^ With BPL coming Morse Code might be the only way left to ^ communicate on HF. So you think CW will come through the interference fairly well? I guess everything will if the range is close enough, like within a few blocks perhaps. You're probably already aware of it but ARRL conducted some field experiments in areas where the power companies are testing BPL. I didn't read the report but I recall hearing that the interference was about S9 in those areas. Frank |

So am I still correct that the advantages of CW a - Narrower bandwidth. The bandwidth is effectively even narrower because overlapping adjacent signals can still be distinguished by the human ear. - Greater effective range. - Less equipment than other data types, which also have greater bandwidth. - Can be used without a microphone and without a key. Just open the box and short a couple of contacts. You forgot one: Imminent extinction. |

Now that was about a lame argument.

Sorry I'm not a ham and I don't want to see CW go. It call BASICS! Once you start forgetting about the basics then you start developing a backwards nation. Just look at school, they don't teach the basics any more they just throw the kids on computers. Do you know a single McDonalds employee who can make change in their head??? CW isn't hard to learn, not even a ham and I can receive 15 WPM and actually enjoy it.... George http://www.MilAirComms.com |

What is the USA waiting for?? Will we be the only country in the world
with a morse code requirement?? Ireland and Singapore have become the latest countries to remove the requirement for Amateur Radio applicants to pass a Morse code examination for HF access. In addition, Switzerland, Belgium, the UK, Germany, Norway, the Netherlands, Austria, New Zealand and Australia have moved to drop their Morse requirements. Yet the USA will surely be the last to join the rest of the world in doing what is obvious to everyone else. |

If all these countires jumped off bridges would that mean we would be nuts for not jump too? What these counties do are their own business and who wants to be put in the same class as Germany anyway! Yet the USA will surely be the last to join the rest of the world in doing what is obvious to everyone else. Oh I hope not, I hope the USA never joins the rest of the world. We don't need a 80, 40, 20, and 15 meter CB bands. God forbid that we have something happen here far worse than 9/11 which renders Voice communications useless and we need to go back to basices. After all its a lot easier to build a CW rig than a voice rig in the event of a national emergency. Once you stop teaching/learning the basics then you'll gradully become a less educated national. Just look at workers in McDonalds, when the computer quits working they can't make sales..... George http://www.MilAirComms.com |

Like terrorists stab everyone who has a radio transmitter in the throat with a pen, or even worse? Perhaps a laryngitis epidemic? After all its a lot easier to build a CW rig than a voice rig in the event of a national emergency. That is why I have a 50,000 volt spark gap rig in storage. LOL Once you stop teaching/learning the basics then you'll gradully become a less educated national. Just look at workers in McDonalds, when the computer quits working they can't make sales..... Well, considering McDonalds isn't set up for paper & pen transactions I would say that is understandable. How does your ebay business do when your computer takes a ****? |

Spurious Noise yI5eb.34774$Ms2.224@fed1read03... ^ Just FYI: ^ CW Bandwidth = wpm X 4 (e.g., 40 WPM = 160 Hz) ^ From the ARRL License Manual 1976: ^ "With proper shaping, the necessary keying bandwidth is equal to 4 ^ times the speed in words per minute for International Morse Code; ^ e.g. at 25 words per minute, the bandwidth is approximately 100 ^ cycles." Thank you. SSB is about twice that right? And isn't SSB the narrowest voice emission? Frank An SSB signal is about 3000 cycles/sec (i.e. Hertz) or 30 times as wide. AM and FM are even wider. Dee D.

Just open the box and short a couple of contacts. Frank Pretty close. Some of the other digital modes are narrower but as you state, you need more hardware such as a computer. In addition each of the other digital modes has its own unique set of advantages and disadvantages in on air operation. Dee D. Flint, N8UZE |
