channels are used in its territorial waters. 14
*2 The output power of channels 75 and 76 are limited to
15
low power (1 W) only. The use of these channels should
be restricted to navigation-related communications only, 16
and all precautions should be taken to avoid harmful
interference to channel 16, e.g. by means geographical
