    It was analog cell phones. They took some of the top channels (70-83) from the UHF TV band to create the band for analog cell phones.

  5. Re:Tell that to Bikini Atoll... on Asteroid Flies Under the Radar, Literally · · Score: 1
    In space, a nuclear device can be treated as a black body radiator. Most of the energy is emitted as soft x-rays.

    On the Earth's surface, much of the nuclear device's energy is transformed into blast and thermal effects by a complicated set of interactions with the atmosphere. See Effects of Nuclear Explosions.

  6. Hall Effect Fans on SATA RAID Enclosure w/ Temperature Monitoring? · · Score: 1

    There are fans that have embedded Hall effect sensors that generate a pulse once per revolution. I've used them on embedded systems. Wire the sensor leads to a parallel port and write some software for a task that counts the pulses from the sensor and calculates the fan's RPM. It can generate an alarm if the fan slows down or stops.

  7. Re:A little out of place? on TV Over Phone Lines To Arrive In 2005 · · Score: 1

    The existing copper is totally inadequate for video distribution. I wouldn't expect any of it to be used. To compete with digital cable, they will need far more bandwidth than can be supported by DSL technology. They already have fiber to the neighborhood in many areas. They will need to install new equipment and cabling to get the bits from the neighborhood fiber nodes to the subscribers.

    Then you won't mind if I point a 100 kW CW CO2 LASER at your head? After all, it only emits non-ionizing EM radiation.

  9. Re:Rarely. on When Do You Read the Instructions? · · Score: 1

    Gun manuals can be ridiculous. I blame the lawyers. They enumerate every possible way that you could intentionally or unintentionally hurt someone/something, and tell you "DANGER: DO NOT PULL TRIGGER WHILE MUZZLE IS POINTED AT YOUR HEAD" and other such gems of gun safety. They stop just short of telling you to disassemble the gun and scatter its parts to the four corners of the Earth, otherwise you might shoot something with it.

  10. Re:Importance... on When Do You Read the Instructions? · · Score: 1

    I can think of useful information that could be in a manual for a cable. Things like grip the connector shell, not the coax, when removing a cable. Don't route the cable where it can be pinched, crushed, or stepped on. Don't expose to moisture or direct sunlight.

    It's simple. You have to ask yourself the question "How does this make money for the company or advance its strategic interests?"

  12. Re:Wow... on 6-Month Sentence for NASA Cracker · · Score: 2, Interesting

    I had something similar happen to one of my systems at work. They filled it up with porn movies and used the site's large amount of bandwidth to distribute them to lusers all over the world. For months afterward, I could see unsuccessful attempts to download the files in the logs.

  13. Re:I'd love to see a breakdown of the damages on 6-Month Sentence for NASA Cracker · · Score: 1

    It costs a substantial amount of time and money to take the system off-line, preserve the evidence, attempt to determine what was exploited, format the disk, reinstall the operating system, applications, patches, and restore user data. Then you have to write reports and try to determine if other systems were compromised. All the while, you are not doing your regular job.

  14. Radar Detectors on Weather Monitoring Frequencies Subject to Pollution · · Score: 4, Informative

    Radar detectors, and most radio receivers, do transmit low-powered signals on the same or similar frequencies to those that they receive. It's called local oscillator leakage/radiation. It's especially common in consumer grade electronics equipment. If you look at the block diagram of a superheterodyne receiver, you will find one or more local oscillators that are used to mix down the incoming signals to fixed intermediate frequencies for filtering, amplification and demodulation. These local oscillators are often a source of radiation due to poor design and shielding. Radar detector detectors and TV detector vans take advantage of this by listening for local oscillator radiation.

  15. Federal Regulatory Powers on Weather Monitoring Frequencies Subject to Pollution · · Score: 4, Informative

    The FCC has the power to ban the sales and use of any device that would cause interference to these frequency bands. I've owned radio transceivers that were made obsolete and worthless by FCC decisions to reallocate spectrum to other uses. The FCC had no obligation to compensate me for the loss in value of the radio equipment or to offer me other spectrum to replace what was lost. If car radar units are a problem, the FCC can prohibit their sales and use.

  16. Universal Service on Louisiana Towns Going High-Tech · · Score: 2, Insightful

    In past surveys, one of the major reasons that people do not have telephones is financial. Poor people often have bad credit, the telephone company wants all old bills paid before restoring service, the telephone company wants a large deposit, the head-of-household is unable to control usage of the telephone by other family members and visitors, and the cost is unpredictable. A typical scenario is that a household gets a telephone, the service gets abused for long distance and other premium calls, the household gets a large bill that they can't pay, the bill doesn't get paid, resulting in termination of service and a poor credit reference. Restoration of service would be expensive and would just setup the household for another cycle of abuse and disconnection. As a solution, some people have suggested requiring the telephone company to offer a fixed-cost service that would have permanent blocks for long distance and premium calls. The bill would be guaranteed to be $X a month, no matter how the phone was used.

    There wouldn't have been a problem if the Egyptians hadn't ruined the environment by building all those pyramids. Their per capita consumption of limestone far exceeded that of other human populations, leading to a significant increase in the albedo of the planet, and global cooling. The correlation of climate change with pyramid building is clear proof that it was their fault.

  19. Re:Cell Networks Depend on GPS on U.S. Makes Plans for GPS Shutdown · · Score: 1

    The government could require you to install cesium or rubidium timing systems in your cell sites so that they could continue operating in the absence of GPS. That's what many people used before cheap GPS timing receivers were available.

  20. Re:"Terrorists" on U.S. Makes Plans for GPS Shutdown · · Score: 1

    If I was a terrorist, I could make very effective use of GPS. Just buy or steal some JDAM-equivalent bombs, load them on a plane, fly over an area with high-value targets and chuck them out the back of the plane. One pass over Washington or London and you could devastate a long list of "secure" targets.
