Sailing on the huge ocean is interesting, but it is also risky since you are separated from other people. Thus, you need a device that can help you keep up with weather forecasts and contact emergency channels as well.
This is why every sailor needs an SSB radio. It has a long history, which starts from a communication service after the second World War to a necessary transmission gadget nowadays.
We have written this post to explain “what is SSB Radio?” and how it works. Some product reviews and safety tips are also included.
Everything You Should Know About SSB Radio
An SSB radio stands for single side band radio, which helps boats in a wide distance range (can be up to 4,000 miles) communicate, receive weather information, emails, and play music as well.
The SSB radio is also called marine single side band radio, which is an advanced version of the AM radio system.
From the beginning, the information transmitted by AM radio systems was easily obtained by other channels or frequencies, which caused serious problems and chaos. Hence, the SSB radio was made to become an effective solution to this problem.
If you are looking for a way to install a single sideband radio, you should know about these components.
1. Radio head unit
It is the display unit with a screen, a control keypad, big rotary switches, and a standard microphone.
2. SSB Transceiver
This is the most important part of the marine single sideband radio; it includes all the main electronics. It is also in charge of reception and transmission on all marine channels.
3. Antenna Tuner
For this component, you can choose between an automatic and manual antenna tuning unit. However, it’s better to get the automatic one since it is easier to work on. It connects the antenna with the SSB radio’s output.
The most popular way to establish an antenna is using a backstay. The minimum length of the antenna should be 7.5 meters.
Although you might have your antenna and the radio head unit setup all done, the signal transfer will still be weak if you forget about the ground plane. It works as a springboard to boost your signal from the antenna.
The best choice for the grounding is using sintered bronze plates, also known as the dynaplate outside of your hull. A steel hull is also commonly used, but it often causes electrolysis issues, so, be careful. A solid grounding can strongly affect your transmission.
How to Use a Single Side Band Marine Radio?
How does it work?
Marine radios contain VHF (short for Very High Frequency) and SW (Short Wave) Frequency. The limits of the VHF are around 25 nautical miles (about 46.3 km), while the Short Wave can cover a wider range.
The marine single side band radio’s frequency range covers 3MHz to 30 MHz. The signals from the SSB radio reflect off the Earth’s ionosphere, then go back to the ground thousands of miles away. The skywave reflection depends on your radio type.
How to listen to your SSB radio?
You can follow our steps:
- Step 1: Set the head unit to receive the signals
- Step 2: Select the SSB filter (the wildest range filter)
- Step 3: Slowly tune the rotary switch until you can hear a natural and clear voice.
