3.5.3 Communication
3.5.3.1 Types of communication equipment
3.5.3.1.1 Radio
There are two types of radios used by fishing vessels - VHF and
SSB. VHF stands for Very High Frequency. This band is divided
into 71 channels with a frequency range of 156.000 to 163.000 MHz.
Channel 16 is the International Distress Safety and Calling Channel.
The transmission distance of VHF is a function of antennae height
and in general, is slightly more than the distance one can see.

Radio communications over distances beyond twenty miles, will require you to use a high
frequency radio frequency referred to as Single Side Band or SSB (Figure 3-2). The
frequency range is 2 to 26 MHz. Signal quality is inferior to VHF and susceptible to slight
