Title: arduino +100Mhz radio jammer
Post by: S_Flex on Feb 21, 2013, 02:21 pm
Does anyone have some links or projects of jammers that are powered by an arduino?

NOTE: Before you come posting on this thread about it being illegal. I know the laws and where I'm from (USA) it is not illegal to use a jammer on your privet property as long as the jammer does not exceed your property line. Go look it up if you think I'm wrong!

where I'm from the federal laws say its illegal, but the state laws point to it being legal. Even laser jammers are legal where I'm from.

Isn't it funny how the state of California legalized a federally band substance? Then told the federal government that law dose not apply here. That's because the states tell the federal government what to do its always been like that and it has to stay like that. Unless you want to be a slave.

The FM radio band is around 100MHz.

So lets say for sake of argument that it is legal to jam radio frequencies on your own property, which it's not, state laws are superseded in these situations.  For instance you can be arrested by a DEA agent in California for smoking marijuana even though is it legal there.  How are you gonna keep the jamming to just your property?  I'm gonna go ahead and say it would be very difficult to do if not impossible.

That being said if you wanna brake the law that's your prerogative.  By definition a radio jammer decreases the signal to noise ratio of a given broadcast.  You do this by increasing the noise as you have no control over the signal.  So you need a way to create noise and a way to transmit that noise.

The FCC regulations preempt ANY state attempt at regulating federally licensed communications systems.  You are being fed patently false information that your state/city/county/dog catcher/mayor or ANY other entity can regulate federally licensed communications systems.

As for your failed attempt at equating marijuana laws, I will just leave this here for your perusal http://www.sbsun.com/ci_22532373/authorities-raiding-multiple-san-bernardino-medical-marijuana-dispensaries (http://www.sbsun.com/ci_22532373/authorities-raiding-multiple-san-bernardino-medical-marijuana-dispensaries)

Good luck with your jammer.  I'll be watching the FCC enforcement logs for when you get your arse handed to you for using a jammer.  BTW, the fines START at $10,000 PLUS jail time.

I don't know where you get your legal advice but your source is just plain wrong. The FCC (F as in Federal) has all jurisdiction of RF laws, the States have absolutely no jurisdiction to change or even supplement the FCC rules and regulations.

I think your best bet would be a big ars Faraday Cage. Else you would need to create a  type of frequency generator and the Arduino inst going to help you there short of using it to control timing of the generator. You need to generate a 100mhz signal that on your property would be stronger than the signal coming onto your property.  Only issue is and I cant stress this enough. The FCC overrules your city and state government.

It would be kind of interesting if it were up to the states though.  And by "interesting" I mean nearly impossible to use. Having your OTA TV signal go to crap because someone in the next state over is using that frequency for their wireless network. Makes me wonder how they did it in Europe. If they had the foresight to set up international standards first, or if they waited till something FUBAR'd.

well first of all the only FCC law that can be found on jammers only specify cell phone, wifi, GPS and radio bands that company's or people own. On the wiki it states that the law is not enforced by the FCC, since no one has been charged with the crime.

On the other hand I just wanted to see how it was done and I had no malicious intent(believe it or not). I could have just asked how to turn the arduino into a FM transmitter as easily as asking how to make a jammer.
Anyways I figured it out so most of you just waisted your time bickering and talking none sense.

The FCC would be totally silent on the human rights issues to do with that, and the medical ethics and medical technicalities of performing the necessary procedures. But somewhere in their regs they'll cover the radio-related technicalities such as frequencies and powers that such devices may use. They might even remain silent on referring to a device called a "RF ID tag", but the transmission of any radio frequencies in the whole of the RF spectrum is covered by the FCC's regs and therefore so are RF ID tags, even if they don't name them as such.

So what was the point of your question?
Title: Re: arduino +100Mhz radio jammer
Post by: laadams85 on Feb 23, 2013, 03:27 pm
There are ISM bands that are unregulated.  This is commonly the 2.4GHz band and the 915MHz band in the Unites States.  There may be others but it is not something I worry about too much.  This is why pace makers are always a concern around microwaves etc.  RFID operates in these unregulated bands.
A state banning implanted RFID is adding restriction on top of federal restrictions.  There is nothing wrong with that.  What a state cannot do is allow what the government does not allow.

The FCC can do nearly anything it wants within it's mandate as codified in federal law. So what is point, that you will be asking and expecting the FCC for a permit to operate your FM broadcast jammer? I didn't think so.

One can operate a FM transmitter of a certain low power limit (covered I think by FCC part 15 rules, 100mw or less?) without prior permit or license. However if that ends up interfering with your next door house's FM reception and they complain to the FCC and if their is nothing wrong with their FM receiver the FCC will come knocking on your door to stop you from transmitting your part 15 device.

Stop wasting your time folks.  Those of us that hold several FCC licenses, myself being Amateur Extra Class as well as GROL+RADAR, as well as being a COLEM and VEC, obviously know nothing about communications regulations and the OP is the world expert on all things communications related.

FCC not enforcing jamming regulations?

Stick those in your "wiki"

As for RFID devices, the FCC regulates the RF part of the device.  They have nothing to do with whether or not someone can implant an RFID device in the human body.

The ISM bands ARE regulated under part 15 of the FCC regulations.   In the early 1990's the Federal Communications Commission (FCC) allowed using three of the ISM bands for unlicensed communication equipment.  These three ISM bands are:

902 to 928 MHz
2.400 to 2.4835 GHz
5.725 to 5.875 GHz

In the United States the use of these bands for communication purposes is regulated by part 15 of the FCC rules.  These regulations cover such things as maximum transmitter input power for mobile as well as point-to-point communications.

Yes but the regulations do not allow operation of home built transmitters in these bands, all transmitters must be "type approved" it is only the operation that does not require a license.

So let's see if the OP has got any balls.

Jamming or causing "Willful Interference" to another radio signal for any reason has always been illegal.
IT is also illegal to unintentionally jam any radio transmission for any reason.
There are exceptions to the law but the applicable scope is so narrow that they aren't worth mentioning.

If the FCC went around checking interference they would find appliances shorting out in homes producing interference. Your PC is one program away from being a jammer, yes its that easy!

Signal jamming devices pose significant risks to public safety and potentially

Then you should be able to figure out that building your own is not an 'out'. Whether you buy or build you own gun, if you shoot someone it counts.

Your examples/exceptions are a joke BTW.

If I caused enough interference to be noticed, the FCC would let me know and fine me. That's not guesswork either. My circuits don't run enough power to compete with my open-box PC and it doesn't cause noticeable interference to my TV or radio.
There is such a thing as _proportion_ and in the case of interference it has to reach far enough to be detected to matter. You don't seem to know the difference between what matters and what does not.

Will your jammer be so short-ranged as a normal PC, or short in an appliance or some low power Arduino project I make?  Or will it be powerful to jam FM radio signals at any useful distance?

I'll tell you what S_Flex, I DO work for the FCC as an engineer.  You think I don't know the FCC regulations?  Here's a list of our field offices. http://transition.fcc.gov/eb/rfo/FieldPhone.html (http://transition.fcc.gov/eb/rfo/FieldPhone.html) I DARE you to call any one of them and tell them that your little jamming scheme is LEGAL, give them your address, and DEFY them to do something about it. 

Since I KNOW that you only "have a brass set" while you are hiding behind what you THINK is the anonymity of a forum posting and would never actually call us, for my part, I'll initiate the process to have our Special Counsel for the Spectrum Enforcement Division get your IP address from the forum moderators, use that to get your REAL name and address from your ISP, and start an investigation based upon your PUBLIC admission regarding carrying out a pre-meditated jamming operation with full knowledge that your actions are both harmful to radio communications and illegal.

From Code of Federal Regulations, title 47, part 15:

§ 15.239   Operation in the band 88-108 MHz.

(a) Emissions from the intentional radiator shall be confined within a band 200 kHz wide centered on the operating frequency. The 200 kHz band shall lie wholly within the frequency range of 88-108 MHz.

(b) The field strength of any emissions within the permitted 200 kHz band shall not exceed 250 microvolts/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector.

Elsewhere in part 15 is a requirement that measurements confirming compliance be supplied to the nearest FCC office if the device is not a type-approved commercially produced unit.

If you are in compliance with those regulations, you are set until the first time there's an interference report from anybody.  With the second report, it becomes intentional interference.  The default fine is $4,000 per monitored transmission.

Is that sufficiently concise to end the shouting match?

I doubt it because he does not believe that that particular law applies to him. He believes that something at state level trumps that law. He is taking freedom of believe to a level that is beyond belief.


Well in the USA there is and always will be a lot of issues and opinions around States and individual rights Vs Federal powers granted under out Constitution. It's kind of ingrained into our Constitution that the Founders wanted a rather limited and focused Federal government, given only specific enumerated powers, the rest (even if unstated) being reserved to the States and the People. There is no question that the US Federal government has grown to dwarf the powers of the State. But in the case of RF laws it would appear to clearly fall (IMO) under the common commerce clause of the Constitution and could not be managed by 50 individual states.
