What is SSB in amateur radio?

Single sideband (SSB) is the most popular mode of voice transmission on the HF bands in ham radio. The mode got its name from a key difference from the older mode, AM, which is used by AM broadcast stations and was the original voice mode that hams used.

What modulation does ham radio use?

Frequency modulation, FM is used in many areas of amateur or ham radio, particular on the VHF and UHF bands as well as Ten Metres. Frequency modulation provides many advantages when used for amateur radio communications. Frequency modulation tends to be used where mobile and portable operation has been more widely used …

What is SSB radio used for?

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 the difference between SSB and FM?

Notice that FM consumes the widest band of frequencies and is variable from roughly 5 kHz to 15 kHz. (The FM bandwidth varies with the power or ‘loudness’ of the voice audio provided.) SSB utilizes only one of the double sidebands of AM and also omits the carrier frequency transmission.

What frequency range is SSB normally used?

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.

What are the RTTY frequencies?

In the USA, RTTY is permitted between 7000 and 7150, although most US activity is between 7080 and 7100. DX activity is often found between 7020 and 7040. In view of the restrictions of the band, what activity there is can be found between frequencies of 10.110 and 10.150 MHz.

What frequencies does ham radio use?

As for ham radio, the FCC has allocated a specific set of frequencies that start at the AM radio band at 1.6 MHz and end at 1240 MHz. This range includes two radio frequency bands, Very High Frequency (VHF), and Ultra HIgh Frequency (UHF), each of which has its pros and cons.

What is the range of SSB radio?

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.

Do I need an SSB?

Without getting into the gruesome technical detail…the answer for most boaters is: Probably Not. If you are planning to cruise full time or sail offshore making blue water passages, then an SSB can be a VERY useful and powerful tool. But if you’re a casual coastal sailor, you will have little use for one.
