the till, or in the records, or in the stock room.


You are shooting your own argument in the foot. The people you are
describing are *LAW-BREAKERS*, not law-abiders. There are already laws
against what they are doing. They already broke the law and you want
yet another law for them to break??? Why not advocate enforcing the
existing laws which are not being properly enforced? How many laws do
they have to break before you realize that law-breakers don't obey laws?
As I said before, you might as well be advocating laws prohibiting
hurricanes from hitting Florida.

Gun control laws don't keep guns out of the hands of criminals.
Gun control laws keep guns out of the hands of law-abiding people
who need guns to defend themselves against criminals. You and the
criminals would like to see all law-abiding citizens disarmed and
helpless.

In case you missed it: LAW-BREAKERS don't obey laws. They don't obey
the present laws and they won't obey any new laws that you are advocating.
To keep the thread on topic: IMO, you can't see the forest for the trees.

Hi Jack,

This is the gun crowd you are speaking of.

Jack, please explain why we need battlefield weapons in a civilian

That's simple. Because the criminals are armed with battlefield
weapons. Don't know about you, but I think it's stupid to take
my 66 year-old fists to a gunfight.

How many times do you need to shoot that beautiful deer before you
drag it to the sausage maker?


Deer don't shoot back. Criminals, including terrorists do, and
sometimes with fully automatic weapons. The criminals obviously
want the ordinary citizens to be disarmed. But why should you
want exactly the same thing as the criminals?

Did you know that the crime rate is falling in the concealed-carry
states? Did you know that a majority of states are concealed-carry
states? If you were a criminal, would you really want to take on
someone who might be packin' a concealed Colt .45?

Worse than that. I'm lamenting about every Libertarian
presidential candidate losing every single year.

How are your non-weapon negotiations coming with that
250 pound guy in the process of raping your daughter?

The voltage at the ends of a half wave dipole can reach thousands of
volts even with relatively low power. Trees have been set on fire with
as low as 100 watts. Be careful!

==============================
Hi Bill,

A half-wave dipole is a resonant tuned circuit.

A 40 meter dipole using 14-gauge wire has a Q of about 11.

At 100 watts there is 85 volts at the feedpoint.

The voltage between the ends of the antenna is 85 times Q which equals 956
volts.

Therefore, the voltage between one end of the antenna and ground is only 478
volts.

And this falls to a much lower value when the end of the wire is in contact
with anything by virtue of the very high antenna impedance of around 1500
ohms.

Furthermore, the antenna is immediately detuned when it comes into contact
with anything and Tx power falls.

From where do you get your "thousands of volts" - the old wive's monthly
magazines?

There are far more Californian forest fires caused by arsonists than 100
watt transmitters. Fortunately, it doesn't seem to have a bad effect on the
quality of the wine.

I will deal with only one of the misconceptions.

Actual assault weapons have been tightly regulated (in many States,
civilians can not legally own them at all) by the Nation Firearms Act (NFA)
for the past about 70 years. Very, very few crimes have been committed with
such weapons.

The law that just expired contained a definition that was equivalent to
defining the number pi as 3. It defined rifles with certain cosmetic
features as being what they could not be - "assault weapons." The law used
emotive words to make it appear that common rifles were the same as what had
been dealt with by the very old NFA. Even the media showed police owned
machine guns (regulated by the NFA) firing and then left the impression that
those were the rifles covered by the just expired law.

In short: the law that just expired was a fraud - assault weapons continue,
as they have for 70 or so years, to be very tightly regulated.

"If a dipole falls in a forest and there's no one there to hear it,
does it make a sound?"


No, but makes a lot of QRM... ;-)

I assure you we are concentrating very carfefully, Reg! Last week we had
about 20,000 gun laws on the books, counting all federal and state laws.
This weekend we have one less federal gun law, and soon there may be less.
When free people use their minds instead of letting foolish emotions be
their guide, the concept of restricting firearms from law abiding citizens
is one of the first things to go.


Gun control is using both hands.

In any event, if the trees are at all flammable, best use some
non conducting rope (that won't absorb moisture when it rains)
to support the ends of the antenna away from the tree limbs.
The antenna would work better without those lossy tree trunks
right next to the ends anyway.
