Wire signal
# Wire signal

A wire signal is a brevity code used by telegraphers to save time and cost when sending long messages. The best-known code was the 92 Code adopted by Western Union in 1859. The code was designed to reduce bandwidth consumption over telegraph lines, thus speeding transmissions by utilizing a numerical code system for frequently used phrases.

## 92 Code

Several of the codes are taken from The Telegraph Instructor by G.M. Dodge. Dodge notes:

    Other numerical signals are used by different railroads for different purposes, for instance, the signal “47” upon some railroads means “display signals”; while the signal “48” means “signals are displayed”. The numerals “9” and “12” are frequently used for “correct”. Other numerals are used for the different officials’ messages, agents’ messages, etc.

Codes that are not listed in the 1901 edition of Dodge are marked with an asterisk (*).

| 1* | Wait a minute. | 25 | Busy on another wire. |
| - | - | - | - |
| 2 | Very Important. | 26* | Put on ground wire. |
| 3* | What time is it? | 27* | Priority, very important. |
| 4 | Where shall I go ahead? | 28* | Do you get my writing?. |
| 5 | Anything? (Have you business for me?) | 29* | Private, deliver in sealed envelope. |
| 6* | I am ready. | 30* | No more - the end. |
| 7* | Are you ready? | 31 | Form 31 train order. |
| 8 | Close your key, stop breaking. | 32* | I understand that I am to .... |
| 9* | Priority business. Wire Chief's call. | 33 | Answer is paid. |
| 10* | Keep this circuit closed. | 34* | Message for all officers. |
| 12* | Do you understand? | 35* | You may use my signal to answer this. |

| 23* | All stations copy. | 92 | Deliver Promptly. |

In the above list, the numbers 19 and 31 refer to train order operations whereby messages from the dispatcher about changes in railroad routing and scheduling were written on paper forms. Form 19 was designed to be passed to the train as it went through a station at speed. Form 31 required hand delivery for confirmation.

### Contemporary usage

Today, amateur radio operators still use codes 73 and 88 regularly, and -30- is used in journalism, as it was shorthand for "No more - the end". The Young Ladies Radio League uses code 33 to mean "love sealed with friendship and mutual respect between one YL [young lady] and another YL" or simply "hugs." A once-used but unofficial code 99 meant "go to hell." The other codes have mostly fallen into disuse.
