Even though ARRL no longer considers morse code mandatory, do you folks still maintain proficiency?
Seems to me that a basic familiarity with code is a must have for survivalists.

I just got my Tech... I haven't learned code yet. I plan on it once I upgrade to General, I figure I'll need it once I really start exploring HF.

LR,
A coupla freebies:
Learn to associate the sound with the letters rather than the images. Flash cards are a quick way to do it, but you have to say the sounds of the code out loud.
Also, if you have someone to correspond with in code it helps add some fun to the exercise.

Example:
Dahdahdit dididah dahdit dahdidit dahdahdah didahdah dahdit dahdahdit didit didididah dit dididit dah didididit dit dahdididit dit dididit dah didah dahdidit didididah didit dahdidahdit dit

I'm going to make myself do it eventually. I suspect it's going to be a lot like memorizing all the damn drugs I had to memorize while going thru paramedic school though. I hate memorization so it's going to be one of those things I have to make myself do.

I'm a no code. I have a Rockmite CW QRP radio kit though, so maybe I'll have to learn it eventually.

But it's a relic from a bygone era.

Hi all,

I am new here, but I have a Extra ticket. If you want to learn morse code, I would recommend this little program. It's free and very handy.

DeltaEchoVictor,
The way I worked it was to break it down into 4 chunks by audio pattern.
First group are E,I,S,U,H,V, and F because they all start with a "didit" pattern.
Next, the "didah" group, then incorporate the two, and so on.
It's more important to work from pattern to letter rather than letter to pattern. Remember that there's no pattern between the appearance of a written letter and it's sound either and you managed to pull that one off.

Thx for that link slugg. I DL'd it and I have been practicing all day. I want to learn it but not sure if I'm gonna be very proficient.

Try these 2 practice programs as well:

http://www.rufzxp.net/" onclick="window.open(this.href);return false;
This just beeps out callsigns to you. Get one right and it moves up 1 word per minute in speed; miss one and it drops 1 wpm. Basically it constantly nudges you to get *just* a little faster with your copy while adjusting to what you can handle. Astonishingly effective and even more addictive.

http://www.dxatlas.com/MorseRunner/" onclick="window.open(this.href);return false;
A CW contest simulator. If you're a ham at some point you'll be bitten by the contesting bug. It will take you about 2 contests to figure out that the REAL points are on the CW sub-bands. This is especially true if you have a local noise problem or if the sun doesn't freckle up; CW gets through when voice just can't do it. This program simulates running a pile-up in a cw contest. Again, ADDICTIVE.

Both of these programs work really well for me by turning what used to feel like homework into what feels more like a weird audio version of a video game.

i occasionally have fun with morse code - i first learned it back in the early 60s

After you learn morse well for the first time it's kind of like learning to swim or ride a bicycle - even after laying off for years it'll come back to you really quickly

I'd guess with a month of copying the code off of the air and practice I could get back to 13 wpm after about a month

I got up to 15 wpm back in the day when I got my General, but only have used it to teach others Morse code in license classes, never tried it on the air. Not that the code isn't required for licenses, I haven't had any practice since.

Yeah, I used to be fast enough with morse to translate and reply by sound on the fly... but I'm a bit rusty with it now... I have to actually think about it now.

I disagree. If you listen to the Tucson police scanner, they use morse code all the time. I don't understand it so I have no idea what they are transmitting, but I bet that is the point.

How hard would it be to connect an analog reciever that works in morse to a digital reader that translates it into text on-the-fly?

I (and another guy) built a device in college that connected to a shortwave radio, took the morse code signal, cleaned it up and turned it into a series of digital pulses, fed it into my prof's Apple IIc computer (it was 1982), translated it into English, and displayed it on the screen. That project was a bitch. The computer wouldn't run fast enough to keep up using the translation program I wrote in Basic, so I had to teach myself assembly language to make it run fast enough. Part of the project was based on a circuit in a book, which had the pins labeled incorrectly on a IC chip, which took us days to figure out. We finally got it to work for the first time three hours before it was due.

Anyway, morse code is still a very valid mode of communication. When there is so much noise that voice is incomprehensible, morse code is still very clear. I know a guy who is really fast. At his best, he could go 50 wpm. He works CW while driving. He has a key strapped to his leg, and since he hears code like you and I hear words, he can easily work CW.

Yes, that's been available for a while. The easiest method, since you have a computer, is to just put a cable from the headphone jack into your soundcard. Then run a free program like CW-Get from http://www.dxsoft.com/micwget.htm to decode the CW. There are a LOT of ham programs and modes that use the soundcard as a modem.

There are also purpose-built devices like some products from MFJ Enterprises:
http://mfjenterprises.com/Product.php?p ... d=MFJ-462B
http://mfjenterprises.com/Product.php?productid=MFJ-461

Decoders like these work best with machine generated CW with perfect dit-to-dah ratios. If there's too much static or if a human has a sloppy fist they can't get the job done as well. In those situations the best decoder is still the one between your ears.

I still haven't found a practice generator I like. The AA9PW practice page is a great idea, but it's just a little too quick between the letters for me to decipher. If you slow it down, it adds space between the words.
I can code the alphabet at 7wpm, but some of the letters are automatic (like C) and some of them make me stop and think (like W).. Still a work in progress.

I found a really good freeware trainer here. I've downloaded it on both my computers and it runs bug-free.
It allows you to learn one new character at a time in a way that programs your brain to automatically think the letter when you hear the sound. It also simulates background noise, station fade, faint background stations, you name it.
