In most cases they have an Return To Home feature if they lose signal. 

Maybe on a million dollar drone but not private ones.

Incorrect.  A great many of the hobbiest ones have that feature. 

I doubt it is a very viable amateur system because it would also have to have a object avoidance system as well to be reliable and that takes more logic and equipment and $$$. Could it be done? Yes. Is it easy to do? No.

Feel free to check out the many quad-, hexa-, and octo-copters out there.  You will find that a great many of them have a RTH feature.

Just google it and you will find the answer, however it is not legal. Your choice.

Perfectly not legal.  From the document:

"Jammer which blocks GPS, Cellular communication and/or

WIFI are illegal in the United States, so this Jammer design is

for educational purposes only and is not for commercial or

personal use."

And actually in the US jamming ANY kind of communication signal, digital, analog, telemetry, command & control,etc are illegal, as is jamming anything to do with aircraft.

If it were me, I wouldn't waste my time and effort trying to defeat command and control, just drag out a good electric pressure washer.  If the thing gets within 25 to 30 feet of the ground, just blow it out of the sky with high pressure water......  Relatively safe.  Even if the craft makes a hard landing and you have to put out a battery fire.  As a added bonus, even if it manages to get away, you've probably soaked the electronics onboard pretty thoroughly.

be sure to explain to any crash investigators that you belong to the water worship religious sect whose members periodically, in spontaneous fits of inspiration, use hoses to spray water into the sky to celebrate water in all of its wetness.  also, place a sign in your front yard warning others that you belong to the water worship church and that operation of drones and other RC aircraft at this location is probably a bad idea.  Tongue

I would have to guess jamming a 'Drone' would be quite illegal and that you would be responsible for any damages or injuries that would result. Some of these can get pretty big, heavy and expensive and can do some serious damage if they crash into something.

If someone were flying one of these close to my house I might try to look around first for the person at the controls and simply ask them to go fly somewhere else. If that doesn't work? Then call the police and let them deal with it.

I fly r/c aircraft.. I always fly away from people and houses. We have a few parks nearby and I'll either fly early morning or late afternoon providing the field is clear. Granted my models are electric but they could probably still cause some harm to someone or could take out a window if too close to a house. Gas aircraft have been known to kill. Most recently in the last year or so one person lost the top of his head in New York - killed instantly from an RC heli.

Well...I prefer Strawberry but, I guess, Grape would be good too!  Just be sure to wipe it off your feet before you go back in the house!

Drones are getting out of control because being to by it does not mean you will use it properly. I read that yesterday some idiot crashed on in Yellowstone National Park in its largest thermal spring!! Never mind that they are banded in national parks. Depth of pockets does not related to brains it seems. Device is still in bottom of pool which is about 200 feet deep and near boiling.

My only thought is that if you're caught, the FCC will slap you with a fine and take away your amateur license.

Otherwise, when I want to make sure I have privacy, I close the blinds... Maybe some sort of 1-way window treatment would be more appropriate for more sensitive rooms?
Not quite. The FCC would do no such thing because unless specified, this would not occur on the Amateur bands. Your interpretation of the how the FCC works is not correct.
Oh?  Well, let's see now...

Jamming, more specifically causing deliberate interference, is a violation of multiple FCC rules across multiple services.

Transmitting outside of the Amateur bands?  And outside of the parameters of your license class?  Also a violation of multiple FCC rules.

Your potential jamming device would be transmitting on frequencies authorized for multiple users, including other Radio Control users, other Part 15 users, and depending on the frequencies involved, GMRS and other services as well.  So what happens when your device takes out the "drone" (and despite the media, quad copters are not "drones"), and also takes out a dozen unrelated users at the same time?

What happens when, due to your actions as a jammer, the user/owner/operator of  the RC device (presumably a quad copter) loses control, and the device crashes -- causing damage to property of an innocent third party?  Or worse, crashes ONTO said innocent third party?

I'm truly sorry that some ignorant users are causing you problems.  But your proposed solution?  The "cure" is 100X worse that the "disease"

So. Buy your own helio/drone, learn how to use it as a sub-hobby.
when a offending helio/drone invades you property fly out to meet it and have a...wait for it...drone war.

It's also a violation of some portions of the Communications Act, which could bring criminal charges.


You know guys...

while catching up on the thread, something came to mind...

I recall an actual drone being used by the military, that did have a return to home feature, had its command signals jammed and it's GPS signal was supposedly hacked (because it was capable of using an encrypted GPS and was assumed by the press to be using it) and "fooled" into landing in enemy territory...

I've noted my concerns in other forums about unmanned vehicles being hacked and forced to venture to, land, or crash in other locations than the operator intends.

http://en.wikipedia.org/wiki/Iran%E2%80%93U.S._RQ-170_incident

It's a problem when people start to worship technology so much, that they feel it is more important than other peoples' safety, privacy, and peace of mind.

Agreed.

It's only a matter of time before someone in a 'stand your ground' state perceives a hobbyist drone as malevolent and................

You know those private drones use WiFi is some capacity for control or video downlink. IF you were to defeat the safety switch on a small microwave oven and have door open facing drone it would jam it because it is in 2.4ghz WiFi spectrum and you would have a 600+ watt jammer without building one. You would not want to be directly in front of it though. Just a thought.
