Not only are cell phone used for emergency purposes, but there is also public safety in the same bands.

One of the buildings is destroyed. There are some antennas that were damaged on some of the towers. Our biggest challenge was power. There was a malfunction on the backup generator that needed to be repaired so we were running on battery for a while. We have this video of the fire. th-cam.com/video/QeSH2NIPCmk/w-d-xo.html. This is the reason that brush is cleared back from the buildings.

@@mra-raycom6982 that is one good video, should be actually part of the recent Videos as well, bcoz most ppl like me, watching the video on mobile phone, will most likely not visit your channel and see teh rest of the videos. Thanks for the link!

No. As previously stated jamming is illegal, and you are not going to to get permission from your state to do it. In the tests on this device precautions were taken to make sure there was not interference to anyone else. Frequency spectrum is a limited and shared resource. For that reason, and keeping our licenses in order we don't help people circumvent the law, or good operating practice.

It would depend on the device, frequency and the distance. For the most part, they are both illegal, and a waste of money. You also have to consider that devices such as air tags are not GPS, and would be completely unaffected. The location of air tags is reported by passing phones, not a GPS in the device.

@@mra-raycom6982 oh, wow. There's a video of a guy using an old cordless phone to supposedly block gps ? I'm being stalked, they're ruining my life. It's been going on for years and they're wearing me down.

That was the attempt. There was a sheet of ice under the snow that got the better of us, along with a 60mph wind. We have been back since and got the site repaired. On the snow was gone my SUV would do it

We are on Potosi, but we don't own the site. We have sites on Cajon mountain, Sierra, Santiago, Lukens, Tecopa and Tejon. We have equipment at Heaps Peak, Bertha Peak, Toro, and many others. A list of the sites is here mra-raycom.com/mra-sites/, and we are always expanding. At some of the sites we have drone video so you can see the view. Cerro Gordo is at 9200 feet, but is also out in the middle of nowhere. I have never worked 10GHz, but I would think views over the cities would be an advantage.

@@mra-raycom6982 From that site, where can you link to directly with no issue? What other sites? I was kinda thinking about what it sees.

We have a lot of those amps. Since Chip retired they are like gold and we repair them when we can. Eventually we will need a replacement.

They are illegal to use, so why would you buy one? There are a lot of games played by importers also and it would take a while digging through bulletins and certifications to determine its actual status.

It goes thru Canadian custom, bought several, and it doesn't completely jam the gps signal, you only lose it..

@mr_credentials I meant US. It's illegal to purchase in US.

They are only intended to jam gps signals to prevent surveillance, rather than jamming cellular or WiFi signals.

Lol

Some of the devices store locations in memory to be read later. That can't be jammed. Other devices use the cell phone network. Jamming the cell phone network is a very bad idea. There is a very wide frequency spectrum in use by cell phones and it would take a lot more power. The result would be fouling up cell phones over a few miles, including yours.

@@mra-raycom6982Shows you how much I know. I was thinking about just blocking the signal in maybe a 10 foot radius. i see your point about the memory.

"Everything is vibration and frequency" is common in new age philosophies, but not really descriptive or useful in technology. There are piezoelectric resonators, which need to be cut to a specific physical size for a frequency. The bandwidth would be too narrow to cover an entire band. There is stimulated emission, but that is also very narrow and not tunable as it is characteristic of a specific element and the energy states of it's electrons. Either way requires a power source to generate a signal stronger than the incoming GPS signal, so no, you are not going to find a natural substance that jams GPS signals. You could block the signal with a faraday cage, but building one around your car would render the car undrivable. We have to go with science rather than mysticism here.

No, and as has been said jamming is illegal. Drones operate in a different part of the spectrum.

*NO ...NO MUST BUY THIS "JAMMER" WITH (8 SMALL ANT) ...* *THINK IT IS 200-300 U.S.D * *THEY CAN DO .. FROM YOUR PHONE TO YOUR CAR /SAT TV /GPS ... AND* *YOU WILL FIND .. (DRONES)* *THEY SEND 1 WATT / 5 WATT ...OUT ... MORE IS BETTER* *(OR ASK SOME SELLER ...!! YOU NEED DRONE JAMMER)* *GOOD LUCK*

To evaluate would require testing. It is still going to be illegal, and potentially destructive if critical communication is jammed. @@netautorisationnetautorisa545

You could throw a rock or Sierra hotel oscar oscar tango It down

Do you know where to get a reliable jammer? I feel like an ex has a GPS tracker on my vehicle.​@netautorisationnetautorisa545

(YES THIS IS.. CRAP) HAVE A JAMMER "SOME WATT OUT" IT RUNS A "LONG WAY" LIKE A "VHF RADIO" ... (AND NOT TO FORGET WHAT ANT ... YOU USE) NEXT ... USE A "AMP" !! THEN (NO LIMITS) ... BUT YES IS NO "TOY" ... MUST BE A #REASON .. TO POWER "UP" ... ... IS NO "JUST FOR FUN" ....

Hello, can you help me? I am a university student. I want to make a GPS jamming system as a graduation project, but do you advise me to do this work or not? If I say yes, can you give me videos teaching making it? ​@@netautorisationnetautorisa545

That is actually a pretty odd assertion. I tested it on the bench, and in the vehicle. I measured the signal levels and the bandwidth. The reason it didn't work is two fold, and pretty evident. First is that it doesn't cover all the GPS bands so the device simply picks up from the other two bands. Second is that the signal is very weak. at 3 feet it measured -95dBm. Since the expected from the GPS system is -125dBm, it may have worked if the GPS were in the car and it had covered all the bands, but the additional signal loss from the distance outside the car and the loss through the car body would make it ineffective against an externally mounted tracker, or one with an external antenna. The video demonstrates pretty definitively that it does not work, but if you would like to send in one that you think will, I would be happy to test it on another video.

Cool voice though

shhhh..you're yelling

sounds like batman lmao 😅😅

Wasn't there

Who said I wasn't? KE6TNM. Also in the videos WA6DPB, W6RE, NW6B, KF6PHX, W6MAF and WA6YRE

@@mra-raycom6982 Easy hotrod...KE6TNM. The advice is good even if the person watching the video is not a ham...I did not mean the poster of the video was not a ham or the accomplices that helped make the video were not hams. Something was lost in translation.

First, as I mentioned in the video, jamming is illegal. If you jam the cell phone network, you will be interrupting the connections of yourself, and everyone around you. Now suppose one of those calls is an emergency. Next, you don't know what frequency the device is on. 2G, 3G, 4G, or 5G are not frequencies, they only designate a protocol. The actual frequency will vary depending on the model of the phone or device and the frequencies that are licensed by the FCC to the service provider in that area. They could be operating in several bands from 600MHz up to 21 GHz. Most phones are multi band so if the connection is interrupted on one frequency, it will jump to another. On top of that, there are multiple ways to handle the data. Some trackers will store the data in memory for later recovery. Some may use the cell phone system. WiFi is possible. There are also Bluetooth devices that will use passing phones running an app to send data. A couple weeks ago I ran across a gas pump that was transmitting something in VHF spectrum. Pretty much anywhere in the spectrum could be used to send the data and if you attempt to jam all of it in a 100 mile radios, your going to be noticed and your jamming signal will be tracked. It is harder to jam a transmitter since it is the receiver that would need to be captured. The principal behind the GPS jammer is that the receiver is in your proximity. For data transmissions, the receiver would be at a cell site, mountain top, wifi access point, or someone's mobile phone. It would take much more power.

@@mra-raycom6982 It's illegal in America but maybe he doesn't live in America.

@@parkerbohnn Possibly, but do you know of a country where it is legal to jam? Any of them I have looked up are pretty consistent on that point. The closest I have seen is people claiming there is no enforcement.

@@mra-raycom6982 No one will know if you're blocking the 1.6 gigahertz band. They only care about radar detectors.

@@parkerbohnn Actually radar detectors are of little use because of the burst mode that the radar units use. By the time you get the detect, it is too late. As for jamming "No one will know" is not true. There may be many circumstances where it is not noticed as with this non-functional jamming unit. However if you cause a problem, there are people who can and will track it down. I know of a group working on such a project for the last few weeks.

Yes, it is.

Thanks 👍

We have some historic pictures also, at least of our building, maybe a couple others.

@@mra-raycom6982 I would like to see of the older photos.
