The ARRL kicked off 2011 with a news item that hopefully is not a harbinger of more retro-tech lameness to come during the new year. (Hint: It is.) "Ring in the New Year with Morse Code Ringtones" started off well enough; make your cellphone ring with CQ CQ CQ or some such. I did this almost two years ago and it's great fun; I even made ringtones with my wife's name, the callsigns of hams in the Bay-Net group, etc. I got lots of good comments on my ringtones from folks at the 2010 Dayton Hamvention; a few even requested that I email them copies of my MP3 files for their phones.
The ARRL article fails on two fronts; first off it talks about creating Morse Code ringtones like it's a completely new thing (clearly it's not), and secondly it goes into detail about the horribly convoluted process Tom AD1B used to create his tones. Tom actually used his Ten-Tec rig and a keyer paddle to generate the Morse Code, recorded the audio (article is unspecific on how he did this; my money is on "8-Track Tape Deck"), massaged the audio files in Audacity, and then generated MP3 files. Talk about using a bazooka to kill a mosquito.
Clever. And completely unnecessary. I generated my MP3 files by going to LWCO.net, a website created by Fabian Kurz, DJ1YFK. Fabian's website (the URL is an acronym for "Learn CW Online") offers a number of useful tools, many of which are based on Fabian's excellent open source "ebook2cw" library. One of the tools on LCWO is "Convert text to CW". You type in text. It generates an MP3 file for download. You put the file on your phone. Done. I can generate a library of unique ringtones for twenty people in the time it takes Tom to record and process one.
And even my method is now somewhat obsolete with the advent of apps for smartphones that convert text to Morse Code on the fly. MorseRing for Android is available in the Android Market for 99 cents. It converts Caller ID strings to Morse Code. The beauty of MorseRing is that I now know who's calling me even if my phone is 25 feet away. I'm sure there is similar apps for the iPhone, possibly one for Palm, likely not for Blackberry.

Way to Encourage New Ops, Dude
I'm on 80m right now listening to a Cuban station (CO8LY) on CW. The guy is doing well, about 15 wpm with a 9 wpm Farnsworth rate; just my speed. He's got a good fist and is managing the pileup well.
Three times in the past half hour I've heard guys come back to him at well over 25 wpm. He's patiently trying to confirm their calls, sending bits with a question mark at the end. It's clear that his max rx speed is around 9 wpm. And yet; these clowns won't slow down for the guy! It's like they're insisting that he match their speed. Unbelievable.
Why do CW ops do this? Slow down. It's not a race, not a competition. He who dies with the fastest key doesn't win. Give the kid a chance to learn and maybe in a few years you can work him at 30 wpm if that's what gets you off.

..-. .. .-. ... - -.-. --- -. - .- -.-. - <= (First Contact)
This week marked a big milestone for me; I successfully completed my first radio contact using CW aka Morse Code. It was a tough contact; conditions were bad but the guy I worked was polite and patient with me so we managed to pull it off.
I had always believed that I simply did not have an "ear" for code; it sounded like noise to me and I was never able to get past a basic understanding of the mechanics. After the amateur radio code requirement was lifted I was thankful and quickly upgraded to the highest level license. Still, in the back of my mind I felt I should make a real effort to learn code; if for no other reason than to overcome a personal limitation. (If you think I have a strong aversion to being told what to do; I have an even stronger aversion to being told what I can't do -- even if I'm the one doing the telling.) So my 2009 resolution was to learn enough code to complete a radio contact. It took me nine months, but I made it. I don't know that I will ever be a "real" CW operator, but right now I'm having fun and feeling good about my accomplishment.
I would like to thank the following people who helped make this happen for me:
- Gerald Wheeler (W6TJP) - Author of the Code Quick learning method. A great basic foundations course.
- Fabian Kurz (DJ1YFK) - Developer of the LCWO.net website. An awesome online Koch-method trainer. Did I mention it's free?
- Leon "Skip" Stem (WB4DAD) - CW operator, FISTS member, and the first entry in my CW contact logbook. Thanks for being patient with me.
