Anyone who had placed orders with CW Crystals and still waiting, just

 When I connected my KAM to the acc jack of my TS440, I had to install
a diode between two pins in the connector (that's a hellashous connector!)
Kantronics supplied that info and I since saw it in QST (H&K ?) for the PK232.
The diode was, I believe, a 1N914.  Send me mail for more info at:

Home Depot sells a workbench based on 2x6 construction for $40. I've
built two, the latest last Monday. They're sturdy, come pre-cut and
pre-drilled, and with all the necessary assembly screws. It'll comfortably
support a small block Chevy engine, so it does a fine job with amateur
boat anchors. All you need to make it a great electronics bench is to
glue down a fiberboard top to get a smooth work surface.

Or you can go with a couple of short filing cabinets and a solid core
door. I've done that too. The key is to get the working surface to a
height of 38-40 inches so you can comfortably work standing or sitting
on a stool.

If you work on boat anchors a lot, look at getting one of the roll
around mechanic's tool box *bottoms*. With a rubber mat on top, it
makes a fine place to set that heavy radio, and allows you easy
access to all sides of it.

>(I probably ought to have something to clip an anti static wrist strap
>to for one.)

You should get some computer room anti-static carpet for the benchtop.
This stuff is often free in small quantities from the carpet house.
This can serve two purposes, it'll prevent marring the faces of equipment
that you're working on, and it forms a convienent static mat, just clip
your wrist strap to it. Don't glue it down, there are times when you'll
prefer to work on the bare benchtop. You're not looking for a connection
to Earth, all your anti-static station is supposed to do is to establish
a zone of common potential. That can imply a connection to the third
wire of the power system so your test equipment will be at the same
potential, but a low impedance Earth ground is not wanted.

I prefer to mount my scopes, spectrum analysers, and communications
monitors on roll around scope carts. I can then drag out just what
I need for a particular task. Cluttering the back of your bench with
a bunch of fixed test equipment results in the bench being covered by
a slew of dangling test leads with the one you need at the moment
about an inch too short. Do mount a heavy 12 volt supply on the bench,
and a variable lab supply. You'll need those all the time. Both should
have settable current limiting.

The basement tile is likely better than non-conductive carpet, but
you can still have static problems from your clothing. Wear cotton
rather than synthetics, and use that wrist strap to the conductive
pad the equipment is resting on. The dangers of static are somewhat
overblown in most cases. If you're working with unterminated MOSFETS,
then static precautions are wise, but most equipment won't be bothered
by static as long as the sensitive devices are terminated in the
circuit.

If we assume this is a workbench and not an operating position, then
ground concerns should be limited to *safety* grounds. The third wire
ground of the equipment should be sufficient for this. Your bench power
strips should be fed by GFI breakers, and you may want a 1:1 isolation
transformer for devices under test. You definitely want a "panic" switch
within reach that will allow you to disconnect power quickly in case of
a problem. You'll be working on equipment with exposed dangerous voltages.
Great care must be taken to assure you don't get zapped. I like to have
a separate power strip for my test equipment and for equipment under
test. The latter has a permanently wired red lightbulb. I can tell at
a glance whether there is power to the equipment. A single switch can
turn this strip on and off. I use that rather than pulling the plug
again and again while working. Note, you can get exciting results by
touching a grounded tip soldering iron to a circuit that is powered. :-(

                                                 . .  :.

Hello David. Good luck with your new work bench. I spent over 10 years of
my working life at the electronics work-bench- so I reckon I'm qualified
to comment on this one.

Pay close attention to the height- remember that you will be spending many
happy hours (hopefully) there- nobody wants back problems in middle-life. If
you are going to use a lab type stool, make it so that you can get your legs
under the bench.

Keep in mind that fluorescent tube lighting can cause radio noise, and
interfere with microvolt measurements, so it's a good idea to have an
ordinary incandescent (filament) lamp on a goose-neck so that you can get
plenty of noise-free light right onto the job.

Have all your most often needed tools in plain view on a shadow or
peg-board (few things are more time-wasting or frustrating than scratching
around in a drawer full of bits 'n pieces looking for a blade screw-
driver!), and make it a rule that other persons in your house must always
put tools back where they borrowed 'em from (fat chance!).

Arrange plenty of ac power points along the back and front of the work
bench. If you can afford it, have them isolated via a 1:1 transformer of
suitable kVA rating- or use a core-balance relay- good insurance.


Satic electricity should not be a problem in a basement set-up. Have a
rubber-backed mat to stand on when working with high voltages.

73, Drew,
VK3XU.

Ah, those huge whips are for a different band, somewhere in the HF
spectrum, not for VHF/UHF. The only bumper mount VHF antenna I've
seen in years is one by Hustler that puts a coaxial sleeve dipole
on one of their HF antenna masts. I used that one years ago on a
67 Chevy, alternating the VHF top section with a HF top section.
A Comet, Larsen, Diamond, etc roof mount dedicated VHF or UHF
antenna will work better *on VHF/UHF* than a bumper mount at those
frequencies. Bumper mounts are *mechanically* the best solution for
very long HF antennas. VHF/UHF antennas generally aren't very long.

Don't believe a word of it. Morris dancing is entirely a myth, as a
traditional art. It was actually invented by a bunch of students
from Oxford who were on their way to Wales for a folk-festival
in 1964.

They were motoring up the road in a clapped out Morris 1000 when the
SU fuel pump packed up.

They all piled out of the miserable old motor, and stood about looking
glum. Going off to the bushes to have a piss, one of them returned with
a bit of wood that he thought would make a smashing swagger stick.

When he returned to the car, one of his comrades, who wasn't very popular,
had pulled out his wheezy old melodeon and began to play what he thought
passed for a jig, only he never could get the timing quite right, and
had to slow down in order to get all the notes in some of the passages;
neither he nor his melodeon were much good at making music.

Motivated by the contents of a couple of bottles found in the boot,
and by memory of a course in modern dance which they had taken when
they had mistakenly thought they were signing up for crew, and
hampered by the contents of a couple of bottles found in the boot,
the other lads began to improvise a modern dance to the strange
wheezings of the melodeon. The driver, meanwhile, decided to have
'one more go' at starting Minor--- ---anything to get away from the
racket.

In any case, just as the lad with the stick came 'round the back fender
of the car in the midst of his Isadora Duncan impersonation, he  managed
to whack the car with his stick. "Oi, oi, oi, mind finish!" says the
poor old rust-pile's owner.

Just then, the Morris came to life, the jolt of the dancer's stick
having temporarily unstuck the contacts which motivate the fuel
pump's oscillations.

Some sixty miles later, the scene was repeated, but the lads knew
just what to do. As the engine starved and died, they would pull
to the side of the road, get out the melodeon and the stick, and
perform what came to be called the "Morris Dance," which got them
all the way to the folk-festival and back.

The original Morris from which this dance originated can be seen,
now preserved as a living memorial, just round the corner from Cecil
Sharpe House. Unless someone's nicked it again.

Be sure to put a 1 by 4 or 1 by 6 along the back edge of the bench.
This will prevent screws, resistors, and other parts from falling off
the back.  This event always happens at the most inoportune time.
My bench is plywood over 2x4's built as an interlocking frame.  I
work on electronics, household projects, and do woodworking, so
it had to be sturdy.  For a decent surface I laminated a piece of
fiberboard to the surface.

One thing that is not immediately obvious is to put the bench where you
will have an overhead light over the bench.  I need to move a ceiling
fixture in a suspended ceiling, which is easy.  If you work area does
not have lighting above the bench you will constantly be working
in a shadow.
