Since marine and aircraft no longer use CW, there's no need for
CW beacons. I think you'll find that they're all using digital
communications now. I think it was France who announced back
in 1998 that the end of that year (or the following February)
signaled the end of their CW in their maritime service. I
believe the announcement said that they were the last country to
do so.
I think Britain still has maritime non-directional beacons (NDBs)
that identify themselves in Morse,
and I'd be surprised if our coast guard were not equipped to receive
it.
I can understand the reduction of Morse code use, and I don't necessarily believe it should be compulsory for amateurs -
but I think it's important to recognise it's potential as a fall-back system.
Even if you can't modulate a carrier for some reason - if you
can oscillate, you can communicate.

Maybe 100 years from now, somebody will make a war movie where a platoon
is cut off from headquarters and their radio is broken. Pretty soon some old Master Sargent remembers his great grandpappy taught him enough Morse Code to be dangerous. So he rigs a switch to the finals and uses a couple of empty cartridges for the make and break. He's all set up and sending code, but the people at headquarters don't have the slightest clue what that clickety clack interfering noise is in their speaker...

If you have a good STRONG light source, one that reaches the receiving location you can talk over a light source with voice. That was demonstrated to my science class in the 30's. Of course, that can not
be done if the light is very far away, or weak.
Which brings me to a natural question. Since doing away with morse
code as a communiction method, what happened to communication between
war ships by flashing light? I would imagine that semaphore by flag
is still in use, but in Radioman school we learned that communication
by light was one of the most secure means of communication since it
was limited by visible line of sight only, (next to semaphore), which
had a shorter range of visibility.
job with the CG was as a radio station manager on our
Point Loma CG radio station here in San Diego.
Well, he certainly ought to know! =o) I can understand
the logic behind switching to a (computer) digital system for
day-to-day use, but I hope they still monitor for Morse distress
signals if nothing else.
As you know, the requirements are being phased out in
the FCC testing.
Things certainly point that way (5 WPM and all that).
Have the FCC said that they will eventually eliminate the
requirement?

They still can earn credit towards a Merit Badge for using a
Heliostat, neede code for that. . And as a side note while not
really "Code" related they still teach signal Flags. It is all
optional of course. And I read once in a while in Club Newsletters of needing Hams to go out the assist in communicating between Hilltops
while the scouts are trying to pass off a Merit Badge element.
The modern equilivent of that uses Lasers. And it increased the range quite a bit
But becasue of safety factors the power should be limited.

NOW...... That reminded me, years ago (in the 1980's), there was a report on TV of a laser system transmitting video from the USA to
Canada at Nigara falls. One hotel room to another. It was being used
to transmit pornographic movies over the border without having to go through customs (where porn was confisticated).
Regarding the light source, life jackets (for use at sea)
had a mirror and target sight assembly that could be used for
signaling to a search aircraft and could also be used for sending
info using morse code (If I remember, the code was printed on the
back of the mirror).
Thanks for that info, Tom. And since they are communicating between hilltops I wonder if they're making use of the 460Mhz range FRS handi talkies? I've got a pair of them but can't get the XYL to talk to me. Rats!!

I don't know that they do, but it's easy enough for ships at sea to send morse over broken microphones on maritime frequencies as well as those marine channels the CG monitors, if the need should arise..

Only if you have one of those with the momentary button. I could never get those slide switches to work 100% the way it should to generate intelligable code.

Well they Don't. The old CW system is totaly shut down and the frequencies are no longer monitored.
These days with computer technology, anyone can send and
receive morse from the computer, yet, don't know if it is true as the
ITU won't tell me, it has to be sent manualy.
I mean if the British Army, Navy and most of the RAF no longer use it,
why should prospective amateurs have to learn it for either a class A, 12wpm or M5, 5wpm ?.
Personal view only, but welcome comments
The signaling mirror was simple but effective. There was a hole in
the middle of the mirror (chrome plated metal) and a hand held target
with cross hairs and a hole in the middle. You held this target at
arms length and then looked at the aircraft (or whoever you were signalling to) through both the hole in the mirror and the hole in
the target. You then moved the angle of the mirror so that the sun
either did or did not shine on the target. Simple but effective.
Thanks for your very interesting reply.

I thin kthat is the one I am Thinking about. And Ironicly as I hear it the Russian Sat's that cound pick up the same signals worked Better then the
put up by the United States.
Kinda tough to make a slide switch, water proof, so the pushbutton continues to be made in top quality flashlights.
But what good does it do if NO one can Copy it at the Listening Station???
Good point. What I'd like to think is that whoever is listening would be aware enough to alert someone who just might have an idea of what that funny sounding stuff is.
I belong to No Code International, a group led by W5YI, dedicated to lowering if not eliminating the code requirement in Amateur Radio. There was an earlier group in New Zealand that brought it to the IARU table a couple of years before NCI got on the band wagon.
Why shopld the Ham Community be Dictated to by the Military???
Did I say they were ?, all I said was that most of the UK military no longer use morse.
I have had fewer than half dozen phone QSOs in the past 15 years or
so. I hated having to learn the code (13 wpm) and wish there was NO
code, hi. But after learning it I worked CW all the time. Mostly cuz
I didn't have the money or know-how to build a modulated rig, hi. My
rig for the past 18 or so years has been a CW only Heath HX-1681 and matching HR-1860 rcvr. I have a bunch of older stuff too, but just
can't see that I'd get much fun from operating a store bought rig,
hi. Might break down and get a rig some day though, if I can find
one simple enough.
How about taking my message with a grain of salt? Keyboard and
computer use is more like TTY than CW. In the 40's we had a blind
ham, W5LDM, could tell some light from dark. I put a 100ma lamp in
series with his 807 plate voltage instead of a meter so he could tune
up. I know; some people have keyers that have a CQ and their calls
in it, etc, so that they can just sit back and let the keyer do all
the work. If you like that, fine. I'd rather use a real key as long
as I'm able to do so.
It seems to me that sending and receiving code by computer is no more working CW than Lip Syncing Caruso is singing opera.

Which brings up an Interesting point in Flashlight Design. In hte
Ond days they had a three position switch typicaly. Off/Pushbutton
ON/ON Now days it is either a OFF/ON slide switch or Pushbutton.
...it's easy enough for ships at sea to send morse over broken

That's a good point.
It's one of those things that's decided by the international
meetings held about every two years. I'm thinking IARU, but
may be mistaken on that.
I hadn't realised that it had been decided on an international
level, that's interesting.
It seems to me that sending and receiving code by

This is true to a certain extent, but chew on this.
What if the person has a hearing problem ?.
The way things stand at present, he/she would never get a class A or
even an M5 licence.
What about repetitive strain injury using a key ?.
Yes I know that you can suffer RSI with a keyboard, but not as likely
as using a key.
As for your comment on not being "Real Sending", of course it is, and
is likely to be better than 90% of the CW I have heard sent manualy.
It makes no
difference how it is sent and received, don't forget repeaters send
the callsign in auto CW, or is there a little person sitting there 24
hrs a day to send it every 10 mins or so ?.
What next, politicians/organisations telling us what stamps we can
collect ?
I'm not saying scrap CW in toto, just make it optional, and allow the
use of computers to tx/rx
Loved CW. Saddly I didn't inherit any of those traits. I flunked the
Code test for the First time in 1949 and numerious times since. It
just dosen't click in my Brain. .
