As the propagation columnist for several amateur radio magazines, I hear from a diverse group of interested people that find space weather and the propagation of radio waves fascinating. I admit: I am a space weather and radio propagation nut, and it is always good to correspond or meet with other interested folks. This is an aspect of our hobby that never grows old, as there is so much that we don’t yet know–we communicators are in a perfect space to make discovery and to make improvements to our understanding of this science.  Over the years, I’ve heard a lot from readers of my columns, expressing their fascination with the science of radio and solar phenomenon.

Are you interested in learning about the Sun and the Sun-Earth connection (space weather), including topics of sunspots, solar flares, coronal mass ejections, and so on?  Do you want to delve deeper into topics including the ionosphere, the magnetosphere, and how radio waves propagate from transmitter to receiver?

The critical frequency (foF2) for mornings during June 2014.

You might consider a time-proven “course”–material that is very comprehensive–that you can self-study, to become well-versed in this information. The course (one that has been used in professional disciplines) is offered either stand-alone, or bundled with the ray-tracing PropLab PRO software. 

Some may say, “But, I like the magic of just getting on the air and trying my luck! If I learn all this stuff, then it becomes science, and not a hobby.” It is true that there’s a joy at being dazzled with the magic of radio; buy a super cool transceiver, and a factory-made antenna with coax already fitted with connectors, adding the necessary accessories to make it come alive, then begin exploring the shortwave frequencies. Magical, indeed! But, there are many in the hobby that wish to learn how all of that works. Some even begin learning how to build antennas, radio kits, and discover the joy of the “science” of radio. A few eventually take the step with gained “scientific” knowledge of electronics, and they design and build equipment for their hobby. The course is part of that mix: learning how the Sun affects getting a radio signal from point A to point B, and how to leverage their time and efforts, is a joy, indeed.

Being from Connecticut I never, really appreciating being that closes the ARRL. I have always had connections from club lunches in Newington as well as being a Diamond Club contributor as I believe in the cause: http://www.arrl.org/the-arrl-diamond-club

I was visiting my dad at the VA in Rocky Hill, which the VA care he is getting right now is amazing and I am excited about that considering all the other news out there. I do not want to get off on a VA tangent, but the story starts there. After a hard day seeing a World War II Vet at 94, I wanted to get back to the airport and head back to Florida. I had some time so I decided to head over the league for a while.

To be on the safe side I emailed the league the night before to ensure they knew I was coming, but I found that over the years of operating it’s pretty easy to get in and of course it’s first come first serve.

Expert Electronics newest radio is the completely autonomous SDR (Software Defined Radio) DUC/DDC. The Russian made SunSDR2 transceiver with the newest ExpertSDR2 software and SDR-control panel E-Coder is going to be introduced at the Ham Radio 2014 in Friedrichshafen in 27 – 29 June. This was first announced at the Mykop 2013 Hamfest for the first time. The concept of Stand Alone or Software Based radios is not new, but this is an interesting step.

This afternoon Tim W3ATB and I went canoeing on the Pemi. It was a perfectly stunning day. I worked Brazil, Italy and France from a small island in the river.

We started out at Profile Falls, a little south of Bristol in my aluminum Grumman canoe. We had a little less than eight miles to go to reach our take-out at Shaw Cove in Sanbornton.

The sounds of red wing black birds clucking from the marshy shore filled the air as we rounded the bend near Hill Village. A pair of ducks took off as we approached and flew south several inches above the water. The old bridge abutment came into view soon after.

The bridge led from Sanbornton to Hill before it was torn down in the 1940s to make way for a flood control area. We started looking for a suitable place to operate. We needed trees, and a breezy place where the mosquitoes couldn’t feed on us. We found it on an island around the next turn in the river.

We pulled the canoe up to the shore and tied it to a log. After jumping out, I tossed a line over an arching maple branch and pulled up a half wave wire for 20 meters.

I sat down on a log, which no doubt landed on the island during spring flooding, and set up the KX3. We had left an hour late and were a bit rushed. At first the band seemed dead, but I found a few strong stations. The first one I called was PV8ADI in Brazil. There was a pileup, and I was surprised when he answered me. We exchanged 599s and I tuned around some more. Here’s my log:

1 Jun-14 2208 14.026 PV8ADI CW 599 599 Brazil
1 Jun-14 2215 14.017 F6FZG CW 579 599 France
1 Jun-14 2222 14.012 IZ4BEZ CW 599 599 Italy
1 Jun-14 2223 14.001 I8GMG CW 559 579 Italy

We clambered back into the canoe and headed downstream for the final leg. The saturated colors of the early evening were dazzling. We started looking for Shaw Cove. It’s just around the next bend, I would say… but it wasn’t.

We found it finally… honestly we were relieved and a bit sad at the same time. We were both long overdue at home… but it was an adventure that will stay with us for a lifetime.

Are you looking for some aids on learning Morse code, or to increase speed and skill? Let’s look at some great information and some software aimed at making your efforts successful.

(Note: I am not associated with any of the software. I just want to help you…)

I encourage you to look at the time-proven Koch method of learning Morse code. Below, we’ll look a little closer at this method of learning and honing your Morse code skill.  In the meantime, if you just wish to skip the details, here are some software links for learning tools using the Koch method:

+ For the PC, I prefer the G4FON Morse code ‘Koch Trainer‘. It is a slick program that is set up to help you learn and enhance your skills with Morse code:  http://nw7us.us/g4fontrainer – and his web site is at: http://www.g4fon.net/

G4FON Koch Trainer – Morse code learning on the PC

+ For the iPad and iPhone: On these devices, I use the ‘Koch Trainer’ by Nick / N3WG, found in the store here: https://itunes.apple.com/us/app/koch-trainer/id405137883?mt=8

+ For the Android: I use the same software as for the iPad and iPhone, the ‘Koch Trainer’ by Nick / N3WG, here: https://play.google.com/store/apps/details?id=com.n3wg.kochtrainer – however, note that it is not compatible on the S4.

+ Some other Android possibilities that I have not tried:

• https://play.google.com/store/apps/details?id=net.iz2uuf.cwkoch
• https://play.google.com/store/apps/details?id=uk.co.bitninja.kmtpro

Again, I have not tried those last few.

Now, let’s talk about the Koch Method of Morse code training!

From my page on the Koch method (text was used by permission from the author):

Koch’s method is a simple, direct way of building reflexes. However, it requires either a computer and Morse software or a personal trainer. That’s why it was overlooked for so many years. Now that computers are commonplace, it should become the standard Morse training method. Here’s how it works:

You start out by setting up your computer (or a microprocessor-based code tutor machine) to send you Morse characters at 20 wpm and at an overall sending speed of at least 15 wpm. You then get out your paper and pencil and have the machine start sending — but only two characters. That’s right, for your first sessions, you’ll only have two choices. Copy on paper for five minutes, then stop the machine and compare what you copied with what the machine sent. Count characters and calculate your percentage of correct copy.

If your score is 90 percent or better — congratulations! You just learned your first two characters, and, importantly, you learned them at full speed. You’ll never have to learn them over again. If you didn’t make 90 percent, practice some more. As soon as you can copy the first two characters with 90 percent accuracy, add a third character to your practice. Your accuracy will drop as you work on assimilating the new character, but it will rise again to 90 percent or better. Then you add the fourth character, and so on.

This method does not allow you to build that lookup table in your brain. To copy at full speed, you must build the reflexes in order to achieve 90 percent accuracy. And that’s what you’re spending your time doing — building reflexes. Think of it as a parallel to perfecting a tennis swing or mastering a gymnastic routine; you’re practicing until you get it right. The Koch method of building code proficiency character-by-character is similar to standard methods of teaching touch typing, another skill that must be reflexive.

…

While the Koch method is the fastest method of Morse training, speed alone is not its principal advantage. Its principal advantage, and a major difference from other methods, is that it provides you with constant positive reinforcement. This begins with your realization, after mastering the first two characters, that you can copy code at 15 or 20 wpm, because you just did it. After that, each new character mastered is further proof of your progress. Contrast that to slowly trying to build speed up from 4 or 5 wpm, then hitting the plateau at 10 wpm and seeing no progress for a long time. With the Koch method, frustration is at a minimum.

Constant testing is necessary to ensure that you maximize the effectiveness of the Koch method. You must copy on paper, so you can grade yourself. Remember, if you score 90 percent accuracy or better, add another character. If you score any less than that, try again. By constantly testing yourself on continuous copying of at least five minutes, you know exactly how you’re doing and exactly when you should add another character. This results in the fastest progress possible.

…

As you proceed toward your goal, remember that some days are just going to be better than others and some characters will take longer to assimilate than others.
