With all the antennas ganged up on the roof of such a small area they take each others radios out every time the other one transmits. Not if the comm center is properly designed. *The techniques for siting multiple transmitters/receivers in confined areas and minimizing mutual interference are pretty well established. If that is a real worry, each local amateur radio group can check it out for themselves...base-mobile-handheld, any combination they can operate on/in. There is really a great freedom in amateur radio to convene such a group for a real test at equipment distances on same or different bands using different RF output powers. That will yield data that can be of good use later in real emergencies. 73, Len AF6AY |

wrote: Has amateur radio actually helped handle problems caused by a disaster DURING an event or have they been relegated to emotional-support health-welfare messaging AFTER it? Personal listening experience here. There was a hurricane that went through South America a year or two back, on the way toward the US. I listened to an emergency net as a Ham was helping another who was on a small ship caught in the storm. I believe it was near Grenada. The ship was having engine problems, the skipper was inexperienced, and a ham with maritime experience was "procured" to talk the other guy through saving the boat and passengers. Listening to the transmissions, I have no doubt that had the instructions and help been relayed, the skipper and his passengers might have become statistics. Not being a mariner and one who avoids riding ON water, I can't comment on the veracity of that. :-) In a relatively recent event, a west coast sailor was attempting to sail solo towards the southern tip of South America, became damaged (de-masted?) and the Chilean Navy - Coast Guard came to his rescue along with other private ships in the area. The news of both search and rescue was carried on all the TV news and amateur radio did relay that news albeit a bit late. Was amateur radio communications "vital" in that case? Or wasn't it of a secondary nature in the form of "health and welfare?" I say the latter since the principal rescuer was the military of the government of Chile with the cooperation of fishing vessels in the area. Safety of Life at Sea has been a bond of ALL mariners since well before radio was demonstrated as a communications medium. This was a case of SOLAS in action. Those are two different conditions. Communications DURING an event have direct bearing on life-death situations while communications afterwards concern survivors, the living. The emergency is not a finite point. I have to disagree. Those directly involved in ANY emergency would probably agree with me on that. People who are injured during an emergency can survive or expire during the aftermath. Who can say which particular communications are critical except in retrospect? I would say the individuals directly involved can say that very definitely. Before this solo sailor's power ran out, he reported being de-masted and adrift and that his power was running low. To my mind that is about as direct a determination of an actual emergency as can be...albeit my not being a mariner. An airliner captatin reported an emergency when an air carrier's nose wheel did not retract properly; the nose wheel assembly had become turned from its natural position. The FAA accepted that as an emergency, coordinated with Los Angeles airports for emergency help, having fire engines standing by along with rescue workers. TV news relayed it live for viewers. Spectacular safe landing even though the nose wheel assembly caught fire. I don't recall the number of passengers on board but at least a hundred lives were directly at risk...all survived. Health and welfare comms are extremely important to those affected. It is important work, whether involved in dire emergency or the less pressing aftermath. Well, I was taking things in order of importance. When human life is at stake, I put the priority on direct emergency communications to save such life. Reporting on the results of aid/rescue afterwards after that would, in my mind, be deemed secondary. Yes, that secondary role is important for the emotional well- being of relatives and friends via "health and welfare" comms, but I still rank it secondary. Others may disagree. My question has always been, who is kidding who on all this "emergency work?" It's a serious question which always seem to raise the emotional hackles of some. There is a difference between Amateurs and those who are being paid for their work. The amateurs are not being paid. Yes, that is why the FCC titles Part 97 as "AMATEUR Radio Service." :-) Glad handing has sometimes been called the wages of volunteerism. Good point! But, my mention was in regards to amateur radio as a hobby, an avocation, something to be done in one's free time. Is/was the amateur radio service organized as an "emergency communications" primary role? Or was it organized as an unpaid, personal, technological-oriented activity done by individuals? I say the latter. Too often some individuals blend the two organization-origins with the "emergency" part rationalized as justifying the real activity. I would say that is wrong. As responsible citizens we all should help in some part with our communities in some way. Amateur radio is only one way to help and then primarily for rather extreme situations. I respectfully have to say that if a ham says something about Amateur radio contributions to emergency communications, there are some people who automatically dismiss their statements. Yes, there are. I've been called one of those! :-) Fortunately one does not have to engage in the activity as a ham. It is completely voluntary. True. The state of California Auxiliary Communications Service will accept anyone to help in emergency communications, licensed or not, as long as they can demonstrate they know something about communications. The California ACS considers ALL forms of communications to be vital and ANY that survive extreme emergencies would be used. Yes, having a license helps, whether commercial or amateur (in my case both), but that license by itself is not proof positive that an individual knows enough about radio and less about wired communications. Now, I've been accused of being geographically bigoted by mentioning California and the Greater Los Angeles area as models of emergency communications. For one thing, California is BIG having over 10 percent of this nation's population, rivaling the entire population of Canada. The state has weathered a tsunami wiping out a small coastal city, many earthquakes, many brush and timber firestorms, flooding, and damage from heavy rainstorms. The L.A. emergency communications center was new and operating for the 17 Jan 94 Northridge earthquake that affected about 10 million people and killed 53 humans...it worked through the efforts of organization, training, and regular drilling of participants. The "infrastructure" didn't fail and the cities making up this megalopolis survived. There's quite enough history of successful operations through very real emergencies available to anyone who bothers to look and seriously consider adopting those plans and experiences for their own communities. Examination of what has worked and what hasn't can be considered as a form of volunteerism... 73, Len AF6AY |

This doesnt' work with other radio services very well. Why would it be appropriate for Amateur Radio? Other radio services have distinct markets with distinct needs that they are chartered to serve. Amateur Radio is unique in that it is chartered as a playground for tinkerers and experimenters. It seems ironic to tightly regulate modes/bandwidths/modulation schemes in an environment where experimentation is officially encouraged. 73, de Hans, K0HB |

Amateur Radio is unique in that it is chartered as a playground for tinkerers and experimenters. * That's one of the reasons for amateur radio. But not the only one! A lot of different activities have to share the bands. But I like the playground analogy. All the playgrounds I've seen are carefully designed to support a variety of different activities. There are designated areas for various sports, for example. And there are rules to keep order, permitted and prohibited activities, etc. Certain activities need special permission, others are informal. IOW, there's a structure to a playground. And the structure is most important when the playground is small and the number of people who want to use it is large. There was a time when 99% of ham radio activity was either CW/Morse Code or plain AM voice. Back then, a simple structure was all that was needed. Those days are long gone. We need a lot more structure than before, IMHO. It seems ironic to tightly regulate modes/bandwidths/modulation schemes in an environment where experimentation is officially encouraged. Amateurs are much less regulated in that regard than any other radio service. IMHO 73 de Jim, N2EY |

Of course, I could probably take the FCC prose and ask Google to translate it; it would be just as opaque in the machine-translated version as it is in English/legalese. grin There's nothing wrong with the English version! Any communications attorney can understand it with no problem. big grin. When I was an advisor to the Israeli Ministry of Communications (40 years ago) one of my jobs was to rewrite and translate their amateur rules into English. No big deal - I'm technically fluent in both languages. Same for the Norwegian, or Swahili, or Urdu - get someone who is technically fluent in both languages and it's a snap. That job was a lot of fun, however. I fixed some problems that they didn't even know they had (and got reciprocity and third-party traffic approved in the process)! even bigger grin -- 73 de K2ASP - Phil Kane ARRL Volunteer Counsel email: k2asp [at] arrl [dot] net |

One of my favorite playgrounds is the Superstition Mountain Wilderness, a playground completely disorganized except for the boundary around it. You can go hiking there or ride your horse, prospect for gold (the "Lost Dutchman Mine" hasn't been found yet), camp for a night or a week or a month. You can follow trails which have been blazed by many hikers or horsemen before you, or be an explorer and leave the established trails to the timid. The only rules here are don't burn the place down, and don't trash the place for others. Explore without rules and structure. Kinda like I'd like to see the amateur bands, open for the explorers and visionaries (so long as they're polite to the other children). 73, de Hans, K0HB |

I think that the crux *is* just that politeness though, Hans. Almost any country you want to name, with the notable exception of the USA, hands their hams a set of frequencies and charges them to "play politely". I don't see any evidence that this policy is causing any problems. Even in our country, one mode is given free reign to use virtually any frequency they chose, and we all seem to get along. One has to wonder "if market-based cooperation works for one mode, why won't it work for the others?" 73, de Hans, K0HB |

What is the process of modifying the gentlemen's agreements? Specifically, I would like to explore the idea of adding a new PSK31 segment or two. It strikes me that we've beat this subject into oblivion without actually answering Mikes original question. Actually, the ARRL bandplans (for whatever weight they carry) are pretty much silent on the topic of PSK31. The mode settled by convention into a small spot on each band, and the original small number of players fit nicely into a fairly narrow slot by convention of usage. Since it's gained in popularity, I think the next logical step is for the users to start a discussion 'in-band' about annexing additional nearby territory. I'm not into that mode, but it's my impression that there's room in most of the data segments for you to spread out a bit without any particular resistance. In other words, let the 'market forces' come to bear. 73, de Hans, K0HB |
