What is marine SSB?

“SSB” is short for Single SideBand radio, also known as a High Frequency (HF

High Frequency (HF

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

) radio, or in old maritime thrillers as a “shortwave.” It's a radio which broadcasts and receives on a much wider and lower range of frequencies than your VHF radio.

What is SSB boat?

Single sideband (SSB) modulation provides the advantage of using all of the available transmitter power to convey information using voice or digital means.

Is Marine SSB still used?

Despite several advances in offshore voice communications such as satphones, marine single sideband (SSB) isn't going away anytime soon. That's because SSB, unlike satphones, allows an unlimited number of people to listen to a transmission at the same time.

What does an SSB do?

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.

What is SSB equipment?

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.

Marine HF Shortwave frequencies and what to expect in activity

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.

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 are the advantages 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.

What is difference between SSB and BSF?

BSF is the biggest Force after CRPF and also takes part in internal security situations. For example it is present in naxalites belts, north east etc. SSB on the other hand is border guarding force for Nepal and Bhutan Border. The Border is relatively peaceful and the boundary clearly demarcated.

What is the difference between SSB and CB?

A CB radio does not require a license to operate. CB service operates on 40 shared channels in an AM mode or Single SideBand (SSB) mode. SSB offers less noise and greater range than AM mode and is usually found on higher end CB radios. SSB has two modes, Upper Sideband and Lower Sideband.

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.

Is SSB the same as ham radio?

Hams use the same type of SSB but on ham frequencies. The Coast Guard uses SSB, mostly on marine channels, but in an emergency they can also call out to all ham radio operators on ham frequencies.

Can a ham radio talk to a marine radio?

Some radios, such as the legacy Kenwood TS-50, need to be modified to use upper sideband on 40 meters. The FCC forbids ham sets from transmitting on marine SSB frequencies, but this is standard procedure among cruising hams. The exception to this law is when there is danger to human life.

What is HF SSB?

What is SSB (HF) Radio? 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.

What is the full form of SSB signal?

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.

Do you need a license to operate a SSB radio?

You do not need a license to use marine VHF radios, any type of EPIRB, any type of radar, GPS or LORAN receivers, depth finders, CB radio, or amateur radio (an amateur license is required). Ships that use MF/HF single side-band radio, satellite communications, or telegraphy must continue to be licensed by the FCC.

Which posts are in SSB?

Nationality of SSB Constable Recruitment 2022

Constables (Laboratory Assistant, Ayah, Cook, Washerman, Barber, Safaiwala, Water Carrier, Waiter, Tailor, Gardener and Cobbler). Constables (Driver, Veterinary, Carpenter, Plumber and Painter):

What is SSB officer?

Services Selection Board (SSB) is an organization that assesses the candidates for becoming officers into the Indian Armed Forces.

Who is head of SSB?

New Delhi, Jun 1 (PTI) IPS officer Sujoy Lal Thaosen on Wednesday took charge as the new director general (DG) of the Sashastra Seema Bal (SSB), which guards Indian frontiers with Nepal and Bhutan.

Which is better SSB SC or DSB-SC?

DSB-SC - Double SideBand Suppressed Carrier

Hence it needs two times the bandwidth of SSBSC as explained later. It has advantages of having lower power consumption but needs complex detection at the receiver side. DSBSC modulation technique is used in analogue TV systems to transmit colour information.

Is SSB better than AM?

An SSB radio transmitter suppresses the carrier and one of the redundant sidebands, and thus transmits the operator's voice in less than half the bandwidth of an AM signal, and with much more efficient use of energy.

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 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.

How do you use an SSB radio?

What is SSB voice?

Single sideband modulation, SSB is the main modulation format used for analogue voice transmission for two way radio communication on the HF portion of the radio spectrum. Its efficiency in terms of spectrum and power when compared to other modes means that for many years it has been the most effective option to use.
