Disappointing Email from ARRL

A few years back I took the best online course and today I have found nothing that compares. It was an ARRL propagation course it involved interaction with a mentor who was assigned to you. It had fantastic course material, as well as hands on projects. Before enrolling  propagation  was like a foreign language to me. By the end of the course with the help from the mentor, course material and the reviews I began to fully understand how important propagation was and also understood terms such as CME, A and K index, Flux, Solar wind and so on. I was able to put it all together and make sense of things when it came to ham radio and propagation. To this day I still refer to the notes and course materials to clarify things. There were many online course's that were offered. Some courses that still interested me were antenna modeling and RFI....so it was off to the ARRL site to find it. The only coarse's that was offered were public service and emergency communications. I emailed the ARRL asking if any of the other courses were available below was my reply.
Hi Mike,
 
You are correct-- we now offer only emcomm courses online.  
We had to take down our old online course platform and 
have not re-invested in redeveloping the other courses 
to re-launch them on the new platform.
 
However, we are looking at ways to re purpose the content 
from those courses. The first effort is to publish 
an "Introduction to Antenna Modeling" course book 
utilizing the material from the course you mention.

 It seems to me that  a "course book" is the new online course replacement when (and if) it comes out. The propagation course formate was very good and can't be replaced with a book. Seems to me the online learning was just not a priority when the ARRL web platform was revamped......well I'm one disappointed ARRL member.

I’m Struck…

…by the thing that most people are struck with nowadays: noise. With the wife on a business trip and I having to take care of the kids there was little time to spend in the shack last week. But when I did turn on the radio last weekend I was met by an S3 to S6 noise floor. And I thought moving out into the country would prevent me from suffering something like this. Alas, I moved to “gridlock” county, with grid being the power grid. Taoyuan county is full of high voltage power lines coming from the south and going to the capital Taipei in the north. The noise sounds a lot like RF noise generated by arcing power lines and I have seen defective insulators before in the area. I took my (t)rusty ATS-909 for a walk on Monday night and the whole neighbourhood is suffering. I haven’t located the source yet, but I will. In the mean time I’m QRT as the noise is so intense that I can’t stand it for even a couple of minutes.

Now while this whole noise problem is something most people will be upset/angry/disappointed/frustrated/depressed about, nowadays I take the Buddhist approach: don’t long for things that aren’t there, but see opportunities in the things that are in front of you. (I know, not really a Buddhist saying, but one I made up myself. It does reflect the spirit, though). Just like KD0BIK with his unfinished dummy loads I started counting my unfinished projects: 2 BiTX transceivers, a variable power supply, my TS-440S with the dots problem, an AA0ZZ keyer, the VFO for my Pixies, a cloud temp sensor and a home brew Buddipole. Not to mention the antenna’s I still have to erect for 2m/70cm and NOAA-APT reception. Oh yes, my 1-wire weather station is also still packed up, waiting to be installed. Being QRT might just be the push to get my house in order and get something “really” done. By the time I am done the noise will probably have disappeared, too. I’ll see you in a bit.

Handiham World for 28 September 2011

Welcome to Handiham World.

What got you started in radio?

When I think about that question, I recall a little crystal radio kit that my dad bought for me.  It had a plastic housing to make it look like a real table radio, except that it was smaller and had only a single earpiece.  And of course it “magically” took a radio signal right out of the airwaves and turned it into music without any electricity at all!  It was one of several crystal diode radios that I had as a kid.  Another memorable one was made up in a round plastic ball that was supposed to be a satellite.  There was a tuning control that consisted of a slug-tuned coil. The brass screw from the ferrite slug extended out of the top of the “satellite” like some sort of antenna.  It had a little rubber cap on it to serve as a grip, so that the coil could be tuned more easily.  The real antenna was a piece of bell wire with an alligator clip at the end.  That allowed you to connect the radio to something conductive that might hopefully act as a better antenna and bring in a local AM station.  Of course today the term “satellite radio” means something completely different!

When I was a teenager, dad bought me a Knight-Kit Span Master two tube regenerative receiver.  It was not my brightest moment in radio when the kit manual called for putting “spaghetti” over some of the bare wire leads during assembly and I went down to the kitchen cabinet to find this apparently necessary but odd ingredient for a radio.  Dad straightened me out on that and we ended up using the insulating tubing that was actually already provided by Knight-Kit.

Image:  Here is the Knight-Kit Span Master as shown in a 1962 Allied Radio catalog.  You could get the outdoor antenna kit for only 1 cent more, but the radio itself cost $25.95. 
The Span Master worked when it was finished, so I installed it in the vinyl-covered wooden cabinet that came with it and ran a wire out of my bedroom window to serve as an antenna.  The circuit might not seem like much, since it had only two vacuum tubes, but it turned out to be light-years ahead of the crystal radios.  One important feature was a speaker, so I didn’t have to use headphones.  The tuning knob was connected directly to a variable capacitor, but there was a helpful bandspread knob connected to a second capacitor so that fine tuning was possible without pulleys and dial strings.  Furthermore, the radio had a band switch and covered not only the AM broadcast band but also several short-wave bands.  In spite of the two tube design, a fair amount of gain could be had from the simple regenerative circuit.  It was also possible to hear Morse code and even something that was new and mysterious back then:  SSB. You had to be patient and careful tuning it in, though.  It was more fun to listen to far off short-wave stations and find out what was happening all around the world.

I consider the Span Master to have been the radio that really got me interested in getting my amateur radio Novice license.  Today we can still find electronic kits, and who knows?  One of those kits might spark the interest of a future engineer, scientist, or teacher!  Consider an electronic kit as a gift for your child, making it age-appropriate, of course.  Then make it a parent-child project to assemble it and make it work. You will both have fun, and open the door to STEM:  Science, Technology, Engineering, and Math.  

Next week: Thoughts about a broken water pipe. 
For Handiham World, I’m…

CQ to add digital editions to all magazine titles

As first reported on the Southgate site:

CQ Communications, Inc., will launch multi-platform digital editions of all of its magazine titles before the end of 2011, Publisher Richard Ross, K2MGA, announced today.

Those titles include CQ Amateur Radio (CQ magazine), CQ VHF, Popular Communications and WorldRadio Online. Many CQ book titles are already available in digital form on CD.

“The digital editions will supplement, not replace, current print editions, and will feature enhancements not possible in the print medium,” said Editorial Director Rich Moseson, W2VU.

“Versions will be available for a variety of online and mobile platforms* and will be hosted by Zinio, one of the top names in the e-magazine hosting business. This will assure that our magazines will always be able to take advantage of new technology when it becomes available.”

Examples of features that will be possible in the digital editions include live links to all World Wide Web addresses listed in each issue, as well as supplemental content, such as photo albums, audio and video files, software and more. “Imagine reading an article about meteor scatter and being able to listen to a meteor scatter contact with a click of a mouse,” said Moseson, “or reading an ad for a piece of new gear and being able to click directly to a video explaining its features. All of this and more will be possible in our digital editions.”

“At the same time,” he added, “the print editions will retain their unique characteristics, such as portability, the tactile experience of holding a magazine in your hands, no need for batteries and the ability to continue reading on an airplane after you’ve been told to turn off all electronic devices!”

The digital launch will begin in late October with the November issue of an enhanced, multi-platform, version of WorldRadio Online, which will again become a paid-subscription publication; followed by November CQ, which, appropriately, is the magazine’s first annual Technology Special. The fall issue of CQ VHF and the December issue of Popular Communications will round out the introductions. Digital editions will be available by single copy and by subscription.

Details will be in the near future in the magazines and on all CQ Communications websites.

(*Initially, digital editions will be compatible with the following platforms:
PC, Mac, iPhone, iPad, Android 2.0 and higher.)

In light of the recent discussions here about World Radio going digital, is anyone surprised?  I remember when one of my favorite titles, PC Magazine, went to Zinio.  I tried it but could never get used to it.  Then, awhile later, they discontinued their print version. I never read another issue.

CQ Communications has seemed to embrace the “walled garden” of their print magazine instead of publishing articles on their website. This is an understandable business decision, but I think that they’ve missed an opportunity to build their online brands in trying to protect their paper magazines. Again, not sure that I’d do it differently. But looking at PC Magazine’s website, it seems that most content is now available free online. Granted, some will enjoy the magazine-like interface that Zinio offers, with their animated page turns, etc.

One line from this press release struck me as kind of funny:

Examples of features that will be possible in the digital editions include live links to all World Wide Web addresses listed in each issue, as well as supplemental content, such as photo albums, audio and video files, software and more.

Photo albums? Audio and video files? Live links to World Wide Web addresses?  These sound like cutting edge features. In 1996.  It has to be more than this to get people’s attention — and money.

The folks at CQ may have no choice but to start the process of moving to digital distribution with the magazine publishing business being as it is.  I desperately want to see this effort succeed.  We can’t afford to lose another great magazine.  CQ is smart to keep its print editions, at least for now.  But I believe that most hams will not pay for a digital-only magazine — at least not yet.  I hope I’m wrong.

Ten-Tec at Hunstville Hamfest

Someone from the Short Mountain Repeater Club, made a nice video from the Huntsville hamfest. It shows Ten Tec‘s booth all setup and looking sharp. It’s a short video but by all means it still is nice to get a look at hamfests from other parts of the country.There’s not much to tell about this. It’s just a look at the booth and all the great radios TenTec makes. Short and sweet. Enjoy.

Yet another fake Diamond antenna

I ordered a Nagoya NA-771 antenna on eBay. I was impressed with the shorter NA-701 and wanted something with a bit more gain that was not poke-you-in-the-eye long. The NA-771 had mostly good reviews on eHam.

I ordered from an eBay seller that shipped from the UK. The price was £4.99. When it arrived, I found the packaging and the antenna itself claimed to be a Diamond RH-771 not a Nagoya NA-771.

But this is clearly another fake Diamond. The lettering is white whereas the real Diamond product is lettered in blue. The lettering also contains nonsense. It claims “144/430 MHz & VDE BAND HECEMNG COVERAGE JAPAN.” Eh??? Perhaps it was supposed to say wide band general coverage? And the antenna is only 36cm long whereas the real RH-771 (and the NA-771) are supposed to be 39-40cm long.

None of this would matter if the antenna was any use, but in fact its resonant frequency is just below 120MHz. At 145MHz the SWR is more than 4 to 1 and it radiates a poorer signal than the shorter Nagoya NA-701 antenna.

Anyone want an air band antenna? Yours for a fiver. And can anyone recommend a seller that has the genuine Nagoya NA-771?
