So here we are.



Yup, and no one has persuaded me it can't be done. I've only been persuaded
that we haven't figured out how yet. (Sorta reminds you, doesn't it, of how
those old-tymey hams must have felt when they were told to take their party to
"200 meters and below".) You, Jim, and Dee bemoaning how hard it will be, and
John raising the tantalizing notion that we may only be a few "eureka!!!"s away
from something workable.


He also give a lot of solid technical ways in which this can be done, eh?


Outside my area of competence, but I'll watch the
dialog with interest.


Hey, Hans, ignorance is not a crime! Note that Jim brought up an
*actual* method of trying to do a lot of BW using 256 or more phase
angles that are decoded by the receiving station. That is not likely to
work at HF, but a simplified version of this is used for some satellite
comms. they (see my link in my post to Jim) note that QPSK is more
reliable - or at least suffers less from link degradation - same thing,
than 8PSK. But there is some theory there that can be discussed.

And as for "bemoaning", I have been asking for something based in
solid theory since early in this thread. Most of what I have gotten in
return is that I am an olde tyme ham (untrue) stuck on CW with my Bug
(paraphrased, but laughably untrue), and topic shifted to DRM voice
(technically working, but beside the point). That ain't substance.
