About Boat Radios

Boat radios have been at the center of technology advances. They have been as significant as all other changes for commercial and pleasure boating.  As usual the big developments in electronics and software have transferred into the small boat market from commercial and military applications.  This communications revolution has affected the largest merchant ships to the smallest fishing boats.   

The days of a simple VHF radio or a 27 MHz citizen band radio are almost gone. For larger ships, boats and yachts HF/SSB shore stations have largely ceased operations in most main western countries, along with Morse. The Global Maritime Distress and Safety System (GMDSS) is now fully operational with far reaching ramifications to all boat owners. Given its capability to advance safety afloat, you would be nuts not to have a GMDSS DSC VHF radio when boating offshore 

All About GMDSS and Boat Radios 

GMDSS has transformed the maritime communications area. Many smaller boats and cruising yachts are still not plugged into the international standard distress system. There is much to know about GMDSS Communication I click the link and learn.  These radio types continue to incorporate more functionality as well as easier to use and more reliable. GMDSS has changed a lot of things with boat radios, with DSC VHF radios now almost standard on most smaller boats, and cell phones getting used is widespread if not controversial when used.

All About Boat VHF Radios 

VHF radio is by the far most common boat radio in use, for inshore and offshore communications.  There issues about Boat VHF Radio licensing.    Then there is VHF marine radio theory. Then we must consider VHF radio operation. Finally there are all the installation and troubleshooting issues that are centered around the VHF antenna. With GMDSS we then have to understand how the DSC radio works and how to operate it correctly. Always know what VHF radio channels you should be using.  Caution. A mobile phone is no substitute for boat radios, make sure you have both to be safe out on the water.

All About Boat HF/SSB Radios 

GMDSS has virtually eliminated HF/SSB voice communications with coast stations.  There is a place for HF radio when ocean voyaging. I will differentiate here between SSB marine radio, Amateur HAM radio and Marine SSB/HF radio. HF marine radio is part of the GMDSS system so when connected to GPS they also have available DSC distress calling functions. It also allows you to hook into maritime nets, email, weather fax, Navtex and so on. 

All About Boat Satellite Communications 

Marine Satcom communications are very much part of the GMDSS system. For many who have the budget this is used for data, voice communications rather than HF/SSB radio. INMARSAT is synonymous with maritime satellite communications.

All About Boat Ham Radio 

Ham radio has become a logical choice for long range communications on yachts now that GMDSS has virtually eliminated HF/SSB voice communications with coast stations.  For more on HAM radio click on the link for all useful maritime mobile frequencies and HAM net information you will ever need to go cruising.

All About Boat Cell Phones 

The smart phone has also became a major feature of boats. For around 99% of boaters who day trip, weekend boat, coastal cruise, the smart phone is used frequently. There so many great Boating Apps to use. I will say it now and again later, cell phones are not a substitute for boat radios with severe limitations.

About Radio Frequency Interference

Some of the old problems still exist and so this should help you solve some of the issues as they occur on your boat. 

PART 1 of this 3 Part Series on RFI Interference problem solving on your VHF and SSB radios along with noise on your GPS and marine electronics. Understand what causes it and how to eliminate it.

PART 2 of this 3 Part Series on problem solving HF Radio Interference. All you need to know about interference, noise and RFI on your marine electronics and communications systems.

PART 3 of this 3 Part Series on RFI Suppression and Interference problem solving on your GPS, marine electronics and SSB radios. Get rid of the noise.
