Who uses SSB radio?
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 can I listen to SSB radio?
Tune between 7125-7300 KHz until you hear a modestly strong distorted voice. Now press the SSB key and let the SSB circuit download. Then press the Fine Tune Key (both key lights be on) and turn the tuning knob up and down until the voice becomes legible. Most likely you will be listening to a ham talk to his friends.
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.
How far can a SSB radio transmit?
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.31 мая 2008 г.
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 still used?
Although this was often difficult for the amateur radio operators of the 1950s to obtain, it is no longer a problem with today’s modern SSB transceivers, such as the SG-2000 and SG-2020. You might wonder why SSB modulation is used for some applications and AM is used for broadcasting.
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.
How does SSB radio work?
Basic concept. Radio transmitters work by mixing a radio frequency (RF) signal of a specific frequency, the carrier wave, with the audio signal to be broadcast. … SSB takes advantage of the fact that the entire original signal is encoded in each of these “sidebands”.
How do I tune my antenna?
CB Antenna Tuning Instructions
- The first thing you need to do is find a suitable location to park your vehicle. …
- The next step is to hook up the SWR meter. …
- Now you are ready to measure the SWR on a few different channels. …
- Set the switch on the SWR meter to “FWD.”
- Turn the radio to channel 1.
- Key the microphone (depress the button and hold it).
Why SSB transmission is preferred?
The advantages of single side band SSB transmission are as follows. It allows better management of the frequency spectrum. More transmission can fit into a given frequency range than would be possible with double side band DSB signals. All of the transmitted power is message power none is dissipate as carrier power.
Why is SSB better than DSB?
Whereas here, both the side bands are transmitted without the carrier, after modulating the signal. The bandwidth is twice that of message signal and power transmitted is more than that in SSB. SSB is better than DSB.

How far can a 2 meter radio transmit?
On VHF frequencies such as 2-meters, antenna height greatly influences how far one can talk. Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
