Ultimately, we need to treat these various modes as methods of sending text - no more and no less. I disagree! Morse Code is more than simply a method of sending text. Two methods that send the same text are competing modes, regardless of whether keyboards, a telephone keypad or a telegraph key is used to send it. I disagree again! Lots of differences, for example, a simple telegraph key can be made in a few minutes with simple tools. Keyboards are a bit more work. A method that sends those blocks of text faster and with fewer errors is better. A slower, more error prone method is inferior. If the only factors considered are speed and accuracy, that's true. But there are other factors when it comes to things like amateur radio - bandwidth, required equipment, etc. Not all encoding schemes are equal. Some, like ASCII, encode the entire alphabet, including upper and lower case. Others, like ISO-Latin-1, can encode even more characters. In general, the more inclusive encoding method is better. An encoding scheme that is easily adapted to error correction (parity, automatic re-send, etc.) is also considered better. See above about what factors are considered. So claiming that phones, data modes and Morse can't be compared because they are somehow "different" ignores the ultimate reason for their existence - text communication via radio. One can compare all sorts of things, and have the results come out differently depending on the factors considered. Is rollerblading "better" than running because the same person can go faster and farther for the same effort? The real point of the Jay Leno clip was to show that the assumption of "newer is faster/better" turned out to be exactly wrong. The audience and the woman Leno talked to were *sure* the text-messager would win, yet Morse Code was faster. If all you want to do is send text from point A to point B, there are lots of good modes. But consider these factors: 1) Morse Code can be manually encoded and decoded by humans and machines. RTTY, ASCII, etc., cannot, at least in practical terms. (Yes, I once got to the point where I could usually recognize "RYRYRY" and "W3ABT" in 45.45 baud Baudot FSK, but have you ever met anyone who could have conversations that way?) 2) Morse Code can be done with audio or video - by watching a flashing light, text on a screen, or simply listening to it. Audio reception is a big advantage in situations where a visual display isn't practical. 3) Morse Code can be implemented with a bare minimum of simple equipment, or with complex equipment, or anything in between. There are lots more, that's just a sample. None of this proves the idea that all radio amateurs must use Morse Code, or must pass some sort of test on it, etc. That issue has been decided (at least in the USA). --- Should radio amateurs not *use* Morse Code any more? 73 de Jim, N2EY |
