      You're not kidding.

      I live on a street where these assholes like to drive up and down while bassing. Well, one day, I got really pissed. I'm trying to work in my den on a project and the constant noise just won't stop.

      So finally I follow one of these guys to see where he ended up. I honked my horn rythmically as I drove by.

      Next thing I know the guy is chasing me around trying to run me off the road. I called 911 and get, I not am sh1tting you "we're really busy right now" and I'm asked to call another number where I'm put on hold listening to how my city has this great new newsletter. "Please download Adobe Acrobat Reader to view the newsletter".

      Finally someone comes back on and tells me I might as well drive to the police station. Hey, great idea. Lots of police there. Well, that doesn't stop him.

      I sit in the police parking lot for 30 minutes while this guy tells me how I'd better not do that again or I'll be sorry. He is insane.

      Oh, the FIRST time I followed someone, they took me into da'hood where I drove through what looked like a riot and was almost hit by a driver fleeing police. You'd think I would have learned the first time.

      The really depressing thing is realizing that I'm essentially powerless. People can be a55holes and threaten your life and you can't do anything. Why? Because I have to follow the law while they have nothing to lose.

      I later went back to look at the laws in my state governing self-defense. They are totally impractical. The legal system is set up in such a way that you really have to let the animals control the streets.

        It's called prioritizing. "Deal with shooting or deal with guy who's being followed by some teenager punk. Hmm." "I am not sh1tting you", 911 is heavily abused. Sample calls, according to dispatchers I've spoken with: "Hi, do you know the number for ____?" "I lost my dog..." "Can you give me directions to...", then the ever-popular hangups, which of course they have to investigate, tying up an officer's time. Then there are shut-in bitches who tell war+peace about the neighbor's [dog barking/yard mess/porch lights on/you name it]. The list goes on, and on, and on.

        Most police departments are also pretty short-staffed these days. Bush is mostly responsible on two counts; 1, for cutting back on federal funding for local emergency staff- police, EMS and fire all have been hit hard in almost every town throughout the US. 2, a large percentage of Guard and Reservists are (surprise!) also town/city fire fighters, police, EMS, etc.

        I later went back to look at the laws in my state governing self-defense.

        How about looking up the noise ordinances, instead? Most cities and towns have 'em. NY, for example, is getting very tough on noise complaints (I believe you dial 311, ie the non-emergency number?) Borrow a neighbor's video camera (they'll be happy to oblige if it's annoying them as well) and videotape the clown going by- be sure to get a closeup of his face, and his plates. Call the NON EMERGENCY ie business number for the local station, ask to set up an appointment with an officer or detective. Problem solved and out of your hands.

        Next thing I know the guy is chasing me around trying to run me off the road.

        Um- duh. Get away from him, file a police report later with the plates and vehicle description. You've also hit upon why I carry a Bronx Calling Card, aka 3-D-cell Maglight, in my front door pocket. I have been doing so ever since someone told me they'd "fucking kill me" at a stoplight when I told him he his highbeams were stuck on. This was, incidentally, in downtown Larchmont, NY(very swanky neighborhood), the guy was not driving a riced out POS, and he was white.

        One of many reasons I moved out of NY state- everyone's a prick out to kill you at the drop of a hat.

        • They are too busy chasing me down because I don't have a front license plate.

          I've been pulled over twice in the past seven days so I think it's time to finally give in and install a bracket and the plate.

          The second officer was very authoritative but seemed respectful enough so I asked him what the purpose of a front plate was and if it was suppossed to make it safer for officers. His response was something like, I have no idea, I think they're silly but the law states you have to have it so you do.

      I have an iPod and an iTrip, and the article doesn't make much sense based on my experience. The iTrip is an extremely low-power device, and even when you're using it the way it was intended, to broadcast to your own car's antenna, it's actually too weak to override a commercial station. That's why the iTrip isn't all that great in an urban environment, where the whole commercial FM spectrum is packed with stations like sardines in a can.

      First, to become your own pirate broadcast station you'll need to increase the range and signal of your iTrip mini. Turns out, there is an antennae built inside the iTrip mini. All you need to do is remove the top sticker-like protection which hides the antennae and then using tweezers or your fingernail, pull the antennae out. We've found a 20% to 30% increase of range on average.
      Huh? A 25% increase in range is only equivalent to a 50% increase in power (the inverse square law). I can't see how a 50% increase in power is going to matter, when our iTrip has never been able to override even the weakest station on the dial.

    How-To Tuesday: Make your own Pirate Radio Station with an iPod

    Posted Jun 15, 2004, 11:07 AM ET by Phillip Torrone

    Related entries: Portable Audio, Wireless

    This was going to be "How-To increase the range of your iTrip mini". But after playing around with the new iTrip mini, the FM broadcasting accessory for the iPod (our review here) our little minds got working on some ideas. We thought we might be able to make the range of Griffin's iTrip mini a little better if took it apart and exposed the antenna, turns out we could. And then we thought, hey- we could use a couple iPods to broadcast something we wanted to get out there, perhaps not "should" that is, but could. So that was our motivation, and here's the How-To.

    Ingredients:

    * 1 iPod mini

    * 1 iTrip mini

    * Optional: Addition iPods, iTalks and iTrips

    Getting Started

    First, to become your own pirate broadcast station you'll need to increase the range and signal of your iTrip mini. Turns out, there is an antennae built inside the iTrip mini. All you need to do is remove the top sticker-like protection which hides the antennae and then using tweezers or your fingernail, pull the antennae out. We've found a 20% to 30% increase of range on average. This likely voids the warranty, so there, we said it.

    Next up, if you're using the iTrip mini, then you know that you can install all the stations on the dial to broadcast on. At first we we're really sure we'd ever use them, but now we have good reason. So make sure you've installed all the stations, on the go you might need them to switch to. Remember, the iTrip is a FM broadcasting device, intended to broadcast 10 to 30 feet to a FM radio.

    Next, choose your broadcast, it can be any song or a spoken word MP3, don't worry we have a few suggestions. A lot depends on the situation you're in.

    Pirate Broadcasts

    We usually keep a couple tracks of silence ready to go, ever get stuck at a stop light for like 10 minutes and the dude in the next car is blasting the radio? With the super easy iPod interface you can quickly get to the station he's on and send over whatever you want, a couple gentle ocean waves or birds usually works out great.

    If you've ever gone to the Gym, or starred in to one from the outside- you'll notice the TVs are muted and set to broadcast on specific FM frequencies, folks then tune in their radio headsets to whatever station to listen to the audio as they exercise. Now we're not suggesting you go around and broadcast over CNN or anything, but we think broadcasting "Aliens have landed today, the President and UN will be making an announcement immediately" could be quite fun. We'll be trying this out with our gym pals who are usually up for a good gag.

    There are other times where you simply need to broadcast back. Let's say you're at the park, enjoying a nice quiet day with your family- then comes along someone blasting the radio. We've found broadcasting a silent track tends to work nicely, sure you need to be within 30 to 40 feet, but no one will even suspect that their FM broadcast is getting usurped by you.

    Advanced Pirate Radio Broadcasting techniques

    We've also discovered another fun example. If you use the iTalk, Griffin's voice recorder accessory with 2g/3g iPod you can record your pirate broadcast on the fly, pop in the iTrip and start broadcasting. Usually pretending to be an omnipotent being and asking folks to build a water proof car, drive across the English Channel with two of every gadget gets some interesting reactions.

    Now, if you really get in to this- you could easily increase the range even more, google around for ways to do this- we're working on a few and will let you know too. You can additionally use multiple iPods, when you're broadcasting something like a silent track, you and a pal can cover more area and really surround the FM receiver. And finally, there are also a lot of other things which use FM that you can discover and broadcast to, happy hunting.

    This concludes our broadcast. Send comments and ideas to torrone@gmail.com

When you can get 20 mile range by putting a hand made antenna in a tree connected to a hand soldered rig causing no interference to any other spectrum users (like you can learn to do from these [freeradio.org] people) I'll be more interested.

    Sorry, folks, but if you put your little iPod transmitter up against the giant commercial transmitters, the giant commercial one is going to win.

    Bear with me, I'm not going to go into details when I can't draw pictures.

    If you have two signals at the same frequency arriving at the radio at the same time, they'll overlap, not cancel. Let's say you're broadcasting the "blank" signal at, say, 100 MHz. The radio will receive a constant 100MHz signal.

    The way FM works is by changing the phase of the broadcasting signal in relation to the unmodulated signal. So, you'll get the silent signal (which will be unmodulated) and the real signal (modulated). The radio will process BOTH signals - they use processors to decode the signals. I don't know if you know this, but they're kind of fast now. They can handle multiple singals.

    If you broadcast another audio signal, you'll get the two audio signals overlapping. Keep in mind that you're putting your tiny little iPod wire up against a great big dirty commerical broadcasting antenna. If you win, I'd wager that the Feds are going to want to ask you a few questions.

    They haven't done this in real life. If you say you have, then you're lying. Of course, I'm just an Electronics Engineer - what do I know?

    What's next, accepting articles from weekly world news? This isn't fark.

      Ever here of the inverse square law, and the FM capture effect? At close range you only need a tiny signal to swamp a moderately distant commercial station, and the FM capture effect means that the signal that is slightly stronger, will be the one that you hear, not the sum of the two signals.

      I'm sorry, but thanks for playing our game. Your description is completely incorrect my friend. FM has the "capture effect" wherein only ONE signal can be properly decoded.

      Which ever signal is strongest at the receiver will "win" and be heard. If the signals are too close in strength, you won't get either properly.

      With a commercial transmitter putting out several KW's but being 50 miles away and you putting out 100MW but being several yards away it is quite possible you will win out.

      BTW, this is exactly what these products do. You don't need to be on an unused frequency (trying finding one of those in the Bay Area) Of course it helps quite a bit if the commercial signal is weak and easier to overcome.

    I thought this was odd, because it cut in suddenly and clear as a bell.

    I then noticed that the closer I came to the Cadillac in front of me the clearer the signal became, and at certain distance from the car NPR would cut back in.

  • "Pirate Radio" implies a high-powered transmitter (such as from ships off-shore or moving vehicles) trying to evade detection, being used to beam signals in an area at strength levels far, far in excess of the unlicensed threshhold.

    This type of transmitter generates at or below the 100 mw permitted for completely unlicensed radio transmissions by FCC regulations. It is not "pirate" as this form of unlicensed radio transmitter is completely legal.

    • 100mw is not permitted for FM unlicensed radio transmissions per part 15 of the FCC regs. For part 15 they go only by field strength at a certain distance from the antenna. 100mw into anything better than a dummy load will be way over the limits. Even the 25mw transmitters sold by Ramsey Electronics will exceed the limits in most cases.

    Your're not gonna silence the other guy's loud car stereo, instead you're gonna launch him about 40 feet into the air! The FCC might tend to frown on you if they see you doing it; If you want to rule the airways for several blocks around your vehicle on all frequencies AM and FM simultaneously, and even screw up the guys CD audio, just build a spark gap transmitter and transmit either CW or voice (if you could call it that). The more RF output power the better! You could even connect a dynamotor to your auto fan belt (run it in tandem with your generator) and pump out 1000 watts+ RF! Then you'll bring the whole bay area to its knees! I think you might want to place your iPod in a well shielded box or just leave it at home while using the spark gap. This is technology from the 1920's !! Here's a sample schematic: http://w1.859.telia.com/~u85920178/tx/sparky.htm Oh yeah, be real careful - RF burns are no fun.

I went to the site expecting to find perhaps some hardware hacking info on the iTrip for boosting its output, or something like that... but come on now... has slashdot really gotten to the point where "if you pull the antenna out of the case, your signal will improve!"

    I mean, really. That whole thing did not take any bit of genious, or even the slightest bit of creativity. Geez... thats what the iTrip is for. Broadcasting... and it isnt the best around for that either... there are better version, and in fact, you can even get fm broadcaster kits with a good deal more transmit power than the iTrip has...

    But still, I dont see whats so special here. They are using an iPod and an FM broadcaster to do exactly what they were meant for... nothing new or special here.
