Ah, hate to get technical here, it is just r.r.a.misc, but we do NOT
have the entire block of "A" calls... just AAA-ALZ. Hence A6H belongs
to another land...United Arab Emirates, and i DO not see the Sheik

A side note: a certain ham was issued KB4FU, and proudly got a
callsign tag for his car. Someone in a supermarket commented to his
wife, and suddenly he realized the potential for abuse of his
callsign, phonetically speaking.

He quacked and fussed, and sent the call back to the FCC (for
repairs?) and demanded a new callsign to replace the "obsene" one
first issued...

Those who believe the FCC and the "Higher Power" have no sense of
humor read on: Presently, there appeared on the gent's doorstep

Gary, you mentioned that a typical lightning strike has an energy
of about 20J. Is this really correct? I did a comparison to the energy
stored in a 50uF capacitor charged to 3kV (E=C*V**2), which is 450J,
and I was surprised that the charged cap stored almost 25 times
the energy of a typical lightning strike (not to say that a 50uF filter
cap in an amplifier is anything to sneeze at!). Have I miscalculated
something?

Quite the contrary.  In the 19th century poor telegraph operators were
called "hams" or "plugs"; and the trade schools that turned them out
were called "ham factories".  This is from Edwin Gabler's book "The
American Telegrapher - A social History, 1880-1900"  and it's evident from
the book that Gabler read a lot of the magazines and other literature
addressed to telegraph operators of the period.  Of course that doesn't
prove that "ham radio" derives from "ham operators" of the wire telegraph
days, but it's quite plausible since  at the time ham radio started there
were lots of professional telegraph operators and the radio amateurs were
mere hobbyists.  Nor does Gabler explain how the poor operators came to be
called "hams" or "plugs".

This question ought to be in the FAQ file - it comes up over and over.

Do commercial broadcast stations disconnect their antennas when a
thunderstorm approaches? No. Do their antennas get struck by lightning?
Yes, again and again and again. Do their transmitters sustain damage?
Do their transmitter buildings burn down? Are their operators killed?
No. No. And no. Why? Proper installation. (Truth be told, all of the
above *have* happened at commercial broadcast stations, but in every
case the cause can be traced to, you guessed it, improper installation.)

Proper installation isn't cheap or easy. Make the slightest mistake,
cut the smallest corner, and you open yourself to catastrophic damage.
So what's a ham with limited funds and knowledge to do? Many hams
just disconnect their coaxes and drop them behind the radio. Some who
are a bit more savvy stick the end of the cable in an old mayonaise
jar. Neither trick is satisfactory. If your antenna is struck, there's
going to be around a *million* volts on that cable, that much voltage
can jump 100 inches in air, and it *will* if it has to in order to
reach ground potential.

The only proper way to deal with lightning is to give it a controlled
way to go to ground. It's going to go to ground one way or another,
your only hope is to direct it in a way that's safe for you, your
equipment, and your home.

>I have a heavy ground run to the radio room for grounding the equipment.
>Should the antennas be connected to this, grounding the center conductor
>and sheild?  Should they be grounded and a real lightning rod be installed?
>Or just disconnected from the radio's?

Well just disconnecting from the radio isn't good enough. You've got
to give that lightning a *low impedance* way to reach ground. And that
low impedance path has got to be able to successfully handle 4,000 amperes
of *RF* current. That's what lightning is, nature's own spark transmitter.

Ideally you'll have a ground window installed at your station. (I know
you folks are probably tired of seeing me preach about this, but it is
the best protection you can have.) That ground window will have *every*
wire that enters or leaves your station passing through it via proper
lightning suppressors, including power, telephone, coax, *everything*.
Note, arrange the cabling so that no downlead parallels an interior
station cable run. Otherwise surges will be inductively coupled from
the outside cable to the inside cable bypassing the ground window.

The ground window will be connected *directly* to your ground field
by a straight low inductance conductor. In no case shall the conductor
be less than number 8 solid copper wire, but should really be a wide
copper strap, 5 inch copper flashing is good. (The reason wide copper
strap is preferred is that it's inductive only at its edges, and because
skin effect limits current penetration to only a few thousandths of
an inch so you want as much surface area as possible.) Ideally there
will be no bends in the ground run, but in no case shall there be
any *sharp* bends. That adds inductance.

Note that in *addition* to the ground window, every antenna or support
whose construction will allow it should have a separate ground conductor
run to the station ground field. This will relieve the downleads, and
suppressors, of part of the current load they'll have to carry during
a strike.

A single 8 foot ground rod is *not* an effective ground field. Ideally
we'd copper plate the Earth to form an effective ground field, but that's
impractical. So we make do with driven ground rods. In average soil, a
single 8 foot ground rod will have a resistance to Earth of about 230 ohms.
That will place a connection to that rod at 920 kV during a 4000 ampere
strike. Not good. As currents start to flow into the ground, the soil
becomes temporarily *saturated* with charge. This limits the amount of
current that can be quickly dumped into any individual Earth connection.
So we need a bunch of Earth connections. How many is a bunch? Well good
practice says that the total resistance to Earth should be less than
25 ohms, so that means at least 10 rods are required. How far apart
should the rods be to avoid overlapping saturation zones? The rule of
thumb is that ground rods should be no closer together than the *sum*
of their lengths. That means that any two rods in the ground field
need to be at least 16 feet apart.

The rods should be laid out in a star pattern with the rods connected
to each other by no less than 1.5 inch bare copper strap buried not
less than 18 inches below grade level. Note that these straps can be
considered horizontal ground rods themselves and can reduce the number
of driven rods needed in the system by about a third. So assume 7 rods,
one central and six radial at a 16 foot separation. Make all connections
to the central rod. That's your *single point ground*. Tie power company,
phone company, and CATV grounds to this point as well as attaching your
station ground and separate antenna grounds to this point. Never never
never daisy chain grounds. All grounds must be tied to this single point,
and only to this single point. (Note, if you have a tower, it can serve
as the central rod. With its base planted in concrete, it forms a Ufer
ground superior to a single driven rod. Note too that if you have metallic
underground plumbing, that should also be tied to your single point ground
by a strap connection.)

One more caveat. If your soil is dry sandy soil, or very rocky, you'll
need more rods than for the typical case above. It's OK to extend
your star out beyond the first ground rod, and in this case *only*
it's OK to daisy chain along a radial from one rod to another, but
more than two rods along a single radial reach a point of diminishing
returns. The buried radials themselves, however, make a dandy groundplane
for a vertical antenna and can extend out as far as you like.

I've left out many details in the above system, such as how to deal
with bonding dissimilar metals, always making a *mechanical* connection
as well as an electrical connection (solder *will* melt during a strike),
what constitutes a *proper* lightning suppressor, etc. Entire books have
been written on proper station installations. You should read at least one,
_The National Electrical Code_. And I'd recommend one more, Roger Block's
_The Grounds for Lightning and EMP Protection_.

Ok, that's the *proper* way to protect your station. Now what's the
cheap ham way? Install an *outdoor* bulkhead panel near ground level
and bring all your antenna coaxes through it with bulkhead feedthru
connectors. Drive a rod into the ground at least 100 inches from the
house and bolt a bar to it that has female coax chassis fittings
attached, both shell and center connected to the bar. When a storm
approaches, unscrew all cables from the bulkhead and screw them to
the ground bar. This will keep dangerous currents and voltages *outside*
your house. But that bar is going to reach 900 kV during a strike.
Make sure there's nothing conductive nearby. Obviously *don't* ground
the house bulkhead panel to this rod.

(Note that this cheap approach has several faults. First you've got
to be home to connect the coaxes to the ground bar. Second there is
such a thing as clear sky lightning. Not all strikes occur during
a well defined storm. Third, any cable that passes parallel to the
grounded coaxes is going to have a large surge inductively coupled
into it. And fourth not all lightning is going to come into your
house via your antennas. It can also come in on the power wiring,
the phone wiring, or the CATV wiring. So this method should be
considered a minimum *expedient* only. It does beat a mayonaise
jar.)

Jeff, we thought you were going for AL 0 HA. After all, it's a vanity call
