[CW] Where did the SINE come from?

[D.J.J. Ring, Jr.]

Th e 'Sine'
Each telegrapher has his own "handle" or "sine", - his own identification,
usually his initials or a contraction of some form.

When one telegrapher inquires about another, he does not do so by name.
"What's his sine?" he will ask.

His sine's, RJ, CX, WX or whatever it may be, and he carries this sinie
throughout life, just as he does his name.

The "sine" came into use in the first days of telegraphy when it was
necessary adjunct to every cable message or wireless telegram message
transmitted and received.  The sine in the form of its two initials,
appeared on every message blank to identify the person who handled it.

And it was as foolproof as a fingerprint because no two telegraphers
adopted a similar sine.
