For want of a band switch, you would let go of better (24hr) coverage? Maybe Jimmy the Riveter wouldn't mind stopping by with a chassis punch and wire up a new switch for you. It would be nice if all you had to do was put in a switch with more positions on it, but those darn "innards" would have to be modified too. Old equipment would probably have only a few bands it would operate on, and the olde analog dials would add to the problems. The old stuff would probably just have to be written off as a loss. Heaven forbid that a ham would modernize his station. Here's an idea. Just keep on using them as they are, on the bands they are on. Newer equipment would be more amenable to modification, and displays would more likely continue to work. Of course, someone has to do the mods, or the new equipment gets consigned to the recycle bin too. Some of the newer equipment would possibly not be convertible People who have MARS licenses do it every day. I wonder if Steve ever held a position of "authority" in MARS? Okay, so lets say we just ditched all the analog equipment, and most all of the digital equipment up to date of change. Knock yourself out. Now lets talk about antennas. It isn't likely that we will have single antennas at any station, save for the resurrection of the old general purpose dipole fed with ladder line, run through a tuner. That's one that olde tyme hammes will recognize! I suppose the Steppir antennas could work if you have enough coin. The method proposed by Jim will not accommodate the tricks we use now to provide an acceptable match as the major HF bands will not be harmonically related. Trap dipoles don't have to be on bands that are harmonically related. Perhaps we should go back to what Jim posted with his original question: Jim's quote * Right now we have 9 HF/MF bands, plus some spot frequencies in * the "60 meter" region. * * Suppose that at some point we hams had the choice of either: * * 1) New, very narrow bands elsewhere in the HF/MF spectrum (say, 2.5 to * 2.6 MHz, 6.0 to 6.1 MHz, etc.. * * or * * 2) Widening of existing bands and/or change to worldwide amateur. Such * as 7.0-7.4 becomes worldwide exclusive amateur, 10.1 to 10.2 does the * same, 14.0 to 14.4 (which the band used to be), etc. * * Which would be preferable, if we wound up with the same number of kHz * overall? End Jim's quote. Under Jim's scenario, we would be adding several bands. That trap dipole would be interesting indeed! Likely mostly traps. Maybe I'll try to design one. Jim will have to give me the specific frequencies that will be added in his scenario. And trsp dipoles are not a very universal answer. In my situation I would have to make a loaded trapped dipole for 80 meters and to cover other bands. Now *that* would be a hoot! And quite heavy. All in all, no thanks. - Mike KB3EIA - Congrats. You've just made "Full" member. Full member of what? I've given my opinion, and it is based on some technical and practical reasons. Your reason is that my opinion makes me a full member of something because I gave an answer based on those reasons. If you want to say I'm wrong, then fine. I don't care about being proven wrong. Show me *why* my opinion is wrong. If I can't refute it, I'll admit it and I'll learn something from you. But otherwise you're just castigating me for the sake of doing it. - Mike KB3EIA - |

Trap dipoles don't have to be on bands that are harmonically related. Not if the passband you want to operate on falls within the other desired band. In most cases you still need a tuner for bands other than the ones the antenna is cut for. You noticed that too? I'm waiting for the specific frequencies Jim is thinking about, so I can design a multiband antenna for this idea. I suspect I'll not be too successful. Maybe some others might have more success. Hopefully they will share their design with me. - Mike KB3EIA - |

I've given my opinion, and it is based on some technical and practical reasons. Your reason is that my opinion makes me a full member of something because I gave an answer based on those reasons. Sorry that Jim's idea presented too many problems to be overcome. Relax, it's not likely to happen. You're off the hook for needing a light weight multi-multi-band antenna. If you want to say I'm wrong, then fine. I don't care about being proven wrong. Show me *why* my opinion is wrong. If I can't refute it, I'll admit it and I'll learn something from you. Emergency communications requires propagation. The more band segments that you have, no matter that they are narrower, the more likely that you will be able to communicate. Passing on more bands for want of a band switch or a light weight antenna doesn't appear, at least to me, to be in the best interest of amateur radio. But otherwise you're just castigating me for the sake of doing it. - Mike KB3EIA - Status Quo Forever! |

The method proposed by Jim will not accommodate the tricks we use now to provide an acceptable match as the major HF bands will not be harmonically related. ??? There are solutions to both the rig and antenna problems. But they aren't as easy as some would have us believe. More important, unless a considerable number of hams equip themselves to use the new bands, they aren't much help. And does propagation varies that much between most of the bands we have now? I don't think so. It was argued that the difference in propagation between 80 and 40 could be great enough that access to a band near 60 was needed. And we almost got a full band there, except that NTIA reversed its support after 9/11. But the jump from 80 to 40 is a doubling of frequency. From 40 to 20 is a doubling also, but we have 30 meters in between. Would a band at, say, 8.5 MHz be that much different from 7 and 10 MHz? Or would we be better off with more worldwide-exclusive-amateur-kHz on 40 and 30? Trap dipoles don't have to be on bands that are harmonically related. I've built and used trap dipoles. The more bands you add, the more complex the adjustment procedure becomes. Does anyone else here have experience building trap dipoles from scratch? Perhaps we should go back to what Jim posted with his original question: Jim's quote * Right now we have 9 HF/MF bands, plus some spot frequencies in * the "60 meter" region. * * Suppose that at some point we hams had the choice of either: * * 1) New, very narrow bands elsewhere in the HF/MF spectrum (say, 2.5 to * 2.6 MHz, 6.0 to 6.1 MHz, etc.. * * or * * 2) Widening of existing bands and/or change to worldwide amateur.

End Jim's quote. Under Jim's scenario, we would be adding several bands. Under one of my scenarios, anyway. That trap dipole would be interesting indeed! Likely mostly traps. Maybe I'll try to design one. Jim will have to give me the specific frequencies that will be added in his scenario. Let's say the following additions/changes were made: A new band 50 kHz wide at 2.7 MHz A new band 50 kHz wide at 8.6 MHz A new band 50 kHz wide at 11.9 MHz A new band 50 kHz wide at 16.0 MHz A new band 50 kHz wide at 19.6 MHz A new band 50 kHz wide at 23.2 MHz A new band 50 kHz wide at 26.4 MHz or 5.1 to 5.2 MHz instead of 5 channels 7.0 to 7.3 worldwide exclusive amatuer 10.1 to 10.2 worldwide exclusive amateur 18.05 to 18.2 worldwide exclusive amateur And trsp dipoles are not a very universal answer. In my situation I would have to make a loaded trapped dipole for 80 meters and to cover other bands. Now *that* would be a hoot! And quite heavy. Some folks can't even get a random wire up and radiating HF RF.... 73 de Jim, N2EY |

Might as well be all black or all white because at the end of the day there are still people who support the wall. All purposeful action starts with an idea - a dream, as it were. First the idea, then the actions to make the idea become a reality. Sort of like showing one's REAL patriotism by volunteering for milirary service? Let's see if we have your thinking down, Leonard. Someone who doesn't volunteer for military service, especially in time of peace, isn't a patriot? Is that what you're saying? The person who will not allow him/herself to believe they can do something is already defeated. tries to sound like a Reverend on morse code, preaching from some ivy-covered pulpit. [pulpit fiction but without a Travolta] Is this a prelude to (roll drums) ...A Sermon On The Antenna Mount? Can become an artist-illustrator, traveling from place to place, painting portraits? Sam Morse did that. Sam and his financial backer Al Vail invented morse code. ART with minor success at it in any media REQUIRES a built-in aptitutde for that (or an excellent PR/gallery person to sell "great art"). Aptitutde, dutde? I started out WORKING as an artist-illustrator because I did have the built-in talent/aptitude for that. Not only that, my completed works were BETTER in any media than Sam Morse's. If you DO say so yourself... That Test Element 1 remains IN the amateur radio regulations is due primarily to the incredible acrimony of those olde-tyme hammes who cannot bear to lose the one link to their personal "fame" that set them "up above their fellows" (as hobbyists). You have incredible acrimony over the issue of morse testing, yet the test remains. Go figure. Dave K8MN |
