A person uses a telegraph to send Morse code messages by pressing a transmission key. Pressing the key briefly sends a dot and pressing the key longer sends a dash. A device called a register receives incoming messages and transcribes them by marking dots and dashes on a strip of paper.

How much did it cost to build a telegraph?

Samuel Morse, for example, went to the US Congress in 1843 when he was seeking funds to demonstrate his telegraph system by running a telegraph line between Washington and Baltimore. The line was completed in 1844 at a cost of $30,000.

What sound does a telegraph machine make?

When a telegraph message comes in it produces an audible “clicking” sound representing the short and long keypresses – “dots” and “dashes” – which are used to represent text characters in Morse code.

Is Morse code still used?

Today, American Morse code is nearly extinct. A few amateur radio users and Civil War re-enactors still keep it alive. Pilots were required to know how to communicate using Morse code up until the 1990s. Today Morse code is primarily used among amateur radio users.

What did a telegraph sound like?

As long as the telegraph key was pressed, the transmitter would produce a string of transient pulses of radio waves which repeated at an audio rate, usually between 50 and several thousand hertz. In a receiver’s earphone, this sounded like a musical tone, rasp or buzz.
