They didn't. In the 40s (looks like 40s equipment to me) they did have bugs, keys that automatically generated the fast dits, but where you manually had to send the dahs. Might be that they hid a keyer somewhere and do use a modern paddle, i can't tell.

Transmitters of this era didn’t have electronic keyers as today’s transmitters do. Electronic keyers transmit Morse code dots and dashes automatically. Navy operators would either use a straight key like in old western movies, or what was called a Bug. Bugs were manufactured by a company called Vibroplex. Most Navy operators were proficient using the Vibroplex Bug. With the Bug keyer, dashes were sent by depressing the one side of a “paddle” and dots by depressing the other side of the paddle. The dots were created by an oscillating or vibrating contact, thus the name Vibroplex. The Vibroplex Bug is still made today and largely used by amateur radio operators. This type of key takes considerable practice to master, and has a distinct radio signal. It allows radio traffic to be sent clearly at a considerably higher word per minute rate than a straight key. WW2 Vibroplex Bugs are quite collectible today, as they performed a great service by the operators using them to help the Allies win the war.
When in went in the Navy in 1970 I went to radioman school and the first few weeks was spent learning sending/receiving Morse code and typing. I got pretty good but when I got assigned to my ship (USS Kitty Hawk) there wasn't a key in sight, it was all teletype.
The problem is getting the dah's length correct and consistent. I had my novice when I was 15, and had a pretty good fist with a straight key. The first time I tried a bug, it was pretty funny. Took a month or so of practice before I did a QSO on the air, and even then I wasn't too happy with myself. Anyone know what the WPM that a Navy radio net ran at?
The Army Institute Basic Radio Code training records went from 5 wpm to 16 wpm. I want to say a proficient op would run 18 wpm with great efficiency. ARRL Extra Class when I got my ticket 25 years ago was 20 wpm, with not much efficiency!
@@ericcommarato7727 I didn't have a receiver with a BFO in it, so i bought a code record from Allied Radio in Chicago and taught myself the code well enough to pass my novice test. By then I had an old BC348 and a DX20. I later traded the 348 for an HR10 that worked a lot better.

Presumably during WW2 most radio signals were encrypted in a secure office before being passed to the radio operators for transmission? Did the Allies use a mechanical system, like the German Enigma machine, or code books of some kind? Also, did the US and British navies use the same codes when operating together?
AC: Both manual coding from books/tables as well as machine decoders were used in WWII. Machine decoders became prevalent for routine use by the middle of the war. The NSA museum in Maryland has examples. You can see them on their website.
"During non-combat operations." Honestly, I would love it if they had played records during combat operations. I suppose it wouldn't really do for practical reasons, plus it would've been so noisy at those times that music probably would've been pointless. Still, who doesn't love the idea of a naval battle with a live soundtrack? "I don't want to set the world on fire," sings Bill Kenny as you and your shipmates rain high explosive on _Jean Bart._

If USS New Jersey has working HF gear the two ships could make radio contact on 20 meters. 10? perhaps start a Scout "net" relaying messages with USS North Carolina. and other museum ships.
At 6:14 concerning the radioman mannequin who is seated at the receiving station: he should be uncovered and the headset (earphones) should not be placed on top of his ears. This was very fatiguing after many hours of receiving. Rather, they should be placed on his temples as most did where the hard Bakelite phones were much more comfortable and did not hinder the listening of CW (Morse Code) as the sound propagated to the ears through one’s head. If you ever watch the movie “Midway” from the 70’s, they got it right. Also, when describing a receiving station, the “typewriter” is called a “mill”.
A pity the USS New Jersey doesn't have its original radio equipment (I'm assuming it doesn't). The New Jersey received (and decrypted) the most famous message in US Navy history.
I love the collaboration between Battleship Cove & Battleship New Jersey. The history lessons are great.
I remember learning Morse code at Battleship Cove as a Cub Scout
It was USS Alabama for me in the scouts. I loved the trips were we stayed the night on the Lucky A.
Thanks and 73! Would like to see the New Jersey's radio rooms as well!
Yeah same here! Compare the latest iteration that the New Jersey was upgraded to .. to what we just saw in this video - 1946 state of the art.

BB = Battleship Brothers
How long were the SoDaks in mothball before being scrapped or turned into museum ships?
About 18-19 years. 1946-1965
What might be the maximum signal transmission range in miles if the Battleship had use of its most powerful transmitter to get a message out?
MY guess it depended on what HF frequency, the time of the day and what the sun spots were like back then.
Does New Jersey have an operational radio room?
3 in fact. We usually broadcast on Saturdays, when we can get people in that is.
