    If he is a licenced ham radio operator, I doubt the amplifier is using is in any way "illegal".

    I'm not sure what the maximum power output is in the United States, but here in Sweden, a licenced radio amateur operator can put out up to 1 kW or so without any additional license.

    And, being a ham radio operator, you don't actually have to use equiment certified by anyone. Part of the reason you have to take an exam to become a ham radio operator, is to demonstrate they you know what you're doing. Amateur radio is the only service I'm aware of (other than possibly the military) that doesn't require its users to use type approved equiment.

    Now CB radio however, that's a completely different story. Any idiot can go to his local electronics store and buy himself a CB rig capable of putting out 5 W of power with a microphone and jabber into it.

    Now if he is a CB radio operator -- if he's using any amplifier at all, it's probably very illegal -- and usually of poor quality with lots of nice harmonics.

    So how can you tell if your friendly neighbour with the amplifier is a licenced radio amateur running QRO on HF, or if he's an illegal CB operator?

    Well. One way to tell is by the way he talks on the radio. You said that you have equipment capable of receiving his transmissions (your computer speakers :-)

    According to regulations, all amateur radio stations must identify with their callsign and the callsign of the other party on a regular basis in their contacts. Listen for callsigns -- usually 5-6 characters long with one or more numbers in it -- my callsign is SM0YUF, somebody in the US would probably have a callsign starting with A, N or W, or maybe some other letter that escapes me at the moment. You can look up who owns a certain callsign on http://www.qrz.com/.

    If the transmissions contain no callsigns whatsoever, chances are that he's in fact an illegal CB operator, in which case, in theory, you could contact the FCC using the magic word "CB" rather than "ham radio", and hopefully you might make some progress.

    Hope this helps. Oh, and do look into those papers with toroids and ferrites. If he is in fact a licenced radio amateur, he is well within his rights, and your equiment is shoddy. Sorry.

  3. Freeform! on Address Formatting for International Mailing? · · Score: 3, Informative

    There's nothing more annoying than forms that require you to enter your address in a specific way that doesn't fit for that particular company. If you're shipping to only one country, that's fine, but otherwise:

    What's wrong with just letting the user enter the address in a freeform text field? The user probably knows what his own address is, and can write it in a form that the local post office can deliver to. Just include a dropdown box for the country, and that should be all there's to it.

    Except uControl uses a modifier key to change between scrolling and non-scrolling, allowing you to use the entire trackpad for that purpose, and SideTrack wants you to scroll using the edges of the touchpad, which is prone to misactivation and gives you less freedom.

    Or does SideTrack have a uControl like mode for that now? I don't know. It didn't last time I checked the program out.

    Scrolling itself is the same I guess, but the actual UI is different.

    Bah. Okay.

    Unicomp sells a keyboard called "On the Stick", which is a 101-keyboard with trackpoint goodness. Here's a link to the catalogue page.

    As an added bonus, it will give you buckling spring goodness, as previously seen on keyboards like the IBM Model M.

    I haven't tried the keyboard myself (I hate trackpoints, I'm a touchpad person myself), nor have I tried their specific implementation of the buckling spring mechanism, but my PC does have an IBM Model M keyboard connected to it. Type hard or go home! ;-)

    Hope this helps.

  8. Re:Reinvent on RollerMouse Aims to Replace the Traditional Mouse · · Score: 1

    Yeah, and I still haven't heard of smooth (as opposed to notched) mouse wheels *searches Google to make sure*

    Actually, these exist. I distinctly remember buying a crappy PS/2 mouse at Clas Ohlsonwhich featured a notchless scroll wheel like you describe. I'm not 100%, but I think it was manufactured by A4Tech.

    It was pretty annoying though. It wouldn't let you scroll pixel by pixel. The "notches" were still there, but implemented by software.

    Not to mention, I prefer a mouse that doesn't scroll just because I look at it the wrong way. It'd be way too easy to scroll by mistake.

    Another idea I've seen, is a mouse (also made by a cheap company, Typhoon. It used a trackball for 2-d scrolling. God, that was annoying! It was rather uncomfortable to get that scrolling straight and not jumping left and right all the time. Also notchless, and thus way too easy to trip.

    My conclusion? Notchless is a bad idea if you want to implement a scroll wheel. The notches are there for a reason. Actually, I'm pretty much sure that you could modify several popular scroll mice to make them notchless, as the few I've opened actually was using optical sensors to detect motion rather than switches, anyway, and the notches are only there to prevent spurious scrolling.

    The best scrolling mechanism I've used is on my iBook. I use a third-party tool called uControl to enable scrolling using my touchpad. Unlike SideTrack or similar Windows drivers, uControl will let you use your trackpad for mostly stepless 2D scrolling, when depressing the Fn modifier key (or other modifier key of choice.) Very handy.

    Hope this helps! :-)

    So you can tell wget to lie to the web server when raiding your favorite web page for images.

    That's not what the person asking the question asked for. He wants to stop sites from deep-linking his jpegs, not protect his nuclear launch code CGI to be used only from his own home page.

    A simple filter which would require the referer to be on his web site would pretty much stop his problems anyway. The people deep-linking to his web site write their web pages for browsers with <img src> tags, and as far as I know, you can't in HTML tell the web browser to fake a referer header. Then again, I'm not a HTML-head...

    And it's not really practical to tell your user to use wget to download your web site either. :-) At that rate, it's probably easier to mirror the image. Problem solved.

    Assuming for a moment that cell phones cause cancer -- something of which I'm sceptical to say the least.

    I think the maximum legal output is somewhere around +15 to +20 dBm in the 2.4 GHz ISM band which is somewhere around 30 to 100 mW.

    Which is a little lower than the maximum power of 2 W (IIRC another figured pulled from my ass here, but I think it's pretty accurate) which a GSM phone can put out legally.

    Now, in the city, most GSM phones will cut back on the power anyway to save the battery. But 2000 mW is still a lot of power compared to 30 mW or so.
