port operations working channel) - 24 hours a day, 7 days a week.
All vessels required to report to Darwin VTS in accordance with section 3.3 above shall, at all times, maintain a listening watch on channels 16 and 10.
Additionally, all other vessels operating within the port limits shall maintain a listening watch on channel 10 whilst underway or at
anchor.
