OK Frostproof Floyd, there you go again, or maybe I should say
"still". Just can't get it together when it comes to ham radio,
can you? You prove it yet one more time.
Speaking of proofs, you've generated a real beauty he
If you think I have insufficient undestanding of Shannon's
infornmation theory that's because you're terribly uninformed
yourself. What my little recited experience showed, when the
PSK was not copyable but the CW ID was, is merely to further
confirm what I said- Shannon and his little mathematical circus
really *DON'T* have anything to do with ham radio. ...
Now Claude Shannon's work is a "little mathematical circus"!
And you've added *EMPHASIS* to the statement that it has nothing
to do with ham radio.
DICK, you've made my point for me and there is very little else
to say.
What the "PSK-NO, CW-YES" incident showed was that Shannon
DOES NOT apply **when the channel is not set by his rules**,
which WAS exactly the case, as is virtually always the case in
ham radio.
Well, there is one other thing to say. But I've stolen this
from Cecil once or twice already, so I'll quote him directly
this time:
"Again, power level is only one of three inter-related
parameters. If they are not all equal, then the playing field
is not level. Your being able to copy the CW ID, which has an
equivalent 12dB power advantage, is like saying a 150w SSB
signal is easier to copy than a 1w CW signal. It's true but it
is also meaningless.
Thanks to DICK CARROLL'S LOGIC, SSB can be proven to be
superior to CW every time. That follows from ignoring any of
the throughput parameters."

Another way of looking at it, is that Shannon's "rules" do
apply, and that is virtually *always* the case in ham radio.
