LCWO on iPad & iPhone

Great news for owners of Apple portable devices who want to access Fabian Kurz DJ1YFK’s brilliant lcwo.net site on the move. LCWO stands for “Learning CW Online”. If you don’t know the site and you want to learn morse code or improve your code skills, this is one of the best destinations available – and it’s totally free.

Since May Fabian has been working on alternative ways to deliver the material, using HTML5 as an alternative to Flash.

As of Tuesday this week, Fabian has enabled the HTML5 player option to work with Apple Safari so it can handle mp3 files. And now at last iPhone and iPad owners can use the site as it was intended. Now I have no excuse for not getting my CW into shape.

Another cause for celebration is that today the lcwo.net site welcomed its 20,000th visitor. As Fabian says on the site “The reports of CW’s death are greatly exaggerated.”

Subliminal morse

Tim G4VXE posted an interesting ‘random’ thought about one suggestion he’d heard recently on air to raise your CW speed:

“one of the ways to improve your speed and competency is to listen to as much morse as you can – for example, have the rig running whilst your watching TV or reading. It’s almost as if the subconscious brain starts to process it and it becomes a ‘background process’.

This will help you if you want to be able to send/receive morse at the same time as doing something else.”

It can’t hurt – apart from driving all those around you crazy – and convincing them of all the doubts they already had about you! But maybe that’s what the headphones are for.

Overland Telegraph – 140 years ago, yesterday!

An ABC News story today tells of the celebrations in Darwin this week marking the start of the Overland Telegraph on 20th June 1870 when the South Australian parliament voted to dedicate about half its annual budget to building the telegraph line!

CW resources

Via a link to a Facebook page I found two morse related application (for Windows) here. This page is interesting not just for the RSS Morse and Morse Keyer programs, but also some handy morse related links.

I discovered a free pdf book ‘Zen and the Art of Radiotelegraphy’ by Carlo Consoli, IK0YGJ. Interestingly Carlo wrote the book in Italian, translated it into English himself and then got Ulrich Steinberg, N2DE to revise the book. Net result: Very readable! When you think about it the first thoughts behind the first morse signals to hit the ether would have been in Italian! Carlo also salutes craftsmen such as Piero Begali I2RTF, Salvatore Canzoneri IK1OJM and Alberto Frattini I1QOD.

There are also links to versions of The Art and Skill of Radiotelegraphy by William G. Pierpont N0HFF (3rd edition – 20 April 2002) and Using an Iambic Paddle by Chuck Adams, K7QO.

Also via a post to the CW email group a link to K6DBG’s page on ‘Some things I’ve discovered about learning and operating CW and a link to a a cross-platform Morse program http://c2.com/morse/.

This site is the distributon site for current and historical versions of A Fully Automatic Morse Code Teaching Machine first described in a May 1977 QST article of the same name by Ward Cunningham.

Ward Cunningham of course is the ham who also developed one of the earliest wikis on the web at http://c2.com/cgi/wiki.

USB morse key

Via Julian G3ILO news of an Arduino based project to build an inteface to enable direct input to a computer with a morse key. Lots of information can be found here.

It looks like a neat little project. I don’t get the feeling it’s going to be offered as a kit or anything. Most of what you’d need to know to make one is on the site including a schematic and the code that decodes the morse code!

This is similar  – in concept at least – to those iPhone morse apps where you can tape the screen in the same way you would a straight key, and the app gives you feedback on your morse – at the most basic level by translating it back to what you hopefully intended to say.

What would be even more exciting would be an interface that could also handle paddle input to PCs … a bit like the $1.99 iPhone app iDitDahText by Marc Vaillant. You can only load this one on to jailbroken iPhones. It’s available via the Cydia Store. It enables you to enter text in all iPhone apps using the equivalent of an iambic keypad on the screen up to 50 wpm. Great party trick!

Or better still isn’t there a way to connect the output of the iPhone or even the iPad – electrical not audio – to control a keyer and a transmitter. Throw in PTT control while you’re at it!

The creator of the Continental code

Friedrich Clemens Gerke
Friedrich Clemens Gerke

I stumbled on to a page on Wikipedia about Friedrich Clemens Gerke, (22 Jan 1801 – 21 May 1888) the man responsible for simplifying Vail and Morse’s original telegraphic code.

As the wikipedia article explains, “The original Morse code consisted of four different hold durations (the amount of time the key was held down), and some letters contained inconsistent internal durations of silence. In Gerke’s system there are only “dits” and “dahs”, the latter being three times as long as the former, and the internal silence intervals are always a single dit-time each.”

This chart reveals the logic behind his reform of the code.

After some minor changes it was standardised at the International Telegraphy congress in Paris in 1865.

Portuguese in morse

This page has a listing of how different alphabets and accented characters are sent with morse including Russian, Greek, Hebrew, Arabic, Japanese and Korean. I feel an overwhelming urge to change it from its dots and dashes layout to a didah format to reinforce the sound and not the visual structure of the characters. As comprehensive as these charts are, I’m still a little in the dark about some accents used in Portuguese. It could be that they’re simply not used in morse. Maybe listening to QSOs is the only way to confirm this.

Even the listing on the Portuguese Wikipedia page is missing the ã character. And this Brazilian page makes no mention of accented characters, even though it does explain that the codes for each character reflect their frequency in English.

CW Operator’s QRP Club Inc

I rejoined the CW Operator’s QRP Club Inc. after a long absence. I was surprised to discover I’m entitled to my original membership no #56. It’s probably been almost two decades.
