Hundreds of technical links without a lot of fanfare
This page is here for the benefit of all those who share similar interests. In
some of these areas I have no experience (Nauru); in others I have very
limited experience (aviation), and in other areas I have more experience
than enthusiasm (ham radio). However I have explored the internet
for information on these topics, and perhaps I can save someone else a little
This page has hundreds of links, and it has become so large that I have split it into
two separate pages. This page is mostly about electronic communications, and the
second page contains other interesting technical topics. All the topics for both
pages are listed below, and if you click on a topic that is not on this page, you will be
sent to the second page automatically. (How clever!)
At last count, there were 481 valid links on this page. Link checking is done periodically,
and the dead links are changed to HTML comments. If I

Some of the newest items have bold titles. That
was accidental, but I think I'll leave it that way.
I've seen this girl before -- in
a single frame of film leader. She was apparently well known to engineers at the BBC.
Martin Ellen wrote in to say, "This is the famous BBC 61A 'Flesh Tone Reference Chart' described
in great detail here."
Dave Buckley is quoted as saying, "The young lady on the make-up chart was a secretary in TV Training
Department (then based at Woodstock Grove, subsequently Elstree Centre
where we were the first department to move in) during the 1970's. Her
name was Lynn ??. I believe she was picked as she had won a Miss BBC
[Further update:] Lynn came third in a Miss Great Britain contest shown on TV and this may have been the
way she got the job of posing for the chart (which must have come in to use around 1976/77 at the earliest).
Update: High-quality reproductions of the Indian Head
Test Pattern are now available. They have been derived from the original artwork, and they
look great! Chuck Pharis really did a good bit of work restoring them. Every
TV station should have an Indian Head Test Pattern in the Engineering office. Order now!
The window pattern was mainly for testing DC response
in video circuits. If there was any smearing in the picture, then you knew there was a
problem with low-frequency response.
This is the good old EIA Linearity Chart
from 1961, also known as the ball chart.
In the 1970s, if your color cameras had registration problems, the ball chart would show them to you. You
see, the cameras had separate tubes for red, green and blue (RGB). After the RGB signals go through the
NTSC encoder, and sync is added, it is then called composite video. If you point your Norelco
PC-70 at this chart and the black circles have rainbows around the edges, you need to twist some knobs to
get the red, green and blue pictures to coincide. But it wasn't that easy -- the adjustments interacted
with each other, so it was all but impossible to make a perfect picture, especially if the cameras hadn't
warmed up yet. ("Hurry up -- we go on the air in ten minutes!")
Old glass slides from KRLD-TV are being transferred to computer-viewable form. The
old test pattern looks really good. See the photos at the bottom

These are just notes I have collected while browsing for very bright LED products at affordable prices
(in quantities of 15 or 20 at a time). At the moment, the links in this section are shown in no
particular order. If some links are bold and others are not, it is only the result of the
mood I was in when editing the links. (Have I mentioned that 100% of the HTML code on this site is
hand-written with plain text editors?)
Read all about my experiences with long strings of
super-bright LED's! My great innovation was a method of
feeding 20 milliamps of
current through a group of about a dozen LED's connected in series, rather than
feeding them one at a time, each through its own dropping resistor.
Many consumers (like me) see nothing wrong with good old reliable incandescent bulbs, and object to the
recent mandatory moves that would outlaw them. This started under President Bush ("43"), so it doesn't
matter which party is in office, that's the direction we're headed if the public doesn't object.
More information about compact fluorescent bulbs can be
found here. I'm not a big fan, as you
Only very recently have LED "bulbs" shown up on store shelves, and unless you shop on the internet, the
prices are still quite high, and most of the products I've seen are spotlights and accent lights rather
than omnidirectional "bulbs." Drop-in replacements for ordinary light bulbs are hard to find, but
there is a company
called Luminosity LED offering
such a device already. Again, the internet is the marketplace for merchandise on the leading edge

brightens. White LEDs currently offer an efficiency of around 20 lumens (lm) per
watt, which is better than incandescent light bulbs, but not high enough to compete with
fluorescent lights that have an efficiency rating of from 60 to 100 lm/W.
There are about 716,672 licensed
hams in the US. But that number includes the licenses of a substantial number of deceased
individuals, since the licenses are good for ten years. It also includes huge numbers of
inactive hams like my wife and me, and people who have a license but have never been on the air, like
my son. (None of us have been on the air at any time in this
century.) FRS walkie-talkies do everything we need, so we got rid of our two-meter radios.
Even though the tests for ham operator licenses have been dumbed down considerably, in my estimation, there are many more
obstacles for the average person to avoid these days when operating a ham station. I'm not talking about
tower registration or rules about RF exposure limits. I mean the wide variety of interference sources
that share the radio spectrum. There are twice as many TV stations on the air today as there were
30 years ago, and probably three times as many FM stations. Not to mention cell phones, high-speed
digital signals and personal computers all over the neighborhood. Ham operators generally have to accept
interference without generating any, and that's not easy.
Get the lead out: What would electronics be without
solder? John Burke, the senior manager of Optichron, an electrical components manufacturer in
Fremont, Calif., [says], "There is absolutely no evidence that there is any reason for taking lead
out of solder. There was no reason to do it in the first place, the replacement
is ecologically more damaging, and, by the way, the replacement is less reliable."
Bibliography for Designing Lead-Free
Electronics. The higher processing temperatures of lead-free solders, along with
all of these new failure modes, have dramatically reduced the quality, reliability, and longevity
of RoHS-compliant electronics — produced since early 2006 — versus equivalent
tin/lead- based electronics that were manufactured from about 1950 through 2005.
The Editor says...
Newspaper articles about ham radio are relatively scarce, and accurate articles are quite rare.

resulting short circuits have caused up to $10 billion in damage since they first were noticed in the

Transmit Audio with a Laser Pen. Convoy! Originally,
a license was required for Citizens' Band radio, but masses of people simply broke the law
and operated without a license until the FCC was forced to bow to reality. Citizens'
Band radio became popular because of widespread resistance to the unpopular
55-mile-per-hour speed limit.
Editor's Note: I knew only
a few people who were into CB radio before 1974. One of them was my Driver Education
teacher (in the summer of 1970) who was very careful to obey all the rules about proper
identification and so on. It was only when the 55 mph speed limit went into effect
that 11 meters really became known as the "Criminal Band", and things like licensing
and station identification and power limits were universally ignored.
Silencing the Voice
of America: [Scroll down] As the article makes clear, the VOA service is marginal, at best:
it gets an audience of roughly 8 million people. But those 8 million are without any other news
source. And they can be relied on to spread what they hear on the radio throughout their communities and
networks, providing an invaluable check on the state radio monopoly. (India is a democracy, but it's not
always a nice one, and communal riots and massacres often go unreported on state airwaves.)

the country that the devices used by service personnel with young children interfere with local radio frequencies.
My GMDSS Operator/Maintainer license was issued on June 23, 2005. It looks very much like a ham radio
license. (Pictures at the bottom of this page.) A
search of the FCC database [on 6/23/2005] shows that there are currently 5201 GMDSS Operator
licenses, 404 GMDSS Maintainer licenses, and 377 GMDSS Operator/Maintainer licenses.
GMDSS replaces the old Morse code system for maritime distress messages and other urgent traffic. The
FCC database shows that there are currently 1919 active (unexpired) Radiotelegraph Operator licenses,
but this number is sure to steadily decrease. As far as I have
been able to determine, everyone who holds a Radiotelegraph Operator
license also has a ham radio license.
I have just finished two pages dedicated to a little-known FCC document from 1958

resulted in nothing but gibberish, so I had to do it the hard way.) The pages

Change: Energy Boon or Waste of Time? At 2 a.m. on March 11 the United States

standards since 1986. In 2005 Congress passed a mammoth new energy bill that includes a
controversial month-long extension of daylight saving time.
Saving Time Facts: Contrary to popular belief, no federal rule mandates that states or territories
observe daylight saving time. Most U.S. residents set their clocks one hour forward in spring and one
hour back in fall. But people in Hawaii and most of Arizona — along with the U.S. territories
of Puerto Rico, American Samoa, and the Virgin Islands — will do nothing.
daylight saving scam. Four years ago, Congress in its infinite wisdom extended daylight
saving time (DST) by a month, with the goal of saving energy. Lots of energy. The bill's
champion, Rep. Edward J. Markey, Massachusetts Democrat, said it would save consumers a generous
$4.4 billion over 15 years. Of course, Mr. Markey was just repeating what has long been
an established truism among policymakers: Setting the clocks forward in the spring saves energy
because people don't have to turn their lights on as much as at night. Just one problem.
While daylight saving time might "save" daylight, it doesn't appear to save energy. In fact, it
very well might do the opposite.
Railroads pushed the
uniformity in time across the United States in the late 1880s. "Welcome to Cleveland!" a train
conductor may have told passengers in 1890. "Set your watches ahead 33 minutes!" Travelers from
Cincinnati, however, would have been advised to move up 11 minutes. And anyone planning to catch
another train would have been warned to keep their own time and ignore the clocks of Cleveland. ... It didn't
matter until railroads started covering greater distances at faster speeds.
"Pardon Me, Soldier, but
Would You Happen to Have the Atomic Time?" "If GPS is disrupted or jammed, a CSAC could provide precise time to the GPS

GPS receivers with erroneous information. The hope is that the Soldier wouldn't even know that his GPS is being jammed."

Until UNIX Time Overflows. The problem springs from the use of a 32-bit signed integer to store a time value, as a number
of seconds since 00:00:00 UTC on Thursday, 1 January 1970, a practice begun in early UNIX systems with the standard C library
data structure time_t. On January 19, 2038, at 03:14:08 UTC that integer will overflow. It's not difficult to
come up with cases where the problem could be real today. Imagine a mortgage amortization program projecting payments out

remember that?) It worked on the one occasion I tried it, in about 1969.
Sidebar discussion: I got interested in ham radio (and the study of the precise
time-of-day) back in 1967 because of WWV. I had tampered with my
new transistor radio in a successful attempt to move it into the shortwave bands,
and I ran across WWV, probably on 2500 kHz. Back then, WWV was identified
in Morse Code every five minutes. After learning the code, I got into ham radio,

For what it's worth,
federal law 15 USC §260: The

Another related topic: The

to 2.54 centimeters so that the International foot is exactly equal to 0.3048 meters.
Atomic clocks mark standard one-second intervals, and the date and time of each mark is assigned by
some other system. When a leap second is inserted, the clocks are not stopped for one
second. That's a fallacy commonly reported by the dumbed-down news media. The extra second
is assigned the time of 23:59:60, and normal counting resumes at the end of the leap second. The
leap second does not add one second to your life (as often reported), just as February 29 does not
add a day to your life.
This year's Y2K: 'Leap second'
threatens to break the Internet. The problem is that the computer software controlling
much of the Web doesn't play nicely with leap seconds. The previous leap second, which took place in
2012, brought down Reddit, Yelp (YELP), LinkedIn (LNKD, Tech30), FourSquare, Gawker and StumbleUpon, among
other sites and apps. Qantas' entire computer system went down for hours, forcing employees to check in
passengers by hand. The code for most Web apps is based on Unix, software that traces its roots to
1970 — two years before leap seconds ever existed.

"Leap second" bugs take out some prominent websites.
It was a rough weekend for the internet. While Friday's problems with Amazon Web Services and other sites could be chalked up to some wicked

'Leap Second' Bug Wreaks Havoc Across Web.
On Saturday, at midnight Greenwich Mean Time, as June turned into July, the Earth's official time keepers held their clocks back by a single second in
order to keep them in sync with the planet's daily rotation, and according to reports from across the web, some of the net's fundamental software
platforms — including the Linux operating system and the Java application platform — were unable to cope with the extra second.
Years earlier... 2008 to be extended
by one second. Those eager to see 2008 come to a close will have to wait a second longer. A single
leap second will be added at the end of the year to accommodate a subtle slow-down in the Earth's rotation.
Tick tock ... tick: Extra
second added to 2008. Among the reasons for Earth's slowing whirl on its axis are the braking
action of tides, snow or the lack of it at the polar ice caps, solar wind, space dust and magnetic storms,
according to the U.S. Commerce Department's National Institute of Standards and Technology, another
timekeeper. By contrast, a leap day, February 29, occurs once every four years because a complete
turn around the sun -- our year with all its seasons -- takes about 365 days and six hours.
What is Earth Orientation? There are
various factors which cause the orientation of the Earth to change with time. Polar motion is caused,
in part, by large scale movements of water and changes in the atmospheric angular momentum. For example,
the yearly melting of snow and ice in northern Spring contributes to the annual term of polar motion.
It is also thought that large earthquakes and the embayment of water by dams and reservoirs might affect
polar motion, but this has yet to be quantitatively demonstrated.
Chile quake may have tipped
Earth's axis. The massive earthquake that struck Chile on Saturday may have shifted Earth's axis
and created shorter days, scientists at NASA say. The change is negligible, but permanent: Each day
should be 1.26 microseconds shorter, according to preliminary calculations.
Earthquake Shortened Days, Increased Earth's Wobble. Earth naturally wobbles slightly as it
spins, because shifting surface mass such as melting glaciers and moving ocean currents can throw the planet
off balance. Data from high-precision GPS instruments show that parts of Japan shifted by as much as
13 feet (4 meters) as the fault plates lurched due to the earthquake. This allowed scientists
to calculate how much Earth's overall mass distribution had shifted and thus how much the wobble was affected.
The shifting mass also affected the planet's spin rate, according to geophysicist Richard Gross, of NASA's Jet
Propulsion Laboratory in Pasadena, California.
The One-second War. As more and more
systems care about time at the second and sub-second level, finding a lasting solution to the leap seconds
problem is becoming increasingly urgent.
This is a roundabout way of saying the Windows
Time service makes no provision for leap seconds. How the Windows Time service treats a leap second:
After the leap second occurs, the NTP client that is running Windows Time service is one second faster than
the actual time. This difference is resolved at the next time synchronization.
complete list of area codes (alphabetical). There are 25 area codes
in Texas. I remember when there were only six. The explosion of phone
numbers occurred because every fax machine, cell phone, voice mail box and pager has
its own number, and every 15-year-old kid in town has a cell phone. Many
medium-sized businesses no longer have switchboard operators; they have PBX's
so you can dial any extension directly. And phone numbers are (apparently)
assigned in blocks of 10,000 to various phone companies.
If I were to guess, I would say Fort Worth is the largest city in
the U.S. which has not undergone a change of area codes. Or possibly El Paso.
The first digit of an area code is
never 0 or 1, and the second digit is never 9.

Technology Facilitates Caller ID Spoofing. In
the last few years, Caller ID spoofing has become much easier. Millions of people have Internet telephone
equipment that can be set to make any number appear on a Caller ID system. And several Web sites have
sprung up to provide Caller ID spoofing services, eliminating the need for any special hardware.
Spoofing scams make
caller ID untrustworthy. Spoofing makes use of services that allow callers to disguise the number they
are calling from. ... The service is legal, and spoofing companies point out that even law enforcement agencies use
it as an investigative tool.

phone companies to secure their systems?]

spooky caller ID-faking services hit UK. Communications watchdogs have today been pressed by MPs
to investigate a new service that allows people to fool caller ID systems into displaying a fake number, amid

in the UK. So-called caller ID spoofing services have been available in the US for several years.

New York Town Kills Cell Tower. In
a move that broadband advocates fear is part of an increasing trend, a small grassroots group forced the town
government in the Westchester County suburb of Lewisboro, New York to back out of a deal with the governing
board of a local church that had agreed to serve as a site for a cellular tower. The antenna would have
been mounted inside the church's steeple, making it rise about 50 feet higher into the air, and would
have been invisible to the surrounding area, which had long been prone to dropped calls and dead zones.
The Editor says...
It's too bad that all three sides couldn't lose. Here we have a church that is willing to
prostitute its steeple as a cell phone site. The church is hoping to profit by accomodating the
people who can't bear to live without continuous cell phone contact. Then there are the
"community" busybodies who want to meddle with other people's use of private property. They all
deserve each other.
