 Tokuzo Inoue (call sign JA3FA) founder and still President became a licensed ham after amateur radio was again permitted in Japan in 1952. The first amateur radio built was a mobile radio FDAM-1 in 1964 and was assembled by Yoshitaka Iiboshi (call sign JA3LOQ) who still works for Icom….

Gladys Kathleen Parkin

 

At just fifteen years old, Gladys Kathleen Parkin (1901-1990) received her professional ham radio license. Basically, this makes her a total badass, considering that she’d had her amateur radio license since age nine. She was featured on the cover of The Electrical Experimenter, and at the time was the “youngest successful female applicant for a radio license ever examined by the Government at that time,” according to a 1916 article in the San Francisco Chronicle. Parkin began her hobby at age five with her brother, and was the first woman in California to pass the first-class radio license.

 

Parkin’s call sign is 6S0, and she spent her life in the radio industry, developing a reputation for building her own equipment. Here she is, quoted in The Electrical Experimenter:

 

With reference to my ideas about the wireless profession as a vocation or worthwhile hobby for women, I think wireless telegraphy is a most fascinating study, and one which could very easily be taken up by girls, as it is a great deal more interesting than the telephone and telegraph work, in which so many girls are now employed. I am only fifteen. … But the interest in wireless does not end in the knowledge of the code. You can gradually learn to make all your own instruments, as I have done with my ¼ kilowatt set. There is always more ahead of you, as wireless telegraphy is still in its infancy.

Glen Zook, K9STH, posted this to the Heathkit mailing list:

Many amateurs already know that “73” is from what is known as the “Phillips Code”, a series of numeric messages conceived for the purpose of cutting down transmission time on the old land telegraph systems when sending text that is basically the same.

In the April 1935 issue of QST on page 60 there is a short article on the origin of 73. This article was a summation of another article that appeared in the “December Bulletin from the Navy Department Office of the Chief of Naval Operations”. That would be December of 1934.

The quotation from the Navy is as follows: “It appears from a research of telegraph histories that in 1859 the telegraph people held a convention, and one of its features was a discussion as to the saving of ‘line time’. A committee was appointed to devise a code to reduce standard expressions to symbols or figures. This committee worked out a figure code, from figure 1 to 92. Most of these figure symbols became obsolescent, but a few remain to this date, such as 4, which means “Where shall I go ahead?’. Figure 9 means ‘wire’, the wire chief being on the wire and that everyone should close their keys. Symbol 13 means ‘I don’t understand’; 22 is ‘love and a kiss’; 30 means ‘good night’ or ‘the end’. The symbol most often used now is 73, which means ‘my compliments’ and 92 is for the word ‘deliver.’ The other figures in between the forgoing have fallen into almost complete disuse.”

One of the chief telegraphers of the Navy Department of Communications, a J. L. Bishop, quoted from memory the signals that were in effect in 1905:

1 Wait a minute
4 Where shall I start in message?
5 Have you anything for me?
9 Attention or clear the wire
13 I do not understand
22 Love and kisses
25 Busy on another circuit
30 Finished, the end-used mainly by press telegraphers
73 My compliments, or Best Regards
92 Deliver
Now days, 22 has become 88 (love and kisses). I don’t know when this came about. 30 is still used in the newspaper and magazine business to indicate the end of a feature, story, or column. And, of course, 73 is still used by amateur radio operators to mean “best regards”.

Making any of these numbers plural (73s, 88s, etc.) is incorrect since they are already plural. 73s would mean best regardses and 88s would mean love and kisseses. Those make no sense.

Anyway, the subject of where 73 came from comes up periodically and this article reinforces the “Phillips Code” origin.

Jim, N2EY, adds:

Some other related stuff:

Phillips Code “19” and “31” refer to train orders. They were so well known that the terms “19 order” and “31 order” were still in RR use in the 1970s, long after the telegraph was gone.

The abbreviation “es” for “and” derives from the Morse character “&”. The prosign “SK” with the letters run together derives from the Morse “30”.

The numeric code is a small part of the abbreviations outlined in the Phillips Code (developed by telegrapher Walter P. Phillips). Here are the numbers as referenced:

W I R E S I G N A L S
