Yes, it goes, as I understand it, far enough above 30 MHz to interfere with public service bands. I've been a ham since 1958 and can well appreciate how, in the HF spectrum, a little bit of RF can, at times, cover huge distances. I've talked to Japan and Australia with 4 watts and a 4 foot loaded antenna on the trunk of my car at 14 MHz. If BPL ever (shudder) gets widespread, it's going to screw up a lot of the spectrum far beyond the near-field distances.
Telephones and the Internet are great, but depend on a lot of infrastructure that is very vulnerable to natural or man made disasters. Radio is still the only way to communicate over significant distances with relatively simple, self-contained, battery powered equipment.

with more than a few students has, at one time or another, had a carrier current AM broadcasting station. Eventually, a lot of them moved to low power FM so as to get stereo and better fidelity. Just do a google for "carrier current" and you get a lot of hits.
Additionally, the power companies have used it for decades for a variety of purposes including monitoring and control functions. These uses were not problematic as they were on a fixed frequency and so did not interfere with other existing radio services. The broadband nature of the RF generated by the proposed BPL applications spews energy across a broad spectrum and therein lies the problem.
During WWII, hams were not allowed to transmit "on the air", but limited power "carrier current" transmittion was allowed and appears to have been popular given the construction projects I recall from reading the 1944 ARRL handbook in our small town library. This operation was, as I recall, around 150 KHz and sometimes, depending on the location of transformers, could cover a few miles.
I don't see why this miserable technology hasn't died a natural death. It's like the monster in the movies that just won't quite die. Power lines are designed to carry power and become antennas at higher frequencies. It's as simple as that.
I am an admitted Mac Noobie having had this venerable G3 Imac for a short time. I knew it was one of those cat names. It's actually OS-X 10.3.9 that I am using.
I thought it was time I got some exposure to OS-X after being a Windows and Linux user. This G-3 came from a Good Will store and set me back all of $30. Still playing and learning.
The Mac version of Opera works great, too. I've got four browsers on my old iMac G3-333 that runs Tiger. IE, Safari, Firefox and Opera. My linux boxes have Firefox, Opera and Konqueror. My bank's site gives me a non-supported browser warning when I access their site with Opera, but allows me to proceed and, other than some minor rendering problems, works OK.
The author of this article is clearly not very well educated technically. We really need to know how many watt-hours are generated by a given vehicle. The instantaneous power, measured in watts, is not particularly relevant without the time duration that it's available. For example, 10KW for 1 second is only 2.8 watt-hours, (10000 watts/3600 seconds per hour), meaning one actuation of the ramp producing 10,000 watts for 1 second, could power a 2.8 watt light source for 1 hour, assuming 100% efficiency in energy storage.

misleading there. Perhaps "Specialized" would have been better, albeit, specialized software tend to be proprietary, too. What he means is that the industy-specific software for his situation and, indeed, most analogous ones, is written for Windows. That is true in my industry, too.
Because software packages like this are written for a focussed and relatively small audience, they are unfortunately, by nature, proprietary as in not free in either the beer or libre sense. I'm afraid that the incentives just aren't there for the FOSS effort to materialize yet. The lack of a Linux accounting package comparable to Quickbooks is a good example. Not saying it never will and, as Linux continues to make inroads into the general purpose desktop business market, then the incentives for software producers to port to Linux will increase. It's going to be a slow process, but the flow is now starting to move in that direction. As much as some people would like to have all software FOSS, I doubt it's going to happen any time in the near future. There will always be a need for some special purpose, custom, software.
I just got my first Mac since the original one that didn't have a HD, back in the 80s. It's an iMax G3-333 with 256 Megs of Ram and a 12 Gig HD.. It cost $30.00 from the Good Will store. I've got OS-X 10.3.9 running on it and it's a very nice useable machine. I see iMacs on eBay for well under $100 (not including shipping). Give one a try. I'm really enjoying mine.
I assume that means precautionary against being sued even more than they are being sued now. It's being "temporary" is certainly not precautionary in relationship to the customer and is a bit more than a little ominous.
The music and video industry needs to realize that their business model is out of date with technology and they can't put the genie back in the bottle. This sort of adjustment to new technology is hardly new.
* The telegraph/telephone, depending on the year was going to destroy the postal system. That didn't happen. Technology moved forward.
* When radio broadcasting came along in the 20s the record companies would not allow records to be played on the air since it was a copyright violation and would destroy the industry. That didn't happen. Technology moved forward.
* When tape recorders came along they had a fit because it would destroy the music industry. That didn't happen. Technology moved forward.
* When Betamax recording came along they fought it tooth and toenail since it was going to destroy TV. That didn't happen. Technology moved forward.
Time for technology to move forward again and forget about this silly DRM crap that tries to take away our Fair Use rights.
I'm in the elevator business and we run into that a lot.. I like it because it's actually 120vac from each leg to the neutral. In our business it can eliminate control transformers that supply the 120 to operate the control devices. Controller ground = the neutral.
It's nice, too, when you rectify it as you get a relatively low ripple 275 dc without further filtering, which is convenient for running the door operating motors and the drive motor fields if you are using a DC drive motor.
that they released, as in GPL, their own Linux distro a while back. Once you release the code under the GPL, there's no taking it back. It's out there and available for anyone to use under the terms of the GPL. I am at a loss as to why this hasn't been hammered on to put an end to this sham/scam that SCO is trying so desperately to pull off. This release of the source code as Caldera eliminated in my opinion, lets IBM off the hook in that regard.
Then, of course, there's that nasty little detail wherein SCO/Caldera never owned the copyrights anyway.
Really, the ads are very small and don't bother me. I did use the free registration to see what it looks like without the ads. I still don't think the ads are a big deal.
This browser has come a long way since I first tried version 2.0 on Win95. That was clunky and I uninstalled it after a couple of days and went back to Netscape. I tried it again around 5.X and liked it a lot better. I stuck with it and now use it as my main browser on multiple platforms, but I also use Firefox, Konoqueror and Mozilla as well depending on what I'm doing.

last week to use a legacy program on it and was surprised at how quickly it booted up. I also noted with some interest that the 1 Gig HD was only half used, even with some applications installed. As I navigated around the HD with Windows Explorer and moved some files, I further noticed that it didn't really feel any different than using XP. Then I loaded Firefox and connected to the Internet via the Linksys Pcmcia ethernet card and found that browsing didn't feel much different either. Somebody want to explain again how far we've come in the past 10 years with Windows? Sure there are some conveniences and minor improvements, but at what cost in bloat and memory requirements?
I just checked the stats on my relatively busy web site and saw that of the 16,640 Windows machines that visited last week 94 of them were using Win95. Just below that was NT with 42 visits and WIN32s with 10 visits. Oh, I even saw one single OS/2 visit..
since 98 or ME systems will read it, whereas on those systems I'd have to install a driver for the USB flash drive. Almost any machine is going to be able to read a CD these days. Oh, I also carry a Knoppix live CD with that, too, for the really bad cases that won't even boot Windows.
My 1 Gig flash drive, like yours, has PuTTY along with my installation of Eudora 5.1 for my main e-mail address that runs from flash so I am carrying my e-mail archive and client with me that will run from any XP machine at hand. I actually have the latest Firefox install and a few other utilities on the flash, too, with enough room left over to salvage files off a dead Windows machine when I boot to Knoppix. It's my electronic scratch pad, so to speak.
I know that some would be concerned about running an executable from flash given the published limited write cycle stats, but I used the 256 Meg version before I got this new one for over a year on a daily basis without a hitch.
Just to be safe, though, I have a program on my home machine that does a backup to our home network file server at midnight every night and then the file server runs a backup to a USB hard drive at 2:00 a.m. Same thing for my wife's computer. Anal retentive? Maybe, but I've been bitten a few times before I had an automatic backup in place.
I've downloaded a single time and installed on multiple computers, some via network and others not on the network by using a "Utility" disk that I carry with me to install certain applications without having to go online unprotected when I'm cleaning up a compromised system or getting a new one ready to use. Some of the other applications on that CD are, Ad-Aware, Spybot, AVG antivirus, Zone Alarm firewall.

No, it's not "Real-Time" but it suits our needs in our home office situation.
I use "Smart Synch" software to incrementally copy the desired directories from the working computers to a "Backup server", an older Celeron machine on the network. Separate partitions are set up for each computer that is being backed up. At Midnight the incremental backups are made.
Then at 2:00 a.m., Smart Synch running on the backup server makes another backup to a USB hard drive plugged into it. That USB HD is on a regular plug-in timer so that it only runs during the time of night when a backup to it is being done. The idea there is that the running time is limited and drive life is extended. Weekly, a backup DVD is burned and stored off site. Am I being anal? Maybe.
I agree that there are always a few rotten apples. Over the 48 years I've had my license, I've observed a few of them, too. For the most part, the Hams do a pretty good job of policing their own ranks whenever possible. It's certainly to our own benefit to do so.
The hams were most likely in complete compliance with FCC regulations. The fault is in your appliances that were poorly designed so as to be susceptible to external interference. Most hams are more than willing to work with interference complaints and help you install proper filters on your equipment. See the ARRL information about interference here.
This is also one of the reason that I use code in conjunction with low power so as to avoid this sort of problem. The other reason is that it's so much fun.
I am in agreement with the other poster who proposed that the code requirement be lifted except for the Extra class license. That way the majority of licensees would have HF (Shortwave) privileges without having to learn code.

I don't have digital cable and really don't want it. We have a large house with a lot of rooms so I run a distribution amp to send the signal the 7 sets scattered around the house. I don't want to have to get 7 digital set-top boxes so I get only the analog cable offerings and even that is more than I really want, but they package the channels I do want with junk like sports channels that nobody here ever watches.
If they want to add digital channels as they have along with existing service, that's fine, but why send mega numbers of suddenly obsolete TVs to the landfill? There are a lot of people who can't really afford new TVs either.
I'm sure there will be set-top boxes, but they'll probably cost as much as the smaller TV's do new. I remember having an old VHF only set when I was a kid with a UHF converter box to get those newfangled UHF channels. So I suspect the same thing will apply during this transition.
