I respectfully submit that most US hams don't have antennas like yours, Hans. Nor a similar location. My location is a suburban city lot on flat terrain in the acknowledge "black hole of propagation". My antennas are typical "Joe Tribander" --- one tribander, one "shorty-forty", usual collection of vertical alcoa and horizontal wire, no stacks, no long booms, modest height (55' telescoping tower with 15 foot mast extension, usually nested at about 40 feet). In a word, pretty average for a moderately active HF'er. It makes more sense than a free-for-all. "Free-for-all" is an emotionally charged term, calculated to engender visions of a street brawl. Maybe to you. Most of the worlds hams outside the US already enjoy the freedom to use the bands without government-mandated "segment by mode", and I notice no such brawls taking place. Doesn't mean they don't happen, just that you don't hear them. Is the USA like the rest of the world in terms of culture? Number of hams? Enforcement of regulations? By and large, hams seem to be a cooperative and responsible population with a good record of self-regulation. As a group, yes. But in certain specific instances (like 75 meters) things are not so rosy. I thought the proposal authors stated that concept quite accurately: "We believe the ideal band plan is one where good judgment on the operator's part supports use of any mode and any frequency available within their license class. Good judgment is centered on cooperative, flexible use of frequencies, with a specific goal of avoiding and/or resolving interference to others at a direct and low level, avoiding escalation and any need for outside enforcement. Sounds nice. Now tell it to those running robot pactor stations. Or K1MAN.. Guided by the use of good judgment, removal of artificial boundaries would encourage dynamic selection of frequency, affording an operator the best chance to minimize compatibility issues with other modes and activities. This would lead to greater band "loading" and improved utilization by allowing an operator to choose a clear spot on the dial across a greater frequency range. What amounts to "a clear spot on the dial" varies with mode. All I need for CW is a couple of hundred Hz. The folks running AM or hi-fi SSB need 10 to 20 times that much, and their receivers are (of necessity) much less selective. "Intentional interference with communications is a violation of the regulations, independent of the mode in use, and whether automatic, semi automatic, or manually keyed. Sanctions would continue to be available against deliberate interference or problems involving technical signal purity, using volunteer "official observer" type programs. If a documented problem remains chronic or unresolved, the intervention of federal authority would reinforce volunteer OO in self-regulation efforts, as it does today. Yeah, sure. How is the recipient of interference supposed to identify the source? "Automatic or semi automatic data operation not copied by the human ear becomes of particular concern under our proposal, since the activity would be unencumbered by subband. That alone makes it a bad idea. This group of users would have a specific challenge to maintain the good judgment pre-requisite by making certain their telemetry-polling systems recognize the presence of other modes and activities and avoiding interference to other communications. They can't even make that happen today. So we reward them by giving them the whole band to play in? Chronically failing to do so would remain an actionable violation under existing rules against deliberate interference, since it could be shown such judgment had not been exercised. *If* they can even be identified! "We contend that the goal of voluntary selection of operating frequencies for improved spectrum use is best achieved through real-time assessment of variables in propagation and radio traffic load. Efforts to improve spectrum use are currently constrained because these variables cannot be accommodated with fulltime, rigidly defined sub-bands. Sure they can, the authors of the proposal just don't want to. -- Let's get down to what this proposal is really all about: 1) More room for the 'phone folks/less for the CW & data folks 2) Less constraint on the robot-data-mode folks It's all gussied up with fancy, emotional verbiage like "real-time assessment of variables in propagation and radio traffic load" but the above two things are what it's really all about. What it also amounts to is *rewarding* the use of spectrally-inefficient modes. IOW, if the 'phone band is crowded, try CW, PSK31 or some other mode that doesn't need so much spectrum! "Additionally, contemporary technology offers interference protection at the receiver to an extent not possible 60 years ago, when protection was implemented by regulatory mandate to divide "phone" and "code" activity. Technology and patterns of use now encourage the more effective coordination that we propose." So we all need new rigs with all the bells and whistles. The separation of modes is a lot older than 60 years ago, too. It derives from a whole bunch of reasons. 73 de Jim, N2EY |

"Mike Coslo" wrote So does freebanding and pirate stations.. ;^) I'll ignore that remark, because I suspect you're an educated man who understands the difference between freedom and anarchy. Just a little zinger, Hans. 8^) The proposal (have your read it?) places great emphasis on responsibility and accountability, the handmaidens of freedom. Yup, I read it. I have mixed thoughts about it. I don't know that the present system is "broken", but I wouldn't mind having those robot stations all over the band instead of just the lower portions. Maybe they would be less likely to knock us PSK31 people off the air.. - Mike KB3EIA - |

The hams have VOLUNTARILY sorted out where to transmit. In other words, a regulation wasn't needed. What a concept! But would U.S. phone ops VOLUNTARILY stay up the bands and out of the segments historically inhabited by the CW and digital users if they were not restrained from doing so? Not in our lifetimes. 73, de Hans, K0HB w3rv Yes and no. 99.99% of us would stay within the IARU bandplan, but that includes large swathes of phone spectrum where we aren't allowed to go by the current FCC rules. Voluntary means we get to choose the bandplan, and= I would choose IARU Region 2, not ARRL. I plead ignorance of the IARU bandplans. Do you have a link to 'em?? Even without seeing them yet I like the concept.=20 w3rv |

The 160m band is becoming more popular with a.m. pirates. Sure, it is. Last time I was in Cincinatti... "Cincinnati" & Atlanta, I heard pirates in the 160m band broadcasting most of the night. They must be very, very weak pirates if you have to be near Cincinnati or Atlanta to hear them. I bet the hams in Cincinnati and Atlanta can take care of 'em in no time. Dave K8MN |
