A Few Words on the National Traffic System

26 Mar

The link below will take you to the April QNI the NTS Newsletter, published each month by James Wades WB8SIW. In it you will find several articles on the National Traffic System and its involvement with ARES and the public service. NTS has been declared a “white elephant” by many because of its slowness compared to modern technology. If this is so then why do you find so many capable operators each day manning the microphones, the Morse keys and their keyboards to ensure that message traffic is passed seamlessly across the country and now even to Europe.

Most new hams have no idea what NTS means or what its purpose is. Several hams across the country, this station included, spend an hour or two every other day generating welcome messages to new hams as well as to recent upgrades. For most, this is their first radiogram, and for some it won’t be the last. It is to these young hands that we, the older generation, hope to pass the torch one day.

Something A Little Annoying

27 Dec

This is definitely not radio-related but it nonetheless irritates me to no end.

Last night, around 3:00 am, while at my part-time job at the Canadian Tire gas bar, I had occasion to assist a customer change the headlight bulbs in his vehicle.

OK, you say, we all do that at one time or another. Well that may be true, but this instance bears mentioning.

Let’s say, for sake of simplicity, that my assistance consisted mainly of holding my little LED flashlight so he could do the actual changing.

The vehicle in question was a 2002 Honda Pilot. The instructions were quite simple.

1. Disconnect the 3-pin connector from the base of the bulb.

2. Remove the rubber seal from around the housing.

3. Release a wire clip holding the bulb in place and carefully remove the bulb.

4. Reverse all procedures to install new bulb.

Quite simple EH?

By comparison I drive a 2006 Pontiac Montana. Now changing the headlight bulb is a lesson in futility.

1. Remove screw holding housing to frame.

2. Turn 90 deg metal post 1/4 turn clockwise. This will allow removal of the entire housing. Entire housing you say? Yup. This is not the easiest chore in the world, especially if said housing snags as mine did recently. I had to force it to release and was afraid I was going to break it. Luckily it came out, b ut then was difficult to return to its place.

3. Turn bulb and socket 1/8 turn clockwise.

4. Disconnect wiring harness.

5. Remove bulb.

6. Reverse all steps to install new bulb.

Not so easy is it?

Now my third example is my former vehicle, a 1996 Ford Crown Victoria. A model of simplicity.

1. Open hood.

2. Remove 1 screw, thus allowing removal of protector.

3. Disconnect wiring harness from bulb. Turn bulb 1/8 turn counter clockwise and remove.

4. Reverse all steps to install new bulb.

My point is this. If Japanese engineers can design such a simplified way of doing things, and Ford engineers used to do it, then why not GM? For that matter, why not all car manufacturers? Changing a bulb should not require the use of any tools beyond those which God equipped us with, namely our hands.

Don’t even get me started on getting the doughnut spare out from underneath the van. Why is there not provision either under the rear seats in a minivan or pickup truck, or on a bracket on the lift gate, as most SUV’s have? Nope, you have to use the jack handle to turn a sprocket arrangement which is supposed (?) to lower the spare from under the vehicle. I say supposed, because after a few years of being constantly sprayed with water, road salt and debris, this sucker ain’t gonna move. Nothing like crawling under a van at 2:00 am in the pouring rain to get the damn thing. One reason I have CAA. Let someone better equipped do the crawling. I can work a jack fine, and removing a wheel is no biggie either, but getting that damn doughnut out from under is a pain in the you-know-what. Now I carry the spare inside the vehicle directly behind my wife’s seat. We have a pet barricade in it, and the spare is sandwiched between the seat and the barricade.

CH-CH-CH-CHANGES

25 Sep

There are some new things on the horizon for my XYL and I. We have purchased a 1/2 acre building lot on the outskirts of a small village nearby and plan on building a new abode next summer. That is, providing our current house is sold. The new house will be slightly smaller than the current one and will also have a 1-1/2 car garage. Personally I can’t figure out where the term one and a half car comes from. I certainly have never seen 1/2 a car. What good would it be? Would it have two wheels? Which half of the engine would you get? To me that almost hints on being a motorcycle.

Anyhow that is the plan. MY previous plan of selling out and moving to the east coast has been shelved, primarily because my XYL firmly stated that she would rather become a nun  than move “down there”. After all the dampness bothers her here. What would it be like for her near the ocean where the dampness is always prevalent? I doubt she would be conducive to waking up many mornings to see heavy fog until noon.

In the garage would be my shack and shop. Directly behind the garage I plan on planting my 64 foot steel tree. Finally, after over 50 years as a ham I am finally going to get my own steel tree aka tower. With a real beam atop it no less. Will wonders never cease? I may even get myself an amplifier so I can send even more RF into the atmosphere!!! The idea is almost mind boggling. I get to spend the remaining years of my life running TCC skeds on 20 meters, and maybe even some serious DX’ing.

As always, time will tell. Convincing my wife that I really need this amp will be no easy thing. I had a difficult enough time convincing her to let me buy my second rig. And despite it being my own hard earned money by way of a tax refund too!! Imagine using a shred of the proceeds from the house sale for another “radio”? Sacrilege I say – sacrilege.

The Morse Telegraph Club – A Brief History of How Morse Evolved

31 Aug
The Morse Telegraph Club
By James Wades, WB8SIW
Few today realize that the telegraph was still used in commercial service in North America well into the mid 1980s. While many of the last users were railroads, the telegraph was also used in a wide variety of business applications by organizations such as stock brokerages, commodities exchanges, pipeline companies, news wire services (Associated Press, United Press, etc.) and the like. For example, the Chicago Board of Trade utilized telegraphy until 1972 and some stock brokerages were still using telegraphy as late as the early 1980s! Even the Telephone Company maintained an extensive telegraph infrastructure for decades because telegraph circuits could be composited (superimposed) on long – distance voice circuits allowing the latter to remain in revenue service while
internal company business and leased private wire services operated in the background using telegraphy!
 
Before the advent of Microwave Carrier Systems and new telephone technologies in the 1960s, many sporting events were recreated at the local broadcast station. The play – by – play was transmitted by telegraph and then  translated into live action by a radio announcer at home. For example, “S1C” became “Strike One Called ” or “NBF” became “now batting for.” Few today realize that one can often telegraph baseball play – by – play faster than one can “speak it!” Contrary to popular belief, and in contrast to many poorly written historical accounts, telegraphy
was not replaced by the telephone. Rather, the modern – day Internet is largely a natural evolution from telegraph technology. For the first one hundred years of telephony, telegraphy offered many advantages over the telephone. One important advantage was more efficient use of infrastructure. Over time, the telegraph evolved from one circuit on a single wire (simplex) to two circuits on a single wire (duplex), then four circuits on a wire (quadruplex)
. With the emergence of stable vacuum tube oscillators during the 1920s, carrier systems  were developed, which allowed multiple telegraph circuits to be conveyed on a single pair . This led to concentrator systems (“varioplex”), automatic switching centers and then….packet switching. In reality, no one person “invented ” the Internet.
Rather, the Internet was an important, but nonetheless incremental improvement in the field of telegraphy. For much of this period of evolution a small army of men and women employed by companies such as AT&T, Postal Telegraph, Western Union, Canadian National Telegraphs, Canadian Pacific Telegraphs and the like kept this complex , world-wide network functioning smoothly , and for a significant number of these men and women, knowledge of the American Morse Code was a requirement for their job.
 Many of the men and women who worked in the telegraph industry or related fields are now members of the Morse Telegraph Club (MTC). The MTC is an association of retired railroad and commercial telegraph operators, former telegraph industry employees, historians, maritime radio operators, radio amateurs and others who share an interest in the history of telegraphy and the telegraph industry. In addition to “members at large,” MTC has numerous Chapters throughout the United States and Canada. MTC publishes a Quarterly Journal entitled “Dots and Dashes,
containing club news and various historical articles. Members present talks on the history of telegraphy and
telecommunications for clubs, historical associations, engineering societies and the like. Our Chapters actively demonstrate telegraphy at steam train excursions, Civil War re-enactments, and  similar historical events. MTC also designs and builds historically correct telegraph exhibits for  public museums throughout North America. Many of the instruments for these museum projects  are provided by MTC. One need not be a former telegrapher to join MTC. All that is required to join 
is a sincere interest in the history of the telegraph and the telegraph industry. It is also important to know that MTC is
not just another ham radio “CW” organization. There are many fine groups that already promote CW and it makes no sense to add another. Rather, MTC concentrates on the Telegraph and the American Morse Code. The American Morse Code is the original code developed by Morse and Vail. It contains a number of spaced characters, such as “C,” “O,” “R,” “Y,” and “Z.” The letters “T,” “L,” and the numeral zero are each a single dash, but of differing length! Furthermore, some of the letters have alternate dot – dash combinations, such as “F” and “J.” When the first  undersea cables were deployed, telegraph engineers quickly learned that signal distortions made it impractical to use on-off keying. A new method for undersea telegraphy was required, which used a shift in polarity to differentiate between “dots” and “dashes.” As a result, it became necessary to replace the spaced characters and three different “dash” lengths in the original American Morse Code. Therefore, a Committee met in Europe, which adopted a new code called the “Continental Code.” Today, this code is commonly referred to as “International Morse.” It is this code
which is used by radio amateurs.
 The Continental Code was quickly adopted as the world – wide standard for telegraphy. However, in the United States and Canada, the older American Morse Code was already well established. It was not practical to retrain the tens of thousands of operators already employed in the telegraph industry. Furthermore, the American Morse Code is approximately 20 to 30 – percent faster than the Continental Code, thereby offering some economic advantages. The result was an interesting dichotomy in the field of telegraphy. In North America, commercial and railroad  telegraphy continued to use the American Morse Code. However, when Wireless Telegraphy became standardized, the International Code was adopted 
 Of course, the history of “Morse Code” is quite nuanced. At different times, there have been up to four different “Morse Codes” used in North America including the “Bain Code” and the short – lived “Navy Code” used briefly during the early wireless era. Adding confusion to the historical record is the fact that Great Lakes shipping used the American Morse Code for a bit over a decade before International standards were adopted in 1912. The result was, of course, cross – pollination between commercial telegraphy and wireless telegraphy. Consider these examples:
 The prosign “AR” (“di-dah-di-dah-dit”) is really the abbreviation “FN” (“finished”) in the American Morse Code.The
prosign “SK” (“di-di-di-dah-di-dah”) is really “30” in the American Morse Code, “30” meaning “close of work” in
Western Union and Press Telegraph Shorthand. and still used in a number of textual publications including Solid Copy! (Note: Solid Copy is the monthly publication of the CWOPS club of which this blogger is a life member.The  “ES” (“dit di – di – dit”) heard on the ham bands is the “&” (ampersand) in American Morse Code….and so forth.

ARRL Centennial Radiograms Announcement

Going on Hiatus

29 Jun

As of Tuesday July 1, I will be taking a two-month (approximate) hiatus from all things radio. That means that I will also not be posting to this blog. I will not be generating any traffic. I will not be in any contests or nets. My shack is being torn apart and rebuilt in a more compact layout. I hope to have all new antennas up in the air by September including beams for HF and 2 meters. I aim to utilize a multiband wire antenna covering the 160, 80, 40, 30, 18, and 12 meter bands. 20, 15 and 10 will be handled by my tribander. How high the tribander will be mounted remains to be determined, but I expect it to be either 40 or 48 feet. 40 feet if attached to the fascia of the carport and 48 feet if mounted on a concrete base. My 2 meter beam will be at 60 feet and my wire antennas will be attached near the top of this tower.

  Of course all of this planning depends on several factors. One of these is the completion of several items on the  honey do list. Another is the availability of funds to complete the project. Another is my own health. I am not as capable of running around on the roof of the house, nor climbing towers as I once was. I will have to rely on others for these tasks now. Oh well we shall see.
