I'm running a 2 tone test on my CESSB waveform, and once the compression meter gets over ~6db (there is no true scale on this meter so its an estimate) the waveform begins to flatten. The microphone drive is far below 0db. Increasing the compression past this point continues to increase the distorting of the waveform, and I assume is adding distortion to the audio. I thought that the whole idea of CESSB was to prevent this from occurring? What am I missing?

And unfortunately once you get below -10dB of mic gain your signal drops off tremendously. It has been tough to find, or keep the drive right at the hairy edge of not causing too much distortion and having the drive drop off a lot.0

Hi Mark,
FYI, this technical article in QEX (ARRL) provides a detailed explanation of CESSB, though it doesn't discuss Flex Radio's specific implementation of the technology...
