TX and RX

Hello,

Out of curiosity, could someone provide me with a reference of where the acronyms
TX and RX come from? (not really acronyms I suppose, but these stand for transmit
and receive). Who started using these abbreviations and under what context? Are
these terms usable in general or only with reference to a particular protocol?

Thanks,

Neil

They're terms adopted from radio.

They've been in use for many years, with many types of equipment.

Indeed. I believe the X in TX is used to represent communication, though
I'm not totally sure. Anyway, the terms were first used in radio, probably
more as an abbreviation that anything else.

Actually, they are probably derived from early work with either
telegraphy or telephony, not radio. It is possible though, that
they began in radio and were transfered to telecom jargon in the
1920's and 1930's. I don't have the resources to be sure which
is it is.

The X is simply a replacement for all the letters that have been
deleted.

Transmit ==> Tx
Receive ==> Rx
Composite ==> Cx
Simplex ==> Sx
Distance ==> Dx

All of the above are telecom abbreviations that are also used
generally in radio communications jargon.

W[eather] ==> W[x]

Is another.

Those should not be confuse with the pattern used for OPX (Off
Premise eXtention) and FX (Foriegn eXtention) is not the same
use of the X.

Actually, they were also used in land line communications systems for years
as well, so it's hard to say where first used.

I've seen "xmit" being used as a short for (obviously) "transmit", and
I've had this idea since then that someone once thought "hmm, trans..
cross.. X!".

Going from this to "TX" and "RX" may be abit of a stretch tho..

And (we) the MIDI musicians also use TX and RX ...
