Split? What's a Split?

What is wrong with the mentality of the operators out there?
I'll admit as far as the license goes I have only been able to operate HF for a little over a year. That being said, I still know how to operate.
Working tonight the YW5M station who was working split, I could not believe the number of people who just could not figure it out. One guy became so frustrated he did what every operator with the mentality of zero would do and started causing harmful interference on the receive frequency. When the dumbbell finally figured out it was split and he was up three he did it there. Luckily everyone ignored him and he went away.
That being said though, I went on the receive frequency several times and tried to explain to the fellow hams that he was working a split freq, they could call him here all night long and he would not here but they didn't have a clue. Unreal.
Makes you wonder what's on the horizon...

Unfortunately, some hams don't have split.
Others don't even have RIT.
And still others don't have ears.
Try CW - it's not as bad there. 73

So you let others know its not nice to xmit on the receive freq -- by xmt on the receive freq --like the
zero mental operator???
Could you please splain yourself?

I think if you called it duplex, it would be more
understood. I know what it is, but that's only because
I've been a ham a long time.
Duplex is an easily understood term and one that is
taught regarding communications.
There always being the ten percent that don't get the
word. Duplex is where you receive on one frequency and
transmit on another. The station you are talking
with transmits on your receive frequency and receives
on your transmit frequency. This allows for
a conversation much like a telephone. The difference in frequency is dependent on your equipment set up and can be fairly close or for less sophisticated
equipment some distance away even on different bands.
The opposite of duplex is simplex where both station use the same frequency one at a time.
Not being a DX'er, I'm not sure what they do, but perhaps notch their recieve frequency as they are often
pretty close or perhaps,judging by the pictures I see in the mags, greatly seperate their transmit and recive antennas. At VHF/UHF, a common method is to have antennas of opposite polarity. That is the you receive on vertical and the other station transmits on vertical and you transmit horizontal and the other station receives horizontal.

How About let's place the BLAME where the FAULT LIES !
Wouldn't it seem reasonable to think that:
UNLESS the sought-after station or one of his helper ops said (IE:TRANSMITTED) something like "LISTENING UP TEN" (or "Three" or whatever) that it would seem LOGICAL to ASSuME that a station is transmitting and receiving on the same frequency?? Especiall if you just happened to drop in? To assume otherwise is not only "ERROR"-O-GANT, and disrespectful but in it's own way is contributing to the QRM by OMMISION (NOT) reporting that fact. (split operation)
Some BIG DX-piditions publish in print or on the web well in advance that they will be working split... and YES an experianced or seasoned DX-op might just naturally ASSUME, and go searching for the calling freq.)
HOWEVER NEW ops or the CASUAL non DXing Ham, who just happened upon the pile-up and might not be WISE to to way of the world of DX....why should they "KNOW" otherwise?
MAYBE they didn't have good elmers... maybe this is their first exploration into the world of DX... maybe (and I'm not saying it IS) it was the "WAY" they were told (on frequency) to work SPLIT that ticked them off enough to QRM (although that does NOT justify that behavior) Who knows???
WE mention (explain the theory behind) "SPLIT" operation in our GENREAL UPGRADE CLASSES, but we do not spend a lot of time on the subject... it's kinda one of those "niche" cliques... of the 37 in the class... maybe one or two will even CARE to chase the rare ones.
Dispite comments to the contraty, I would think you did the correct thing about telling them the station was listening on an alternate freq... if you did so QUICKLY and in a non confrontational (read that: NICE) way. Elsewise how would they know? you were trying to "clear / clean" up the frequency and make it more enjoyable for all.
For any listeners to then start QRMing was highly uncalled for.

Well, there are two problems with "policing" the DX's transmit frequency.
1) You're doing what you DON'T want the other guy to be doing, you're QRMing the DX yourself.
2) You're wasting your own time when you COULD be trying to make the contact.
Better not to play cop.
If he's a QRMer, fighting with him will only make him feel successful. Ignore him and he'll get bored.
If the guy doesn't know the DX is working split, he'll either figure it out by himself or he won't make the contact. Listening is an important part of DXing. If somebody doesn't have the listening skills to tell if a DX station is working split, then he'll be pretty unsuccessful over time. Finding the pileup once you hear the DX isn't exactly rocket science. Finding the DX if you heard the pileup first is a LITTLE harder but hey--that's not rocket science either.
That's why they make THAT knob the biggest...

I work Dx from time to time and I must say it usually is very enjoyable. Sometimes there are allot of problems with people on the wrong frequency during a split operation. Then the frequency police only add to the problem. Most operators realize in a short time if they are not hearing the station the DX operator is going back to that they are in error. The problem is a little more difficult if your receiver has the ability to monitor both frequencies at the same time. Icom calls this Dual Watch (not certain how the others label this feature.) When Dual Watch is active you can usually hear both sides of the exchange and it is mandatory to know where you are transmitting. A good operator knows before hand, but we all can make mistakes. How quick we realize it and make the adjustment tells how experienced we are at split operation. For anyone who is serious about being a better operator, the ARRL Operating Manual gives some good techniques for working Dx split on CW and SSB.

IMHO, quite a few do not listen. Why do you think everyone wants hf? To listen? I think not..that is there for the taking..anytime.
I have never heard a station running split that tx did not say it..or was not even supported by another station giving the info. I did run in to a situation where the split was changing, I guess as a pileup deterent, but I never did make that one.
Anyway..two ears,one mouth there is a reason for that set up. Somebody will help you out if you listen!
If you interfere cause you did not make the contact seems a little to anal retentate for me to grasp..but it does take all kinds to make a world.
If i mispelled something it was because I am running an ASC split, and I am not telling you what it is.
Good DX to all,
Terry

Easy - except for a handful of contests, the biggest way to QRL the most QSO's at one time. What you do is hear the station of interest say "up" (or "up 10" - doesn't matter), then you go up 5 khz and answer him. Of course you don't listen before you transmit (and if you claim you do, well, I just don't believe you), and when you don't get an answer, you go up 6 and try again. When this fails you go up 7, etc., until you're up about 25. At the same time another several hundred folks do the same thing, and you take out all the spectrum between the station of interest and the next 25 or so khz up. This works equally well on phone and cw. BTW, why don't they ever work "down 10"?

Anyone in a pile-up for VY is a novice DXer.
There are many novice DXers.
Also. Sometimes ops set up the correct split, but have their VFOs backwards. As a result, you can yell at them all you want, they don’t hear you.
Some day, you will be tuning across the band, find, a “rare” to you, DX station, and pounce on them before the pile builds. Then you’ll find out, the DX is split. Happens to everyone sometime.
And, sometime, you’ll turn your rig on, find DX that isn’t split, call, and call, and call, and call, and call… You eventually discover you are in split from the night before. No wonder the DX didn’t hear you, you are calling up 10!
Consider that, although well meaning, frequency police add to the QRM.
This has gone on since split was invented, few people “.. wonder what's on the horizon.”
Some might argue that it is very REAL instead of being “Unreal.” Unreal is if it NEVER happens in a pile up; especially a pile up for a RARE country.
Have FUN DXing.

It is understandable why the really "Rare" stations work split. However, it is happening so often that it causes unneeded QRM. I hear common DX on weekend holiday working split. It does not surprize me that they attract stations returning the QRM. I think it is true that attempts to police a frequency cause more trouble than help. I have noticed that most CW split is within the range of most RIT controls.

I'm not a "novice" ham. I've been a ham for over 12 years, and have worked a few dozen DX stations who were operating split. At first, it was mostly thanks to someone who was on their frequency who told me they were listening "up 5" or "up 10". Now, when I hear a DX station on 14.195, I listen for a few minutes to see if I hear anyone, ANYONE AT ALL, coming back to the DX station. If, after 5 minutes, I don't hear anyone, then I think it's safe to assume he's working split, so I go in search of someone calling him 5 or 10 up. At the very least, every other transmission should end with "up 5" or "up 10". Sure would save some grief (to those who understand what it means).
While we're on this subject, someone please explain to me the rationale behind operating split in the first place, please? If you're trying to work the DX station, you can't possibly be listening on the frequency where you're transmitting, which is very poor operating procedure (you have no idea if the frequency is clear or not). The DX station is also operating likewise, because he's not listening on his transmit frequency. Why bother to listen "up 5" or "up 10"? The frequency the DX is listening on (unless the DX is working a "spread" of frequencies) is just as likely to have trouble picking out a station as they were only occupying a single frequency!
Let's not even discuss the bandwidth the DX stations working split take up- (and some guys complain about the Wi-Fi SSB guys taking up a measly 6KHz, SHEESH!) If I had my way, working split would be made illegal. But that's my soap box...
Please, someone give me a -GOOD- reason for working split (and I'm not talking about repeaters here, just HF SSB)? I might change my mind.

There are two reasons a DX station who anticipates a pileup operates split. One good for him, one good for you.
1. For him: he can listen over a short range of frequencies above his and discern stations calling him with a sharp filter. If everyone were calling him on his freq all he would hear is a roar.
2. For you: You could never hear the DX station when he is listening for calls because of the massive QRM from everybody calling. You could never pick out which one was the DX station if everybody were all on one freq. Plus every qso would take five minutes to establish contact because it would take everybody that long to shut up except for the one he calls.
Thats my experience. I wish more of them would operat split. Also, you should always listen to the freq you will be transmitting on to call the DX to see if it is in use. Usually its in the middle of everybody else calling, but its good to give a quick listen just in case.

“Please, someone give me a -GOOD- reason for working split …? I might change my mind.”
Basically Web, because the DX station you want a Q with says listening up. But, you already knew that. As always, if you don’t like the practicse, don’t participate.
If you are ever at the bottom of the pile up, you don’t have to work split. But, when the DX is coming in 5x5 and the pile up is 5x9, few of the stations the DX calls will hear the DX.
Some of the DX, especially DXpeditions listen up and on their xmit. Many DXers also listen to the DX station and on their xmit. I find it easier to just listen on one VFO though. When the DX calls a station, I switch VFOs trying to find where the DX has shifted his receive to. Not much sense calling where the DX isn’t listening.
I’m pretty sure both of the Peter Island DXpeditions I’ve listen to worked split. Otherwise their Q rate drops way down.
With the Duce Island crews, the only op who didn’t work split was a rather new op, sloooooooowed things waaaaaaaaaaay down.
Have FUN

I guess most of us have at some time hit (or not hit!) the button and called the DX on his freq when we meant to call elsewhere. I know I have. Then someone saying 'RZP Split' tells you that you mucked it up. Of course, we all try to make sure that we look at the frequency display when we call, don't we?
Split operation really amkes a difference to the QSO rate of the DX station though. That's why it's used.
If you look at spectrum utilisation as a time/frequency spread function, operating split over not too wide a band actually improves spectrum efficiency in terms of Hertz-minutes. This is because more people get through in a given time.
An, no. It's not duplex operation. Some people call such operation half duplex, but more accurately, it's two frequency simplex.

It is not so much the "frequency police" as the "tuners" who get my goat on split ops. I work mainly DX and spend a lot of time and effort to find out EXACTLY where the DX station is listening before I call (else why waste the call).
Well, I find where he is working someone, move my TX frequency there fast, and call - but when I listen for him some guy/guys are tuning their amp/s on the DX station's TX frequency. The DX station may have heard me, but I don't know, so I call again - same story again, still tuning.
That is when I throw the OFF switch and go walk in the garden.
PLEASE FOLKS, TRY TO TUNE AMPS OR ANTENNAS AWAY FROM THE DX STATION'S TX FREQUENCY or the Q rate goes down into the pits.

"Please, someone give me a -GOOD- reason for working split (and I'm not talking about repeaters here, just HF SSB)? I might change my mind."
There are many. Most of them deal with working stations quickly. The only reason there is a pile-up is because lots of hams want to QSO the DX. So the DX is being courteous to everybody involved to do what it takes to work through the pile-up quickly.
1) Without split, the whole pile-up calls the DX on freq. The DX has to wait for the entire pile-up to die out before he can answer to ONE callsign. Working split, the DX station can call you the moment you're done sending your callsign. I've heard a good DX station work 2-3 QSOs while the stilly pile-up is still calling.
2) Without split, some stations will inevitably call the DX while he's responding to someone already. Mainly because they can't quite hear the DX (and shouldn't be in the pile-up anyway). The busted QSO has to be repeated. With split, this is far less likely.
3) In some cases, it is not legal for a DX station and a US station to use the same frequency. 40 meters, for instance, most DX countries are not permitted above 7.1 MHz. In the US, SSB is only permitted above 7.15MHz. Therefore, SSB DX on 40 meters, to be legal, MUST be split.
There are a few very obvious guidelines for working split.
1) It's always "up". This is a solid convention, just as solid as "LSB on 160, 80, 40, and USB elsewhere". No law, not even a gentleman's agreement, it's just the way it is.
2) If you can't hear the pileup, don't transmit. Whether the DX works split or not, make SURE you can hear the other stations calling him before you make a call. If you can't hear the pileup, then you certainly have not figured out where the DX is listening.
3) Once there's a DX pileup, quite frankly, the need to listen on your TX frequency is a bit moot. There's a pileup - that's not quite a QSO. You're going to drop your callsign on the pileup, not to interfere with it, but hopefully to be heard by the one guy you hope is listening.
4) DO listen on your TX frequency. ALL rigs with split capability can do this easily. Sometimes it's a "VFO A/VFO B" switch and sometimes you push a button to put the RX and TX freqs together, but you can always do it.
5) If you really want to work the DX, you'll switch from one freq to another to find the last station the DX guy worked, and set your TX right there, ready to be next.
Someone said that some hams cannot work split. It is true that some rigs can't work split - but they are exceedingly rare. In the 1960s and 1970s, before transceivers were the norm, everybody used separte RX and TX. They could all work split, very easily. The early Japanese hybrid tube/solid state rigs all had RIT, which gave you some split capability. And, for all of them, you could modify the RIT for greater bandspread. More than 10kHz is not required - split is usually 3-5kHz. Any solid state radio with a microprocessor can work split.
DXing takes some serious operator skill to do regularly and right. Dxers make the BEST emergency comms operators because they are the best at quick thinking.

It doesn't even have to happen on HF. A few years ago I was participating in an emergency drill. We were using a high level repeater. One station that was trying to pass traffic to us could hear the machine but couldn't get into it. So, he was transmitting simplex on the repeater output to someone else who could. I transmitted back through the repeater directly back to the first station.
You guessed it. This TOTAL LARDHEAD came on the repeater and kept asking, "Who are you talking to? I don't hear anybody else!" About three of us tried to tell him not to transmit during the silent periods after my transmission, because that's when the other station was giving his info simplex somewhere off in the sticks. Lardhead soon knew what was going on but just kept acting like a buffoon. "Well, I don't think you should try to use a repeater THAT way... I mean, if the other guy can't even hit the machine what's the use of doing it this way?" He disrupted what we'd thought was a pretty good solution to some communications from a fringe area before he finally moved along.

Well have been licensed for about 18 mos. Yes I know what split operation is-But!!! Why NOT give some of the blame to the DXer that rarely gives his call sign,qth,
and information and just expects you to know what the heck is going on. And then when you ask gets aggravated with you because you do not know. As for myself I have better things to do than sit there for 15 or 20 minutes and wait untill he or she finally gives out enough info so that I may call etc. without disrupting his or her 100 contacts an hour!!!!
So between all of the qrm,qrn,qsb on the band during a pile up there is also poor technique by the dxer to deal with along with maybe an accent or language barrier that makes it even more difficult.
Before you blame the person who does not know a dxer is working split question whether the dxer is giving out the proper announcement. What is the problem each time or every 2nd or 3rd time announcing split up three etc. Remember there is always 2 sides to the story.

First off, There are enough frequency police with out you helping. You going on the tx freq and telling folks to listen X kc's up, is as bad as them hollering on the rx freq in the first place. It is the responsibility of the operator to indicate he or she is operating split. Its not your job....
Second some folks use split because they can not legally transmit above a certain frequency and some hams can't legally transmit below a certain frequency, so the operate split from a foreign country to talk to folks in this country on split legally.
Third, if you need to have lessons in operating split ( duplex) then you need to either find the manual for your radio, or learn the purpose of the "split " button, or figure how to use the rit knob.
Come on folks, this ain't rocket sience, it transmitting on X freq and listening on X + 3 kc's , thats it.
Now go practice on a dummy load.

Now I finally know that today's newer generation "Qualified amateurs" are not "Qualified to be amateurs."
Changing the name from split operation to duplex for them to understand. Just pathetic, what in hell do they learn, they don't, they guess and hope.
Listening is the majority, listen, listen and do more listening. The split station shall give his receive frequency in time. Receive frequency, what's that?
Do you have any idea of what your transmit frequency will be when DX Joe gives his receive frequency?
ABSURD, plain and to the point, ABSURD.

Yes, you're right, there are always 2 sides to the story. The side you missed is that it's a LOT quicker for you to use your receiver and the internet to find all that information you expect the DX station to hand you on a silver platter.
Sorry, no sympathy here. You don't have to hear the split announcement. If you can hear the DX station working lots of others - and you don't hear the others - then you automatically KNOW he's working split. It's always UP, and almost always 3kHz. It's that easy. You MUST find the pile-up, otherwise you'll never know you got it right. LISTEN, LISTEN, LISTEN.
It is not up to the DX station to tell you where to listen, it is up to you to find out where the stations are who are working the DX, and adjust your transmit to match them. This is called operator skill, and is based 99% on the ability to listen.
It's not poor DXer technique if he's able to keep working through the pileup.
If there's a pile-up, you can bet the DX station has been spotted - go look it up and then you'll have the callsign, QTH, etc.
If you can't wait 15-20 minutes to work a new one, then I humbly suggest that DXing is not for you. Actually, if you learn to use the clusters, you won't be waiting 15-20 minutes.

Sorry couldn't respond for a while working afternoon shift. Yes I did transmit on the call frequency ONLY when the operator took a break and only for a couple of seconds. Wasn't trying to play cop just trying to help them out with their contact, I'll leave policing to someone else.

I'm not a DXer; I do like to catch a DX station now and then as I like to collect QSL cards, not contacts. After reading a number of replies there was one item mentioned but not repeated as well as I thought it should have been. Take a minute and Listen before you speak. Not just listen to the noise, but actually Listen to what the caller is saying and see if you can hear to whom he's responding to. If you can't hear a couple or three of the callers, you can usually bet your sweet bippie he's not listening on the same frequency. It's all about listening before you speak. This rare art form works well on 2-meters too.
How's that old saying go? "Be careful where you leap, still water runs deep".
That’s all, bye.

Jeez.
Ya got a computer. If you must, just poke it up on packet and read.
UP 5 means just that. QSL via xxxxxx means just that. READ the DX rags so you know what's going to be on and spend some of your own time working the ones YOU need. The right way.
You want ME to work 'em for you?? Probably not.
You wanna be a cop? Go ahead. Knock yourelf out. But for some common crap? Why bother. Go look for some better station to work.

all this wanna be a cop thing, hope it's not directed to me because that was the last thing on my mind. People were getting frustrated, I simply tried to help them, simple as that. What pissed me off was people qrm'ing with "I know you can hear me" ect, ect.

I could have cared less if I worked the station or not, couldn't exactly call it rare dx. I don't think it was wrong to try and help the people who couldn't figure it out. If someone doesn't tell you, how you going to know? Unless like some people on these forums who are experts at everything from the day of birth

DX stations who don't give their call signs regularly are lids - no ifs, no buts, they're lids! And I don't care who they are! Good DXers give calls frequently. Listen to ops like G3SXW, G3TXF, WA1S to learn how it should be done. It shouldn't be necessary to use the internet to find out who the mystery station is - and there are still a lot of hams without internet access.
The good DXers minimise the police problems by giving their callsign very often and the QSL route reasonably often. That way, they increase the Q rate.
Let's hope the KH7K expdition due for October goes well - that will just leave me needing KP1 for top of the Honor Roll!

There were DX stations long before the Internet and clusters. (And neither of those does much good for the mobile operator.)
It's the responsibility of the DX station to give that information over the air! Their CALL (I've heard DX stations go for over 25 minutes without giving their call) and whether or not they are working split, and what split (that only takes a second every few "contacts;" can't call them QSO's.)
That's just common courtesy, and at one time was considered good operating procedure. AND frequent QSL routing if that's necessary.
(Of course, there's the argument of qunatity over quality...)

I also see no big reason for split. The fcc regs don't state getting a good call rate as a good goal, that serves the dx station, that's all!
I do understand that part of it, but I don't care what the rate is, it takes up a lot more bandwidth, and to me sounds like a bunch of clowns, no better than jammed am cb. I mean people intentionally working a bit off of the split anyway, talking on the tails of others and all the other tricks.
The best dx operators I have heard run simplex and somehow divide the calls up into regions, letters or whatever, and it seems that they go through calls a lot faster. And it's easier to listen to for pure listening sake!
Then again I'm a bit jaded. I never thought a pileup contact was quite on the same level as a one to one cq-response type qso, that is what really gets me going.

Well well..I see no no reason to learn cw or work a splt.
Except for the fact that it teaches you exactly how to operate or how someone else might be..
Except for it teaches how to listen and what to transmit.
Except for everybody wants to help you learn it.
Except for it might take some gd effort.
Except for its outdated and we're all gonna die.
Except for I got nothing better to do with my spare time.
Except for the fact these OF's might be right.
Got nothing to do with the fcc.
I see no reason to learn cw
or work a split.
Support a slow cw net
(Man I went on a big tangent that time!!!!)

I would expect him to operate split, plus
I would expect him to go by numbers, plus
I would expect him to calll specific areas of the world
all at the same time.
I would also expect those wanting to work him to know how to follow his instructions.
I would set my alarm for 2 AM, if that's what it took, and rearange my personal plans as well.
I would hope to get through, eventually.
I would do this for North Korea and for Scarborough Reef, willingly. But nothing else.

Hey all:
I admit I had been standing on the sidelines for BPL (although I did
contribute a decent amount of money to the ARRL Spectrum Defense
Fund), however, it wasn't until I saw the ARRL's Video depicting the
actual interference that BPL generates that really made my blood boil
and got me to file my comments to the FCC.
Here is a link to the shocking video (PLEASE WATCH IT):
http://216.167.96.120/BPL_Trial-web.mpg
Here is an EASY link to let you file your comments about BPL:
http://gullfoss2.fcc.gov/ecfs/Upload/
Tick the top Docket: BPL 03-014
Then Click the Continue Button at the bottom of the page.
Then fill in the form with your comments and hit submit.
If BPL really goes through, I'll be putting almost all of my Ham
Equipment up for Sale -- although it'll probably be worthless except
for scrap metal and silicon.

That's why it's always best to listen, before jumping in and keying up the mic. This is especially true on HF. I don't know how many times I've stumbled across a DX station, only to listen for five or six minutes and learn that it's a DX net. The same also works when the other station is working split. If you take the time to listen, generally they'll announce they're listening on such-and-such frequency, or 'so many kc up'. Failing that, check DX Packet Spots on eHam. Chances are, someone has posted the necessary information and you'll know what the correct split is. As a fairly new amateur (licensed Dec. 2001), even I know this. To jump right in without listening is just plain rude and gets one labeled as a lid.

I 'spose your one of those guys who gets on the receive frequency and tells everyone else how to do it. (up....up.....spleet.....spleet....ad nauseum) We used to call you a DX COP but now I think it is probably a more colorful name maybe..........

(SPLIT?WHATS A SPLIT?) a split is where most radio police gather and totally wipe out the rare dx station by constantly shouting "UP UP,STUPID STUPID,UP UP YOU STUPID OPERATOR,I DONT BELIEVE THAT,UP UP UP ...they normally repeat this about 6000 times blanking the poor dx station out to everyone and they *NEVER* give there callsign................
SPLIT = RADIO POLICE = QRM OVER THE DX STATION.
if the radio police kept quite we might hear the rare dx stations callsign and his operating frequency instead of ( UP,DOWN,UP - STUPID MAN - DOWN,DOWN,UP - SPLIT SPLIT SPLIT

I don't think so, but I can come up with a few colorful names for people of your caliber fairly easy

"Duplex is an easily understood term and one that is taught regarding communications."
Duplex is an ambiguous term, that has (at least) two meanings in communications.
When operating "simplex", two operators take turns transmitting; neither transmits and receives simultaneously. This is half-duplex communication, meaning they have to take turns.
When operating "split frequency" in the absence of a repeater, two operators still take turns transmitting, but they use two different frequencies. One operator transmits on frequency F1 and receives on F2; the other receives on F1 and transmits on F2. This is *still* half-duplex communication. However, through the flexibility of language, this is also called "duplex", as contrasted with "simplex" in which both operators transmit on the same frequency.
In both cases, the communication is half-duplex--it goes only one way at a time.
"Duplex is where you receive on one frequency and transmit on another. The station you are talking with transmits on your receive frequency and receives on your transmit frequency."
This is one meaning of duplex. By this definition, running "split" is duplex; so is operation using a repeater.
"This allows for a conversation much like a telephone."
This describes "full-duplex," or simply "duplex," in which one transmits and receives simultaneously. This is *not* the same as a "split," but requires two separate communication channels, one in each direction. With the small frequency offsets used for a split, this is unlikely to be possible with practical receivers. Try operating full-duplex with a 10KHz split, and you'll hear only your own signal in the receiver--you can't eliminate your transmit signal (with realizable filters) if it's too close to the receive frequency. That's why repeaters have much larger frequency offsets (i.e., 600KHz at 2M).
And that's the annoying and unnecessary lesson in English-language and radio communication for today.
Oh, I forgot Duplex blocks. Or is that Duplo? ;-)

Get real! The only use of split is to gobble up twice the bandwidth to make people think you are important. It really just makes you look like a hog.
