Digital Bling and a Cautionary Tale

The news this week about QST going digital is exciting stuff. (See the next story for an explanation and link.)  If our own Handiham World had not gone digital, we would still be publishing only four issues a year, one for each season.  Yes, back in the bad old days a couple of decades ago the Handiham World was mailed out each Spring, Summer, Autumn, and Winter in a print format.  Volunteers would read the print version onto cassette tapes that were mailed to our blind members. Any news that arrived via that system was bound to be pretty old.  Then, when printing and mailing costs began to climb we had to cut down to three issues, then two.  Using the Internet to deliver the Handiham World was faster, cheaper, and better.  Not only could it be read directly with screenreading software by our blind members, but it could be in audio as well, also delivered via streaming or download. Members could even call a phone number to hear the same Internet audio, even if they only had a telephone. The Handiham World could be enjoyed by anyone as a podcast from iTunes.  Better yet, it could be published weekly instead of quarterly.  
Even though these advantages seem obvious, there were – and still are – some who feel that our service has left them behind.  These are the members who don’t have computers and who don’t plan to get them.  And this, my friends, is the problem every publisher faces.  That is why I’m going to share with you my experience with a newspaper. 
It is certainly not news that newspapers want to print:  Newspapers are struggling to find their new business model in the 21st century. Who reads them anymore?  
Probably people like me, that’s who!  I’m old enough to remember having a paper route as a kid.  Delivering the daily paper was one of those rite of passage jobs a kid could have back in the middle of the 20th century. The news business was less competitive back then, and there was little urgency to have up to the second updates.  The newspaper business held its own until cable news began nipping at its heels, but it wasn’t until news sites began appearing on the Internet that the real problems with printing paper copies and physically dumping them on doorsteps became too big to ignore.
These days we would get our newspaper delivered by some guy driving his personal vehicle around town and pitching the paper out onto the driveway or sidewalk.  He would back over the lawn and sometimes his truck would have a loud muffler in the wee hours of the morning. Often as not the morning dew or the lawn sprinklers would soak the paper before we could retrieve it. On rainy mornings the paper arrived in a plastic bag that managed to protect about 3/4 of the paper from getting soaked.  The newspaper company also published an on line edition once the power of the web was obvious, and like many other readers I took to it instantly and never looked back.  Unfortunately for the newspaper, they lost money giving the news away for free on the web (duh), and they finally had to come up with a pay-for alternative.  It involved a special digital edition that looked just like the printed version.  In a scattergun approach to pleasing every customer from the grumpiest computer-hating Luddite to the early-adopter geek, they offered a plan to give you a print paper AND a digital edition.
We signed up.  I like trying new stuff but I still like a print edition.  This would be a chance to compare the technologies.  
It’s been a couple of months now, so I feel as if I know where things are going.  Both my wife and I read the print paper to some extent, and both of us use the newspaper’s website.  The website is actually easy to use, but it is not the new so-called “digital edition” that looks exactly like the printed paper.  For that, you have to log on to a special website. The newspaper sends a helpful link by email each day as a reminder.  The digital look alike loads a web application in your browser window, after which you see the copy of the printed version in what amounts to a browser frame.  Try as I might, I just cannot warm to the idea of trying to read a newspaper that way.  The page does not all fit in the browser window, which means that you are constantly scrolling one way of another to read articles.  Worse yet, because the digital look alike is supposed to be like the printed copy, you have to follow the story onto other pages buried deep in that day’s edition.  The pages of the digital edition have a feature that prompts you with a cute little animation to turn them.  Page turns themselves are also animated.  Ooooo!  This is digital bling!  It looks so cool, but let’s face it – I think having to scroll left and right and up and down, then fiddle with the mouse to get the cursor exactly in the right spot to connect me to the remainder of a front-page article that ends up buried on page 10 is just not my cup of tea.  What I want is content.  I would like it to be easy to find, easy to read, and – after being in the business of helping people with disabilities for so many years – accessible to people who use screenreaders. I have to say that some of these new digital publishing efforts fall flat on all those counts.  
What I don’t really understand is the need to make a digital edition look like a printed page.  The printed page is fine when it is a printed page.  When it is a digital copy on a small screen, it is like putting Victorian furniture in a Frank Lloyd Wright house. It is a bad fit. If you are going to use the web to publish your newspaper, publish it using the easily understood, common, and highly accessible web page formats that are already available. That is why for Handiham World we provide accessible HTML in our web pages.  If we put something up in a format like PDF, it contains embedded text and an audio alternative, plus an HTML version.  But really, the PDF version is not meant so much to be read on line as to be printed and read as a print publication.  
The bottom line with digital publishing is that it needs to be recognized for what it really is – a new and better way to deliver content that is more up to date, cheaper to deliver, and takes advantage of the technology to allow users to search thousands of pages quickly, have access to past issues without collecting an attic full of paper copies, and enjoy it all with accessible technology.  It is not a new way to deliver the same old paper dressed up with page turn animations.  In other words, forget the bling and give me the content.  
Oh, well.  At least the digital version does not drive over my lawn at 4:00 A.M. in a noisy truck.  On the down side, I miss the plastic bag that is so handy for “dog duty” when I take Jasper out for a walk.

Humans have always had a desire to communicate. They started out just talking to each other but then found that it was really handy to be able to write things down. This caused the invention of the alphabet and the training of English teachers to explain overly-convoluted rules of grammar.

In 1831, Joseph Henry was playing around with electric circuits and came up with the idea of a telegraph. We can imagine a simple system where ON means “time for dinner” and OFF means “not yet”. This wasn’t good enough for Samuel Morse, who invented the Morse Code which could use ON and OFF to represent the entire alphabet. This was the first digital code and was used for important messages such as “Laughing Out Loud”, later abbreviated to LOL. This was basically the same as modern text messaging but you needed a trained telegrapher to do it.

In 1875, an inventor named Bell decided that it would be better if you could just talk over the wires instead of messing around with Morse Code. This will be a recurring theme — whether to talk to other people or just send digital codes. Bell invented this thing called the telephone, which is still used today. Basically, a person could talk into one end of a wire and have his voice pop out of the other end.

Later a guy named Marconi came along with the idea that communication should not depend on wires. For example, it was quite inconvenient to drag a telephone wire behind a ship as it moved across the sea. Unfortunately, Marconi didn’t know how to do voice over the wireless, so he dropped back to using Morse Code. ON and OFF is a much easier way to go. Although there is a persistent rumor that Marconi intentionally used Morse Code to torment future generations of FCC Licensed Amateur Radio Operators, I can find no evidence of this. Some people argue that Nikola Tesla invented wireless but I think he had to be disqualified for overloading and shutting down the Colorado Springs power grid on numerous occasions.

Again, not wanting to be limited by trained telegraphers, voice communication (originally called Amplitude Modulation, but now known as Ancient Modulation) was invented. We are not sure who first came up with Ancient Modulation, but there are a bunch of radio hams on 75 Meters still trying to perfect it.

Somewhere around 1973, Motorola figured out that what the world really wanted was a portable phone that everyone could carry around in their pocket. The first attempt at this was the Motorola DynaTAC, which required an enormous pocket to carry it in. Knowing that customers were not going to enlarge their pockets, various mobile phone manufacturers worked feverishly to reduce the size of these phones.

Unfortunately, the mobile phone manufacturers terribly miscalculated, thinking that people would want to actually talk on these phones. As text messaging was added to these phones, it was discovered that most people, especially those under the age of 30, preferred to send cryptic text messages rather than actually talk to anyone. It was also discovered that all forms of human thought can be captured as 140 character messages. Although it was tempting to apply Morse Code to digital text messaging, it was rejected in favor of the ASCII 8-bit code. Instead of using ON/OFF keying, text messages are normally sent with a tiny keyboard patterned after a full-size typewriter (now obsolete).

P.S. I made up some of this stuff.

An interesting article appeared on physorg.com yesterday regarding changes in the Earth’s magnetic field and its relation to solar activity. Although short on detail it hints at significant changes going on within our sun.

Since the mid-1800s, scientists have been systematically measuring changes in the Earth’s magnetic field and the occurrence of geomagnetic activity. Such long- term investigation has uncovered a number of cyclical changes, including a signal associated with 27-day solar rotation.

This is most clearly seen during the declining phase and minimum of each 11-year solar cycle, when the Sun’s magnetic dipole is sometimes tilted with respect to the Sun’s rotational axis. With the Sun’s rotation and the emission of solar wind along field lines from either end of the solar magnetic dipole, an outward propagating spiral-like pattern is formed in the solar wind and the interplanetary magnetic field that can drive 27-day, and occasionally 13.5-day, recurrent geomagnetic activity.

Recurrent geomagnetic activity can also be driven by isolated and semipersistent coronal holes, from which concentrated streams of solar wind can be emitted.

During the most recent solar minimum, which took place from 2006 to 2010, however, several researcher groups noticed 6.7-day and 9-day recurrent changes in geomagnetic activity, and similar patterns in the interplanetary magnetic field, and the solar wind. Using modern data covering the previous two solar minima, these higher-frequency occurrences were judged to be unusual.

Love et al. analyzed historical geomagnetic activity records from 1868 to 2011 and find that the 6.7-day and 9-day recurrent changes were actually unique in the past 140 years.They suggest that the higher-frequency changes in geomagnetic activity are due to an unusual transient asymmetry in the solar dynamo, the turbulent, rotating plasma deep within the sun which generates the magnetic field.

Exultate Festival Choir and Orchestra Performing Handel’s Messiah at Benson Great Hall, Arden Hills, MN on 03/11/12.

What a week and a half it’s been! Last weekend we sang three performances of Handel’s Messiah. The last one, pictured here, was the best — truly out of this world.

NØIP walking near the Duluth Lift Bridge, 03/13/12.

Afterward, without even changing out of my suit, I drove to Duluth with my wife to stay in a bed and breakfast for a couple nights. It wasn’t purely vacation; since this is a busy week for me, I did have to get some work done on this trip. Still, it was sufficient to give me newfound vigor upon my return. A day and a half back in Granite Falls allowed me to do some calling and get some other work done, and then it was back to the Twin Cities for two recording sessions to make a 3-CD set of Handel’s Messiah.

Wouxun KG-UV6D Dual-Band Radio

During this time I tested out my new handheld, which arrived just a couple days before it all began. I went with the dual-band (2m/70cm) Wouxun KG-UV6D (ham radio version), available here. If you buy one of these you’ll want to purchase the USB programming cable to set up your Wouxun using your computer. You may also want to buy an adapter or two to connect antennas to it. I’ve included some photographs in the slideshow below showing two such adapters — one for BNC, the other for PL-259. (By the way, you may click here to learn how you pronounce “Wouxun.”)

This radio is working great! Setting up channels using my laptop was a snap, and the controls on the radio itself are pretty simple, too. Using a larger “rubber duckie” antenna I’m able to hit the repeater 12 miles away in Montevideo (though I’m not sure yet how I sound “You sound like you’re sitting right next to me,” I’ve just been told.). Using the car-top antenna I’m full-quieting on the repeater 30 miles away in Marshall, and I can hit the repeaters a little farther away in Willmar, too (though I’m not sure yet how I sound on them). I made a few contacts in Duluth and the Twin Cities this week, and heard good reports each time. So far all I’ve used is 2m, and I’m looking forward to a 70cm contact. While I’m still a confirmed HF CW man, I’m glad to finally have a VHF/UHF handheld that works! If and when my son gets his Technician license, I’ve promised him that I’ll buy him a matching Wouxun KG-UV6D. It would really come in handy around here for him and I to each have one of these.

Welcome to Handiham World.

Last week I was thinking about mentioning something about “bad apples” – amateur radio operators who exhibit poor operating practices while on the air. There was plenty of other stuff to cover in the newsletter and podcast already, so I decided to let it go until this week. Anyway, as you know, the Amateur Radio Service is largely self-policed. That means that we observe what is going on on the bands and help other operators learn good operating practices, largely leading by example.  In fact, the last thing you want to be is “the band police”, which is someone who sticks their nose into every situation and scolds other operators for real or imagined infractions on the bands. No, it is better to lead by example and always use your call sign, be helpful rather than judgmental as much as possible, and convey your concerns off the air. Frequently the telephone is a better choice, as would be a note in the mail. You don’t want to embarrass someone who has made a mistake by pointing it out on the air. If the violation was willful, it is likely that confronting someone on the air about it will simply result in an on the air argument that will certainly be heard by others and show amateur radio in general in a bad light.
Thankfully there are volunteers who listen on the bands for situations that call for some kind of resolution. These are “Official Observers”, or “OO’s”. The Official Observer program is run by ARRL.  It is administered by the Section Manager, and the volunteers report to him or her.  An Official Observer is recommended for appointment by the ARRL Section Manager and completes a short training course by reading relevant information provided by ARRL. For a complete list of the requirements, visit the ARRL website and put “Official Observer” in the search box. You’ll find a complete description and everything you need to know about becoming eligible for this important volunteer appointment.
But anyone can hear a violation or instance of bad operating on the air and take some notes. You can always send your Section Manager an e-mail expressing your concern and asking that Official Observers listen for further violations. Some of the most annoying and difficult situations are those where the bad operating practices go on day after day, week after week, and month after month. These are not something for an individual to tackle; it takes a team to gather information and make a case against the perpetrator. You will definitely want to pass the information on through the right channels. In some cases, the bad operating may be originating outside the borders of your country. Again, going through the right channels to gain experienced assistance is key to solving such problems. That is why I like the Official Observer program.  It is backed by 85 years of collective experience at ARRL in dealing with virtually every kind of technical problem and bad operating practice.
Part of knowing when to report a violation is simply something that comes to you by gaining experience through years of operating and listening on the bands. You learn to get a sense of when something is a willful violation (done on purpose with a bad intent) or simply an innocent mistake that is unlikely to be repeated once the person finds out what they did wrong.  Frankly, all of us are human and will make mistakes. It is not necessary to jump on someone because they made one of these all too common errors. Who among us has not gotten Echolink stuck in transmit mode? Yes, it is an embarrassing mistake but it is not the end of the world. On the other hand, talking for a half-hour in a roundtable conversation without using your call sign even once is not only against the law but also rude and inconsiderate of other operators. As I said, figuring out what to report and what to simply set aside for the moment is one of those things one picks up by experience. Listening is really important in amateur radio. We all learn a lot more by listening than by talking no matter what the situation – and amateur radio is no different!
The ultimate goal is to make the amateur radio bands a better, safer, and more civil place for all users and to always “put our best foot forward” for any listeners out there who might be thinking about getting their amateur radio licenses.

Understanding HF propagation

Along the lines of my previous comments about bad operating practices, I recently received an email about an interference problem on 160 meters.  The interference situation arises when a group of stations in the eastern United States run high power and operate close to another frequency several kilohertz away that is in use by a group of operators here in Minnesota. As you know, these groups of stations may not even hear each other during early evening hours when daytime conditions hold sway and absorption keeps long-distance sky wave propagation from taking place.  As the night falls and the ionospheric absorption decreases, the band starts to open up to longer distance skip, and soon the two groups of stations begin hearing each other.  
Both groups may be tempted to dig in their heels and say, “We were here first”, but the fact of the matter is that the propagation conditions simply changed and that is what causes the interference. Understanding that it is not the other guy’s fault is important in making a decision about what to do next.  
Remember what the FCC says about how we should only use the level of power necessary to carry on communications?  Well, Sec. 97.313 Transmitter power standards, (a) says, “An amateur station must use the minimum transmitter power necessary to carry out the desired communications.”
When propagation conditions change, there are three good choices to mitigate the interference problem:

1. All stations in both groups should lower their transmitting power levels, even though the temptation is to crank up the linear amplifier.  Lower power levels decrease the likelihood of interference.
2. Consider using a different frequency.  This is often the best solution.  Remember, no frequency has any single user’s name on it – I don’t care if your group has been on “their” frequency for 10 years.  Get out of the mindset that one can claim a frequency by squatter’s rights.  
3. Change the scheduled time of your on the air gathering to avoid the propagation conditions you find undesirable.  

Notice that these are all non-confrontational solutions that do not involve blaming “the other guy”.  Understanding HF propagation can be very helpful in solving interference problems and enjoying ham radio even more!

Troubleshooting 101

If you are like most amateur radio operators, you probably have several portable, battery-operated devices that take consumer-grade replaceable cells such as AA’s or 9 V square batteries often used in smoke detectors. In this scenario, you decide to use your dip oscillator to check on the approximate resonant point of an antenna that you are building. When you press the power button, nothing happens. Since the dip oscillator is a battery-operated portable device, the first thing you are probably going to think of doing is checking the battery or batteries. For some incomprehensible reason, many of these amateur radio test accessories require you to use a screwdriver and take the case apart to get at the batteries. This makes it inconvenient to take the batteries out if the device if it is not going to be used for a long period of time.
Okay, so you go ahead and get the screwdriver and take the case off the dip oscillator. What do you see? Of course the battery is dead; it has obviously died a rather messy death because there is a white residue around the contacts. The battery has leaked and corrosion may have set in, possibly damaging the dip meter. The first thing to do is dispose of the old battery safely. Usually alkaline batteries or the old carbon-zinc batteries can simply be thrown in the trash while  batteries with other chemistries such as rechargeables might have to be taken to a recycling center.  If you are unsure of the residue leaked by the battery, it is prudent to wear gloves. Anything leaked from a lead-acid battery should be considered dangerous and corrosive. Usually such batteries are not found in small accessories.
With the battery gone, you can now attend to the mess left behind inside your meter. Flaky or powdery residue can sometimes be removed effectively with a brush such as an old paintbrush that is dedicated to such projects on your workbench. Do your best to avoid inhaling anything and if necessary use a mask to protect your lungs. A damp Q-tip can also be effective without creating dust. I have used a Q-tip dipped in rubbing alcohol because the alcohol will evaporate from the circuit board and contacts quickly. You don’t need to use much! A pencil eraser like the kind on a number two lead pencil can do a pretty good job of polishing up a battery contact on the meter’s battery holder.  Try to make sure that the battery holder contacts are shiny and clean before putting in a new battery. I always try to avoid using abrasives on these battery contacts because they will remove any plating and open the road to further corrosion. If the battery contacts have been destroyed, it will be necessary to find a new battery holder, and this may mean making some slight modifications to accommodate it. Every case will be different, so this is a chance to be creative and figure out your own solution. Just be careful that nothing will short out when the meter is in use or when you put the case back on!
I have always wondered why manufacturers of these devices make it so doggone hard to get at the batteries in the first place. Something like a dip oscillator will only be used occasionally by most amateur radio operators, so it would be great to be able to put in and remove the battery easily and quickly so that the device could be stored for months or years without the battery in place.
