Web2 Answers. Normally in amateur radio when specifying a frequency you specify the nominal carrier frequency. For SSB and other suppressed-carrier transmission modes, you specify the frequency to which the BFO needs to be tuned to re-insert the suppressed carrier. For this to work, you also need to specify which sideband you are transmitting on ... WebThe process of suppressing one of the sidebands along with the carrier and transmitting a single sideband is called as Single Sideband Suppressed Carrier system or simply SSBSC. It is plotted as shown in the following figure. In the above figure, the carrier and the lower sideband are suppressed. Hence, the upper sideband is used for transmission.

WebJan 15, 2024 · 1) SSB SC is a form of amplitude modulation where only a single sideband is transmitted and 1 sideband and carrier are suppressed. 2) The advantage of SSB is bandwidth and power-saving over both conventional AM and DSB SC, i.e. DSB SC has more power consumption than SSB SC. WebPEP is equal to steady carrier power, or radiotelegraph dot or dash average power, in a properly-formed CW transmission. ... Typical average power of a SSB voice transmission, for example, is 10-20% of PEP.
