How does old Morse Code work and transmitted?

Answer 1

The "morse code" is a method of representing letters by combinations of short, or long, signals.... "dots" and "dashes"

The most famous example is probably the universally known "SOS"... in Morse Code, it's dot, dot, dot (S), dash, dash, dash (O) dot, dot, dot (S). Very easy to pick out of background noise.... dididitdaaadaaadaaadididit... A sequnce burned into the synapses of any marine radio operator

It was originally developed for use on the Morse Telegraph (Morse was the man who invented it), in which pulses of electrical current were sent down the wire.
The sending operator pressed a key, to allow the current to flow.. a long press for a "dash", a short press for a "dot" . At the other end, the current energised an electromagnet, which operated a "clicker". The receiving operator would listen to the clicks, and transcribe them back into letters of the alphabet.

Later, of course, it was sent as a series of short and long tones, by radio, where it could be heard much better than voice signals, in poor radio conditions. It can also be sent as a series of flashes from a lamp... which has the advantage that it can't be overheard...

There's a fairly common cellphone ringtone, used to announce the arrival of a text message... correctly known as Short Message Service... So the tone plays, in Morse, "SMS". Now, M is dash, dash... as opposed to the dash, dash, dash of O... so it's very, very close to the signal for SOS... "dididitdaaadaaadididit", as compared to "dididitdaaadaaadaaadididit" and every time somebody's phone does it, I find myself reaching for a notepad and a map... (ex sailor..:-)

Answer 2

Hi. Morse code (called CW by radio operators) can be transmitted over radio, over wires, through a pipe, or by writing down the dots and dashs (called dit and dahs). Your avitars initials are "dadadit dadidadit"

Answer 3

It would work with magnets and electrical charge.

If you wanted to send a dash you would send two quick electrical charges down a line, this would turn on the magnets on the other end and a person would hear the dash.
