Quoting from the ad: "The BG-E8 signal jammer weighs only 2.3 kg. The Texin jammer consumes 60W of power and has a single channel 3-4W transmitting power." And costs $119.99.
I understand that they are trying to describe the environmental conditions under which it can operate (probably) but it made think of a deliciously moist signal jammer. :)
I understand why they would have a humidity max, but why do they care about the min?
I read that to be “They only started looking for it once it started pissing people off”.
Just because the knowledge is there and there's a paper trail doesn't mean anyone will _actually_ put the pieces together
Radio Caroline are still around though, they've actually done pretty well recently with fundraisers. Their old pirate ship is still used for broadcasting but these days instead of using the old valve transmitters aboard they use 4G to relay their signal to (ironically enough) an old BBC World Service site which is then broadcast on 648 kHz with a much more modern unit. They've just been licensed to turn up the power considerably too so they'll be receivable in much more of the UK and northern Europe than they are currently soon.
It's kind of interesting to see new AM stations popping up in what's otherwise a dying band. I've always thought it's a bit short-sighted to get rid of AM because in a real national "shit hits the fan" scenario where power and networking are heavily affected it's an efficient way to reach lots of people. You can even build an AM demodulator out of a razor blade and a pencil if you're in proper trouble! I expect by the end of the decade the only things left on AM will be enthusiasts like Radio Caroline and hobbyist pirates (there's quite a few of these in the Netherlands and Greece).

Great soundtrack BTW.
I think this is the story: https://www.cnet.com/tech/computing/man-put-cell-phone-jamme...
Or wouldn't they take extra 10% cut from CIA for sharing the data?
But that's the point - western authorities can't do anything to shut them down and Chinese ones don't care either. Sending a list of buyers is effort and takes time....so why bother?
I mean obviously we're just speculating, I just mean that a random Chinese website would have no reason to respond to such a request from say an American authority(and it's probably unlikely that anyone would ask, seeing as in a lot of places just owning such a device is not illegal, using it is)
I specifically said dealextreme which isn't anywhere near being a "largest retailer". Also with Alibaba you can just message the seller directly. So I don't see how having foreign agents working at a place like Alibaba would help in the slightest.
Either way, like I said, I would be surprised if any agency was spending any effort tracking this, the devices themselves are often legal to own and the cases of abuses seem rare.
“ Here we have an excellent device for you. Just have a look to understand what it is from the Texin brand. Did you get what it is? I think you got it. Yes, you are right that it is a signal jammer produced by the Texin named Texin BG-E8 which is crucial from different perspectives. If you are in search of a fantastic signal jammer by you can work properly, then I should say that you are in the right place.”
Further, I imagine you turn up the amount of power of the jammer until the person on the phone gets bad reception.
There are also defect detection systems that rely on radio transmissions to indicate if a train is for example dragging equipment.
Loud conversations in a public place are annoying, but guess what? it's a public space, and you don't have a right to quiet there, let alone exclusive control over radio communications. The sheer entitlement in your post is astounding.
How does this stuff makes it to the USA?
I was importing small PCBs and components from china when I was 15. Most of the time the seller would write "gift" on the package.
If the seller writes "wifi router" on the box, is customs gonna doubt it? Sure, one in every X should be getting checked by whatever department looks out for "dangerous electronics" but it's easier than you think.
If no american is shipping boats of these into ports to sell, I doubt customs even looked at this person's small box with one device in it.
Though they since cracked down on many things
I've bought from there myself with shipping to the US, and I doubt every package gets inspected at customs. Among other things they sell a lot of 3d printing and electronics stuff.
