Well, Leonard the devastation of New Orleans reveals near total collapse of the commercial communications infrastructure. Hams are there and are producing. The Feds are rushing communications equipment into place but amateur radio volunteers are already on the job: and indeed the article in the washington post ( http://www.washingtonpost.com/wp-dyn...083102656.html ) prove Len correct text messaging system are there plugging allong with the hams remainder cut to save BW |

The point is that you can't find a ham. CB radio covers local comm, and LOCAL comm comprises the VAST MAJORITY of emergency communication. Which more than likely it won't be via cb, but ham radio UHF/VHF or other services on UHF/VHF. There simply aren't enough hams to cover all the emergency comm they claim to be able to cover. They might have the ability to play some emergency-DX but they simply don't have the numbers. And 10,000 idiot cbers all shouting "ten fer thar", and "aaaaaauuuuuudddddiiiiiooo" all over 11 meters is a large number of idiots with radios, but of no help at all. The idiots are the hams manning their keys while people drown in their own homes. At least they are helping in a way they are capable. So you want them to paddle out on their radios to save someone? And what are you doing while people drown? Anything? Didn't think so. |

However the intermediate distances of a few hundred miles just are not going to be covered unless you are lucky enough to get some uncommon propagation modes like backscatter. What makes you think that DX radio comprises all -- or even a major part of -- communications in a disaster or emergency situation? No one has said that is does frankie, do please try to keep up. |

) prove Len correct text messaging system are there plugging allong with the hams You seem to indicate that text messages can magically access the system when voice cannot. If you can't access the network for voice you can't access it for text messages either. The only reason they are using text messaging, where they can get a signal which is very spotty, is because text is sent in small packets thus saving batteries and ties up the network less. "Mobile-phone providers said their service was *severely limited*, at best, in New Orleans and along the Mississippi coast, and they encouraged people to use text messages instead of making voice calls. Text messages are sent in small "packets" of data, using less bandwidth to get through overloaded lines more easily." If the cell network is down, so is text messaging. |

From: Jim Hampton on Aug 31, 5:08 pm wrote in message Doesn't matter about MODE...all good morsepersons know that all amateur radio SURVIVES all possible emergencies, floats on water while the hams walk on water...:-) Of course not Len. Not everything survives; the portable and mobile stuff will survive far better than the cellphone towers, police towers and even amateur towers. The smaller towers (usually amateur), however, do have the one advantage of a much smaller windload to carry. Really? :-) Maybe you're right. Amateur radio towers are kept up by FAITH. Busy gal that Faith... Hmmm...looking at the terrible scenes in Louisiana and Mississippi, I couldn't help but notice a few police officers about (in New Orleans) with one talking on his police HT. Then, on NBC news with Brian Williams, a video clip showed an antenna- laden Humvee of the Mississippi National Guard. Oh, and the USCG with all those helos and the hoister guy talking with the loader-into-the-basket guy on some kind of radio. Presumably the helo pilots can talk to their base of ops by radio. Oh, and all the news commentators in shirt-sleeves doing their video-audio reporting from on-scene...and various folks telephoning in audio stories. Yup...the whole INFRASTRUCTURE went totally kaput at the end of the Mississippi River! The biggest difference might just lie in understanding how things work. ESPECIALLY everyone's local INFRASTRUCTURE, communications-wise. I've been involved in exactly two emergency situations. One was on ssb with Hans K0HB and the other was on 500 KHz. Yes, the cw is old, but the situation involving Hans can happen at any time. Amazingly, that huge coast guard tower did *not* survive the typhoon. An hf amateur rig could load a chain link fence and provide reliable communications. So, do tell us your experiences with emergency communications and why you know that amateur radio will always (or never) float. 1994 Northridge Earthquake. TOTAL loss of electrical power to about 10 MILLION a few minutes after 4:30 AM. [53 persons died as a direct result of that quake] Some places had severe structural damage, gas main in Northridge ruptured, caught fire, various utility poles and their lines down in many places, a few collapsed freeway overpasses. LAFD and other professional FDs had leased lines that went straight to stations, didn't go through the switching centers of telephone offices. All of them followed the pre-existing emergency plan and rolled out. A few answered radio calls to fires that had broken out (FDs have back-up electrical power for their base stations). PDs were in constant contact by radio, their bases also having backup electrical power. The hospitals of course had their emergency electrical generators going and most of the ambulance services not a part of hospitals were able to communicate by their radios. TOTAL street blackout except for headlights of vehicles, that way until sun-up (late, it was January 17th). Utility companies had the greatest workload of all, but they had their radios and could communicate...just too many places to go to to fix things all at once...but they managed to contact all able employees to get them to work (some going direct to repair sites). Electrical power restoration didn't come back until shortly before noon, a sequential area-by-area turn-on necessary to keep the AC frequency constant. Got my residence power back at 2 PM, could see the TV scenes (TV broadcasters long ago had backup electric power). FEMA was on the scene the next day, doing the first real trial of their flyaway terminals...and set up VIDEO bulletin boards so that folks here could post things for faraway family and friends. About 2:30 PM on the 17th I got a telephone call from my uncle and aunt in Florida, worried call; we were okay and we talked at some length. They had no problem getting through. I got a call about 10 AM (give or take) wanting me to help out with a utility company the next day; no problem getting through to my residence phone. Was there any amateur radio activated here on that 17th of January? I'm not sure. Haven't heard of any locally. All I know is what I've seen of the Greater L.A. Emergency Communications System and its periodic drilling, refining of procedures, etc. Amateurs were not a part of that in 1994. That system worked just as it was expected to, even if it was part of the INFRASTRUCTURE that "was supposed to fail." Ham equipment can "float?" Haven't seen any yet with floation devices. I'm sure someone can jury rig something for them. National HROs and Halliscratchers are all boat anchors and will dutifully go to the bottom of the water. Larry Roll once postulated a Ten-Tec that "floated ashore" to a hypothetical desert island after a hypothetical ship sinking and he used that to send hypothetical messages from that by hypothetical morse code (which didn't require any hypothetical electric power..."CW gets through when nothing else will" and stuff like thet there). Larry had too many hypos perhaps and departed the newsgroup on April 15 last year. My house is 830 feet above mean sea level; am NOT worried about flooding. Now, I'm absolutely sure that amateur radio CAN be a definite help in a big disasterous emergency. Sometime. Besides the documentary film about invading space aliens, that is. I'm just NOT convinced that the INFRASTRUCTURE is going to FAIL to such as extent that amateur radio is "the only possible savior." From what I've seen on the TV news of the terrible destruction from hurricane Katrina, the average amateur radio station in the average New Orleans residence is not only submerged to the roof line, but the electric power to it is out and any emergency generators that might have been at those stations are completely under water. If the shingles of a roof can blow off completely in the downwash of a USCG helo (as has been seen by millions of viewers), you'll have a hard sell to me on saying "amateur radio towers have less wind loading and will survive" because I ain't gonna believe some rinky-dink wire antennas I've seen can hold up under 100+ MPH winds. I WILL believe an NG Humvee with VRCs can do their nevis thing (cloud-burning) and get through to the horizon IN such winds. With most kindest warmest kissy-poo regards, LOL, Hello, Len Thanks, but I'll pass on the kissy-poo regards ![]() You know, the few times we come close to arguing, I find that we are quite close to agreeing. I think a lot of the problem is that many get sidetracked over the great (if one can call it great) cw debate. The answer, of course, is to use whatever resources are available should one find themselves in such an unfortunate situation. The size of the asset that amateur radio becomes is most likely decided by the size of the area that is affected. That big NE ice storm a few years back (late 90s) affected areas for hundreds of miles. They were asking for mobile hf hams. I suspect that many hams in the affected area did loose their towers, but, as I mentioned, the smaller towers have the advantage of less wind loading (and less ice to support too). Mobile ops supplied a lot of help during that mess as their rigs and antennas came in from an unaffected area. HTs would not have helped (except in very localized support) as they don't have the kind of coverage needed. Many repeaters were off, some were still on, and at least one was pressed into use by the police (plugged their radio into the repeater coax). In closing, let me wish you best regards and pass on the kissy-poo ![]() 73 from Rochester, NY Jim AA2QA |

It's likely only a few lines are functioning, so a low bandwidth method
like text messaging would be perferred. So more users can make use of the limited bandwidth. |
