Approfitto per un altro dubbio.
VHF canale 16 utilizzato per i distress.
A sua protezione i canali 15 - 17 e 75 - 76 trasmettono solo a 1 watt per evitare interferenze.

Nulla a che vedere con la protezione da interferenze del canale 16:

"Use of dedicated channels for on-board use
Channels 15 and 17 (156.750 MHz and 156.850 MHz) are reserved for on-board communications. They are restricted to low power to assist in ensuring that the use of these channels does not cause interference with the ships’ own on-board communications use. These allocations are in addition to a number of UHF frequencies that are also identified for on-board ship use, although this UHF allocation is via a footnote to Article 5 (i.e. are not reflected in RR Appendix 18) and to some extent subject to national arrangement and agreement but in conformance with Recommendation ITU R M.1174 series."
