Colin Powell's little boy will be giving us BPL any day now and our
problems will be over. [g]

Interesting that CFR Title 47 part 97 states in part:

"Sec. 97.1 Basis and purpose.
The rules and regulations in this part are designed to provide an
amateur radio service having a fundamental purpose as expressed in the
following principles:
(a) Recognition and enhancement of the value of the amateur
service to the public as a voluntary noncommercial communication
service, _particularly with respect to providing emergency
communications_." (emphasis added)

And yet the ARRL reports on the latest BPL news:

"We similarly do not find that Amateur Radio frequencies warrant the
special protection afforded frequencies reserved for international
aeronautical and maritime safety operations," the Commission said.
"While we recognize that amateurs may on occasion assist in providing
emergency communications," the FCC added. It described typical amateur
operations as "routine communications and hobby activities."

I guess during the next forest fire, earthquake, tornado, hurricane,
boating accident or terrorist attack we can just sit back and play
with our toys while all of the real communications takes place on the
Internets, as GWB would say.

Dear BB,

Amen!

My first experience with "dial-up" was in 1965. I was asked to try out
a program in Basic that designed electric motors. You had to dial up
this big main frame in Boston - Dartmouth, I think. We had a teletype
as a terminal and an acoustic modem at 300 baud. The acoustic modem
was a telephone handset with sponge cups for earpiece and mouthpiece
that snugged around the telephone handset. Acoustic coupling means no
electric connection - good for lightning isolation - Hi!

You typed in your Basic program and tried it out. If you wanted to pay
a monthly fee for storage you could save your typed in program on
their disk for a monthly fee. Talk about a text based interface -
primitive doesn't even begin to describe it.

I am tickled to have V.90 at somewhere above 33 kBaud. It makes your
head swim to think about where it will be 5 years from now.

Hi Bob, thanks for the new Smith program. I did have a problem downloading it,
and still don't know if it's all there.

We're returning to Florida early tomorrow morning, and once I get the external
drive connected down there I'll determine if your program is in working order.
If not, I'll email you for a new download.

So far, it looks like a real winner!

Smith Charts went out of date wth slide rules and log tables with the advent
of the pocket calculator.

Be real engineers. Get yourselves into the 21st century.

Hi Reg, Since this is an Amateur Radio Newsgroup, why do you think we
should
all be real engineers? Do you write all of your excellent programs for
the
sole benefit of the real engineers?
I have used your programs, Smith Chart Programs, and a number of others
that
I have found to sucessfully design antennas and matching networks. If I
had to
choose between your programs and the Smith Chart, I would have to say I
like
both.

You're much too tactful, Gary. Are you a politician?

Hey, I still have mine too! In fact, I just dug it out of a 'mystery box'
in the attic. It still works. Back in the 80's, I used in my land survey
business; I wrote a COGO program in BASIC on it that worked like a charm...

An abstract math equation will get one the answer but not necessarily
illustrate what is happening in reality. We see the results of that here
on this newsgroup. The appeal of the Smith Chart is that it gives one
a graphic conceptual grasp of reality while using those same equations
to solve the problem. A picture *is* worth a thousand words. We can
see the (Vfor+Vref)/(Ifor/Iref) impedance displayed right there on
the SWR circle.

Hi Bob,

What a dissapointment - spending so much
time in downloading your progam (three
attempts), only to have it fail in its installation.

Your installer told me I have an outdated file it
needs to replace. Afer allowing - and rebooting
- the installer did not continue. When attempting
another install, I get the same response... ad
infinitum.

I can't deny its small educational value. There are other things besides
transmissions lines. Its worth a single lecture in a 3 year course as are
numerous other graphical methods of illustrating electrical principles..

But unless one is made aware of its limitations and its inaccuracies (which
takes up half the lecture) it can in fact damage an education and turn a
student into an old-wife.

But it's fine for old-timers who've had years of practice and can use it
with their eyes shut as they already know the answer before they start.

It is a paper instrument which assists in performing very simple algebraic
calculations - provided you already know what its all about.

I appreciate its historical, nostalgic, sentimental value. If you gaze at it
long enough it acquires a certain beauty. And it served a very uselul,
time-saving purpose when in vogue during the 1940's.
