Thanks Mike. I have subsequently learned that adaptive predistortion will be added at some future date. And, yes CESSB was the subject of a QEX article some time ago. That I know of, the Flex 6000 series are the only ones to have implemented it. SeventyThree(s).

Hi Bob,

All I can report is that there is a sample IN jack on the rear panel.

https://www.youtube.com/c/ElecraftChannel

a 24 minute presentation by Eric.

Nothing on CESSB which sounds a bit like pre distortion by another name
but is possibly a different DSP application. I read about it once a
couple of years ago, in QEX maybe, but cannot remember much about it.

Mike, which one, there are dozens of them. Some as old as two years ago. I have watched a couple, without actually learning anything other that it's a 'game changer', and 'it's better than sliced bread'. I have Googled extensively, but have not found a single hit that includes K4 and CESSB or K4 and predistortion. SeventyThree(s).

Either no-one knows, or no-one cares. OK, let's try this - Does the K4
have/support CESSB or predistortion linearization? SeventyThree(s).
