Q1a: Is there any dectectable radiation?

With your misspell, I almost read that as delectable.

Would certifiably ordinary normal RF spectrum be detectable? It
doesn't even have to meet any spectrum limitations (being at either
end of the extremes) to make that equivocal, why would DC radiation be
any different?

However, there are considerations that are specific to the wavelength
that in a normal or even extra-normal situation would still offer a
simple NO.

It would not be detectable for all the same reasons as the pedestrian
examples: Q, Energy, and S+N/N. DC suffers tremendously for every
criteria.

Energy would be well below the FemtoKelvin range.
S+N/N would be swamped from any of a number of noise sources.
Enough Q would be impossible to obtain to distinguish DC from
GigaMeter wavelength AC sources.

If not, why then do we all seem to agree that charge acceleration causes
radiation?

It's an hackneyed cliché meant to sooth Mensa candidates and their
sponsors.

Q2a: If so, what exactly is the frequency of that radiation?

0

Is this an example of a zero frequency [Or say a very nearly zero, e.g.
~1.0exp(-89) Hz] radio wave?

You are being insecure again.

In the steady state
at DC electric charges are moving at a constant velocity.

You are confusing charge with carrier.
[snip]

I may be, but that is irelevant to the question, for as you well know... the
mere motion of charge, no matter how carried, is all that is germain in the
celebrated Maxwell/Heaviside equations of classical electrodynamics.

Quite the contrary. A carrier always moves charge, but a charge does
not always move a carrier. This is the difference between inductance
and capacitance (which most folks, materialists, think resides
specifically in the coil or the plate).

DC does NOT always involve moving charge or carriers. You defined it
yourself, is your insecurity doubting the initial condition?

One of the most frequent errors in this group is shifting frames of
reference and then trying to convince everyone it isn't a shell game
they are trying to pull.

[snip]
Thus when moving
in a straight line at constant velocity there should be no "waves"
launched
or radiated, no?

Well, are you afore it? or against it?
[snip]

I thought it was obvious, I'll explicitly go on record here...

With Maxwell and Heaviside, I believe that electromagnetic waves are
radiated into space by the acceleration of charge!

Well, there's a brave and bold step forward.

Period, end of story!

Dubious emphasis. Weren't you already convincing with the first
exclamation?


[snip]
My point here is the assertion of the real existence of DC waves either
guided or free!

Edison would have beat Tesla to transferring power over the air if
that were so. Problem is wavelength, you need infinitely long
halfwave antennas - umm, WOW inspiration! That is exactly what
Edison had. He DID beat Tesla with transferring DC power over the air
when he supplied all his customers with antennas. AND they used
guided wave principles.

Phfffttt..

Extremely long dipoles are no problem for those of us who live in the
Restaurant
at the End of the Universe. My dipole extends from there back to epicenter
of
The Big Bang!

Edison was lucky that his subscriber's dipoles all interfered
(physically) with overlapping elements (early linear loading).

Tesla's RF work at transmitting power in Colorado Springs proved he
was oxygen deprived at that elevation.

Bird now sells range slugs that cover the band [1.0E-98Hz - 1.0E-99 Hz]?

I didn't say they offered it, I said that you couldn't afford it.

The question is said Humpty Dumpty, "What is the physical interpertation
of "conjugate match" and "image match" [That's Zo-match for you Zo
affecianados!] at DC.

How do you obtain an infinite reactance to fulfill conjugation?

[snip]
Q6: Below what magic frequency, lets call it f(mgc), do radiation and or
reflection phenomena stop?

A Chebyshev filter might do it.
[snip]

Now you are being silly, the frequency of ripples in the passband of a
Tchebychev
filter [measured in cycles per Hz!] is non-linear and irrelevant to the
present discussion.

The ripples are only in pass-band. Skirt will eventually take care of
DC (after-all there is only one frequency to stop).
