You're doing it wrong

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.

An example of why amateur radio is failing to attract young people

I follow various hams on Twitter and in blogs. Some because they're friends, some because they're part of my local radio community, and some just because I like what they have to say. There's another smaller group I follow, which is people I tend to not agree with. In the same way that conservatives will listen to NPR and watch CNN as a way to better understand and counter the liberal/socialist viewpoint, reading these people's tweets and blogs helps me understand why amateur radio continues to slide into obscurity.

Mike WA4D's "MEWCOMM" blog and Twitter commentary is one which I typically don't agree with. His position on matters relating to amateur radio are highly representative of a mindset which pervades the hobby, and which I believe is ultimately counter-productive to the hobby's evolution. I will use Mike's writings as proxies for opinions held by others, so apologies to Mike in advance; this is not intended to be a personal attack at you. To be fair; I like and agree strongly with Mike's perspectives on politics and foreign policy, but his judgmental attitude towards no-code hams (i.e. those who have not learned Morse Code or "CW" in the parlance) happens to be a perfect example of why amateur radio is failing to attract young people into the hobby. A sampling of Mike's comments include:
  • People who don't know how CW "are not real hams".
  • Removal of the CW testing requirement was equivalent to "affirmative action" or a "back door".
  • CW defines the "soul of the hobby" and "defines what a real ham is in the 21st century".
In 2006 the FCC was in the process of implementing WRC-03 recommendations which would later eliminate CW testing as a requirement for amateur radio licensing. I filed comments with the FCC during the comment period in support of this decision, in which I asked "Is the true measure of technical prowess the ability to understand what amounts to a language?" Indeed; my experience is that hams who know code are no better or worse operators or technologists than hams who don't know code. Some of the smartest hams I know -- hams who have contributed real value in the application of computing technology to radio -- are Extra-class hams who never learned Morse Code. My opinion? These people, and the technology they're developing, will truly define amateur radio in the 21st century.

Mike recently wrote that no-code hams "know not of the 'thrill of recognition'", which I infer to mean that they're not real hams because they're never experienced the "satori" moment of completing their first Morse Code contact. Having experienced the "thrill of recognition" for CW and other modes I can say that while the satori moment for CW is indeed exciting, it's no stronger or more "real" than the satori moment I had when I made a 10,000+ mile contact using JT65A on HF at 50 watts of power into a hand-made antenna cobbled from $2.00 worth of spare parts and wire. I remember both experiences equally well, and yet the JT65A contact is more memorable (and a source of greater pride for me) because I did it using a new (at the time) mode on jury-rigged hardware. But following Mike's logic I guess this wasn't a real accomplishment because it involved use of a computer, and at the time I didn't know how to send & receive CW..?

Amateur radio is a "big tent" hobby which offers something for everyone. If the hobby were healthy, growing, and not in danger of obsolescence I would say "Live and let live" and be done with it. But opinions such as "people who don't know or use CW are not real hams" are too prevalent among a majority of hams, with the end result being that bright young people who might want to explore amateur radio's application to computers and digital communication are scared away by older hams who insist on defining "real radio" in terms that they can understand.

The danger is that, as older hams pass on and are not replaced by younger hams, we will reach a point where the government decides that amateur radio spectrum can be put to better use. ARRL or not, the ham population will be too small to defend our allocation, and combined with decreasing relevance and value to emergency communications we will eventually lose our spectrum. Proficiency in CW and adherence to traditions will not solve this problem and help us keep our spectrum. The only solution is to open our minds, embrace change, and get over this self-defeating need to hold up 100+ year old technology as the gold standard against which new technology must compare.

The crux of the problem is that the prevailing majority has defined amateur radio and its reverence of traditions as an immutable core. This is horribly wrong and ultimately self-defeating. We should instead be seeking ways that encourage the applying of amateur radio to new technologies, and in doing so continuously finding new relevance and recruiting new hams. "Real hams" are those that are creating innovative technology which applies amateur radio to technology, such as Chris K6DBG's hack that converts a Wi-Fi router into an APRS receiver. Speaking the "language" of Morse Code isn't proof of technical ingenuity, doesn't prove that a ham is innovative or intelligent, and arrogantly judging hams based on their ability (or not) to use CW drives away new recruits and will NOT save our hobby.

..-. .. .-. ... - -.-. --- -. - .- -.-. - <= (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.
