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.

Is single sideband still used?

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.

Is SSB radio necessary?

Everything you need to know about SSB marine radio. For many who sail around the world, a short-wave radio system is a must-have on board, as an SSB marine radio system can be used for very long distances.

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.

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.

Marine HF Shortwave frequencies and what to expect in activity

What is marine SSB?

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

Whats is SSB?

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

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.

What's the difference between a ham radio and a marine radio?

Ham radio has a much wider range of frequencies, some of which overlap those in marine SSB There are also more transmission methods that can be used such as amplitude modulation and frequency modulation. Hams can also transmit using single-sideband, which is really just a modified form of AM.

Is SSB radio 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.

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.

What is the uses of SSB?

Single sideband, SSB, modulation is used in many voice applications. It is used for HF communications, but forms have been used for analogue TV broadcasting. Single sideband modulation is widely used in the HF portion, or short wave portion of the radio spectrum for two way radio communication.

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.

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.

Do ships still use HF radio?

Further, the use of HF radiotelephone has been largely replaced by HF DSC, VHF radiotelephone (and DSC) services and wider availability of Global Maritime Distress and Safety System (GMDSS) satellite systems (including EPIRBs, Inmarsat and Iridium GMDSS systems).

Do Cobra CB have SSB?

The Cobra® 148 GTL is a full featured radio with 4 watt AM and 12 watt SSB operation. Over the years, Cobra® has done a good job keeping the CB radio models that work in production.

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.

Can SSB talk to CB?

You can only communicate with other SSB CB radios when in SSB mode. (b) The FCC has issued a cease and desist order to you, and the order is still in effect." CB channels and frequencies are not assigned to any specific individual or organization.

Can I use a marine VHF radio on land?

Marine VHF radios, whether fixed or handheld, may not be used on land, period. It's the law. Once a VHF radio goes ashore, it cannot be used for marine band transmission (without a Coast Station License).

Do you need a Licence for a VHF marine radio?

Do I Need A Marine VHF Licence? Anyone who uses a Marine VHF Radio needs a licence. If you are a sailor, powerboater, kayaker, angler or even a paddleboarder, you will most certainly need a marine radio.

What are the marine SSB frequencies?

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.

How many times SSB is conducted in a year?

If you want to join IMA you can apply for it twice every year till the age of 24 years, for AFA till 23 years, NA till 22 years and for OTA till 25 years. So roughly you will have 4-6 SSB interviews with this entry if you qualify CDS written exam every time.

What is the salary of SSB?

SSB Constable Salary as per the official notification has a grade pay of Rs 2400 and basic salary is in the range of Rs. 5200-20200. Added with allowances and benefits the salary offered to constables in SSB is rewarding.

Is SSB difficult?

SSB is difficult but not impossible. If they can crack it one go, you can too. Read here tips to ace CDS SSB in your first attempt. Combined Defence Services (CDS 2019) written exam concluded on September 8, 2019, and now the candidates are eagerly waiting for the CDS written exam result.
