Morse code might seem obsolete but for situations with extremely limited bandwidth it’s often still the best communications option available. The code requires a fair amount of training to use ...

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 ...

Long before pixels and cell towers, there were dots and dashes. Morse Code was the complicated mainstay communication of choice practically from the day Samuel Morse started clicking his prized ...

The Maritime Radio Historical Society , working with the Marconi Conference Center, will return Morse code radio station KPH to the air from its original Marin County, Calif., location on Feb. 26. KPH ...

A portable practice set in a case used for teaching telegraph and wireless operators Morse code. Spring-operated motor with winding crank on right side. A punched-paper tape is pulled around a spindle ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...
