Call him persistent, even stubborn, but don't call him
a quitter, and
don't count him out. Rebounding from the February 7 disaster
that sank
his first sailboat, the Mollie Milar, David Clark, KB6TAM,
again set
sail April 11 from Cape Town, South Africa, in a new
boat. His goal is
to become the oldest person to sail solo around the world.
Clark will
turn 77 on May 17.
The February maritime disaster in which his sailboat sank
also claimed
the life of his beloved canine companion, Mickey, who
was lost at sea
during the rescue. Clark has named his new vessel Mickey
in the dog's
memory. The new boat is a 34-foot fiberglass hull vessel.
Now some 800 miles out of Cape Town, Clark has been keeping
a daily ham
radio schedule with the Pacific Seafarer's Net on 20
meters, according
to Bob Reed, N6HGG. The net has been running phone patches
so that Clark
can speak with his wife. Clark's next port of call is
St Helena, where
he will take on water and supplies. He expects to reach
there in about
10 days. Reed says Clark has been keeping a daily schedule
on 14.245 MHz
at around 1400 UTC. He's also keeping in touch with South
African hams
at 1500 UTC on 14.195 MHz.
Clark says he expects to be back in Ft Lauderdale, Florida--where
his
journey began in December 1999--sometime between the
middle of June and
the first of July. While Clark has some corporate sponsors,
he's been
funding his trip largely out of his Social Security income
and his
occasional clarinet gigs.

ARRL VEC Manager Bart Jahnke, W9JJ, says the full impact
of license
restructuring--including the elimination of the 13 and
20-WPM Morse
exams--is slowly making itself felt within the amateur
community. "For
the first quarter of 2001, ARRL VEC test session statistics
show that
new and upgrading amateurs continue to earn licenses
at a rate stronger
that that of first quarter 1999 and first quarter 2000,"
he said. "This
is a positive trend that we expect will continue over
the coming
months."
As of the end of March, according to statistics compiled
by Joe Speroni,
AH0A, the FCC showed 684,359 current licensees on its
books, although
the number of active amateurs is believed to be far smaller.
Speroni's
figures show that more than 20,000 new amateurs entered
the hobby over
the past year, while attrition was on the order of 13,600.
Overall, statistics show growth in the number of Extra,
General and
Technician licensees from year-earlier figures, while
the number of
Advanced, Tech Plus and Novice licensees declined.
Jahnke says comparing the ARRL VEC's first quarter 2001
numbers shows
that interest in the Extra class license is up by as
much as 30% over
the first quarters of 1999 and 2000. "Extraordinarily,
interest in the
General license is up 450% to 650%!" he said.
With the change to a new, 50-question Extra class written
element that
combines material formerly covered in the 90 questions
contained within
the old Advanced and Extra tests, some predicted the
Extra test would be
easier to pass. That's not proving to be the case this
year--at least at
ARRL VEC-sponsored sessions, where the Extra pass rate
has declined by
nearly 7% from 1999. Technician and General pass rates
this year have
been up on the order of 10% to 12% from pre-restructuring
rates,
however, at ARRL VEC sessions.
Licensee numbers compiled by Speroni show that the FCC
issued nearly
5400 new licenses in the first quarter of this year--more
than 2230 in
the month of March alone. That compares with around 3730
new hams in the
same quarter last year. As would be expected, the vast
majority of the
newcomers entered the hobby as Technician licensees.
March was one of
only three months in the past year where the number of
new licensees
exceeded 2000. For more information, visit Speroni's

The US Navy, who gave me four years worth of electronics
training in 9
months, took four weeks to teach me how to solder "properly"...
but I
can give a few pointers that will go a long way to ensuring
reliable
joints. and I'll try to avoid getting into "bird caging"
and "jagged
insulation".)
1. Keep it clean.
2. Use ONLY electronics grade flux. DO NOT use pipe fitting
paste flux.
Using only enough to do the job. Keep in mind that after
you are
finished with the joint you have to remove all traces
of flux to keep it
from collecting dirt and moisture. My favorite method
for flux is to use
liquid type and apply it using a little bottle that dentists
use to
apply lacquer... ask your dentist about the little plastic
squeeze
bottle with the metal piece sticking out of the tube...
Be careful with
the flux. Where ever the flux goes, so goes the solder...
keep it under
tight reign. If you allow it to get as far as the insulation
you'll
stand a good chance of wicking (solder running under
the insulation).
3. Clean the solder with isopropyl alcohol (NOT denatured
alcohol)
before you begin. Use a little on a paper towel and clean
it real good.
4. Using too low of a heat setting will cause more damage
than using too
high of a heat setting. The reason will
become clear further on.
5. Repeat to yourself over and over again as you solder,
"I'm-in-two-three, it melts-two-three, I'm out!"... If
it takes you any
longer than that to complete the joint you are taking
too long. Most
likely it is because your heat setting is too low. If
you don't have an
adjustable solder iron, get a more powerful one for this
job.
6. Keep it clean.
7. When applying the solder, do NOT melt the solder on
the iron then
apply the iron to the joint allowing the solder to blob
onto the joint.
This is a very common practice and the cause of most
solder joint
failures... it will cause "cold" solder joints. The plan
of attack is to
apply the iron to both conductors (whatever they may
be, terminal and
wire... two wires, etc) at the same time and place the
solder where they
meet making a "heat bridge" of all three. You want the
conductors
themselves hot enough to melt the solder to allow proper
flow of the
solder throughout the joint. Again, this whole process
should be over
within 4 or 5 seconds of applying the iron. If your heat
is not
sufficient you will take too long to heat the conductors
enough to melt
the solder and you will cause auxiliary damage to the
insulation... This
will also help to avoid wicking. Be cautioned, though,
that too much
heat can cause the solder to "crystallize" and make for
a poor joint as
well. It takes a little practice to figure out the proper
heat setting
for a particular job. After a while you'll know when
you start how much
heat you'll need.
8. Prepare multi strand wires by "tinning" them. Using
the same counting
method in step 5. Tinning applies a small amount of solder
the end of
the wire and makes for faster "joint creation".
9. Keep it clean.
10. Between joints, keep a blob of molten solder on the
tip of the iron.
This will help keep the tip clean by not allowing oxidation
to collect
on the tip. Oxidation inside a joint is a bad thing.
11. Some solder irons come with a small sponge. This sponge
is NOT for
cleaning the solder iron. It is intended to be wetted
with water and
used to "heat shock" the tip of the iron. Clean the tip
well just prior
to starting another "heat bridge" with a clean shop rag.
Just brush off
the excess solder quickly with the rag. (It should be
obvious that a
cotton rag is indicated here) NOW use the sponge to briefly
tap both
sides of the solder iron tip on it to cool it slightly.
This gives you
time to bring the tip in contact with the joint before
oxidation starts
to form on the newly cleaned tip. If the tip is not shiny
when you start
a bridge, it needs to be cleaned again. If it gets dark
gray or black
before you can get in there, heat shock it a little longer
or move a
little faster.
12. Keep it clean.
13. After you remove the heat DO NOT allow the joint
to move until it
hardens over. Even though this happens very quickly,
the slightest
amount of movement can cause the solder to crystallize
and make for a
poor joint.
14. When you get done, clean all traces of flux from the
joint. What you
should see is a very shiny joint with no "pits*" and
smooth concave
sides where the solder tapers off to both sides. If the
sides of the
joint are convex you've used more solder than what was
required. Unless
you are concerned about weight requirements this usually
isn't that big
of a deal. But remember, it all adds up!
*Pits... Pits are bad things. They are caused by various
things... not
having the surfaces clean enough, allowing the tip to
oxidize, not
staying in the joint long enough to allow the flux to
"boil" off. Pits
are bad because they usually contain flux or some other
contaminant and
can lead to corrosion of the joint. That isn't to say
if you have a pit
your joint will fail. Many times, pits can be removed
by reapplying flux
and re-flowing the joint. This can only be done once
or twice before the
solder becomes "tired" and starts to crystallize when
it cools. If it
gets to this point you'll have to remove the solder and
start over
again.
I didn't get into weather proofing and protection methods
here.
Depending on the application you'll want to use either
heat shrink (Wire
to Wire) or High Temp silicone RTV (Wire to terminal).
I STRONGLY
discourage the use of electrical tape of any color. Eventually
it will
turn gummy and start collecting dirt. If you absolutely
insist on using
electrical tape, consider changing it out every so often
and cleaning
the joint between applications.
"We also take this opportunity to point out that the practice
of
identifying only by the last two letters of an Amateur
call sign is a
violation of Part 97 of the Commission's rules. A station
identifying by
only part of its assigned call sign is not complying
with the clearly
written rules regarding station identification, and such
practice must
not be condoned by your group."
