A marine SSB system operates on marine radio spectrums called shortwave, medium frequency and high frequency — 2 MHz-26 MHz. This radio spectrum is shared with hundreds of other radio users including shortwave broadcasts, Ham radio, FEMA, the American Red Cross, and long-range aircraft.

SSB stands for Single Sideband. An SSB radio modulates a special type of wave during transmission, also known as short-wave radio. Short-wave radio equipment on ships is part of the Global Maritime Distress and Safety System (GMDSS) established under SOLAS, the International Convention for the Safety of Life at Sea.

To tune in an SSB signal, follow these steps:

1. Set your rig to receive SSB signals. You may have to choose LSB or USB.
2. Select the widest SSB filter.
3. Adjust the tuning dial until you hear the SSB frequency.
4. Continue to tune until the voice sounds natural.

Single sideband is the preferred mode for amateur radio voice communications on the HF bands and 50 MHz. It is also used, but to a much smaller extent at frequencies above this in the VHF and UHF bands.

With SSB, channels could be spaced (usually) only 4,000 Hz apart, while offering a speech bandwidth of nominally 300 Hz to 3,400 Hz. Amateur radio operators began serious experimentation with SSB after World War II.

SSB (Single Sideband) radio has a much greater range than a VHF (Very High Frequency) radio’s typical 35 to 50 nautical miles. Medium Frequency (MF) SSB radio has a range of around 400 nautical miles, but High Frequency (HF) will reach out for several thousand.

SSB (Single Sideband) is an obscure but very important way to communicate via radio. It is used primarily for two-way voice communication by ham radio operators, aircraft and air traffic control (ATC), ships at sea, military and spy networks. Occasionally some shortwave broadcast stations use this format.

The advantage of SSB is its narrow bandwidth and higher power efficiency than the other voice modes. The Other Options: The wide bandwidth of FM provides a higher fidelity, while the fidelity of SSB suffers with narrower bandwidth, so option ‘A’ is out.

DSB-SC stands for Double SideBand Suppressed Carrier and SSB-SC stands for Single SideBand Suppressed Carrier. Both of these are modulation techiques used in AM(Amplitude Modulated) frequency spectrum. The DSBSC modulator process is mentioned in the equations below.

Disadvantages of SSB over full carrier DSB wave

• The generation of SSB is quite complex as the suppression of one of the sidebands is difficult.
• The generation of SSB requires sharp cut off characteristics of the sideband suppression filter.
• SSB receivers require more precise tuning than DSB.

In cases of genuine emergencies, Ham frequencies can be used by people who don’t have a license. How Far on What Bands? A marine SSB system operates on marine radio spectrums called shortwave, medium frequency and high frequency — 2 MHz-26 MHz.

Answer: Because 4, 6, and 8 MHz would likely fall short on the first radio signal bounce, 12 MHz and 16 MHz would likely be your best choices

(More on that later.) As a result, most modern marine SSB transceivers — a fancy name for a combined transmitter and receiver in one black box — have nearly 700 pre-stored duplex channels (specific frequencies designated as channels for easier access). After all, what’s easier: dialing through 1,000+ frequencies or 700 channels?

Certainly not SSB radio. Get this: while 4146 is always 4146 on SSB, it’s also known as 4A, and sometimes the designator 4-1. In addition, depending on the individual radio, it’s often channel 35 or channel 77, and could also be some other channel.
