It's easy to throw equipment
in a box and then send it
off for repair or for use
elsewhere. United Parcel
Service and Federal Express
have guidelines on how items
should be packed to assure
they arrive safely. Even if
you insure a shipment, you
may not be able to claim
shipping damage if you did
not do a good job packing in
the first place. You need to
do your part.

Before you put equipment in
a box, check to see if
everything inside the
equipment is secure.
An example is the modulated
oscillator in an FM exciter.
The oscillator module is
often attached to rubber
shock mounts. It is common
to find the oscillator has
broken loose from its mounts
and is rattling around
causing damage during
shipment. Ouch!
Fig.1 shows how it goes
wrong. Best to put foam
rubber in to keep it secure.
Tighten any screws on
terminal strips, too. They
can easily work their way
out with vibration in
shipping. This may seem like
a small point, but it is a
hassle when some are
missing.
Each shipment is different,
so there is no single
answer. For starters, use a
corrugated cardboard box.
You should have 2 inches of
packing material between the
item and the inside of the
shipping box. That usually
means rolling the item in
bubble wrap. To get 2 inches
means multiple layers of
bubble wrap, taped to keep
it from unrolling. Since the
box is likely to be wider
than necessary, you can use
packing peanuts, packing
pillows, or even an old
Radio World wrinkled up to
fill the remaining space.
Figs. 2, 3 and 4 all
illustrate items that were
not packaged correctly.

MORE PRACTICAL
SUGGESTIONS
If the equipment you are
shipping has a front panel
that you want to protect
from damage, you might use
an extra piece of cardboard
on that side of the shipping
box to double the thickness.
Cut another box apart using
tin snips to get that extra
cardboard. Repeat that for
any other vulnerable sides,
in case the box is stabbed
or gashed during shipping.
It only takes a few minutes
to get it right and to
prevent hours of haggle over
an insurance claim.

If you are shipping an
analog meter, put a wire
across the meter terminals.
This will "short" the meter
movement so the needle is
far less likely to swing
wildly in transit. The more
sensitive the meter
movement, the more likely it
is to be damaged in
shipment. Remember, packages
vibrate during every mile of
transit by truck or
airplane. The vibration is
unavoidable.
Fig. 5 shows one of six
Harris MW-1A PA modules
received at our repair shop.
Fortunately, this one
arrived safely, but packing
peanuts completely inundated
it. Peanuts were not
"inside" the module when it
was packed, but vibration
and movement in shipping
forced peanuts into spaces
that were difficult to
reach. It took 20 minutes of
billable shop time to clean
six modules. That included
partially disassembling two
of them to extricate peanut
fragments.
The client would likely be
very angry if we returned
the modules to him with the
same peanut problem. You
really need to think ahead
when packing for shipment.

another one wrapped for
shipment.

Don't get me wrong, packing
peanuts are a good choice.
Wrap an object and put it in
a box. Pour packing peanuts
around to fill the gaps.
Don't close the box yet.
Shake/bounce the box to get
the peanuts to settle, then
add more peanuts. This will
lessen the chance of
movement in the box.
Also, always
include some contact
information inside the box.
A business card will do.
Sometimes shipping labels
are accidentally torn off
packages. The only way the
shipping company will know
how to find the owner is by
looking inside the box. Your
expensive FM exciter could
become "unclaimed freight"
If you are shipping an item
for repair, be sure to
include a return shipping
address, contact information
for payment, and a
description of the equipment
problem, which will help the
repair tech in his job. This
is especially true if the
equipment problem is
intermittent. As we all
know, intermittent problems
rarely show up on a service
bench. Give as much
information as you can.
Remove any labels from the
outside of the box,
especially any bar codes, so
today's shipper won't be
confused about where the
package goes. Use a heat gun
to warm labels so the
adhesive softens and lets go
when you pull on a corner.
If you absolutely cannot get
a barcoded label off, then
cover it with at least two
layers of colored tape,
preferably three layers, so
it cannot be read. Remove or
cover any labels that do not
apply to this shipment. That
especially applies to
"hazardous materials"
labels.
Do not use string or rope to
hold a box closed. Several
layers of 2-inch-wide
packaging tape on all box
seams appears to be the
right approach. Flip the box
over and check its bottom;
it may need help there too.
When affixing a new label,
do not put it on top of
packing tape. Shippers want
you to put the label on the
box itself. Packing tape can
tear off, along with any
labels.
If you are tasked with
measuring the dimensions and
weighing the box before
shipment, best to read high.
For example, if the box is
18-1/4-inches long, you note
it as being 19 inches long.
If it weighs in at exactly
20 pounds on your scale,
write it up as 21 pounds.
Shippers often check
packages and rewrite the
charges. This could be a
problem if you have already
told the recipient what the
shipping charge will be.
Knowing the facts will help
you get the job done right.
