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. |

You can get close in (10 to 20 miles) via line of site or you get skip out to thousands of miles via ionospheric propagation when the solar flux is high enough. 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. |

And please notice that they weren't all in the local area either, as in Portland, Ore., and Utah. Washington Post: Communications Networks Fail Disaster Area Residents "But he spoke to a fellow ham in Portland, Ore., who found another operator in Utah who was finally able to reach operators in Louisiana. The radio operators in Louisiana got word to emergency personnel, who rescued more than a dozen people in the house, including Hayes's 81-year-old aunt." So how many people have you and your cb saved frankie? |

) 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. |

But there is often a great need to communicate within the surrounding couple of hundred miles. Dee D. Flint, N8UZE |

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. |
