| High strength unlicensed FM transmission? How strong could one of those FM "iPod adapters" broadcast? Would one that transmits approx 1/2 mile be legal?
I read about Title 47 CFR Part 15 which states something along the lines of "field strength of 250 µV/m at a distance of 3 meters from the antenna. This is equivalent to 0.01 microwatts" but I really don't know too much about radio broadcasting, but it seems like you need more than 0.01 microwatts to get such a range.

I've never looked for something like this, but I can't say that I've ever come across anything like it either.

Quick answer... Nope.. About 100' is the most a legal part 15 transmitter will reach without any interference. |

What is the effective range of an unlicensed FM transmitter when it complies with Title 47 CFR Part 15 and other relevant regulations?
I was stuck in traffic yesterday and there was a truck broadcasting advertising for over 1/2 mile.

kudos:1 | Over 1/2 mile range is a good indicator that the transmitter is operating beyond Part 15 limits. My Ramsey FM25B is about at the limit of Part 15 and it carries about a block, or maybe 1/4 mile into a very good receiver on a quiet frequency. |

Ahhhh.... Marketing people don't believe the laws apply to them.
Is it possible that while you were moving, albeit slowly, the truck was traveling in the same direction?

I was stuck in traffic yesterday and there was a truck broadcasting advertising for over 1/2 mile. Are you saying that some mobile truck was broadcasting over the top of a licensed commercial station? I can't believe any station would tolerate that for very long.

kudos:1 | Hopefully it wasn't broadcasting over a licensed station's signal. The FCC takes a very dim view of that sort of thing. They're more likely to respond quickly to an interference complaint than to a report of a pirate somewhere on an open frequency, especially if the interference complaint comes from the engineer or the manager of the licensed station. |

When I worked for a Major ISP, Marketing did whatever they wanted, and left it up to legal and the technical side to put the pieces together. To be honest, this does not surprise me that a marketing company would try something like this.
For instance... my former employer tried this :»www.techdirt.com/articles/201102···le.shtml
That screams of coming from marketing and I doubt the legal department was even consulted.

Not saying I like it, or defending it in any way...
It just does not surprise me in the slightest.

If they get lucky it'll be a NOUO (Notice Of Unauthorized Operation).
Of course once they get that or the NAL, they will try to place the blame on someone else who had no idea promotions were doing such stupid things.
The cool part is here in Florida, your first contact might be with the FDLE, or local law enforcement who will be slapping cuff's on them. Then the FCC agent walks up and let's you know oh by the way, when you get out of Jail we have this nice NAL for you. |

Huh? I doubt it.
Why would the local police even care? They aren't tasked with enforcing FCC Rules.

| As I said this is a Florida thing, I think New York now also has a similar law. The Pirate radio stations got so bad in South Florida and the FCC was unable to keep up they passed a law, and they will enforce it.
Normally when they go to enforce this law the FCC is aware of the pending action, or are with the officers making the bust.

Who is liable I wonder then if say a Part 15 device is functioning incorrectly and pushing into a licensed frequency without any post purchase hacking or alterations to the electronics.

If Part 15 device shall not causes malicious interference, either intentional or unintentional.
An extreme example: I woke up this morning, turned on my computer monitor (a Part 15 device), and it wiped out communications on the eastern seaboard. I would be required not to use my monitor until the problem was resolved.
It would be by the decision of FCC Enforcement whether to fine me or not. If I had not done anything to modify my monitor, and it 'just happened', it would be unlikely I would be fined. If it was intent to cause interference, or I continued to use my monitor after learning of the issue, then I would most likely receive a citation.

There’s a good article in Radio World this week which basically describes the FCC as a toothless tiger when it comes to illegal broadcasters, yes they can fine the pants off one, but in reality they seldom collect those fines and many pirates not only fail to pay the fines they thumb their noses at the FCC knowing fully well the FCC lacks the authority to confiscate equipment, shut them down and or collect fines unless the Justice Department and the U.S. Marshalls Office becomes involved.
