摩尔斯电码(又译为摩斯密码,Morse code)是一种时通时断的信号代码,通过不同的排列顺序来表达不同的英文字母、数字和标点符号。它由美国人艾尔菲德·维尔于1837年发明。 摩尔斯电码是一种早期的数字化通信形式,但是它不同于现代只使用零和一两种状态的二进制代码,它的代码包括五种: 点、划、点和划之间的停顿、...
Morse code, a FM radio receiver which receives the Morse code signal from the distant transmitter, said Morse code signal is attenuated to required level before connecting to Band Pass Filter to pass the Morse code signal, and a phase lock loop circuit receives the Morse code signal from BPF...

This key was often used with the T1154 transmitter and R1155 receiver combination. Thus the key was widely sued for radio communications and it is likely that this form of key as used to send the messages back from raids such as the famous "Dambusters" raid over Nazi Germany.Read...
Adaptive Design's Morse Code for GBoard Hardware Interface Pack PRODUCT ID: 3937 At the time of its invention Morse code definitively changed the way we communicate. Historically it's been used in nautical navigation to aviation to radio, but its easy to learn and the universal nature makes it...
Oh, yes, there was the matter of S in RST, the signal strength factor. If you had sufficient power and a good antenna you could work the world on CW, even if the guy on the other end used a one-tube regenerative receiver and a pizmire transmitter. On the other hand, if your fist...

From a modern perspective Morse code has a number of drawbacks including a data rate much slower than voice or modern digital methods, but over long distances, in adverse conditions or with little transmitter power available, it has been the preferred mode for reliable point-to-point communication...
