Quick Answer
No license is required to use SSB technology on an amateur radio, but you will need a license for commercial use. However, using an SSB transceiver on a CB radio is not allowed in the US, as it can transmit on frequencies above 4 GHz, which is outside the CB band.
SSB Technology Basics
SSB (Single Sideband) technology is a mode of transmission that eliminates carrier waves, allowing for more efficient use of bandwidth. It is commonly used in amateur and professional radio communication. To use SSB on a radio, you will need an SSB transceiver, which can be a separate device or a modification to a standard CB radio.
CB Radio Frequency Bands
In the US, CB radios operate on 40 channels within the 26.965-27.235 MHz frequency range. The Federal Communications Commission (FCC) has strict rules governing the use of CB radios, including the prohibition on using SSB transceivers that can transmit above the CB band. Using an SSB transceiver on a CB radio can result in fines and equipment confiscation.
Commercial vs. Amateur Use
Amateurs are allowed to use SSB transceivers on amateur radio frequencies, but they must obtain a license from the FCC. Commercial use of SSB technology requires a license from the FCC and adherence to strict regulations. If you plan to use SSB technology on a CB radio, you should check with the FCC to determine if you need a license or if your use is permitted.
