Morse Code: A Staple in the Navy IW Toolkit
I went to the local HAM field days and a gentleman there was doing Morse code. It was interesting to watch. It really is a skill IMO. The beeps were coming in fast, he was writing and responding.
EU zone code 'Champ' - yes, they hold contests.
Video of 'DA', also known as Denice Stoops, the first female telegrapher who worked at KPH until the end of commercial Morse operations and closure of the station in 1998.
If you look at the rack mounted equipment just behind the operator, you will see a R-388/URR as the station backup Receiver (black faced radio).
Code operations isn't dead, it is just hiding out on the low end of 40 meters....
And, one can reach locations and nasty environments with morse (CW) that one cannot reach with voice.
Morse and PSK31 provide levels of security mainly because many are not setup for them..
Anyone can see them but many would not know what is illustrated below and if they did they are not setup to use it.
I love PSK

PSK31 - Wikipedia
Then there is the NUE-PSK modem for those that don't want to lug their laptops out in the field
Just the thing to use when out of town at the local glacier....
All runs from AA or 9V batteries. Great fun.
Morse is not dead, but it's not really relevant either. Back when I started in ham radio in the 1980s, the CW bands were jammed with dots and dashes. You could barely find a space to send CQ, and when you did, you would get numerous replies. There was always someone out there.
If you spin your dial across the CW bands today, you will find plenty of empty space and not many takers for a CQ. Hardly anyone sends code, and of those who do, many don't really "know code;" they are using software-driven keyers.
Knowing code is like knowing steam engine repair: It's interesting and cool, but it's a niche skill with very limited real world usefulness. I would suggest to a newbie that their effort would be better spent on the data modes.
That the Navy is teaching Morse is a nice anecdote, but it does not indicate a Renaissance for code. I'm going to be a cynic and speculate that the Navy does not care about Morse code one way or the other, but they got a pile of grant money and they have to spend it, and/or some well connected civilian contractor set himself up with a cream puff deal to develop the curriculum for the class.
Your cyncism may be correctly placed, but I'd hazard a guess that some of our putative enemies or their clients are not as likely to abandon Morse in favor of an expensive alternate. With the CTs taking the courses and not RM or SM, it points that way.
But yeah, newbs should be thinking digi, not morse.
Plenty of CW on the bands, but I've about given up because of the rudeness. If you don't send at a speed whoever can copy, or you ask someone to slow down, you get a ration of sh$t. The "gentlemans hobby" gets really nasty on CW and 160 meters.
A SONY General Coverage RX and a cheap ($20) Ramsey transmitter. Wire for the antenna.
Ham radio on the cheap...using CW
NG9D has a ton of fun you toob videos.
Or make your own from bits and pieces
I did always think that it would be great for a "group" to develop their own "Morse" type code. Something using dots and dashes, but completely different from Morse. Should they be able to keep the code and code books within their own group, it would probably be quite hard to crack.
Actually, NO... If the messages were in English, using a standard English Lettering System... it is entirely solvable using a Super Computer, by the Brute Force Method, by using common Letter distributions, and Vowel Distributions, in the standard English Language. Not near enough variables, to beat Brute Force, and once it is cracked the whole system fails... and then all the Operator Training is wasted... much better to use a One Time PAD System with variable Row/Column KeySets, like we using in MonkeyNet... Especialy when used in a Phrase PAD System, rather than a Alpha/Numeric PAD....
Good thing kids aren't into radio, and learning code.
If it were me ( as a kid) I'd build a key pad in my shoe and do code with my toes, then build receivers that look like hearing aids.
The electronics for sending and receiving code are especially simple.
Most young people are too lazy to earn electronics.
It would take texting to a whole nother level.
But CW is faster than texting- at least on the Jay Leno show,...
Guiness world record texting dudes and a couple of hot shot CW operators.
Blast from the past! I learned code at Corry Station in Pensacola, FL back in 1990. Be damned if I rem even a few of the standard terms. I'm pretty much reduced to good ole SOS these days. That one's pretty hard to forget. I do still have my hand written notes in a box after my last move. Last time I looked through them I realized how much I've forgotten of the things I once knew.
Trying to learn it now, it might even help keep the old brain from rotting. Also useful for QRP as that's all I have at the moment.
Look at the benefits: judging from your thumbnail, I assume you're a pilot, so you'll be able to ident VOR's without looking at the sectionals!
Well, any "Caesar cipher" can be broken quickly, as has been pointed out. Sir Arthur Conan Doyle did a Sherlock Holmes story called "The Mystery Of The Dancing Men" that illustrates the process.
However, any code provides some security, especially if employed for tactical movement orders when there isn't time to decode it.
You could learn and use American Morse to give you that "Magic Minute" edge, where the orders are carried out too quickly for translation are countermeasures to be effective.
The little bit that I do know came from VOR's. When I first started flying in '59 that was the only way to be sure. Don't fly anymore but I did like that Apache 235. Listened to some code today (I finally got an antenna up and my KX3 hooked up to it, even with the decoder on, it was gibberish. Did hear a guy K3FF in northern California but I was only putting out 5 watts outside and he couldn't hear me. Oh well, there will be another day
This is why-
pretty funny but I have heard much the same upon occasion. Happily, on the FT-817, the mike UP/DOWN keys can be used as...
I just came across this online Morse code converter.
It's handy for decoding posts that have code in them.

When I read DKR's post I got to thinking.....
(I know usually that is the first mistake :D)
Had this discussion with my son last night.
Separate names with a comma.
