Thanks

aaahem,duznt land?

Christos Perivolaropoulos Thank you. 👍

Why are the planes tracking signals only picked up at a certain distance from the coast....They seem to appear out of nowhere

I liked the little talk

They just don't care enough, they hacked it all together 😂

Its like when you're doing calculus that you forget how to do the simple stuff

I have to assume its blatant interference from so many pocket devices xD

You know what they say......Find something you truly love to do, and let it kill you! Such irony!

They are required by the hotel to use a single contractor to record audio and video.

What happened, then.....?

wot like spit fie aah carnet eer ritz hea?

u wot

@@user-nx8vp5sy5d pics or it didn't happen :)

If you still find SDR interesting, consider reaching out to the guy. The world is smaller than you think, and paying a consultation fee makes it even smaller

Any books you could recommend?

It was too simple so they brought in a conference center media multiplexer as a challenge just like the heist con episode of Rick and Morty

Epic!. I want to do this now! :)

***** yup it sure does :D

***** be aware in some of those you may have solder 2 very fine wires to the ic directly they are like 30 gauge i think

***** im sure you will probably find the signals of the encrypted channels good luck

***** i guess you could put the incoming data into gnu radio software and make a little program that spits out the data to a screen and you would see the hex data in text format then its up to you to decrypt it haha

but there some things that are uncrypted like old pagers and you could easily read their messages directly (use gnu radio to display the text)

who cannot get what to work? is your main computer also a $5 RPi Zero?

DutchEllie never thought about that, but you’re right

Sorry to hear that...thanks for all that you do. Keep up the good fight! Let me know how to reach out outside of the tube. Thanks

I'm not sure if you were joking but I found a pattern in that noise and it seems to be repeating every 3m33 or so. After translating each bits, this is what I got: "oHg5SJYRHA0" I don't know what it means tho...

@@Reth_Hard "oHg5SJYRHA0" kzfaq.info/get/bejne/pa6XaLZ7vriscWQ.html = 3m33.

@@FlatFact Gotcha! :P

Anyone know any valuable resources for learning more about RF. I've been intrigued.

There are so much software and hardware available if you wanna mess with SDR, and in so much price ranges. I read that the HackRF One from great Scott's gadgets is good for beginners. It covers a large frequency range (1Mhz to 6Ghz if I'm correct), and it's affordable, compared to other RF transceivers (about $200 for the official one, but since it's open source, I'm sure you can find unofficial copies even cheaper). Plus, it's compatible with GNU Radio and most radio softwares. I'm planning on buying a HackRF as soon as I have some money c:

Hypothetically, just a thought.

@@kornbread5359 - First: clever choice of name. Second: You are on the right track - I recall reading an article describing a similar technique being used in a somewhat novel RF transciever. I'll summarize briefly, as I can't find the article (maybe you'll have better luck?). A major constraint on bandwidth is frequency space - if one guy is talking on a channel, others can't be, so it becomes a competition. RF antennas, as conventionally designed, are receiving (interacting with/modulating in accordance to) the electric charge component of the transmitted signal. However, electromagnetic signals are electromagnetic - they have both an oscillation in electrical and in magnetic field. The magnetic portion of the signal reflects information content of the electric, however it is out of phase with the electric portion by some offset, determined by the transmitting antennas design. What was realized is that an antenna circuit could be designed to capture both the electric and magnetic state simultaneously, allowing that offset to be measured in real time. Simultaneously, they designed an antenna where the offset could be tuned. This means that (potentially in combination with techniques such as mimo) multiple devices could be transmitting on the same frequency at the same time, without use of time division, and the individual signals could be isolated. Potentially thousands of signals (or more) could be overlapped on the same carrier. ... I really wish I could remember the insititute name, because I'd love to know how that's progressing.

Also, great talk.

He asked if you could broadcast back on that frequency.

Cone Head - A lot of DefCon talks are like this. They gather hundreds of the best hackers in the world together and they can't make a video projector work. SMH

Someone probably DOSed it.

Lol noob

wivoota parashoot gp ez?

I actually had a several months long E-Mail discussion with a flat earther where I finally convinced him that satellites are not balloons after he measured their Doppler shift with an RTL-SDR. He thought they were really fast planes then, so I was not entirely successful.

They often do. But you are inside a metal tube (not exactly a Faraday cage, but still more opaque to RF than, say, your flat), so the very weak GNSS signal may not be picked up well by your phone's receiver. If you use a bluetooth external GNSS receiver, and you push it up against the window, you can probably get decent signal. BTW, that's also the reason GPS doesn't work underwater.

Because the earth is flat...

Civilian GPS is automatically disabled for any device that’s traveling over 1200mph, or is above 59,000ft. It’s to prevent it from being used by rogue/unsanctioned ballistic missiles. It wouldn’t be relevant on a commercial aircraft, but still fun.

what do uhf and vhf sound like?

Stop telling people. You're going to make us angry.

You have schizophrenia my friend. Please seek a mental health specialist.

It's a meme.

Renee Dole Finley Besides a tall pole with great directionality, getting relevant authorities to identify disturbing transmitters blocking your reception is probably your best bet.

Forced me to look up 'cemtrailing plane'. I had no idea people could believe such nonsence. I feel very sorry for you 'Sir'. Here is hoping you are not late for school tomorrow.

you mean a trail of condensation, right? RIGHT?

Gov shouldn't ban anything

Perhaps the government should also ban locksmiths? Or perhaps the gov should insist on people and companies secure their shit properly. You can't ban these devices because even if you did, there's still electronics outlets to make them and criminals will do just that. By banning it you just sweep the problem under the carpet where criminals can better hide. It's highly small minded of you to call "ban it". Unless you're a criminal trying to stay covered and not have these security lapses found and fixed?

they're passive (listen-only) devices. As long as you're only receiving and not transmitting, there's nothing wrong with that. I mean, the radio waves are willfully being transmitted out, and technically are 'trespassing' onto the listening device, and unencrypted at that. So yeah.

I know I didnt type bulau booo....wtf is that
