The SunSDR2 and SunSDR-MB1 transceivers – Software Defined Radios?

sunsdr2-mb1_1_smal

 

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.

Canoeing on the Pemigewasset River

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 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.

Learning Morse code? Want to increase your skill?

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:

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.

And, here’s a web-based way to learn Morse code.

Good luck! If you have questions, please share them – I’m @NW7US

Better buy local

My WOUXON KG-UV8D handheld radio with faulty keypad just returned from a quick trip to ML&S. The expierience convinced me of the wisdom of buying Chinese radios from a UK dealer. Within a couple of hours of calling them ML&S had arranged the UPS carrier to collect the radio to take it for an exchange. No making the customer pay return postage (other dealers please note). Next day the radio was on its way back to us. Next day it had arrived. Imagine the trouble I would have returning it to a seller in Hong Kong. No more buying radios on eBay for me!

Upcoming D-Day Special Event Stations

Courtesy of the ARRL:

Several special event stations will be on the air to commemorate the 70th anniversary of D-Day — the Allied invasion of the Normandy Coast of France in World War II.

In France, TM70JUN will be on the air from June 6 — the actual anniversary date — until June 20. Modes will be SSB, CW, PSK, RTTY, and JT65 on HF and 6 meters. Special event station TM70BMC will operate from Mont Canisy June 5-8.

W9D will be active on SSB, CW, and AM on HF through 6 meters June 6-8 from the First Division War Museum in Winfield, Illinois.

VC3JUNO from Canada will be on the air from June 6 until July 31 to commemorate the 70th anniversary of D-Day; “Juno” was the code name for the beach where Canadian forces landed.

The Riverway Amateur Radio Society will sponsor special event station GB70DDL from June 1 until June 28 from the Sea Cadet headquarters in Stafford, England.

On June 6, 1944, 160,000 Allied troops landed along a 50-mile stretch of heavily-fortified French coastline to fight Nazi Germany on the Normandy beaches. The attack was a major turning point in the war. More than 5000 ships and 13,000 aircraft supported the invasion, in which more than 9000 Allied soldiers were killed or wounded.
