a really electronics dummy question

[learner]

what does the X stand for when you guys talking about TX & RX ?

T = Transmit
R = receiver

X = ?

happy Xmas

I think the x in tx and rx has the same function like
Xmas = christmas

Hi,
It's old story about early years of telegraph and radio communications:
the X stay for an abbreviation used in telegraphic and radiotelegraphic communications...

so in that abbreviations TX stay for transmit, transmitter (station), transmission and the like and RX stay for receive, receiver (station), reception etc

Now why ? Easy, in old times where people need using e.g. Morse code it was very common adopting that short acronyms...or shorthands ...you need only 2 characters instead of many and still today these are in use as telegraphic shortends ...along with others like DX (distance/distant communication) etc

So, it's not something related to MDs... but to electronics and communications in general.

Kind regards,
Max

hi

I think that X stand because we transmit and receive a wide band of frequencies.

So we put X (like unknown variable in math)

Hi,
Yes, the definition from Max is right to me.

That's interesting ... I didn't know the reason.
Never really thought about it.
Not such a dumb question after all.

Yes MAX you are correct .. we call them pro-words and there are many of them also we use Q codes and Z codes ... it makes it easier to send our CW.
e.g.
TKS FB 73'S IMI QSL
