Yes Gary, I saw that QEX article and the new one in QEX this month that discusses the possibility of external CESSB processing for existing SSB rigs, and how different types of SSB modulators preserve the CESSB signal or not. He explains there may be benefits to using ECSSB externally even with a rig that do not preserve the ECSSB completely.
Although there are not commercial external ECSSB processors available, in the QEX article there is a link to ECSSB audio test files which can be used to evaluate with a scope looking at the RF envelope whether or not a rig is "ECSSB ready". It will be interesting to test this with my KX3 into a load. The new QEX article: http://www.arrl.org/files/file/QEX_Next_Issue/2016/January_February_2016/Hershberger_QEX_1_16.pdf Perhaps we are going off topic, but no doubt we will hear more about ECSSB in the years to come, and hopefully with their DSP expertise Elecraft will be participating. 73 from David GM4JJJ > On 10 Jan 2016, at 00:49, NC3Z Gary <n...@outlook.com> wrote: > > He had also published an article in QEX in 2014 about CESSB and said > that Flex is implementing it, and if improves the talk power by almost > 3dB.
