But once the last license goes to SK what's to stop the FCC from giving it all away? Well, one of the nice things about code is that you don't _need_ very much bandwidth. And with modern DSP you should be able to make IF filters even narrower than my old R-390... should be possible to cram hundreds of carriers into the space of one SSB channel. So true, and low bandwidth helps CW get though when SSB would be impossible. However, don't forget that CW can be done quite nicely with a cheap computer, some simple cables and some free software without learning it. I suppose that one could argue that a human ear can hear what a computer can't, but I'd be willing to argue that point in favor of the computer. Actually, you would lose such an argument. There are many hams who have proven that they can decipher better than the computer. The computer hardware or software requires the following characteristics in the received transmission to work: 1. A strong signal 2. No distortion on the signal such as occurs from aurora, meteor scatter, etc. 3. The code sent is nearly equal in quality to that sent by a computer. Some one using paddles may achieve that but if they are sending with a manual key or bug, that is highly unlikely. I have frequently been able to copy better than the computer and my code skills are quite modest. The only time it beats me is when the code meets the above three criteria and is too fast for me to copy. I'll be willing to bet that there won't be much improvement over CW in the raw "get the message though under bad conditions" power with the new digital modes using the same bandwidth as CW. Simple is under-rated in my book. I'm not sure I understand what you are saying here. Did you leave something out? As an operating mode CW is alive and well and likely to stay, however it will be computer driven more and more as the art dies off and new blood is not required to learn it as well as the old. Change is neither good or bad, it's just change. While change is neither good or bad, sometimes the results of change can be undesireable. Dee, N8UZE |
