OK, I get it. You didn't _really_ mean it, but you had to paint that

Yes. That's exactly it. The mechanism has one notable name that I use,
and that's "symbolism." And yes, it's an effort to paint a word picture
to impart a concept that words alone, linearly, fail to impart, for
whatever reason.

Another, similar tool, is "satire," albeit it's generally intended
to relieve the pain through laughter, rather than simple revenge
fantasies.

Theo van Gogh, a brilliant Dutch cineast and writer, sort of
our version of Michael Moore, was a great master of figurative
language. I say 'was' because he was killed this morning.
I guess by someone who didn't understand him either.

---
Perhaps the lack of understanding was on van Gogh's part?

Evidently. One of his own denials got him.

The subject he was refering to was a little more specific. He was

Kerry opposed the war, but I don't think you can find a reference
where he said that the who thing was an atrocity. He was refering to
more specific items than this.

Actually,Kerry was intentionally general in his accusations.
It's harder to prove such generalizations,and consistent with the Kerry
modus operandi.

Hi

Tektronix has recently launched a new TPS2000 series cheap scopes that

Does anyone know how they acchieve the 600VRMS isolation with the aid
of the P5120 passive probe? (30VRMS with a standard P2220 probe)

How is the isolation done inside the scope? Its quite cheap, around
5k$ with 4 probes and with nice 200MHz bandwidth performance.....

How about a differential input amplifier?

Too complex;look at the 7A13 diff amp plug-in for 7000 series lab scopes.
I suspect it's done along the lines of an A6902 isolation system.

Dear Paul,

Like your contemporaries and products of the educational system, you
over-complicate matters. Looking in advance for problems where none probably
exist. Which signifies a degree of lack in self-confidence.

You're undoubtedly right; certainly in matters electronic, anyway.

Who needs Kirchoff and the other theorem writers? Myself I've hardly ever
heard of Kirchoff except in these newsgroups. If you want to convince me in
a technical argument, quoting Kirchoff or Terman is wasted effort. I doubt
if it convinces others.

When was the last time Kirchoff or Terman ever solve one of your (or anybody
else's) genuine PRACTICAL problems?

I assume you mean Thevenin? His is a useful way to visualise some
basic resistance/impedance stuff. I do resort to it quite frequently.
Kirchoff, very much less so.

Things worked out OK for me. But then, I take a different viewpoint - I'm
self-educated. Beyond reading and writing up to the age of 14 I am not a
product of the 40-years debased UK technical educational system.

I'm sure you appreciate I have not the slightest ill-will against your
only-to-be-expected views. But you may wish to take into account that I have
just consumed a bottle of cheap plonk - a claret.

In vino veritas, Reg; in vino veritas.

I have grave doubts that I'm cut out for higher electronics. I can't
see things the way you intuitive types can (could the skill be
cultivated somehow?) My natural talents lie in other areas but
electronics is a life-long interest and I'd like to do a little better
at it than I do!

Any tips and suggestions readily welcomed!

I wouldn't worry about the "talents" a lot of us have a lot of different

Get a meter and a soldering iron and some parts and a proto-board or
one of those 101-in-1 kits, and read a lot. I always used to hang out at
621.384 in the Library. And I think the book that I knew as "The
Radio Amateurs' Handbook" goes by a different name now, and I'm sure
that someone will help out here. A lot of people say a lot of good
stuff about AoE, but I can't speak at that, other than that I highly
respect Win Hill and am consistently impressed with his knowledge
and the way he presents it.

Have Fun, and welcome to the snake pit! ;-)

If you can.

And I don't mean take "atrocities" and change it to "war crimes" with

I think you have a point there. The same goes for some of those 'panacea
chips' that try to solve a whole barrage of tasks at once but only for a
tiny sliver of a market. They often tend to be short-lived as a product.

I'm constantly amazed at how many different voltage references, regulators
with fixed output voltages, watchdog timers with preset timeouts, etc. that
the likes of Maxim and Analog Devices put out these days. Unless you're
buying 50,000 for a lifetime purchase, it seems pretty iffy whether or not
that 2.834V reference is still giong to be around in a year or two.

Use a TL431 ! You'll be in good company.

Just listened to Kerry admit to atrocities in Vietnam this morning
on Meet the Press. Who is being duped by whom?

I heard the same show. Clean the wax out of your ears.

--

Here's the transcript (notice the repeated "yes"):

(Videotape, April 18, 1971):

MR. KERRY: There are all kinds of atrocities, and I would have to say
that, yes, yes, I committed the same kind of atrocities as thousands
of other soldiers have committed.

Note the "as thousands of other soldiers" and the fact that he did not
say that he committed "war crimes". He is confessing to being a part
of something he now regrets not confessing to any type of crime. It
is very clear.


Still,Kerry said clearly that HE committed atrocities(that were war
crimes).That's what the whole Kerry testomony was about;WAR CRIMES.

Please stop weaseling,you're too much like Kerry.

The die is cast there is nothing we can do about it anymore so the debate
is now meaningless.

Philips.


Does it really have to be a disk?

Coil craft makes inductors that are two disks with a very short rod core
between them. The whole thing is less than 1/8" thick and surface mounts.
You could try one of them.

For UHF radios, some kind of noise appeared at receiver radio's

happened even when the microphone was disabled/unplugged from the
transmitting radio. I don't see any way that the noise could be
coupled to the microphone. The noise amplitude (as audible) was much
more lower when antenna was detached. What actually happened there? No
such peculiar phenomena was been observed in VHF radios though. I
suppose it's the interaction between the key chain and RF radiation
field, and caused VCO pulling?

Vibrating keys causing Doppler modulation in the near field if the Tx
antenna. Are the receivers FM?

Not a disc, but how about a surface-mount ferrite inductor? Don't
connect the coil but use it as a lump of ferrite. Farnell has loads,
for example 305-6510 is 0805 size.
