This made news in the U.S. a few years ago because Ajit Pai had the brilliant idea to allow so-called "5G" telecom service on frequencies too close to those of GPS. I don't think this case is resolved yet: https://physicstoday.aip.org/news/new-5g-exemption-may-jam-g...

One can tell that this is 'from far away'. Europe was hoping that Russia, in their own interest would pursue peaceful cooperation, even when Putin was already talking about 'spheres of influence'. When Russia invaded Georgia, Europe turned the blind eye and was still hoping for peaceful relations with Russia. When Russia annexed Crimea, same thing. Even when Russia was pulling together forces along Ukraines border an…

No one gives a fuck what russian residents are thinking about it. And if they start to talk about issues - police will quickly force everyone to shut up.
Thats true, but its also true that most russians support this war. Maybe they dont say it, but they are the soldiers in the trenches, mechanical engineers building missiles, software developers building their military software, Oil/NG workers that fund the war and so on

No? Old AM radio required only rectification. You can receive it with accidental diodes.

Maybe there are reasons Europe is pulling away from the US? The current US president has threatened to invade European territory, is attempting to impose Russia's preferred "peace" plan on Ukraine, and has recently relaxed sanctions on Russia. He also consistently denigrates the military support Europe's given to the US in the recent past. The US has basically cut aid to Ukraine to zero, while Europe continues to sup…
And? When the Russians invaded Georgia in 2008, Europeans inked a deal for a second gas pipeline with them, Nordstream 2. When they annexed Crimea in 2014, Europeans went to the Sochi Olympics (which happened that same year ) and went to the World Cup in 2018. And this is before you take into account the dozens of smaller incidents. Those aren't "threats to invade European territory", not even ones that were ignored…

That jamming near Kaliningrad must surely be impacting the Russian residents as well, right? Unless it is very carefully aimed which seems unlikely since it is also trying to cover a very large volume.
>must surely be impacting the Russian residents as well, right? They don't give a fuck. Was watching a youtube video by a russian the other day talking about war & sanction impact and things like ride sharing apps literally say on screen the location is going to be wrong and to select pickup spot manually. It's just assumed to be fucked as a given even at an app development level

Why, the Second Chechen War.
okay, let me rephrase that: would it have taken two wars to subdue that tiny, sparsely populated country had that country been armed with nothing but sticks, stones, and Molotov's?

I wonder why they call this specific discovery “jamming”. What they found is a relatively rare burst transmissions over roughly 5MHz of spectrum of something looking like a 12ms cyclic prefix with spacing related to 150 seconds multiplies. I would suspect it is some sort of sync or data close to L1 GPS frequencies, that as a side effect causing lower CNR for the GPS receivers. Btw it is only 10dB, which also I can’t…
