However, such "polar keying" (originally "polarized keying"), those are implemented as TRINARY since there is the state where no current is flowing in the loop . . . Welp then that means CW is a tertiary mode. Given a slice of RF spectrum space in which CW is being transmitted there are actually three states: Key down, key up and the noise between up n' down. OYeah, the noise matters as a "state". Morse code is definitely BINARY. Binary does not refer to the time or duration of maintaining either of two states. None of that really matters to any policy discussions. It matters greatly to those chat-roomers or morse-bloggers who MUST fill space with all kinds of miscellaneous dreck subjects reveling in the sanctity, efficacy, nobility . . .

![]() Can a person request to be tested by sending? My sending has always outpaced my receiving! 99% of people are that way. The FCC found that nobody ever failed a sending test if they passed a receiving test. So they decided why bother with sending. |

Can a person request to be tested by sending? It is my understanding that such a test can be administered as an accomodation. Same as someone might request a flashing light rather than audio tone, or a pitch other than the usual 750 Hz. My sending has always outpaced my receiving! Mine too. 73 de Jim, N2EY |

Unless you count disagreeing with him and proving him wrong as "being mean", you've been nothing but nice to him. Well, he probably thinks so! Whether he thinks at all is unknown. It's clear he has no shame, however, considering how he behaves here and all the Godwin violations. He and "F%$@ $%#k" Dick Cheney must be buddies. Mike Deignan had him pegged. Len's really ticked that somewhere, out there, somebody is having fun with ham radio. *Every Day*! If I'm not operating, I'm reading or surfing the web to learn about it. And I venture in here for a little mud wrestling from time to time too! 8^) What *really* ticks him, I suppose, is people having fun with ham radio and Morse Code... so I'll try to meet him halfway with a Morse code topic. His definition of meeting halfway is that you agree with him 100%. That is certainly possible... It's self-evident... So maybe we can ressurect this old one... I hear lots of Hams declare that Morse code is a binary mode. It is most certainly not. Depends how you define "binary". One state equals "0" or "off". The other state equals "1" or "on". You have to define "state". If "key up" and "key down" are the states, it's binary. Time isn't the factor you make it - look at how Baudot works. Certainly. But Morse code, which was invented as a human translated code, does not qualify to me as a 1 or 0 state. Here is my rationale: If the key is up, the radio is certainly not sending 0's. Doesn't have to. This brings up an interesting paradox... If the lack of a signal is a 0 state, then when no signal is being transmitted, you are receiving zeros until someone sends something. That's right. And a string of zeroes is interpreted as lots of spaces. I grant that a dit might be a 1. If a dah is 3 1's, why do we not send 3 dits. I either hold the key down longer or press the dah switch on my keyer. It sends out a longer pulse, not 3 1's. It sends three dits with no space between them. Describing the signal as how many 1's a signal is, or how many 0's indicate intercharacter or interword spacing is a method of translating the varying length Morse code signals into digital format. So? The basic element is one dit length long. Three of them together in the one state is a dah. Let us look at the situation. Is the Dit a "0"? No. Is the Dah a "1"? No. Is the space between characters a "0"? and the Dih a "1"? Oh wait, what is the Dah then? Oh, and what about the space between words? Key up is "0". Key down is "1". Also known as "space" and "mark", respectively. Unfortunately, there are two separate "1" states, and the zero state is not a constant thing. Doesn't have to be. It's a time code. There is the matter of time. A zero might me the space between letters, or one half of a dit. It might also mean the space between words. All different things. No. The characters are built from the basic elements, which are key up and key down, just like, say, Baudot RTTY. That Morse code can be turned into binary is not at argument here. It obviously can, just as images, emails and everything else we do on the computer. Are they binary because someone has written a program to turn them into strings of 1's and 0's? Their basic transmission form is binary, same as Morse. A non-binary code is one that has more than two *transmission* states, like QPSK. Which is typically implemented as 0, 90, 180 and 270 degrees shift. Four transmission states rather than two. It isn't binary, Depends on how you define "binary". and the way our noodles process it isn't binary. Different subject. Not really. If you look at the string of 1's and 0's that Doug posted as the binary result of my hypothetical CQ, is that something that you would recognize as that CQ? That string IS binary. I would recognize it easily. Why does the - and . method of typing out the code convey the information? the dashes and the spaces convey time information to the person looking at them. I'm counting more than two states here. It's not the simplest way, though. It shows the time differently. It's not binary. Most Morse operators with any skill (that excludes Len) process a complete character as one "sound". "didahdidit" is recognized as "L", in the same way that when you hear the word "cat", you think of the animal. The Morse operator does not think in terms of dits and dahs any more than a person thinks in terms of the consonant and vowel sounds (phonemes) making up "cat". Of course *really* skilled Morse ops hear entire words as units of sound. And at some level, they begin to think in Morse, just as fluent speakers of a language think in that language. Of course Len wouldn't know about that... The big question is: what does it matter if Morse is binary or not? Of course not! I thought it might be something better to talk about than whether Len thinks we're "jackboot thugs" tho'! 8^) Who cares what Len thinks? I sure don't. His behavior here has caused most of us to lose whatever respect we might have once had for him. His latest reply to K8MN simply reinforces that once again. 73 de Jim, N2EY |

Now if you want to continue arguing this inapplicable non-discussion, please go to rec.nonsense.angels.dance.on.pin newsgroup and live it up. Morse code is NOT high technology. It was devised out of a need to use very primitive electrical devices to communicate. Some 52 years after the first morse code was used, very primitive early radio technology used morse code to enable communication by radio. [that was in 1896 and began the Mythology of Morse some 109 years ago, before the invention of the multi-element vacuum tube and well before the first transistor] Put the subject to rest. RIP. And here, once again, we have Lennie dead-to-rights in yet another "Do As I Say, Not Do As I Do" rant. Lennie will be the first one to yell "You're not a moderator!", yet he has absolutlely no reservation about telling anyone else to shut up or to "take it elsewhere". Never mind that Mike never made such accusations or suggestions to Lennie. His right to "freedom of speech" notwithstanding, Lennie has no business here. He is not a licensed Amateur, has no practical experience in Amateur Radio, and he frequently demonstrates incompetence in matters of Amateur practice, policy and regulation. In short, he's a putz. 73 Steve, K4YZ |

I know when I was offered a Field Engineer job they were happy I would not have to study CW (I turned it down, the idea of paying my moving and transfer expenses rankled me) AFAIK the "technical agents" (used to be called engineers or technicians) still have to qualify at a minimum of 20 wpm text and 16 wpm code groups. The non-technical agents (used to be called Public Contact Specialists) and the clerical staff do not have to be code-qualified although I know several who are code-qualified from being licensed ham operators or once were monitoring station technicians. As far as relocation - when I hired on in 1967 they paid my transportation and moving expenses cross-country. It may have changed by the time that you were contacted. -- 73 de K2ASP - Phil Kane |

And a string of zeroes is interpreted as lots of spaces. And it means that information is being sent with no energy used in the sending. Hence the paradox. Of course if we are dealing in quantum matters, there is not as much paradox, except for why it is all 0's instead of a 1 here and there. I grant that a dit might be a 1. If a dah is 3 1's, why do we not send 3 dits. I either hold the key down longer or press the dah switch on my keyer. It sends out a longer pulse, not 3 1's. It sends three dits with no space between them. Only after you decide that the signal is digital for the sake of calling it a binary or digital signal. It isn't sent that way, and when you listen, you don't think of it that way. The only time you need to think of it that way is when you decide to do something with a computer, and need to translate the Morse code signal into something that the computer will understand.
