ORIGIN OF DX

DX is allegedly an early telephone term for distant exchange. It is also defined in Funk & Wagnall's as Distance.

ORIGIN OF MAYDAY
Opinions From The Internet


Why do ships and aircraft in trouble use "mayday" as their call for help? This comes from 
the French word m'aidez - meaning "help me" - and is pronounced "mayday." (Note: not 
exactly.... it's pronounced "med-ay", but close enough)

ORIGIN OF DE
Opinions From The Internet


Does anyone know how and why the "de" is included whenever the first name is used.
....as in "73 de Yab". I know "de" is Dutch for "the", but maybe that has nothing to do with it.

Close...'de' is Spanish for 'from.' Ham shorthand. 73 from Yab. An artifact of CW usage.

All wrong, "de" comes from the french!!!!!!! language and has the translation to "from" 
and "of" in the english language. -- odo



ORIGIN OF CQ
Opinions From The Internet


Let's turn to page 4 of Baarslag's Famous Sea Rescues (formerly titled: SOS To 
The Rescue): "By 1904 a number of ships in the trans-Atlantic trade were equipped
 with wireless telegraphy. The British operators were nearly all landline telegraphers 
who had left railroad or post-office keys to go to sea in the newly opened field. They 
brought along with them not only their Morse code but also many of their telegraphic 
abbreviations and signals. One was the general call - CQ, which had been used to 
attract attention of all operators along a wire. It preceded the time signal in the morning 
at 10 o'clock and also all notices of general importance. CQ went to sea and became a 
general call to all ships."

A couple paragraphs later, "Early in 1904 the Marconi Company, realizing the desirability 
of some universal distress signal, filled the need by issuing the following general order: 
``It has been brought to our notice that the call `CQ' (All Stations) while being satisfactory 
for general purposes, does not sufficiently express the urgency required in a signal of distress. 
Therefore, on and after the 1st of February, 1904, the call to be given by ships in distess, 
or in any way requiring assistance, shall be `CQD.' '' "

To me, this implies that prior to 1 Feb 1904, some ship did use CQ as a distress call, 
and possibly her calls for help didn't draw the needed attention. (This was before the 
twice-per-hour Silent Periods were created - 600m was pure bedlam, and a CQ 
would have gone unheeded.)

For more radio history, visit your local research library. But please don't make up "facts." 
(Am I the only one who believes that questions concerning radio history should be 
included in the amateur exams?)

ORIGIN OF 73
Via Louise Ramsey Moreau, W3WRE and Charles A. Wimer KC8EHA

The following is from Louise Ramsey Moreau, W3WRE:

"The traditional expression "73" goes right back to the beginning of the landline telegraph 
days. It is found in some of the earliest editions of the numerical codes, each with a different 
definition, but each with the same idea in mind - it indicated that the end, or signature, was 
coming up. But there are no data to prove that any of these were used.

"The first authentic use of 73 is in the publication The National Telegraphic Review and 
Operators' Guide, first published in April 1857. At that time, 73 meant "My love to you"! 
Succeeding issues of this publication continued to use this definition of the term. Curiously 
enough, some of the other numerals used then had the same definition as they have now, 
but within a short time, the use of 73 began to change.

"In the National Telegraph Convention, the numeral was changed from the Valentine-type 
sentiment to a vague sign of fraternalism. Here, 73 was a greeting, a friendly "word" between 
operators and it was so used on all wires.

"In 1859, the Western Union Company set up the standard "92 Code." A list of numerals 
from one to 92 was compiled to indicate a series of prepared phrases for use by the operators 
on the wires. Here, in the 92 Code, 73 changes from a fraternal sign to a very flowery "accept 
my compliments,"which was in keeping with the florid language of that era.

"Over the years from 1859 to 1900, the many manuals of telegraphy show variations of this 
meaning. Dodge's The Telegraph Instructor shows it merely as "compliments." The Twentieth 
Century Manual of Railways and Commercial Telegraphy defines it two ways, one listing as 
"my compliments to you"; but in the glossary of abbreviations it is merely "compliments." 
Theodore A. Edison's Telegraphy Self-Taught shows a return of "accept my compliments." 
By 1908, however, a later edition of the Dodge Manual gives us today's definition of 
"best regards" with a backward look at the oldermeaning in another part of the work 
where it also lists it as "compliments."

"Best regards" has remained ever since as the "put-it-down-in-black-and-white" meaning 
of 73 but it has acquired overtones of much warmer meaning. Today, amateurs use it more 
in the manner that James Reid had intended that it be used - a "friendly word between operators."

I hope that this helps you in some way.... 73, Charles A. Wimer Amateur Radio Call:

Actually "73" was a term the old telegraph operators would use back in the old west days. 
It meant that they owned a Winchester 1873 rifle (their most prized possession) and that 
when they died they would give it to the other operator. Hense '73' meant I will will you 
my 73 rifle. '73s' meant you had more than one rifles that you would give to them (they 
were a really good friend.).

Hello,

It's a nice story, but it has no basis in fact. The actual source of "73" and "88" was the list 
of numerical abbreviations used by wire telegraphers. These abbreviations were used in a 
manner similar to Q signals today. Here's a partial list of number abbreviations: 

1 – Wait 2 - Important business 3 - What is the time? 6 - I am ready 7 - Are you ready? 
12 - Do you understand? 13 - I understand 14 - What is the weather? 17 - Lightning here 
19 - Form 19 train order (used by RR) 21 - Stop to eat 23 - All copy 24 - Repeat this back 
30 - No more, end 31 - Form 31 train order (used by RR) 44 - Answer promptly by wire 
73 - Best regards 88 - Love and kisses 92 - Deliver promptly 134 - Who is at the key?

Note that American Morse was used by landline telegraphers. The signal "30" in American 
Morse is "..._. ____" (zero is an extra long dash). This was corrupted into a single character, 
"..._._" which is usually thought of today as SK or VA, with the space between letters removed.

ORIGIN OF Q, R, X, AND Z CODES
----------------

TELEGRAPHIC CODES OF MORSE AND MEN by Kenneth Brown G0PSW

The first line telegraph message is thought to have been sent from Washington to Baltimore 
in May 1844 by Samuel Finley Breeze Morse, (1791-1872). He is said to have tapped out 
the message, "What hath God wrought?" using a code of interrupted signals which he and his 
associate Alfred Louis Vail, (1807-1859), had developed some years earlier. After this 
momentous achievement and following the founding of Western Union in 1856, coast to 
coast telegraph lines were quickly installed and it then became commercially possible to 
send and receive telegraphic traffic by line.

Since then and with an eye on faster speeds of transmissions and higher accuracy, newspapers, 
railways and post offices made great use of the telegraph to provide their customers with speedy,
 economic, personal and commercial communication. This also paved the way for transmitting 
traffic by radio from the late 1890s following successful experiments by Marconi.

One way of speeding the flow of traffic was to operate an agreed set of short codes to replace 
well-known sentences or phrases but at that time there was no common national or international 
standard. The first of many conferences to discuss and try to resolve this issue was held in the US 
in April 1857, culminating with the release of the National Telegraphic Review and Operators' Guide. 
This Guide makes the first authentic reference to the well-known greeting 73; at that time meaning 
love and kisses. 'Later editions kept this definition but, as time went by, the meaning of 73 changed 
from a Valentine type of greeting to a vague sign of operators' fraternalism.

Western Union, in 1859, set up the Standard 92 Code. Replacing common sentences and phrases 
with selected numbers between 1 and 92 the message was telegraphed to a distant station. At the 
distant end the numbers were decoded and a plain language version delivered to the recipient. 
The definition of 73 changed yet again to a very flowery accept my compliments. From 1859 to 1900 
the many telegraphic manuals show variations of this meaning. Each major telegraph and railway 
company had its own distinctive telegraphic codes. Since there was no agreed standard all were 
different and, as a consequence, there was much confusion in communicating with different networks.

During this time there were even two alphabetical morse codes the American and Continental 
(European) versions. Although there were basic similarities there were also some major differences. 
This, combined with the multiplicity of telegraphic codes, caused confusion and made communication 
with and between US establishments particularly difficult.

The US 1908 Dodge's Manual gives today's definition of 73 best regards. Other Dodge numbers 
were 88 love and kisses, 55 lots of success and 99 get lost (probably unofficial).

Also, in 1908, the British Post Office, despairing of action to agree an international code of 
abbreviations, issued its own list of two letter abbreviations intended for use between British 
coast stations and ships. The list, published in the PMG's Instructions to Wireless Telegraphists, 
included abbreviations RA to RZ and SA to SF. The next International Radiotelegraphic Convention, 
held in London in July 1912, adopted and extended the GPO abbreviations. Q was added as the 
first letter and so the Q code was born. The new code now ran from QRA to QRZ and QSA to 
QSX. On 1st July 1913 the Q code finally became an official international information code, updated 
as changing circumstances demanded to include new codes relating to such matters as aviation 
and maritime.

Some time later came the Z code, running in parallel with the Q code. This originated as a company 
code of Cable and Wireless with application limited, in the main, to high speeds machine morse 
operating at speeds of typically 120wpm. Widely used by many countries, including Germany, the 
Q code and Z code continued in use throughout the war. After the war high-speed morse 
became less widely used and was replaced by other forms of traffic communication such as RTTY and 
facsimile. The Z code, therefore, gradually went out of fashion and slowly disappeared. Examples 
of the Z code include ZAA you are not observing circuit discipline, ZAN we can receive 
absolutely nothing, ZST send slips twice, ZAP acknowledge please and there were lots of others.


So the Q code became the standard international military and civil telegraphic letter code used in 
CW communication. (Sometimes, incorrectly, even in R/T). Published as an operators' manual, 
there are separate sections available to deal with various areas of communication. Some less well 
known examples of the Q code used by base stations of the British Army included QAU followed 
by QHU,meaning I am waterlogged, I am about to jettison fuel; AS5 generally followed! Even less 
well known is QGG send the pony by the next train.

Widely used by radio amateurs operating CW, today's Q code has slightly different meanings but is 
still very similar to the 1912 version. One of the great benefits of using the Q code is the pleasure in 
being able to communicate with overseas operators who may not be fluent in the English language.

In conclusion, it is sad fact there will be no successor to the Q code; no longer is the morse code 
taught to Royal Navy. Data stream transmissions have displaced morse and taken over everyday
communication such is the march of time.

ORIGINS OF ROGER WILCO

Incidentally according to the “Morris Dictionary of Word and Phrase Origins” by William and 
Mary Morris(Harper Collins, New York, 1977, 1988). 

ROGER -- "in the meaning of 'Yes, O.K., I understand you -- is voice code for the letter R. 
It is part of the 'Able, Baker, Charlie' code known and used by all radiophone operators in the 
services in the 40's - 50's. From the earliest days of wireless communication, the Morse code 
letter R (dit-dah-dit) has been used to indicate 'O.K. -- understood.' So 'Roger' was the 
logical voice-phone equivalent." 

Also from “I Hear America Talking” by Stuart Berg Flexner (Von Nostrand Reinhold Co., 
New York, 1976).“Roger! A code word used by pilots to mean ‘your message received and 
understood’ in response to radio communications; later it came into general use to mean ‘all right, 
OK.’ Roger was the radio communications code word for the letter R, which in this case represented 
the word ‘received.’ ‘Roger Wilco’ was the reply to ‘Roger’ from the original transmitter of the 
radio message, meaning ‘I have received your message that you have received my message and 
am signing off.” Wilco implies "I will comply"

Then of course there is the "Roger Beep" (Di-Dah-Dit) which legend has it was innovated by the 
Space Missions as a quick way to "Roger it" No source for this "but have it on good authority - 
by a guy who was there" hi hi.

From the DX Reflector

Ok, I have heard and seen a half dozen explanations, now heres one from one who has "Been there-
Done That". "Roger" in both military and government communications definitely came out of the old 
cw days(and yes I did send/receive cw messages at the beginning of my career). The "R" was sent 
as a confirmation of receipt of a message,or a portion of a message. "R" was used, not "QSL". 
In voice communications , it thus became "Roger". Even in front-line operations such as by 
forward observers (I did that too). We used Roger and Negative You had to be completely 
confident in what you were sending or receiving after all, it could , and often was, life or death 
as to what got thru the communications lines. 

I cringe almost everytime I hear any military movie communications. WILCO means: I will 
comply with your orders. OVER means I have finished my transmissions and turn the channel 
over to you to transmit. OUT means I have completed transmission and am completely finished 
and turning off my rig. So you can see why I cringe "Roger Wilco Over and Out" WHAT DID 
HE SAY????

ORIGIN OF THE PROSIGNS


From the 1969 ARRL "The Radio Amateur's Operating Manual"

Many of the expressions and procedure signals still in use in radiotelegraph had their origins in the early days of the landline telegraph - long before Marconi sent his letter "S" across the Atlantic. In sending formal messages by CW, the first thing a beginner hears is "don't send punctuation. Separate the parts of the address from each other with the prosign AA." This is ironic, because in the American Morse Code the sound didahdidah is a comma and was doubtless the origin of our prosign. Originally, a correctly addressed letter was punctuated with commas following the name and the street address, each of which was (and still is) on a separate line although the commas have been dropped, even in mail addresses on letters. The comma was transmitted by Morse operators and thus, AA came to mean that the receiving operator should "drop down one line" when sent after each part of the address and it is so defined in the operating manuals of the time. Our familiar prosign SK also had its origin in landline Morse. In the Western Union company's "92 code" used even before the American Civil War, the number 30 meant  "the end. No more". It also meant "good night". It so happens that in Landline Morse, 30 is sent didididahdit daaah,the zero being a  long dash. Run the 30 together and it has the same sound as SK. 

-Louise Ramsey Moreau W3WRE/WB6BBO

-------------------------------------

Where Did They Come From? The end-of-message signal, AR comes from the American Morse letters FN, meaning 'finish'. SK, from the American Morse 30, meaning half-past the hour, the end of an operator's shift. ES, for 'and' from the American Morse symbol for '&', used extensively in written English in earlier times. And when old-timers send a long dash for 'zero', they are actually sending the correct American Morse symbol. History casts a long shadow.

-------------------------------------

Procedural Signals (Prosigns) for Morse Code
C Q - Calling any station (does any ham *not* know this one?) 
AR - over, end of message 
K - go, invite any station to transmit 
KN - 'X' go only, invite a specific station to transmit 
BK - invite receiving station to transmit 
R - all received OK 
AS - please stand by 
SK - end of contact (sent before call) 
CL - going off the air (clear)
