Morse Code VS Text Messaging

I've seen this clip from Jay Leno's show on some Ham Radio sites:


Morse Code-Leno - More amazing video clips are a click away


It's a demonstration that Morse Code is faster than Text Messaging.

At least that's what it seems to be, but some have argued that if you had to send Morse Code over a cell phone, it would take longer to type all the dots and dashes on a cell phone keypad. Maybe, it sounds plausible. I don't do text messaging, so I can't say from experience.

But even if that is true, there may be a way around it. There is a portable accessory, that purports to make Morse Code and texting devices compatible:

Wireless SMS/IM/chat by Morse code
[...] The project's goal is to endow existing mobile devices and create new custom-designed devices with a Morse code text entry/output interface and allow them to tie into existing message-based communication networks such as SMS and IM as well as a new character-based chat medium in which each letter is transmitted as it is encoded. [...]

The author explains that Morse code would indeed be faster than conventional texting. Read the whole thing for the details, it sounds like it has interesting possibilities.

But that's not all, there is another device called "Clique" from Toshiba that also sounds interesting:

The wheel turns. What was old becomes new. Morse Code is back in favor.
Twittering text-aholics will soon have a new plaything: Toshiba has teamed up with American microprocessor giant Intel to produce Clique, a handheld, thumb-operated device that uses only three keys. Text addicts will need to learn Morse code.

Perhaps the most startling features of ‘Clique’ are its uni-directional text stream and its reliance on an old-fashioned technology: 160 year old Morse code. ‘Clique’ users can only text out. Responses are collected by the user’s designated electronic mail account. [...]

Much of the terminology used in computer networking and communications comes from radio terminology. It's interesting to see the many ways in which the two technologies are now converging.

Morse Code Study - Methods, Then and Now

I'm studying International Morse Code to use with Ham Radio, even though it isn't a requirement for a Ham license anymore. I would like to use it with QRP, which also interests me. I have a technician's license, which allows me to use some of the HF bands if I use CW (Continuous Wave, a.k.a. Morse Code). While researching studying methods, I came across this old film of a Morse Code Training Center, from 1941:



Gosh, it looks awful, and I though what I'm doing was hard. Looks like it was much harder in 1941! But I guess their methods worked too, since they graduated all those students.

Nowadays there are two primary methods, "Koch" and "Farnsworth". I've been studying with the Farnsworth technique, using the ARRL's double CD set, "Your Introduction to Morse Code".


I've been studying 15 minutes in the mornings and evenings for over a month now. It was difficult in the beginning (isn't it always), but I'm starting to catch on, and now it's getting easier, and as I learn more it becomes more fun. I'm up to lesson 16.

The ARRL (American Radio Relay League) website has a good Morse Code reference Page:

ARRLWeb: Learn Morse Code (CW)!

A Google search reveals a lot of info too, there are several free computer programs available for learning Morse Code. I had thought there would be a program that would give you the signal, allow you to type the corresponding letter, and give you instant verification if it is right or wrong, but I've yet to see a program that works that way. Does anyone know of such a program?

I'd love to hear from people who have learned Morse Code, and their preferences for what they feel are the best learning methods. Please feel free to share them in the comments section.

The American Radio Relay League, my missed opportunity, and my fun new hobby


As I've been reading up on Ham Radio (a.k.a. Amateur Radio), a hobby I've always wanted to pursue, I've found out a lot of interesting things. One of the more surprising things I discovered was, that the American Radio Relay League was founded in 1914 by Hiram Percy Maxim of Hartford, CT. Hiram was inspired to start the ARRL thus:
[...] In 1914, Hiram P. Maxim of Hartford, Connecticut, was a prominent businessman, engineer, and inventor (notably of the Maxim Silencer). He was also an active radio amateur, with one of the best-equipped stations in the Hartford area. One night in April he attempted to send a message to another ham in Springfield, Massachusetts. He had a one-kilowatt station (call 1WH), and Springfield was only 30 miles away, well within his normal range. He was unable to make contact, and remembering that he knew another ham in Windsor Locks, about halfway, he contacted the Windsor Locks ham, and asked him to relay the message, which was successfully done. This was not the first time a message had been relayed, but it set Maxim to thinking. At that time, a great deal, perhaps most of amateur radio activity consisted of sending and receiving messages, not only between amateurs, but involving the general public as well. But at that time the maximum reliable range of a station was a few hundred miles or less, and so Maxim realized that a formally organized relay system would be of tremendous use to amateurs.[7]

Maxim was a member of the Radio Club of Hartford, and he presented a plan for the organization of an "American Radio Relay League" (he had already decided on the name) to the club at its April 1914 meeting. The club agreed to sponsor the development of such an organization. [...]

The the ARRL outgrew the Hartford Radio Club and split off as a separate entity... there is quite a bit more history of it's evolution and struggles which I found interesting, including difficulties with the US government in WWI and WWII. So different from nowadays, where they seem to have reached harmonious accord.

The ARRL's current headquarters are in Newington CT, just south of Hartford. The ARRL today:
[...] The ARRL represents the interests of amateur radio operators before federal regulatory bodies, provides technical advice and assistance to amateur radio enthusiasts, and supports a number of educational programs throughout the country. The ARRL has approximately 152,000 members. In addition to members in the US, the organization claims over 7,000 members in other countries. The ARRL publishes many books and a monthly membership journal called QST.

The ARRL is the primary representative organization of amateur radio operators to the US government. It performs this function by lobbying the US Congress and the Federal Communications Commission. The ARRL is also the international secretariat of the International Amateur Radio Union, which performs a similar role internationally, advocating for amateur radio interests before the International Telecommunications Union and the World Administrative Radio Conferences. [...]

The irony is, I've long had an interest in Amateur Radio, and I grew up in Hartford county, near the ARRL headquaters, which is just a short drive from where I lived, and it's often open to visitors. I could have visited at any time, but I didn't even know about it. I love all that history, and it all started practically in my own back yard. But I missed it, I only find out about it decades later, when I'm living on the other side of the continent. Talk about missed opportunities! Darn.



W1AW, the Hiram Percy Maxim Memorial Station


There is plenty to explore though, at the ARRL website at: www.ARRL.org. It's a terrific resource that I keep going back to refer to again and again.

Presently, I'm studying to get my Technician's license. That test has 35 multiple choice questions. I believe you have to get 26 of the 35 correct in order to pass. Here are two on-line test sites I've been practicing with:

Ham Academy Practice Test
This site offers exam study notes, and a selection of questions. When you choose an answer, it will tell you right away whether it is right or wrong. It will keep score of your wrong answers, and tell you if you pass or fail at the end.

eHam.net Practice Exam
This site gives you 35 questions, and shows you the right and wrong answers and your score only after you have completed the 35 questions.

I've been practicing and passed the above two tests for the first time last night, but I'm going to practice more before taking the real exam. You can learn more about the exam process here:

What Amateur Radio licenses are available?

The Morse Code Requirement has been dropped from the tests. That makes it much easier than it used to be. But I think I would like to learn to use it anyway, eventually. There are computer programs that can help you learn it. You can often transmit much farther with Radio Morse code (CW) and with very little power, than you can with voice broadcasts. It could be fun to learn and use.

I think this going to be a great hobby, and I'm looking forward to it.
