code speed การใช้

• There is also a Morse Code speed certificate.
• An additional advantage of electronic keyers over semiautomatic keys is that code speed may be easily regulated and changed with electronic keyers, typically by turning a knob.
• At 20 word per minute code speed this means that "'QSK T / R switching times must be in the range of 1 to 1 / 2 millisecond "'or below.
