>I studied DFCW and the linear requirement is not possible of course.

followed by

to avoid misunderstandings : DFCW does not need linear amplification.

I have just looked around and I can not find the file I referenced, please
send me a description of DFCW, I am of the impression, apparently wrong,
that DFCW involved dual frequencies, which I have interpreted as
simultaneous dual frequencies, which is apparently wrong.

Please send a description of DFCW, I want to understand it.

Thanks es 73
