By the way, NOLA isn't the only area that's ill-prepared for a Cat-4/5 hurricane. Look at the development practically anywhere on Florida's coastline (but especially around Tampa Bay), and up the East Coast through Georgia and the Carolinas.
About the only place where the barrier islands are allowed to function as they should is along the Outer Banks of NC, and even that in places (Corolla, Duck) is becoming condo-central.
To get a little more pedantic, audio is used to modulate the RF signal. The modulated RF is then transmitted to a receiver, where the signal is demodulated, the audio extracted, amplified, and then sent to the speaker(s).
But, still, wouldn't that have been easier by going to Arecibo or Green Bank? Granted, neither location will ever be confused with Cambridge, but still...
Besides, if they went to Green Bank, they could take a railroad ride during their spare time.
But the last thing I have heared they are still waiting for a green light. The planes,for the past few days, are just sitting there on the tarmac. It seems that your government doesn't seem to want any help.
I think the U.S. government is holding back on giving the go-ahead until it can be determined where the stuff needs to go. Right now, it appears (to me) that there isn't an absolute shortage of food, water, etc., but rather it's not where the people who need it are. And since Katrina affected only a relatively small part of a 1st world nation, it's probably faster to ship food, water, clothing, etc. from other parts of the country, instead of from overseas. And I don't know if you can airlift those big semi-trailers that convoyed to the Astrodome through 4 foot water.
There wouldn't be much point to send doctors and nurses, if there's no way to get them to the shelters. Ditto food and water.
Back in the 1990/91 Gulf War, there was a general (Horner?) who was in charge of getting all the "stuff" needed to wage a modern war to the Persian Gulf. Sounds like they need to find him, or his clone.
Perhaps they should just try to send more ham radio operators into the area.
The ARRL is now seeking volunteers for deployment to the Gulf Coast area, to assist with Red Cross feeding and sheltering operations.
The Amateur Radio Emergency Services exist to provide communications support the operations of governmental, health, and welfare organizations, such as the Red Cross, Salvation Army, etc. We do not operate as an independent entity, so while your idea of sending a lot more hams sounds good, without the organizations that provide search and rescue, food and water, shelter, etc., we wouldn't be much help.
Radio communications are infrastructure-free, over distances ranging from a few miles to thousands of miles (depending on band). -No need to find a local location with a connection to the landline Internet.
Amateur Radio operators are already trained and have drilled in disaster communications. -Experience counts.
Digital communications via amateur radio have been used for over 20 years. -No need to discover how to intall that WiFi card in a laptop.
Hams involved in emergency communications will likely already be properly equipped (extra batteries, DC-DC chargers, portable towers and antennas, personal supplies, etc.) -Look for SUVs with lots of vertical antennas on the roof.
The role of amateur radio operators in disasters is to provide communications services to the various relief agencies (Red Cross, Salvation Army, Local Emergency Groups, FEMA, etc.). We do not go in as a separate organization, but rather to assist those who have the training and expertise in relief operations. (Our expertise is communications.)
So only occasionally will ham radio be noted specifically... but every time you see a Red Cross van or Salvation Army truck, there likely is a ham as part of that team, providing comm's.
Interesting. Do you have any examples of places that did change their names?
IIRC, at first Pittsburgh PA had to drop the "h" along with everyplace else, but they raised a big stink and somehow got special permission from the Postal Service to keep the original spelling.
The students repeatedly broke the conditions attached to using the laptops. Various "typical" school punishments didn't work. Should the school just give up and let them have their way (with school property)?
Sure, a felony charge sounds harsh, but that's the law in PA. Don't think your employer won't turn you in to the State Police if you download pr0n to your computer at work.
Although that is a stickier situation, since there probably is a University-Student Housing Contract, which lays out a whole bunch of do's and don'ts (mostly don'ts as I recall).
There's that pesky word "amateur". As in no business use, no promoting of business use (such as surfing to a web page with an ad on it) or checking out the latest at Newegg, etc.
And a couple of decades ago, the amateur power limits were changed from 2kW input to the final stage to 1500W output from the final. Not that any of that's terribly relevant at 2.4GHz, for most of us anyway.
Since the same antenna is used for both transmitting and receiving, whatever gain is observed in receiving weak signals is also applied to the transmitted signal.
In effect, the antenna takes the energy that a simple monopole would transmit equally in all directions, and concentrates it in one (or occasionally two) directions. So the transmitted signal is higher in the favored direction (and weakened in other directions).
AFAIK, if a particular setup would violate FCC Rules and Regs, it's up to the FCC to enforce them. It's a subject that's strictly under federal regulation, not state police, not county sheriffs, not local P.Ds.
Will they go after copies of the ARRL Handbook next?
From the teaser, at least, it sounds like this was one informative email a week, for 12 weeks. Hardly characteristic of the spam that gets (most of us) upset.
Now what if they sent 5 or 10 a day, every day? Wonder if the test group would be paying attention to the message then.
Another advantage for Morse is that experienced ops (and these were) tend to think in words, rather than individual characters. The SMS 10-button keyboard forces the sender to think on a character by character basis.
At 30wpm (IIRC, that was the hams' speed, more or less), you hear words, even phrases, in Morse. By the way, 30wpm is well above average ham speed (especially since the licensing requirements were watered down), but at 50+ wpm, Morse becomes as conversational as spoken English.
I'm an alumnus of Tepper (GSIA, the old name, actually) and here's the email I received on Wednesday, April 20.
Dear ______,
On Sunday, April 10, the Carnegie Mellon Computing Services Office of Information Security identified a breach of some computers at the Tepper School of Business. Upon investigating and recognizing the unusual activity, Computing Services worked to disable, inspect and secure all servers and personal computers.
We have no evidence that personal information on breached systems has been used for illegal or malicious activities. However, the potential risks associated with identity theft are very serious matters, and the Tepper administration has chosen several precautionary steps to communicate with all affected students, graduate alumni, faculty and staff on safeguarding measures aimed at protecting privacy.
While we have not identified unauthorized use of information, we strongly encourage you to take steps to ensure your privacy. Personal information included in the databases that may have been accessed includes:
- For master's alumni Class of 1997 through the Class of 2004: Social
Security number and grades included in a student services database.
- For master's alumni Class of 1985 through the Class of 2004: Job offer
information you may have entered into the COC database as part of your job search process.
- For all alumni: Contact information you may have entered into the alumni
directory/alumni database. (Note: All Personal Access Codes (PAC) for the alumni database have been automatically updated for increased security. Your new PAC number is: **********
Your email address in the directory is: ****************
- For doctoral alumni Class of 1998 through 2004: Social Security number,
GMAT, GPA and information submitted in your application to the doctoral program.
Please visit www.tepper.cmu.edu/******* for information regarding precautions and steps to take to protect your personal information.
We apologize and regret the inconvenience associated with this incident. Currently, the business school is in the early stages of investigation and does not have all details regarding the source of this breach. As further information is discovered, we will be sure to include it on the Web site listed above. In any event, please understand that we would not disclose details that would put any computer or network at risk of further intrusion or malicious attack.
The recent Tepper incident is similar to the computer breaches reported by other universities. As a campus that prides itself as a hub for technology innovation, Carnegie Mellon is extraordinarily mindful of issues regarding information security. The recent breach is a reminder of the sensitive business environment in which we operate and the need to consistently monitor and advance our infrastructure and processes.
If you have questions or concerns, we encourage you to contact John Sengenberger at jseng@andrew.cmu.edu
Bankrupt just means a company's current assets (cash) aren't sufficient to pay its current bills. Bankruptcy (under supervision of a judge) actually allows a company to get off paying some of its debts, thus increasing its worth.
K-Mart, for example, came out of bankruptcy in good enough shape to buy Sears.
In the U.S., no Federal Tax is paid on stock appreciation, although some states have Personal Property Taxes that are based on an asset's value, which would increase.
A stock's appreciation is only taxed when the stock is sold, and a capital gain (if any) is realized (that is, converted to cash). That is, if a stock doubles one year, and halves the next, a U.S. taxpayer who has held the stock through the whole up-and-down cycle has no (federal) tax liability.

For really rural, drive 3 hours south to the east-central part of West Virginia (Pocahontas County, for example).

Especially since, at least here anyway, it's only Saturday morning.
So the ERP of sending an 80mW signal to a 12dB gain antenna is not going to be 12*80, but something *much* larger.
And a couple of decades ago, the amateur power limits were changed from 2kW input to the final stage to 1500W output from the final. Not that any of that's terribly relevant at 2.4GHz, for most of us anyway.

I was wondering what the automotive connection with armadillos is, although I imagine the Grand Challenge vehicles will be using automatics.
Now what if they sent 5 or 10 a day, every day? Wonder if the test group would be paying attention to the message then.
