If you don’t know Morse code, you probably think of a radio operator using a “key” to send Morse code. These were — and still are — used. They are little more than a switch built to be comfortable in ...

Dot.” “Dash.” Short pulse, long pulse. Humans invented Morse code as a way to communicate using electrical signals. Now, bees ...

The wireless transmission is being demonstrated by the simple circuit which can send Morse Code signals over distances of a few meters to any AM radio. The Morse Code signal is considered as a ...

Thanks to Samuel F.B. Morse, communication changed rapidly, and has been changing ever faster since. He invented the electric telegraph in 1832. It took six more years for him to standardize a code ...

When the first radios and telegraph lines were put into service, essentially the only way to communicate was to use Morse code. The first transmitters had extremely inefficient designs by today’s ...
