|Codes were sung by users; see the voice typewriter employing Morse or votem||Speed in words per minute All Morse code elements depend on the dot length|
|Consequently, words also have different lengths in terms of dot duration, even when they contain the same number of characters||The fact that the transmitted power is concentrated into a very limited bandwidth makes it possible to use narrow receiver filters, which suppress or eliminate interference on nearby frequencies|
Non- scripts require more radical adaption.5
|This is granted either when the tests are passed or as the Second and First are renewed and become this lifetime license||[ ] As of 2015, the United States military taught Morse code as an 81 day self-paced course, having phased out more traditional classes|
|Warships, including those of the , have long used to exchange messages in Morse code||medium gap between words : seven time units long Transmission Morse code can be transmitted in a number of ways: originally as electrical pulses along a wire, but also as an audio tone, a radio signal with short and long tones, or as a mechanical, audible, or visual signal e|
This left only four codepoints identical to the original Morse code, namely E, H, K and N, and the latter two had their dahs extended to full length.
