"J. D. B." wrote in message ... Al, someone who passes a code test should be more proficient in code than someone who cannot pass the code test. That simply makes that person proficient in code, not necessarily a more proficient operator. If they are proficient in code as well as other modes, then they are a more proficient operator. The more you can do, the more proficient you are. You may be able to use the code, but if you cannot use modern digital methods, use sat communication, able to handle emergency communication, able to set up digital networks and use them effectively, build modern solid-state equipment, etc., then you are not a more proficient amateur operator, you just are more proficient in code and that is not going to help us much in the 21st Century. Setting up digital networks may not be particularly practical in the early days right after a large scale disaster. Satellite passes are short and if you don't have internet access to look up pass times, you may be up the proverbial creek without the proverbial paddle if you rely too much on that form of communications. Even with the pass info, the passes are too short to be useful for handling very much emergency communication. As I said before, PSK31 can be copied when the human ear cannot even hear the signal, if you cannot hear code, you cannot copy it period. So code is no longer the be-all-end-all. Modern 21st communication methods have replaced it. Yes it is true that PSK31 can be copied when you cannot hear it. However, it is useless when there are ionospheric disturbances that cause phase shifts (solar flares with the attendent aurora come to mind). This happens on a fairly regular basis. In addition, although the signal you are putting out is low power, PSK31 has a fairly high power consumption requirement since a computer is essential in the system. If you have limited power resources, it may not be a wise choice. While code is not the end-all and be-all, it still has its place in list of communications methods. Let us go back to the auroral activity. The various digital modes fail first. Voice holds up a little bit longer getting distorted but sometimes still copyable. Code holds up a bit longer, being still copyable when voice becomes too distorted. Under auroral conditions, both voice and code fare better than digital. Every single method has a valid place in the list of communications methods. Every mode has its strong points and its weak points. In my opinion, hams should be able to use as many modes as possible and that includes code. The major drawback to code is that it requires people to develop a skill rather than being a matter of just slapping parts together. Heck, I don't any skill in soldering as I've soldered only about 4 items in my life but I built both myself and my OM PSK31 interfaces in about 1/2 hour each. They were two of those four items. If we are going to attract new people to the service, we need to get into the 21st Century and get the old farts away from the old code and tubes crap. I find that it is the "old farts" who are doing most of the exotic activities. When I work PSK31, I come across many seniors working this mode with the latest radios and computers. When I work VHF/UHF contests and look up the call signs afterwards, it is mostly the experience hams that I run across. You have let your disdain for the code blind you to its merits. As I stated above, EVERY mode has its strengths and weaknesses and its place in wireless communications. Dee, N8UZE |

Dee, the issue is that many old hams know CW, but cannot operate most
new digital modes. But if I understand what you are saying, if a 20 WPM Extra Class ham only operates CW and maybe SSB is less proficient than a 5 WPM Technician that operates on 10 different digital modes. See the 10 modes is more than CW and SSB, that ham is more proficient. Then I guess I agree with you. Your comments on setting up networks, sat communication, and digital modes show that you have little knowledge on either. For instance, it depends on the sat orbit how long it is useful. If PSK cannot be used due to ionospheric disturbances, well then either can CW. Computers can be operated on battery or generator. You are going to need something to power the radio right? Does not take much more for a laptop and with digital modes, the power can be much less so there is more power for the laptop. Your comparison of voice, digital modes and CW shows you have little knowledge of what you are talking about. I have personally used digital modes when voice and CW were not able to be copied. Finally, I happen to like CW a lot. But I don't think it makes anyone a better operator for knowing it, you should not be tested on it anymore than any other mode. Yes, there are a lot of seniors using digital, but there are too many more hanging on to the old crap CW only and tubes.

And many of us know CW, originated some digital modes (you think teen-agers invented everything?) and can certainly operate most, if not all, of them. We had working RTTY (that's digital) regenerating repeaters (thanks, Norm) before most current hams were even born. If PSK cannot be used due to ionospheric disturbances, well then either can CW. Not true - the human brain is a more efficient detector than a computer sound card in some cases. Computers can be operated on battery or generator. You are going to need something to power the radio right? Does not take much more for a laptop and with digital modes, the power can be much less so there is more power for the laptop. You can get a CW signal to anywhere in the world with a 9 volt battery for a few hours. You can't run a pocket PC on that kind of power. Your comparison of voice, digital modes and CW shows you have little knowledge of what you are talking about. I have personally used digital modes when voice and CW were not able to be copied. And I have personally used CW when digital modes weren't even detectable, let alone copyable. So have many people who have used CW for extremely low signal work. Try decoding a PSK signal that's been bounced off an aurora. (The phase is constantly rolling - there's nothing for the detector to detect.) Aurora CW sounds weird (okay, it makes "weird" boring), but it's easy to copy. Finally, I happen to like CW a lot. But I don't think it makes anyone a better operator for knowing it, you should not be tested on it anymore than any other mode. Okay - the same then. You're tested on your ability to understand English, and to read the written word - that covers voice and digital. Let's test for CW. Not "more", just "same". Yes, there are a lot of seniors using digital, but there are too many more hanging on to the old crap CW only and tubes. And too many youngsters who think that it it's old it's automatically crap. |

Under auroral conditions, both voice and code fare better than digital. Thanks for the memories. I enjoyed "the barrel" in the late '50s. No one who works voice on aurora will ever forget what it sounds like. Or forget working half-way across the country with 5 watts on 6 with a TV antenna. The major drawback to code is that it requires people to develop a skill rather than being a matter of just slapping parts together. The problem is that a lot of people think that all the "skill" operating takes is being able to turn the equipment on. Even using an appliance rig, it's easy to tell the appliance operators from those who have developed some skill. If we are going to attract new people to the service, we need to get into the 21st Century and get the old farts away from the old code and tubes crap. I find that it is the "old farts" who are doing most of the exotic activities. When I work PSK31, I come across many seniors working this mode with the latest radios and computers. I'll second that - from the old fart side. ![]() Al - W2PMX |
