1.1 A brief history of Maritime VHF radio
Today, VHF radio is one of the most important tools for safe navigation at sea. However, this has not always been the case. In the past, radio communication was carried out using Morse code, which required specialized training. This made communication difficult and largely inaccessible to ordinary seafarers.
Over time, the need for simpler and faster communication became increasingly important — especially in emergency situations. During the 1950s, VHF (Very High Frequency) radio was therefore introduced into the maritime sector. This made it possible to communicate directly with other vessels and coast radio stations using voice communication.
Why VHF became so important
VHF made radio communication:
- easier to use
- faster and more effective in emergency situations
- available to everyone on board
This represented a major improvement in maritime safety.
VHF Today
Today, VHF radio is considered standard equipment on most recreational vessels and is used for:
- call for assistance (Mayday)
- report urgency situations (Pan Pan)
- receive important information from coast radio stations
- communicate with other vessels
Modern VHF radios are easy to operate and often include:
- a distress button (DSC)
- built-in GPS
- a clear display
Therefore, VHF radio remains the most important communication tool at sea.
