ESSB Question

in SmartSDR for Windows

Does ESSB allow the Flex radio to capture a wider audio frequency range? OR does it increase the existing audio range waveform accuracy ? Remember this radio captures an analog audio output from the microphone and subsequently digitalized it, processes it and then reconverts it to an analog output for the radio power amplification section.

Thank you.

    Flex radios are capable of ESSB. It just means a wider signal.

    I think there might be some other processing going on as well.

    Not to be confused with Controlled Envelope Single Sideband (CESSB) which limits amplitude overshoot during compression. This allows for nearly distortion free compression. In Flex radios, this gives you a 2.8 dB increase in average (not PEP) power out when using the processor. The distortion is so minimal that I leave my processor on DX+ when I operate sideband. With my KPA500 amp in line, it is like having a kilowatt (almost).
