When you transmit SSB your voice is upconverted to the radio frequency spectrum, amplified, and radiated out of the antenna. Block diagram of a 20m SSB transmitter.

Abstract: In order to solve the serious interference problem due to the overlapping subcarriers of USB (upper side band) and LSB (lower side band) spectrums in the conventional DFT-s-SSB-OFDM ...

This is a simple and experimental modification that transforms a QCX into a (Class-E driven) SSB transceiver. It can be used to make QRP SSB contacts, or (in combination with a PC) used for the ...
