Small correction. The communication method described at 4:50 isn't simplex; it's half-duplex. Simplex is one-way only, period. Half-duplex is two-way; but only one at a time. Full-duplex is two-way; two at a time. Simplex communication would render one ship a permanent receiver and the other a permanent sender.

@christosgklezos
@christosgklezos Год назад
Actually it is wrong. What is demonstrated at the video is indeed simplex and full duplex. Half duplex is when you have a shore station that communicates with a ship radio that is of low complexity typically handheld or small craft where you only have one antenna. At that point you can’t use full duplex as both stations need 2 antennas to use full duplex. However what happens is you use the channels that are for use in full duplex and the ship station switches frequencies between transmission and reception. When you push the push to talk you use the ship transmission frequency and the shore station can hear you and as soon as you release it you switch to the shore transmission frequency. The result is the same experience as a simplex, however you can use the radio on the channels that are programmed for full duplex
@Draftmission
@Draftmission Год назад
@@christosgklezos Nah, the result isn't the same experience as simplex. Simplex is by definition one way only. If you can transmit and recieve, but not at the same time, it is half duplex. If you use 2 channels and 2 antennas you can experience full duplex.

@scarletlightning565
@scarletlightning565 Год назад
As stated, duplex channels only work when both stations agree on who gets to transmit on each half. Aircraft get around the issue by using simplex combined with doctrin and discipline. Any FAA or CASA (US or AU, others might differ) licenced pilot is required to be trained specifically in the use of aviation VHF which includes knowing the standard brevity phrases, structure and pattern of coms. Basically its a call and response "who im talking to, who i am, what I want" system. All pilots are expected to show discipline and not make unnecessary or overly long transmissions. Problems do occur but they're very rare. Plus using simplex allows aircraft to communicate directly without going through a ground controller, very useful when there isn't one (middle of nowhere or small airstrips) or one aircraft is out of range of the controller and another repeats the calls for them

1:14 - Many people don't realize, but not only does "SOS" not stant for anything in particular - that three-letter combination is *NOT EVEN THE ACTUAL DISTRESS SIGNAL* . You see, morse code requires pauses to indicate the end of one letter and the beginning of the next (ideally exactly long enough that another dot could fit in there). The actual letter sequence "SOS" would have such pauses, but the distress signal does NOT - the entire distress signal has the rank of a single letter, comprised of nine symbols stringed together with particular pauses. Funnily enough, you got this detail just the wrong way round, for BOTH the international distress signal AND the older CQD: While the distress signal as a whole is just one huge pseudo-letter (but you erroneously depict it with pauses), the CQD signal was a "shorthand" comprised of three distinctive proper letters, and therefore should have the letter separator pauses (which you erroneously omitted).

Half-Duplex voice channels users can use "Over" after each party is through talking, much like a period in a written sentence. That gives a chance for each party to use the channel as needed without collisions. This protocol is sometimes used in CB radio channels. It also minimizes the training needed to use half-duplex voice channels.

Um, "range of 20/30nm" confuses me, and not just in a "I'm an American, decimals are weird" way. "nm" is "nanometers", as in 1/1,000,000,000 of a meter. Even if you meant to say "mm", that's still "millimeter", which puts the range to about an inch rather than one thousandth of an inch, that's still a lower range than turning your head and talking.

When I was at sea (70s), one-way only transmission was called broadcast. Two-way alternating on the same frequency was simplex, and two-way simultaneous on a channel-pair was duplex. Looks like my radio school got it wrong. 😑

I looked it up. Depending on the domain, it's sometimes called "simplex" and sometimes "half-duplex". I knew it as "half-duplex" as well, but apparently, in the domain of ship radio communication, the term "simplex" is used.

The communication is not "simplex", is "half-duplex". Simplex is the radio station you tune in your car. You cannot transmit. Half duplex is when both parts can transmit but not at the same time.

In amateur radio, we would consider it simplex as well. Half-duplex is more of a term when you are dealing with wired data communication like serial.

“You can both here anything on the channel”… Sadly yes. I work for the port authority of two ports in North Germany. For some ascinine reason our working channel is channel 15. The same channel as Swinouijsce Port and most ships use it as a working channel on board. So basically on some days (good conditions) we have constant ,for us unimportant chatter’ just droaning away. And cause our masts are more high powered we can hear them but they can’t hear us.

I was an AB on watch on a sea going tug pulling a loaded sea going bulk barge headed to Puerto Rico. The mate was making passing arrangements with a ship and the mate said see you red to red. The the ship was foreign and the mate there was heavily accented speaking English. I idly said after they talked something like I wonder if he really understood the mate replied we'll if he didnt that's his problem. Hmmm the ship was a hell of a lot bigger and with the barge we were slow to maneuver so seemed more like our problem. Seemed to me like saying Port to Port or Starboard to Starboard would be more prudent.

"GOLF" is actually rarely used in practice, as well as most of the signal flags nowadays. I guess "BRAVO" could be mentioned as a flag hoisted any time a vessel is bunkering fuel or discharging sludge.

I get the sense that you don't really need to memorize frequencies with maritime as they use channels that correlate to frequencies, similar to TV and some walkie-talkies. Aviation and AM/FM radio (at least in the US) use frequencies. As for learning them, I'd suggest making yourself a cheat-sheet, you'll learn the ones you use often fairly quickly just by using them.

@@quillmaurer6563 Yeah, you never need to know that ch 16 is 160-whatever-point-something unless you're tuning it to monitor it on a scanner or one of the imported open-tuning handhelds, which are not legal to transmit from on these frequencies. More important to know which of the other channels are legal to switch to, in a given area, to continue a conversation.

With the launch (chartered by the shipping agent for crew transport) unable to locate our ship in the fog at Galveston, we incurred the wrath of the Coastguard by attempting to contact the ship on channel 16. Normal practice had been to make contact on 16 then change to a clear channel. With the threats of prosecution, we had no choice but to head back ashore and arrange overnight accommodation for the other officers and crew.
@cc-to
@cc-to Год назад
Assuming that was Galveston TX: for some time now the US has reserved 16 for urgencies and has set aside 9 as the ship-to-ship calling channel. Vessels not offering emergency response services may (should?) not even be monitoring 16. I believe this is US only; certainly here in Canada (which has its own setting on VHF sets, since we've given a different set of freq's to the railroads) general calling *and* urgencies remain on 16. Your launch operators seriously should have known this.

Trivia: Not only does SOS not stand for anything, the morse code referred to as "SOS" is sent as one string of 9 dits/dahs. So it isn't the letters S-O-S, as individual letters are separated by a short space. Instead, the same string of 9 could be broken up as IJS, VGI, SMB, or others.
