This fascinating 1943 U.S. Navy training film shows "How to Signal" using flag hoists, semaphore, and blinker to present morse code messages. The film was produced by F.H. Hargove of the Prior Motion Picture Company in New York and supposedly narrated by "Radcliffe Hall" (like a pseudonym for a radio announcer). A review in "Motor Boating" magazine noted that "the film shows pictorially how to learn the codes in the International Flag, Semaphore and Blinker systems of Communication. Expert signal men in the U.S. service serve as instructors and demonstrate the correct methods of using these three methods. It is designed so that the film may be repeated again and again until the student becomes familiar with the signal flags and positions of the semaphore, and the light flashes of the blinker…"
Flag semaphore is the telegraphy system conveying information at a distance by means of visual signals with hand-held flags, rods, disks, paddles, or occasionally bare or gloved hands. Information is encoded by the position of the flags; it is read when the flag is in a fixed position. Semaphores were adopted and widely used (with hand-held flags replacing the mechanical arms of shutter semaphores) in the maritime world in the 19th century.[citation needed] It is still used during underway replenishment at sea and is acceptable for emergency communication in daylight or, using lighted wands instead of flags, at night.
The use of lights for spelling out messages in Morse code dates back to 1867. With the advent of electric lights in the 1890s, the "blinker light" became an effective tool for signaling. Most widely used by naval ships, blinker lights were essential for merchant ships sailing in wartime convoys and observing radio silence. Blinker has remained a useful backup for merchant vessels, and until the late 1980s deck officers were trained in its use. Usually however, blinker work was done by the Radio Officer.
Beginning in the 1930s, both civilian and military pilots were required to be able to use Morse code, both for use with early communications systems and for identification of navigational beacons which transmitted continuous two- or three-letter identifiers in Morse code. Aeronautical charts show the identifier of each navigational aid next to its location on the map.
Radio telegraphy using Morse code was vital during World War II, especially in carrying messages between the warships and the naval bases of the belligerents. Long-range ship-to-ship communication was by radio telegraphy, using encrypted messages, because the voice radio systems on ships then were quite limited in both their range and their security. Radiotelegraphy was also extensively used by warplanes, especially by long-range patrol planes that were sent out by those navies to scout for enemy warships, cargo ships, and troop ships.
Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns) as standardized sequences of short and long signals called "dots" and "dashes", or "dits" and "dahs", as in amateur radio practice. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.
Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission. To increase the speed of the communication, the code was designed so that the length of each character in Morse varies approximately inversely to its frequency of occurrence in English. Thus the most common letter in English, the letter "E", has the shortest code, a single dot.

I retired as a Master Chief Signalman in 1996 after doing 31 years; learned the rating OJT at a Harbor Entrance Control Post in Vietnam where I was field promoted to SM3. I taught "A" school in San Diego 1975-1978, made Chief there. I served in USS Guam (LPH-9), plank owner USS Ainsworth (DE-1090), USS San Bernardino (LST-1189), USS Gridley (CG-21), USS Vincennes (CG-49) and plank owner USS Essex (LHD-2). I was also a Recruit Company Commander at RTC San Diego in the mid '80s. It bothers me that the Quartermasters who were supposed to take on the duties and responsibilities of the Signalman rating have let it die. The USS Zumwalt class of DDGs were built without a mast, no yardarms, no flagbags, no sem stands, no 12" signal lights; what are they going to do when EMCON (electronics silence) is set?
Master Chief Azevedo, It is great to hear from an old salt like you. My name is Lance Schoenbaum, Retired as an SMC(SW/AW) in 2004, the day before the rate went away. I knew you from ATGPAC and the ESSEX. I served on Tarawa with Gene Dempsey and at ATGPAC as a VisComm instructor in 97-99. I agree completely as the rate was allowed to die, and now I understand they don't even have the ability to talk with anybody without radio or electronic means. May not have meant much during 20 years of the "War on Terror" but with the Russians around, you better know how to operate in EMCON. My career path USS Lang (FF-1060), USS Ranger(CV-61), USS Thach(FFG-43), USS New Jersey(BB-62) NavCruitDist Chicago, USS Constellation(CV-64), USS Tarawa(LHA-1), ATGPAC, USNS Rappahannock(T-AO-204), NWS Fallbrook and USS Rushmore(LSD-47). I always remember Gene Dempsey telling a story about you on the Gridley? telling the XO he had the ship up his backside. How your evaluations suffered from that. In 2002, when I was an SMC on Rushmore, I defied the XO in Pearl Harbor over some ridiculous stuff and I went from number 3 CPO to 23rd ranked! So much for SMCS! Hope you are well, Lance
These Signalmen are from the US Coast Guard, not the US Navy, but even so what a great upload!! Gotta say right now that I had (even after all these years!) no trouble in reading the semaphore & flashing light! But I must admit that when reading the flaghoists, I might've been a bit rusty on the Numeral flags & pennants. The alphabetic flags are easy, it's just the others that I need to brush-up on!!
It's weird hearing "George" instead of "Gulf" or "Zed" instead of "Zulu"
My father was a signalman in the Us Navy 1942-1946 out of Pearl Harbor in the Pacific theatre! Great Film.
My great great great grandfather was too!!
When I went to signalman "A" school in 1978 we had the new phonetic alphabet. The first day they gave you a deck of flash cards with pictures of all 72 flags, the semaphore positions and the morse code equivalent. Had to memorize them for a test on the next day. One of the hardest exercises I've ever put my mind to. And the school was ten weeks.
Thanks for your service to our great nation.
DAMN.........
Our Chief made the whole class wear mittens after our first test. He didn't want us "talking" with our fingers. Dis my "A" School in 1976, San Diego.
I was in early 1979, and the class was only 8 weeks. I thought the Morse code was very easy, as was F/H, Semaphore was easy at first, but became hard as I'm just a little dyslexic... Were you in Florida?? BTW, do you know where to get any of the Morse Code manuals??? Take care! BZ
83 - 87 Navy A school Orlando, you had to have your shit together.
I can see myself watching this many times, it's truly fascinating. Thanks for uploading
This is exactly how to reach our brains through our eyes reaaaally fast! Or flashcards. School crosswalk guides carry small stop signs. Ping ping sized signals would give deaf and hearing challenged individuals a way to collect a higher count of points in less time.
the USPS sat atop my work line in California as I entered the workforces. Yes they did.
Thank you for sharing! My husband was a Signalman on the USS Midway '78-'80.
It's a shame that the SMs are no more.
God bless your husband for his service to our great nation
A wonderful rate! In the old days, they were signal quartermasters. I was a radioman.
I guess I'm kinda off topic but do anybody know a good website to watch newly released movies online?
@Lyle Aries try Flixzone. Just google for it :)
@Boston Marley Thanks, signed up and it seems to work =) I appreciate it !!
0:50 Flag Hoists

PeriscopeFilm: Thanks for this post. I've been up and down YT for a few days trying to find anything on Blinker Light Training. Finally!
Excellent -- yes this is quite a rare one!
Wow. So much data in such a small space of time.
Brevity. Always expressed in the Navy and the military.
My uncle was a signal man on U S S Oyster Bay and USS Wasatch in WW2. Pacific. My dad, who was also in the Pacific on a PT boat , called him a "scivy waver" ! Any info. on those two ships would be appreciated! Hats off to the Greatest Generation!
My grandfather was a "Wig Wag" on the USS Wyoming circa 1912?
SM3 (passed test for SM2 but got out) twenty three years ago brought me here. U.S.S. KITTY HAWK (CV-63)
Signalman here. Graduation was in 1995. Miss it and I am sad they folded the signalman rate into quartermaster
"There this should be slow enough." IMI All After "WHAT? The first word?" Ah yes the glory days..
Are you sure this is a Navy film? That's Coast Guard music. Really enjoyed looking into that old signaling world. I don't know if flags are still used in the Navy/Coast Guard, but I know the Air Force discontinued training members in Morse code several years ago and the other services have probably done the same.
One of the msgs was: join the us coast guard.
@@operatorjeffdeathstar7759 The Navy, Coast Guard, and Merchant Marine all had similar uniforms in WW2, so...no.
@@operatorjeffdeathstar7759 Then why is the Navy playing the Coast Guard song and saying "join the US Coast Guard?"
Wes - For info on the USS Oyster Bay snd USS Wasatch, check the Dictionary of American Naval Fighting Ships, or go on line and check the ship names in Good Search. The Naval History section should have a fair bit if info on both.
I feel like these changed over time in changing times.
EXCELENTE PELICULA DE ADIESTRAMIENTO¡¡GRACIAS¡¡
!De nada!
So interesting!
When I was on the ship, they teased us and called us cheerleaders, for using the semaphore flags. Lol
Edward John Rogan 1920 to 1979....US Navy signalman 1941 to 1945...gave the signal to proceed ashore to Omaha Beach on 6 June 1944 .
Memories, of being in Signalman A School in 2001, Great Lakes IL. The rate got absorbed into the Quartermaster rate in late 2003. I switched to be a Culinary Specialist (CS) in 2004. #HOORAHH!!!!
I respect all ratings. But....by the time I had completed my 90 days of "Mess-Cranking" I'd had enough of the mess decks. TY very much !
🤣🤣🤣
I love how in semaphore when they make an error they just flag “E-E-E-E”
Signalman 3rd Class (Surface Warfare ) Weathers_USS Dubuque LPD-8 and USS Juneau LPD-10. 1997-2000
good one...now have change.. alpha brevo charlie etc
So before Charlie came Cast...
Surprised to see the red meatball signal being used during this era of being at war with Japan.
It is the first time i have seen a signal with three letters, for instance "BAD". I couldn't find this rule in the book "INTERNATIONAL CODE OF SIGNALS" by IMO... Why?
Because you are looking at a different edition I'd guess.
Herman Wouk brought me here
May I use a short sample of this film on a video on my channel? I'm talking about Morse Code and will teach how to make it using an Arduino board and simple programming. It will be spoken in Portuguese. Please let me know if its possible. Thanks so much!

@@PeriscopeFilm Thanks.
This must’ve been before the phonetic alphabet. Or am I missing something? H = hotel. Where did they get hypo?
Navy Signal Corps? "Skivvy wavers", si'l vous plait!
Blinker gun message is “BT send boat for men. K”
Why coast guard music is playing??
They’re Coast Guardsman as stated previously. The shield on the right sleeve of their jumpers is the distinction between USCG and USN. We still wear that shield on our dress uniforms.
👍

Superb! You're the generation of Signalmen before me, but we still kept-up these 3 methods in my time (70s & 80s)......
Blinker Gun message = Send Boat for Men k
bravo ( _ . . . )
Really? No former singnalmen are going to translate this semaphore message.
I’ll do it. 1986 to 1992.
“BT Good form makes good signalmen”
Dan Jarvis I still talk to several of the guys I served with on the signal bridge of USS Lynde McCormick, an Adams class destroyer. They agree that the three forms of communication we learned are like riding a bike and although we’re a little rusty we still can do it.
The signalman “A School” was a relatively short one. Around nine weeks if I’m not mistaken. In that time we had to learn the three methods of communication. We trained differently for each one and I believe we spent a few weeks on semaphore then lights then flag hoist.
In addition to the three forms of communication there was many things to learn about the execution of the flag signaling. There was also schooling on how to read certain publications and break signals as well. It was a great rating and when I heard they did away with it around 2003 I was a little surprised. It seems like a lot to dump on the quartermasters who already had their hands full.
When someone arrived in the fleet after schooling it really didn’t matter how well they did there, they were as green as spring grass. It definitely took some time doing it every day for real until you could build up to speed and confidence required. I had a great instructor and I remember what he said and I use it everywhere. He said when you get to your ship there will definitely be a stand out, one who really knows his stuff. That’s the guy to beat. Don’t be an ass about it and don’t expect anything for it just tell yourself you’re going to be better than the best.
Dan Jarvis It’s no problem at all. I actually enjoy talking about it to anyone willing to listen. I’m sure you know the story. In a couple weeks I have my annual check up at the VA outpatient. I will always find guys still sitting there after their appointments talking to one another about the things they’ve seen and done. There truly is a brotherhood among veterans and I’m proud to be part of that.
@@danjarvis6980 Dan, you'd be amazed......we ain't all dead yet.....we're still around. Piece of cake to read this......
Thanks, Sir! By the way, I've found it weird the way he did the O letter (it looks like his right arm is not enough inclined).
And I thought the internet was complicated...
3rd Class Signalman. 1975 to 79. Remember the International Code of Signals HO-102???
1975.......You must've trained as an Signalman in San Diego? Wasn't that the USN Signal School back then?
@@mackan-kf4tg Yeah signalman "A" school in San Diego. Jesus, that was 45 years ago!!
I was stationed on the Uss Oriskany cva-34 then after it was decommissioned, went to the Uss Paul F Foster DD-964.
@@maddmaxx5384 I remember Pub 102 very well. CODE MJF, "Patient has diarrhea with stools like like rice water". SM 1983-2004
@@mackan-kf4tg Yes San Diego.
You realize that there is no such thing as a USN signal Corps, right? There was a Signalman rating (enlisted job specialty), now merged into Quartermasters. One of many, including traditional radiomen. Only the Army has a Signal Corps.
send boat for men k
"Navy"
To make a french battle flag simply rip off the blue and red sections and fly flag.
Im not good at talking to women, but navel ships that's easy.
Why do you put a counter in the middle of the screen. To distracting.
Here's the issue: Tens of thousands of films similar to this one have been lost forever -- destroyed -- and many others are at risk. Our company preserves these precious bits of history one film at a time. How do we afford to do that? By selling them as stock footage to documentary filmmakers and broadcasters. If we did not have a counter, we could not afford to post films like these online, and no films would be preserved. It's that simple. So we ask you to bear with the watermark and timecodes.
In the past we tried many different systems including placing our timer at the bottom corner of our videos. What happened? Unscrupulous TH-cam users downloaded our vids, blew them up so the timer was not visible, and re-posted them as their own content! We had to use content control to have the videos removed and shut down these channels. It's hard enough work preserving these films and posting them, without having to spend precious time dealing with policing thievery -- and not what we devoted ourselves to do.

it irritates me that they are not using N.A.T.O alphabet
??? This is way before the NATO alphabet.......the phonetic "coming in line" with NATO was in the late 1960s......up till then it was the Yanks/Brits/Canucks/Aussies/Kiwis and a few other English-speaking navies that used the old "Alfabet" (I think the UK Commonwealth navies i.e., South Africa/India/Pakistan/Singapore/Malaysia, etc, etc) also used it......
