Is SSB a VHF?

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.

What is the difference between VHF and SSB?

While nearly all boats carry a VHF, its maximum range isn't more than about 25 miles. This is because VHF radio waves travel in a straight line or line of sight. In contrast, waves from marine single-sideband (SSB) radios travel up to the F layer of the ionosphere, 75 to about 250 miles above the Earth.

What frequencies are SSB?

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.

What is marine SSB?

ByMI News Network February 23, 2019. SSB radio is used by boats or yachts for communication at sea. The full-form of SSB radio is Single Side Band radio. SSB radios are an essential feature when it comes to important marine radio channels.

What is an SSB antenna?

GAM Split-Lead SSB Antenna

On sailboats, the normal practice is to insert insulators in the backstay to create whats correctly referred to as a random-length end-fed wire antenna (as opposed to a long-wire antenna, which would be a wire antenna that is multiple wavelengths long).

Understanding Single Sideband

What is SSB on a radio?

In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves. A refinement of amplitude modulation, it uses transmitter power and bandwidth more efficiently.

How far can a SSB radio transmit?

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.

Is SSB an HF?

High Frequency (HF) radio, often referred to in the UK and USA by the initials “SSB” (which stand for Single-Side-Band) is a type of radio that operates on specific short-wave (HF) frequencies reserved for marine use and provides voice communication over long distances.

Who uses SSB?

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.

How do I get SSB radio?

Is SSB FM or AM?

What is SSB? Single sideband is a special form of amplitude modulation (AM). What's so 'special' about it? Besides just encoding voice information with variations in signal amplitude, or power, SSB consumes a little less than half the bandwidth of a full “double band” AM signal.

Why is SSB not used for broadcasting?

When carrier is shifted to bandpass, this one sided bandwidth becomes 9 MHz. This is nearly ten times as large as the total bandwidth occupied by all the channels of the AM radio. Use of SSB modulation would cut this in half but SSB is not used for video signals because of the complexity of the SSB receivers.

What is SSB and CW?

SSB is a mode. AM is a mode. FM is a mode. CW (Continuous Waveform aka Morse Code) is a mode. RTTY (radio teletype) is a mode.

Is SSB CB legal in the UK?

CB is now legal in UK but users must abide by the regulations for frequencies, mode, power and equipment. Since 2006 CB Radio, using FM mode was legal without a licence being required. This Licence "Exemption" was increased to include use of AM and DSB/SSB signals in 2014.

Do I need SSB?

If you plan to do any offshore cruising, I highly recommend having a marine SSB radio. This will allow you to keep in contact with other sailors traveling outside your VHF range as well as various nets, which may be able to render assistance in case of a problem or emergency.

How do you use marines in SSB?

“To use marine SSB, your ship needs a marine SSB call sign from the Federal Communication Commission (FCC), called a station license, which is good for 10 years, and also includes your International Maritime Mobile Service Identity number.

What is the difference between SSB and FM?

Firstly, FM is a constant-envelope modulation, meaning the amplitude is constant. SSB, being a kind of amplitude modulation, obviously does not have a constant amplitude. Consequently, FM can employ a non-linear amplifier which is more power efficient, and thus has a longer battery life in mobile operation.

What is the main benefit of SSB?

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.

Which is better DSB or SSB?

We can see that the SSB transmission does not suffer from the effect of power fading induced by fiber dispersion, while the DSB has a high tolerance to power fading, due to the low frequency of RF carrier [8] . The DSB has a better performance than SSB under short distance because of double sideband. ...

Are SSB radios still used?

As satellite communication equipment becomes more reasonably priced, more reliable, and more compact, we often hear sailors raise the question, Are single-sideband radios even relevant anymore? As Lanier points out, the question is easy to answer: Yes, absolutely.

What is HF SSB transceiver?

MF/HF RT radio is often known as SSB radio. It is a transmitting-receiving system often referred to as a Transceiver (Tx/Rx), which allows the operator to either transmit or receive information by voice. MF/HF radios use SSB modulation for voice communication.

What does SSB mean on a CB?

CB radios in the United States can transmit AM (amplitude modulation) signals, or SSB (single sideband, with suppressed carrier) signals. An AM signal consists of two redundant sideband signals that each contain the operator's voice, along with a so-called carrier signal between them.

What is SSB and DSB?

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.

What is the main disadvantage of SSB?

Disadvantages of SSB-SC Modulation

The SSB transmitter and receiver need to have an excellent frequency stability . A slight change in frequency will hamper the quality of transmitted and received signal . Therefore, SSB is not generally used for the transmission of good quality music.

What is SSB transmitter?

A single-sideband (SSB) transmitter differs from an AM transmitter in that it only transmits either the upper or lower sideband—not both. Thus, an SSB transmitter uses less bandwidth than an AM transmitter. Figure 1 shows one implementation of a SSB transmitter.
